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.

The i4 is the same robot vacuum as the i3. Both models don’t not offer a wholly unique or distinctive vacuuming experience.

Roomba i5/E5

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.

Roomba E5 vs i7
The Roomba E5 uses iAdapt 2.0 and sensor-based navigation where the Roomba i7 uses camera-based navigation using iAdapt 3.0.

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 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.

Roomba i7+ vs S9+
The Roomba i7+ has more features than any Roomba prior, but is slightly beat by the Roomba s9+.
