iRobot Roomba i3 Evo : Affordable and Efficient Cleaning

iRobot Roomba i3 Evo

When it comes to robot vacuums, the Roomba j7 may be the top choice if you want all the latest features, but the iRobot Roomba i3 Evo offers an excellent balance of affordability and performance. While it lacks AI obstacle avoidance and app-enabled cleaning zones, it’s still a smart choice for those looking for a cost-effective robot vacuum.

Smart Mapping for Targeted Cleaning:

One of the standout features of the iRobot Roomba i3 Evo is its smart mapping capability. With this feature, you can precisely control which rooms the robot cleans and when it cleans them. This means it won’t attempt to clean your entire house during every run, which can be less intrusive and annoying to family members. You’re less likely to find it stuck in a corner after someone manually turns it off.

Similar Power, Longer Lifespan:

In terms of cleaning power, the i3 is almost as powerful as the more advanced j7 model. Plus, it shares the same repairability, which means it should last longer than cheaper robot vacuums from other brands.


  • Excellent build quality.
  • Automatically empties dustbin into large external dirtbag.
  • Easily sucks up rice and cereal.


  • High recurring costs and demanding maintenance needs.
  • Doesn’t clean pet hair very effectively.

Auto-Empty Option:

For a price significantly lower than the j7, you can even get the iRobot Roomba i3 Evo with an auto-empty dock, making maintenance even more convenient. The physical design of the i3 is also similar to the j7, with two multi-surface rubber roller brushes that are excellent at picking up dirt without getting tangled with long hair like bristle brushes often do.


However, it’s worth noting that the i3 may bump into obstacles more frequently than the j7, potentially causing minor disruptions or even toppling delicate items like vases on pedestals. It’s a robust cleaner, though, capable of handling various floor surfaces and transitions with ease.

iRobot Roomba i3 Evo Plus: The Added Convenience of Auto-Emptying:

If you want the convenience of a robot vacuum that can empty its own bin, consider the iRobot Roomba i3 Evo Plus. It comes with the auto-empty bin feature, making it a great value option in the Roomba lineup.

Keep-Out Zones and Accessories:

One limitation of the i3 is the absence of an option to add keep-out zones within the app. If there are specific areas where you don’t want the robot to go, you’ll need to purchase iRobot’s virtual walls, which emit a barrier or circle to keep the robot out. These accessories cost $99 for a pair, so if you require more than a couple of keep-out zones, you might want to consider the j7 model instead.

Aesthetic and Performance:

In terms of design, the i3 boasts an attractive woven plastic gray top, a departure from the typical shiny black plastic found in many robot vacuums. It can still get stuck on common obstacles like charging cables and small objects, so a bit of tidying up is recommended before setting it loose. Fortunately, iRobot’s anti-tangle technology helps the robot navigate around obstacles effectively, though it may not work perfectly with phone charging cords.
