What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Spinning mop pads with extend and swing technology clean corners, edges, and under furniture more thoroughly than most rivals
- Base station handles hot-water mop washing, hot-air drying, auto-emptying, and self-cleaning washboard with minimal user intervention
- 12,000 Pa suction delivers strong deep-clean performance on both hard floors and carpets, with automatic carpet-boost mode
Reviewers push back
- Extendable side brush deactivates on carpet and area rugs, leaving edges uncleaned in mixed-flooring homes
- Hot-water mopping improvement over the previous generation is marginal in real-world use, not the step-change advertised
- Base station accumulates grime over time despite its self-cleaning cycle; some manual maintenance is still needed
A highly capable robot vacuum and mop that impresses most reviewers with its cleaning power, advanced base station, and corner-reach features, though one reviewer finds key features fall short in mixed-flooring households.
