What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Strong suction and good pickup on carpets, sand, and pet hair
- Effective mopping with hot water washing and hot air drying at the base
- Setup and app mapping are quick and straightforward
Reviewers push back
- Obstacle avoidance is inconsistent and often weak, especially around cords and pet waste
- Hair can tangle at the ends of the roller brush
- Feature sets shift confusingly between variants and generations, with some models dropping sensors, solution tanks, or mop-pad detachment
This line cleans hard floors and carpets well and automates its own upkeep, but obstacle avoidance and feature consistency vary sharply between versions and generations.
Vacuum Wars found one variant's obstacle avoidance excellent while two others scored among the worst on record; Vacuum Chef found the newer generation's obstacle avoidance well below average overall
