Roomba i3 & i3+

One of the latest robotic vacuums that iRobot has released is the Roomba i3/i3+. This Roomba’s price tag doesn’t reflect its real value. It’s also one of the most feature-packed entry-level Roombas. Let’s see what this small machine can do.

iRobot Roomba i3/i3+

Suction Power & Performance

The Roomba i3 comes with a 10x power-lifting suction, making it able to suck up almost any kind of object. It also has a premium 3-stage cleaning, which users can adjust when using it.

Navigation & Mapping Technology

This vacuum comes with smart navigation and a map that will guide the vacuum when cleaning the house. It also has a reactive sensor technology where it should and shouldn’t go.

Connection & Controller

The robot vacuum can clean the house manually or using Wi-Fi. When it is connected to Wi-Fi, users can control the vacuum using app control or voice control.

Roomba i4 (Only CostCo)

The next Roomba robot is the Roomba i4 (4150). Many people say this is almost like the i8+ but a cheaper and more affordable version. Let’s check out the features and performance.

Performance

The Roomba i4 also comes with a 3-stage cleaning system that is premium. However, this machine comes with a 10×2 power making it powerful to pull out stubborn dirt and messes that sometimes you can’t see.

Cleaning Pattern

Supported by its navigation of the house, users won’t need to worry about how the robot vacuum will clean the house. It will not hit or crash into dangerous things as it also has a neat cleaning pattern row.

iRobot Genius

Well, powered with iRobot Genius, this machine can start cleaning just by learning from your habits. It can also suggest extra cleaning when an area in the house is dirty and needs additional cleaning. So, this small machine might even be smarter than your maid.

Roomba E5 (i5 not available yet)

The Roomba E5 seems like an upgraded version of the Roomba 890 but with a more advanced feature. It is also one of the newest models introduced by iRobot, so it is rare to find. So, what are the pros and cons of this version?

Dual Rubber Brushes

Overall, the design of the brushes is almost the same as Roomba i7+. However, the only difference is that Roomba E5 doesn’t have automated suctions. This is a minus part of the machine, as it doesn’t clean the floor as clean as the Roomba i7+.

Design

There isn’t much change in the design. However, the Roomba E5 is quite simple yet elegant. When you see the top part, you will see three buttons: home, clean, and a navigation button.

Virtual Walls

One of the accessories that come with the Roomba E5 is a virtual wall. The primary function of the dual-mode wall is to create invisible linear and radial lines. This will help prevent the Roomba from falling off a particular area of the house.

Scheduling

Like most robots on the market, the i5 comes with a pretty standard programmable scheduler that lets you decide when and where to clean. However, with Adaptive Cleaning technology, the i5 can create its cleaning schedules based on historical data showing how often you run the robot, for how long, and where. You’ll find this feature in all of the i-series robots.

Roomba i6+ (only Amazon)

Upgrade the basic robot vacuum by getting a smarter and more advanced machine with the Roomba i6+. Despite the high price, what can the robot vacuum do?

Cleaning Performance

The Roomba i6+ is a great machine that can clean across a variety of surfaces. It has been proven that the vacuum can clean on shaggy carpets, hardwood, or tile floors. The results were quite impressive as it was clean from all kinds of dirt.

Cleaning Modes

One of the reasons why it can give a great result is because it offers different cleaning modes. One of the modes it offers is the corner and automatic. There is also a mode called shadow that can clean places like under the bed or furniture.

Included Parts

The Roomba i6+ will come with a washable microfiber pad on the bottom part of the vacuum. With this pad, it enables the vacuum to clean on both hardwood and tile.
It will also come with a dust bin that is quite big, making it last for days, even weeks, without having to empty. So, for those with big houses and rooms, this is undoubtedly a great option.

Roomba i7 & i7+

Another great yet expensive option from iRobot is the i7 and i7+. Even though both offer almost the same features, they are offered at different prices. Here are some things you might want to know before buying them.

Self-Emptying Dust Bin

One of the great things about both the Roomba version is that is can self-empty its bin. It also has a slightly larger bin and capacity compared to the other versions. Therefore, even though it can empty itself, it won’t need to do it often.

Free from Animal Hairs

While most vacuum cleaners get tangled up with dog hairs in the machine or the bin, this will not happen to Roomba i7 or i7+. This is because the machine will head back to the dock and throw out any materials that are the potential to cause problems. Then, it will come back and start where it left off.

Wicked Smart Navigation

One of the most wicked features on the Roomba i7 and i7+ is the navigation features. With this feature, users can tell it to go to a specific room. And you can pick as many rooms as you want for the house.

Roomba i8+ (Only CostCo)

The last version that is recommended to try is the Roomba i8. Just like the version before, the Roomba i8+ is pretty pricey. However, it also comes with advanced technology that will help your home task. What are they, and what can it do?

Mapping Sensors

Just like the i7+, the Roomba i8+ comes with smart navigation that can clean almost anywhere in the house. Other than just going to specific rooms, the vacuum is also supported by a camera. Therefore, users can see what kinds of dirt and dust that the vacuum is cleaning.

Battery Life

One of the great things about the Roomba i8+ is the battery capacity, 2210 mAh. It can clean up to 90 minutes non-stop before wandering back to its station. However, the con is it takes around 120 minutes to recharge it before going back to its task.

Sensors

As an expensive machine, the Roomba i8+ is supported with high advanced sensors that will help prevent the machine from crashing or hitting things. It will automatically detect an object and prevent it from going to the object.

Which is Best to Choose & Buy?

If you need a robot vacuum that can help clean your house with excellent results, then the Roomba i7 or i7+ is one of the best options, especially if you have a big house. However, the cost is a bit expensive for a robot vacuum.

On the other hand, for those who are looking for something cheaper but needs full features should choose the Roomba i3. This is one of the most affordable yet most feature-packed robot vacuums in the Roomba lineup.

  1. I still don’t have a clue about the main differences among these models. You just highlighted certain features without identifying the exclusive ones. Why not a feature comparison table?
