Dolphin Nautilus

You don’t have to be in tip-top shape to drop and retrieve the Dolphin Nautilus from your swimming pool. This Performance model only weighs 16.5 pounds when dry and about double that when wet.

However, like all of the Dolphin robo pool cleaners, the Nautilus quickly releases water when lifted. The 60-foot cable features Maytronics’ ingenious swivel system that fully rotates to avoid knotting.

Dolphin Nautilus

Designed for in-ground swimming pools, the Nautilus is also powerful. It’s equipped with a pair of brushes that scrub and loosen as they rotate on dual tracks. Thanks to its strong suction, the robot can lift all sorts of debris, both light and heavy.

With the Dolphin Nautilus, you get full-level filtration that captures fine particles and ultra-fine particles. Filter maintenance only takes a few minutes.

Agile and efficient, the Nautilus CC is designed to clean your pool, effortlessly

The filters snap into a frame, which loads from the bottom of the robot. To remove and rinse them, simply pop off the filters from the frame.

The Nautilus always navigates along the most efficient route, taking the shortest detour around obstacles while it moves in a logical pattern.

Maytronics rates the Nautilus for use in 50-foot or smaller swimming pools. Even when used in pools near or at the 50-foot maximum, the time it takes the robot to clean is short at just 3 hours.

For the controls, simplicity rules. The power supply has a looped carrying handle and an easy-to-read digital screen.

There is only one button, which starts and stops the robotic cleaner. If you’re worried about your electricity bill, don’t be. It only costs pennies a day to run the Nautilus.

Noticeable Features

  • Easy plug-and-play features
  • Made for in-ground pools with a length of 50 ft
  • Guarantees no random movements with CleverClean Technology
  • Will clean pool walls and floors
  • Equipped with dual brushes for stubborn dirt
  • Bottom-load filter cartridges
  • High suction rate
  • Power cord with swivel features

Dolphin Nautilus Robotic Pool Cleaner

Dolphin Nautilus CC

It may be rather lightweight at 14 pounds, but the Nautilus CC can power through grime on vinyl and fiberglass pool walls and floors like nobody’s business.

The sole brush is of Maytronics’ Active variety, meaning it spins twice as fast as a standard brush. Its recessed handle makes hassle-free work out of pulling the Nautilus CC from your pool, and dual track belts prevent slippage.

Dolphin Nautilus CC

With this Performance model, you get one layer of filtration. However, you can switch between a fine and an ultra-fine filter whenever you wish. The filter loads into the basket from the top of the robotic pool cleaner, and the basket has a handle for easy removal.

Due to their large size, sizeable debris loads are no issue, and the suction is powerful enough that it can even lift small pebbles.

A 2-hour cycle time makes the Dolphin Nautilus CC super-quick, and it only takes one button press to start a cycle. If you chose, you can delay the start time of a cycle from the touchscreen power supply.

With its superior scrubbing and filtering capabilities, you can relax knowing your pool’s floor and walls are left exceptionally clean with the Dolphin Nautilus CC

Other functions on the power supply’s control panel include a three-way weekly scheduler and a cleaning mode selector that toggles between a fast and a regular cycle.

Maytronics takes a different approach to cable care than a mechanical cuff. Instead, the Nautilus CC’s floating cable is controlled by anti-tangle software, which is just as effective.

The inclusion of CleverClean Technology allows the robot to move in a methodical pattern, covering every square foot of in-ground pools up to 35 feet.

Noticeable Features

  • 60-foot cord
  • Ideal for inground pools up to 50 ft
  • One-button operation
  • 8X more energy efficient than suction and pressure cleaners
  • CleverClean technology
  • Patented anti-tangle swivel cable
  • Dual-scrubbing brushes
  • Large top-load filter cartridges

Dolphin Nautilus CC Plus

Just push a button and let the Nautilus CC Plus do its thing while you kick back and relax. The power supply’s controls are simple and straightforward.

You can set the robotic pool cleaner to run on one of three schedules, including every day and alternating days. The robot is lightweight too at a mere 19 pounds, and its lifting handle makes it easy to pull the Nautilus CC Plus from the water.

Dolphin Nautilus CC Plus

Filter maintenance is a user-friendly experience. A panel on top of the robot opens to reveal two types of filters – fine and ultra-fine.

Simply pull them out, rinse them off and reinsert them. Due to their large size, the filters in the Advanced Nautilus CC Plus are able to trap a lot of debris before they need to be cleaned.

This robot is one of Maytronics’ fastest models for in-ground pools to date. No random, nonsensical movements mean that the robot maximizes every cleaning cycle. In fact, one cycle only takes 2 hours even in pools as large as 50 feet.

It won’t miss pockets of dirt either as advanced algorithms leave no part of the swimming pool undetected.

Wherever the Nautilus CC Plus travels, it won’t need your assistance. A rotating cuff on the 60-foot-long cable prevents tangles from occurring.

The Nautilus CC Plus is an Internet-only model, sold exclusively online and is not available in retail stores.

Dual-scrubbing brush bars practically wipe away algae. Designed for use on pool walls and floors, the CC Plus robot’s brushes rotate on a track system that provides an excellent grip on surfaces.

Noticeable Features

  • Weekly cleaning scheduler
  • Strong brushes to remove persistent dirt on the wall and floor of your pool
  • Top-load cartridge for easy filter replacement
  • Provides complete coverage of your pool using CleverClean
  • Easy, single-button use

Dolphin E10

User-friendly is the best word to describe the Dolphin E10. You can get the robot started in just two steps.

First, drop it into the water. Then, press the power button on the supply box’s touch panel. There are no other buttons, which means there is no steep learning curve for the controls.

Dolphin E10

The E10 is also a fast worker. In a mere 1.5 hours, the robot completes an entire cleaning cycle around a 30-foot above-ground swimming pool.

The robotic pool cleaner can only scrub and suction pool floors, but it’s capable enough to remove thick grime caused by algae and bacteria yet gentle enough to not damage fiberglass or vinyl liners.

Another feature every pool owner will appreciate is the Dolphin E10’s weight. At 13.9 pounds, you won’t struggle when lifting it from the water.

To help you lift it when wet, the robot is affixed with a recessed handle, and it sheds water quickly as you pull it from the pool.

The E10 is designed to clean above ground pools, effortlessly

Inserting and cleaning the filter is just as easy as removing the robot from the water. The hinged lid on the top of the E10 conceals a click-on filter basket with a raised handle. All you have to do to clean the fine-particle filter is rinse it with a water hose.

A rapidly spinning brush and a 4,500-gph suction rate allow the track-equipped robot to collect a lot of debris per cycle.

Thanks to CleverClean technology, the robot scans and plans while it maneuvers around obstacles, making the most of every cycle minute.

Dolphin E10 Robotic Pool Cleaner

Dolphin Triton PS

Fast, efficient and customizable. In part, the Dolphin Triton PS operates on Maytronics’ PowerStream technology, using water currents to maintain its grip to the walls of in-ground pools. It also exercises lightning-fast decision-making by accounting for obstacles when the robot comes across them along its planned path.

Dolphin Triton PS

Nothing but clean walls, floors and a waterline will be left after the Triton PS completes a cycle. The Advanced Dolphin robotic pool cleaner has one standard and one Active rolling brush, so it can easily remove thick buildup.

Due to the inclusion of an Active brush, it will only take 2 hours for your pool to go from dirty to dive-in ready.

Fine particles like dirt and sand won’t bog down the robot. Inside of a top-opening compartment, there is a filter basket. Extra-large in size, the basket also excels at trapping bigger particles, including leaves.

When the basket becomes covered in debris, lift it out by its tote handle and rinse off the filth.

Built to deliver a deep clean. The Triton PS is powerfully nimble on vertical surfaces for intense wall and waterline scrubbing

Cable knots are the bane of everyone who owns a robotic pool cleaner unless that cleaner is a Dolphin. As with most Dolphins, the 16-pound Triton PS’s cable swivels in a complete circle, making tangles a problem of the past.

Big pools are also a non-issue for the Triton PS. Thanks to a 60-foot-long cable, the robot is able to maneuver to clean a 50-foot pool from edge to edge and corner to corner.

Maytronics gives you three choices for how often the robot cleans your pool. Via the slim touchscreen power supply, you can set an every day, alternating day or on-each-third-day schedule.

Noticeable Features

  • Good scrubbing power
  • Large top-loading filter basket
  • Saves 8x energy
  • Schedule your cleaning with ease
  • Lightweight and easy to use
  • More value for your money

Dolphin Premier

Premier’s Multi-Media filtration system consists of an ultra-fine cartridge and a fine-debris cartridge that load from the bottom in a snap-apart basket.

You also have the choice of using a disposable debris bag, which comes in handy when leaves scatter the waterline. An LED indicator lets you know when it’s time to dump the basket.

Dolphin Premier Review

As part of Maytronics’ Advanced line, the Premier is suitable for large in-ground swimming pools of 50 feet. CleverClean Technology and Smart Nav help the robotic cleaner look for and avoid obstacles without missing any areas.

Two high-torque DC motors keep the robot humming along to clean your pool in 3 hours. The 60-foot cable swivels 360 degrees to prevent tangles.

In just 10 minutes, you can set up and use the Premier robotic pool cleaner. From the power supply box, you can begin a cleaning session whenever you choose.

The Dolphin Premier scrubs the floor, walls, and waterline and removes unwanted debris

There is also a scheduling function that you can program to automatically clean your swimming pool once a day, on alternating days or once every three days. The remote is an optional feature that offers from-your-seat control; however, the plug-and-play nature of the Premier makes a remote unnecessary.

With a pair of wide rolling brushes and 4,500-gallons-per-hour of suction strength, there is almost no gunk or debris the Premier can’t lift and remove.

The rolling brushes rotate on tracks, giving the robot a firm grip on the floor, the walls and along the waterline. Despite their powerful scrubbing action, the brushrolls are safe to use on most surfaces, including fiberglass, gunite, plaster and vinyl.

Noticeable Features

  • 60-ft cord
  • For in-ground pools up to 50 ft
  • Cleans within 3 hours
  • 3-year warranty that’s not prorated
  • Multi-media filtration

Dolphin Quantum

With the Dolphin Quantum, Maytronics focused on navigation. This robotic pool cleaner contains a SmartNav 2.0 microprocessor to make calculated movements.

The inclusion of three PowerStream jets allow the robot to climb 90-degree walls easily, and HyperGrip rubber tracks keep the Quantum adhered to the surface at all times.

Dolphin Quantum

Its ability to travel in reverse means the Quantum cleaner won’t miss a single piece of debris during its 2.5-hour cleaning cycle.

The 60-foot cable is designed to turn in a complete circle, so the robot cleaner won’t get hung up on itself. Since the cable is covered in friction-reducing thermoplastic rubber, it won’t fray or kink.

The Dolphin Quantum is designed to combine optimal convenience and efficiency with powerful scrubbing and filtering capabilities

At 400 square inches, the filter basket is huge. The fine and ultra-fine filters are inserted from the top of the robot, and they snap off for quick rinses. An LED alert helps you maintain the filters. With a filtration rate of 75 gallons per minute, you’ll never have to worry about an obstructed water flow.

Inside the Dolphin Quantum, there are two belt-free motors running the tracks and the HyperBrushes.

The 24-volt motors rotate at a speed of 3,000 rpm; therefore, the pair of rolling brushes can scrub surfaces in half the time of competing models. Despite their powerful scrubbing action, the brushes won’t destroy expensive pool surfaces such as pebbles or tile.

This 22-pound Advanced Dolphin is compatible with Maytronics’ new-style power supply, which features sleek touch buttons, an integrated handle and a thin body.

From the power supply, you can set an automated schedule for the week or start a cycle on demand.

Dolphin Cayman

The Dolphin Cayman is a lightweight, compact-sized dream that’s meant for in-ground pools but still safe enough for above-ground swimming pools.

When dry, the robotic pool cleaner only weighs 13.8 pounds. Its light weight and small size along with the way it quickly releases trapped water makes it easy for anyone to manage. The robot is an energy-saver too thanks to twin 24-volt direct-current motors.

Dolphin Cayman

Power supplies are usually boxy, but this isn’t the case with the Cayman’s. It works with Maytronics’ slimmer, lighter power supplies that have touch buttons as opposed to digital ones.

Via the power supply, you can start a 2-hour cleaning cycle. You may also automate the robot’s cycles by setting it to run every day, every other day or every third day.

Since the Cayman is one of the smaller Dolphin Performance models, the filter basket is also proportionally small.

The compact and versatile Dolphin Cayman is perfect for all pool surface types

However, the fine-debris basket is smartly designed as it has a tote handle and loads from the top, not the bottom. The filters click securely into place and easily snap off when you need to clean them.

While the vinyl-safe speedy HyperBrush removes algae and dirt, the HyperGrip tracks help the robot keep its footing on floors and walls. The use of PowerStream technology prevents slippage, and the SmartNav 2.0 software scans for obstacles and maps the most efficient route.

A 50-foot cable equipped with an anti-tangle algorithm means the Cayman can reach the entirety of a 40-foot pool without the cable looping itself.

Noticeable Features

  • Powerful Scrubbing HyperBrush
  • SmartNav 2.0 Robotic Scanning
  • Ultra-Efficient 24-volt DC Motors
  • SnapLoc Top Access Filtration

Dolphin Escape

Built for use in above-ground swimming pools, the Dolphin Escape is an all-surface friendly robot. This feature even extends to fiberglass and vinyl.

Due to being an above-ground cleaner, the Escape only cleans pool floors. However, you can still use it to clean an in-ground swimming pool if you wish.

Dolphin Escape

On the robotic pool cleaner, there is a 45-foot-long cable that gives enough slack to manage a 30-foot swimming pool. The robot is incredibly light, weighing a mere 14 pounds when it’s dry.

Of course, the wet weight is heavier, but the protruding grab handle and the fast rate of water discharge make it manageable to pull out of the pool.

No bags equal no headaches. Instead of messy disposable bags, the Escape comes with a filtration basket that holds fine debris. The filter basket boasts a large capacity, and you can instantly access it by opening the top-placed hatch.

You’ll appreciate the fast-moving Active rolling brush on the Dolphin Escape. Its powerful motion means it can cut through a thick layer of buildup.

The suction rate is just as impressive, filtering 4,000 gallons of water every hour. All this power originates from not one but two 24-volt DC motors.

The Dolphin Escape Above Ground Robotic Pool Cleaner scrubs your pool’s floor and filters out debris so your pool is sparkling clean and ready for fun

Each move the Escape takes is intelligent. The robotic pool cleaner has a set of HyperGrip tracks that provide amazing traction to the floor. CleverClean and SmartNav 2.0 allow it to scan and dodge obstacles while staying on course.

The lightweight power supply’s touch button lets you start and stop a 2-hour cycle with just one push.

Dolphin DX4S

Arguably one of the smartest Dolphin in-ground pool cleaners, the DX4S is a fast learner.

CleverClean with IntelliScan technology calculates and scans the surface of your pool to find the most efficient routing plan. Once the robot sets out on its course, the Advanced DX4S’ dual-brush system spins hard and fast to loosen stubborn particles.

Dolphin DX4S

To enhance its efficiency, the DX4S uses an impeller that helps the robot move at a quick pace along the waterline and even at depths as low as 16 feet. Tracks protected by heavy-duty plastic housing allow the 22-pound robotic pool cleaner to maintain its grip on floors and walls.

Like many of Maytronics’ Dolphin robots, the DX4S’s 60-foot cable swivels, so you won’t have to take time out of your day to untangle it.

While you can’t access the filters from the top of the robotic cleaner, the release tabs make it a little easier to reach them compared to other bottom-loaders.

The ultra-fine and fine-particle mesh filters attach to sturdy frames, and they are simple to disconnect. An indicator on the robot alerts you when the filters are too dirty to work effectively and are in need of a rinse.

In a standard 2.5-hour cleaning cycle, the DX4S filters over 10,000 gallons of water, making your pool water crystal clear.

However, you can order a remote control if you want to use the 1-hour-long quick mode, which is great for light cleanup. Otherwise, you can start the robot and set a weekly schedule from the 180-watt power supply.

Noticeable Features

  • Analyzes your pool surface to make cleaning as efficient as possible
  • 2.5 hour cleaning cycle
  • Swivel cable reduces knots, kinks, and tangles
  • Weekly timer scheduler

Dolphin C-Series

Maytronics’ C3 is a commercial-use robotic pool cleaner from the Dolphin’s C-Series line. The C3 robot’s filtration system consists of a 90-micron fine-particle cartridge and a 50-micron ultra-fine cartridge.

Both filters load from the top of the C3 once you push the ergonomic handle out of the way, giving you instant access. An LED indicator illuminates when the filters need to be rinsed.

Dolphin C-Series

While the sizeable pop-out filters generate a water flow of 4,500 gallons per hour, the quad-brush system loosens and lifts debris. Their exceptional scrubbing power never falls short whether the C3 is catching leaves along the waterline, sand on the bottom or algae on the walls.

The recessed tracks remain protected from becoming lodged with debris, making the robot more durable than open-track models.

To plan where it will go, the Dolphin C3 uses CleverClean technology that scans the swimming pool and tells the robot cleaner to avoid obstacles. The gyroscope turns the C3 in a 360-degree rotation, making the robot cleaner a great choice for curved and angled pools alike.

With a swiveling mechanism keeping tangles at bay, the 60-foot cable provides enough length for most public and apartment pools.

On the power supply, there aren’t many controls. If you want to use all of the robot’s functions, you’ll need a remote.

The remote lets you select either the 2.5-hour standard mode or the 1-hour quick mode. You can even set the C3 to hold off on starting a cleaning cycle temporarily.

Dolphin C-Series Robotic Pool Cleaner

Dolphin H-Series

No matter the shape of the swimming pool, the Dolphin H50 can clean every inch of the cove and every square foot of solid surface even in waters as deep as 16 feet.

CleverClean technology sends the robot on a logical route and helps it detect objects in its path.

Dolphin H-Series

Dynamic Dual Drive allows it to rotate 360 degrees in all directions to reach any areas that need attention. The H-Series robot is also equipped with Maytronics’ ingenious rotating cuff that swivels the cable to prevent knots from forming.

To rid your pool of algae, pollen and debris, the Dolphin H50 has a quad-brush setup.

These two double brushes are combined with white foam rings and PVC bristles, making them appropriate for all surface materials. They are flanked by strong tracks that keep the Dolphin H50 from slipping when cleaning the floor, walls and waterline.

Maytronics opted for a bottom-loading bag instead of cartridge or basket. The cloth bag is reusable – simply detach, dump and rinse. Its 70-micron allergen rating makes it more efficient than the 90-micron fine-particle cartridges.

The filter bag’s extra-large capacity means it can handle a heavy influx of debris that’s bound to occur with the robot’s 75 gpm suction rate.

In 3 hours, the Dolphin H50 can clean the expanse of a 50-foot swimming pool. The 180-watt power supply has a digital readout that’s user-friendly.

If you purchase a separate remote, you can manually drive and spot clean. For enhanced hydrodynamic drag, you can tilt and lock the easy-to-grip handle.

Dolphin Robotic Pool Cleaner Caddy Review

Do you absolutely need a caddy for your robotic pool cleaner? No, a caddy is not a requirement.

Are you gonna want one about 2 weeks into robot ownership? You bet! A pool cleaner caddy will help you stay organized and keep your robot and power box off the ground.

Dolphin Robotic Pool Cleaner Caddy

Remember, pool robots are heavier when wet. A caddy will end the days of lugging the power supply and the robotic cleaner while the cable drags behind you, preventing back strain and cable damage.

One of the best features on the Dolphin caddy is the ability to connect and disconnect the robot from the power supply without removing the power box from its dedicated compartment on the caddy.

This particular robotic pool cleaner caddy is compatible with most residential in-ground and above-ground models. It even works with some commercial models too, including the ones we’ve reviewed in this guide.

It’s a genuine OEM part straight from Maytronics and not shoddily made by some random third-party manufacturer.

A comfort grip on the cart-style handle won’t leave your hands blistered and sore. The durable, lightweight frame won’t rust or corrode from water, so you don’t need to wait until the robot is dry to attach it.

The oversized wheels produce a smooth rolling motion on many surfaces. Plus, there is a place to wrap the cable, so you won’t have to untangle a jumbled mess at the opening of pool season.

You will need a screwdriver to put the robot together. At most, assembly takes about 20 minutes.

Dolphin Power Supply Review

Maytronics provides a power supply box with every Dolphin robotic pool cleaner. Why do you need one if you’re already getting a power supply with your robot?

Power supply boxes tend to wear out faster than their robot mates due to lightning strikes and power surges.

Dolphin Power Supply

Despite your best efforts, accidents do happen, like leaving it out in the rain. Heavy rainfall can wipe out a power supply. While the box is made of heavy-duty plastic, it’s only rated for splashes of water on the Ingress Protection scale.

Plus, having an extra on hand even when the original is working will eliminate pool downtime.

This power supply box works with a variety of Dolphin robots, including the Nautilus CC Plus and the H50. It’s a certified OEM part from Maytronics, and it’s an energy-saver at only 180 watts. The power supply is equipped with an integrated heat sink.

As opposed to heavy copper, Maytronics chose to use a lightweight aluminum heat sink. Aluminum also radiates more heat into the air because it’s less dense than copper.

Thanks to its 5-pound weight and contoured handle, the power supply is easy to lift. The controls are also a breeze to navigate. On the box, there are two soft-touch buttons – one for the power and the other for the scheduling function.

Press the scheduling button to toggle between a 3-times, 4-times and 7-times-per-week schedule. An LED indicator dot light confirms your chosen schedule.

Important note: If your old power supply is broken, set the cord and bracket aside before tossing it. Maytronics no longer includes these parts with replacement power supply boxes.

FAQs

What Kind of Filters Do Dolphin Pool Cleaners Have?

Maytronics opted for rinsable media in all its Dolphin models. Most load from the top, but some are bottom-loading You have the choice between using a fine-debris or an ultra-fine debris filter, and you can interchange them.

Commercial Dolphins, as well as some residential models, offer both levels of filtration in one unit. A debris bag is optional on some Dolphins.

Are Dolphin Robotic Pool Cleaners Hard to Use?

Not at all. Dolphin robots are mostly plug-and-play, and some are controllable via a smartphone app and a remote. Maytronics chose to put a turning mechanism on the cable junction or incorporate anti-tangling software on most models, so the cable can swivel.

This means the chances of the cable tangling are slim to none. Plus, the housing is designed to expel water the moment you pull the robot from the swimming pool, making the robot cleaner lightweight enough for anyone to handle.

What Is PowerStream Mobility?

While the Dolphins’ strong tracks provide an outstanding grip on pool floors and walls, PowerStream mobility takes it a step further. Utilizing streams of water in varying directions, the robots are able to achieve a better grip during vertical climbs.

What Is CleverClean Technology?

Some robotic pool cleaners are smarter than others. Maytronics integrated CleverClean Technology into every Dolphin cleaner for navigation enhancement.

With CleverClean, the robots move purposefully, scanning the swimming pool for obstacles and planning a route to circumvent those obstacles. The end result is the most coverage in the least amount of time.

What Is Active Brushing?

As you probably know, the rolling brushes on a robotic pool cleaner remove algae and scum buildup. Dolphin robots use a technology called Active Brushing to make this task more efficient.

This technology rotates the brushes faster than the rotational rate of other models’ brushes, helping the Dolphins clean faster.

How Long Will It Take One to Clean My Pool?

Three hours is the average cleaning time. However, the working time required to clean your pool depends on the swimming pool’s size and debris volume.

Every Maytronics’ Dolphin robot cleaners are equipped with all or a combination of Active Brushing, CleverClean Technology and PowerStream Mobility, all of which make the robots clean quickly and efficiently (see the following three FAQs for more info).

Are Dolphin Pool Cleaners Energy-Efficient?

Compared to pressure-side and suction pool cleaners, Dolphin robotic cleaners are far more energy-efficient because they don’t need a booster or a pump for power.

In an average month, the increase in your electricity bill will be negligible. We’re talking about only 5 bucks a month.

Do Dolphin Robots Work in Saltwater Pools?

You can use a Dolphin robot in a saltwater-based or a chlorine-based swimming pool. If you have a saltwater pool, these robots can tolerate a maximum salt level of 5,000 parts per million.

Are Dolphin Pool Cleaners Durable?

Definitely! Maytronics builds its Dolphin robotic pool cleaners to last for years. Most people get 5 to 7 years of useful, headache-free life from their robot. With proper maintenance, a Dolphin can last twice as long.

Most Dolphins are warrantied for 2 or 3 years, and their warranty coverage includes parts and labor.

What’s the Difference Between Residential and Commercial Units?

Commercial robotic pool cleaners are designed to cater to the demands of expansive and heavily used swimming pools. Their cables are longer than those on residential versions, and they’re usually able to climb higher.

The filtration system on a commercial robot can handle a lot of debris, and the navigation system makes tight, on-a-dime turns.

What’s the Difference Between In-Ground and Above-Ground Models?

Although there are some in-ground models that are safe to use in above-ground swimming pools, the ones meant for above-ground pools have a few discernible differences. Their brushes are softer to prevent damage to the liner.

Since above-ground pools tend to be smaller and shallower than in-ground pools, above-ground models usually have a shorter cable and smaller filter.

Does Maytronics Only Make In-Ground Pool Cleaners?

Maytronics offers Dolphin robotic cleaners for all types of swimming pools. There are several in-ground Dolphin lines, including the hyper-intelligent Deluxe, the large-pool Advanced and the small-pool Performance.

Maytronics also offers a Performance line for above-ground pools and a few Dolphin ranges for commercial use.
