Consensus
our Verdict
Product testers praised the iRobot Roomba i4, recommending it for carpets and bare floors. Reviewers at Mashable hailed its outstanding build quality and excellent battery life, which ran for 100 minutes on a single charge during experiments.
It comes with a replaceable HEPA filter that performed well, sealing allergens during testing. The robot vacuum has a good mapping and navigation system and automatically adjusts settings based on the floor type and level of dirt, although it occasionally gets stuck on obstacles.
If you need a model that maneuvers and navigates better, see our iRobot Roomba 981 review. Product testers at RTINGS were pleased with its 65.3 dBA noise rating during their experiments.
Researchers clocked its suction power to a low 0.03 kPa during testing, but it cleans effectively, removing an impressive 87% of the large debris on bare floors and 76% on low-pile carpets.
However, reviewers bemoaned the high-maintenance design, which requires filter replacement every two months. The 0.3L dust cup also proved on the small side during testing.
