iRobot Roomba 650 Robot Vacuum

The Roomba 671 is for buyers who prioritise brand trust and proven cleaning performance over smart navigation features. It cleans well but not as efficiently as modern LDS robots.

OVERVIEW

iRobot is the brand that invented the robot vacuum category and the Roomba 671 proves that experience counts. The three-stage cleaning system uses a combination of edge-sweeping brush counter-rotating brushes and powerful suction to lift debris from edges corners and surfaces. The Dirt Detect sensor is a clever feature when the robot finds a high-traffic area with concentrated dirt it spends extra time cleaning that spot before moving on. It is Wi-Fi connected so you can start stop and schedule cleaning from the iRobot Home app and voice control works with both Alexa and Google Assistant. The auto-adjust cleaning head adapts to different floor types rising for carpets and lowering for hard floors to maintain consistent contact. Where it falls short is navigation it uses iAdapt 1.0 which is essentially improved random bouncing rather than systematic mapping so it takes longer to cover a room and may miss spots. The NiMH battery is also outdated compared to modern Li-Ion packs. But the cleaning performance is solid and the brand trust factor is significant for many buyers.
