Roborock S4 Max

The Roborock S4 Max comes with all of the bells and whistles you’d expect from a high-end robot, including mapping technology, high-tech sensors, and comprehensive remote controlling options. This is a must-have for homeowners who are looking for a top-performing robot without mopping capabilities.

Roborock S4 vs. S5 vs. S6 vs. S7 vs. S8
Roborock S4 Max

2000-Pa Suction with Carpet Detection

The first thing you’ll want to note about the Roborock S4 Max is that it can deliver a whopping 2000 Pa of suction power. This is more than enough power to remove more than just surface debris on medium-pile carpeting. Best of all, this model comes with Carpet Detection Technology, which automatically cranks the suction power to the max when it treads on carpets.

What this means is that you don’t have to fidget with the controls (more on this in a bit) to produce the best clean on smooth and carpeted surfaces. However, the longer it activates max power, the quicker it drains its battery (more on this in a bit, too).

Comprehensive App Control

Let’s talk about how you can control your S4 Max. All you need is a stable internet connection and Roborock app on your smartphone. After syncing your phone to the robot (done in less than a minute), you’ll gain access to all of its programmable features straight from your phone.

Because the S4 Max comes with mapping technology, you can open digital layouts of your home to define no-go zones, obstacles, and select specific rooms to clean. The app also lets you see which parts of your home the robot has already cleaned. There are also status reports in the form of push notifications to tell you what’s going on with your S4 and how much cleaning it has left.

Alexa Support

If you don’t feel like picking up your smartphone and sending commands to your S4 Max, you can sync it to your Alexa device and send voice prompts to the robot. It only receives basic commands through Alexa like start, stop, recharge, and basic scheduling options. If you want to access the more advanced programmable features, you’ll have to use the smartphone app.

Advanced Cleaning Scheduler

One thing that users rave about is the S4 Max’s advanced cleaning scheduler. Unlike other robots where you can just create cleaning schedules for your entire home, the Roborock app lets you control which rooms to clean and at what times.

Some people use this feature to keep the S4 Max out of their home offices at specific times so as to not disrupt their work. We can definitely see why this unique feature is a real game-changer.

3-Hour Runtime + Recharge and Resume

The S4 Max is built with a massive battery that provides enough power to clean for 3 hours nonstop or about 1,100 square feet per charge. When its battery reaches 10% or less, it’ll make a beeline to its docking station to recharge.

At 80%, it’ll dismount from the charger and pick up where it left off. While not a unique feature by any means, the convenience of not having to babysit your robot and send start/stop commands is a must-have for busy folks.

Roborock S5 MAX

Like the S4 Max, the S5 Max offers a wide range of premium convenience-adding features combined with maximum suction and cleaning power. However, this unit comes with a mopping module that can leave smooth floors squeaky-clean after just a couple of passes.

Roborock S5 MAX
Roborock S5 MAX

2000-Pa Suction + Floating Brush

The Roborock S5 MAX offers the same amount of suction power—2000 Pa—to eliminate surface and embedded debris residing in carpet fibers. It also comes with Carpet Boost Technology that kicks the robot’s suction into high gear in the presence of carpeting, and it comes with a similar floating-style brush that maintains constant contact with whatever surface it’s cleaning.

In terms of carpet-cleaning performance, if you keep the S5 MAX running at full power, you can expect excellent cleaning results in fewer passes.


Hybrid Vacuum and Mop Robot

One thing that sets the S5 MAX apart from countless other robots on the market is its mopping capabilities. By attaching the mopping module—e.g., the water tank and microfiber brush—this robot can vacuum and mop smooth floors to remove hidden specks of dust and minor spills. However, “mopping” is used generously in this sense as it simply wipes floors with a moistened cloth rather than actively scrubbing away stains and spills.

LIDAR Mapping and Navigation

If you’re not familiar with robotic vacuum cleaners, you should know that LIDAR is the latest and greatest form of navigation technology. An array of sensors constantly detects the S5 MAX’s surroundings to create digital layouts that you can access via your smartphone. LIDAR and SLAM also give the S5 MAX its near-perfect sense of navigation. Obstacles, cliffs, and

Saves 4 Maps

One impressive feature of the Roborock S5 MAX is its map-storage capabilities. Instead of storing just one or two floors, this Roborock can save up to four floors. As it runs around your home, it’ll automatically measure the dimensions of every room, identify the locations of obstacles, and even figure out which parts of your home are covered in carpeting. The latter is a handy feature that works well with creating no-mopping zones. Speaking of which…

No-Mopping Zones

Similar to the S4 Max, users have full control over the S5 MAX via the Roborock smartphone app. The app lets you create no-go zones, select specific rooms to vacuum and mop, as well as define no-mopping zones. Since this robot can mop and vacuum simultaneously, users will want to make sure the S5 MAX doesn’t accidentally mop carpets, which you can do with a few swipes of your finger on your smartphone’s screen.

180-Minute Runtime

The S5 MAX is designed to run for 3 hours nonstop on its lowest (quietest) mode, which is pretty much just for surface debris removal. The max runtime drops to about half when running Max Clean mode since it needs to both provide maximum suction and moisten the microfiber cloth. Thankfully, it has auto-recharge (or manual recharge via the smartphone app or Alexa) and auto-resume to pick up where it stopped prior to charging.

Roborock S6

The Roborock S6 hybrid vacuum and mop bot is one of the more premium-grade robots in the Roborock lineup. The robot places a greater emphasis on cleaning efficiency, but it doesn’t miss out on thoroughness either.

Roborock S6
Roborock S6

Adaptive Routing

One of the ways the S6 maximizes cleaning efficiency is with the help of Adaptive Routing. Its sensors are constantly on the lookout for newly made stains and spills. If it finds something that wasn’t there in its initial pass, it’ll backtrack and clean up the mess before continuing on with its pre-routed cycle. Even though it will take longer for the S6 to clean every square inch of your home if it needs to reverse and clean, it ultimately saves time by not having to commence a full cleaning cycle to clean up tiny messes.

Multi-Floor Mapping

The Roborock S6 comes with enough storage space to save multiple floor layouts. When moving it up and down floors, it takes just a few seconds to recognize its new surroundings and to access the correct map, which also helps save battery life and extend its runtime per charge.

67-dBA Noise Output

Most modern robotic vacuum cleaners are on the quiet side, but the S6 takes it to a whole new level. Generating just 67 dBA of noise (lowest setting), it won’t drown out conversations and has less of a chance of waking up sleeping pets and babies. Of course, if you don’t want it to roam into the nursery, just use the Roborock app and set up a no-go zone for that room.

Roborock S6 Pure

At first glance, the Roborock S6 and S6 Pure look completely identical, but there are a few additional features that make the latter robot easier to use.

Roborock S6 Pure
Roborock S6 Pure

Spot Clean Button

The S6 only has two buttons on it: Power/Clean and Home. As for the S6 Pure, you get an additional Spot Clean button that lets you scroll between different tiny-area cleaning modes. In all honesty, you’ll hardly ever depress the buttons on your robot since most of the time, you’ll send instructions and program the robot’s features via the downloadable Roborock smartphone app or by having an Alexa device relay your commands.

180-mL Water Tank

Both the S6 and S6 Pure are hybrid vacuum and mop robots, but the S6 Pure has a slightly larger water reservoir of 180 mL (compared to the S6’s 148-mL tank). The additional water storage capacity gives you more flexible controls over the water flow rate as well as lets the robot vacuum and mop a wider area between refills.

11 LIDAR Sensors

So, what does the Roborock S6 Pure sacrifice in exchange for a larger water tank? The number of sensors. The S6 has 14 sensors situated all around the robot, whereas the S6 Pure “only” has 11. While there’s not a noticeable difference between the missing three sensors, one could argue that the S6 has marginally better sensor and mapping capabilities.

Soft-Bristle Brushes

One feature that both robots share is soft-bristle brushes with about 250% more bristles than other Roborock models. The softness of the brush bristles helps remove surface debris more easily while, according to some users, might struggle at removing embedded debris from carpets like pet hair.

Roborock S6 MaxV

The third S6 that we’re looking at is the S6 MaxV, the strongest, most intelligent variant. With 25% more suction power and dual cameras, this high-end vacuum robot cleans much quicker and with fewer errors.

Roborock S6 MaxV
Roborock S6 MaxV

2500-Pa Suction

The S6 MaxV delivers up to 2500 Pa of suction when Max Cleaning Mode and Carpet Boost are activated. Compared to other Roborocks, the extra 500 Pa means a deeper clean on thicker area rugs and carpets, as well as the enhanced ability to suction tiny dust specks and pet hair from between tiles and floorboards. On its lowest setting, you can hope to get about 180 minutes of nonstop cleaning from your S6 MaxV.

Reactive AI

It’s also worth noting that the S6 MaxV has the ability to react to newly formed stains and spills on the fly. If it detects new messes during its cleaning cycle, it’ll go out of its way to remove them before commencing with its programmed travel route. Again, this can make each cleaning cycle last a bit longer, but it ultimately reduces the number of cycles it needs to clean an entire home per day.

Dual Camera + Remote Viewing

One handy feature that we wish was in more modern robotic vacuum cleaners is Dual Cameras. The first camera scans rooms and creates a digital layout that you can access via the Roborock smartphone app to create no-go zones, no-mopping zones, and choose rooms to clean. The second camera is used to give the owner remote viewing of what the robot is up to. By opening the app on your phone, you can see what the robot sees. The second camera also helps with identifying obstacles to make its cleaning route even more efficient than ever.

Roborock S7

The higher the Roborock model number goes up, the more premium features it comes with. The Roborock S7 is one of the most impressive high-end, newly-released robotic vacuum cleaners that offers more power than most, enhanced mopping capabilities, and while generating much less noise.

Roborock S7
Roborock S7

2500-Pa Suction Power

You can never have too much suction when it comes to robotic vacuums, and the Roborock S7 aims to provide users with the best cleaning performance imaginable. With 2500 Pa of suction power, this Roborock is able to clean more than just surface debris from carpets, area rugs, and smooth floors. The intense suction power combined with carpet recognition ensures that the robot never misses a dirt pile as it moves from room to room.

Multi-Directional Floating Brush

Instead of using a main bristled brush, the S7 is fitted with a rubber brush that draws in more air and debris with each swipe. Best of all, it’s a floating brush that moves more than just up and down. This gives the brush the ability to maintain constant contact with nearly all surfaces, including shaggy area rugs, medium-pile carpets, laminate, tile, and floorboards.

Roborock S7 Review

Ultrasonic Mopping Technology

But the mopping module is where the S7 blows most of its hybrid robot competitors out of the water. Instead of simply wiping floors with a moistened pad, the S7’s pad oscillated with the power of ultrasonic technology, which helps it remove old spills and pet leavings. This means the pad will become dirtier and wear down more quickly over time, but it also ensures better mopping performance.

Carpet Recognition

As mentioned earlier, the S7 has carpet recognition technology that automatically kicks suction power into high gear as soon as it steps foot on carpeted surfaces, but it does more than that. When it detects carpets, it will automatically lift the mopping pad to prevent leaving moist spots and prevent wear and tear on the pad’s soft fibers.

Noise-Dampening Design

The S7 was designed with low-noise output in mind. Inside of the Roborock S7 are several noise-dampening components that bring suction and vibration noises to a minimum, ensuring a bother-free work environment at home. While it’s not whisper-quiet by any means, at just 67 dBA, it’s not much louder than normal conversation tones.

Auto-Emptying Dock (Soon to be released)

Something that you might have realized about all of the Roborocks on this list thus far is that none of them come with a self-emptying dock. For the most part, you shouldn’t have much trouble emptying out their large dust bins once or twice a day, but for the busiest folks out there, you’ll be happy to learn that the S7 is compatible with an auto-emptying charging dock. As of right now, the auto-emptying dock is not yet available, and as far as we’re concerned, you might have to purchase it separately when it does come out.

Roborock S7 Robot Vacuum
Roborock S7

Top-Loaded Filter

One feature that most people won’t care to point out is that the S7’s filter is at the top of the dust bin instead of on the side or below. This makes it clog much less frequently while also making it easier to empty out.

Roborock S8

Roborock’s S8 is currently in the works, but not much news is available of this model yet. We can expect it to have at least 2500 Pa of suction power and ultrasonic mopping technology, and it would be nice if it came standard with an auto-emptying dock. However, until Roborock makes an official announcement regarding its specs, features, and release date, we can only sit back and wait.

Don’t Sleep on Roborocks!

It’s pretty clear that Roborock robotic vacuum cleaners are a force to be reckoned with. Today, we discussed seven different models, from the S4 all the way up to the upcoming S8. Hopefully, you’ll have a good idea of what each Roborock model has to offer!
