Product Snapshot

Overview

The iRobot Roomba i3+ Evo 3550 was announced in 2020 as a mid-tier Robovac with a 0.5-liter dustbin, wireless capabilities for Amazon Alexa and Google Assistant compatibility, and a self-emptying dustbin. Not many of the best vacuum cleaners have this, but the i3+ ships have an external dirt compartment that holds up to 60 days of dirt and debris. Also, unlike many highly-rated robot vacuums, the i3+ can only map out a cleaning area on a single floor and has a 1.5-hour battery life.

Its dual multi-surface rubber brushes are great for dealing with pet hair. The i3+has a max noise output of 74.45dB, has cliff sensors to avoid stairs and ledges, and an edge-sweeping brush to clean around corners. However, its battery life is below average.

Consensus

our Verdict

The Roomba i3+ EVO offers a taste of luxury in the realm of affordable robot vacuums. It features a smart mapping system, but it is limited to one floor. Still, it has a  self-emptying Clean Base, and its cleaning prowess is commendable, with a tested 97.15% pickup rate on hard flooring and a 97.61% pickup on carpet.

This performance places it in the top third on our certified tested list. The Roomba app is user-friendly and is also able to provide personalized cleaning schedules after learning from your cleaning habits. The app can also be integrated with Amazon Alexa or Google Assistant for voice commands.

Battery life is an average of 90 minutes with 2.5 hours of charging time, while its noise output is quite high at around 74.45 dB, making it louder than the average Robovac in our certified tested list. The i3+ EVO is a value-laden choice if you’re looking for convenience. However, its 900 Pa suction power is below average for robot vacuums.

Reason to Buy

  • Excellent cleaning performance
    • The iRobot Roomba i3+ picks up up to 97.15% of debris on bare floors and 97.61% of carpets, earning it a top third ranking on our certified tested list.

  • Large dirt compartment size
    • The dirt back inside the iRobot Roomba i3+’s docking station can hold up to 60 days’ worth of debris. This means owners will only have to empty it a few times a month.

Reason to Avoid

  • Basic navigation system
    • The Rooba i3+ has a basic smart mapping system that allows it to map only one floor at a time, tracing the walls and landmarks in a room. Its mapping is managed through the iRobot Home app. However, it bumps into furniture and other obstacles quite often.

  • Louder than average noise output
    • The iRobot Roomba i3+ has a sound output of 74.45 dB, which makes it louder than 70% of robovacs in our certified tested robovacs.

  • Below-average battery life
    • The Roomba i3+ Evo 3550 has a 90-minute battery life, which places it in the bottom quarter of our list.

The iRobot Roomba i3+ Evo 3550 has a shorter battery life compared to the Roomba i7+, but the i7+\ needs more time to charge. It is also the more expensive alternative, and being a more advanced model, the Roomba i7+’s mapping system allows users to create cleaning zones, block off boundaries, or send the Robovac to a specific spot. The i3+ cannot do that. For another comparable model, see our iRobot Roomba 690 Review.

The iRobot Roomba i3+ Evo 3550 is different from the Shark IQ RV1001AE in that the i3+ has a longer battery life. The i3+ also has a shorter charge time. This makes the i3+ the better pick in both instances, as it has a longer cleaning time. The two also have different methods of sectioning out barriers, as the Shark Robovac uses magnetic boundary markers while the i3+ uses virtual walls. Check out our Lefant M210 robot vacuum cleaner review to compare with another option.

The iRobot Roomba i3+ Evo 3550 is more expensive than the iRobot Roomba i3, and this is because it comes with a self-empty dust bin, while the i3 does not. However, there wouldn’t be any difference in performance if you decided to buy the basic i3 and the self-emptying base station separately. If you’re interested in other models, we’ve also covered the i4 in our iRobot Roomba i4+ EVO review.
