Critics & buyers
The human jury in one chapter — what the video reviewers score and say, the reviews behind it, and how Google buyers rate them.
What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Vacuums effectively on hard floors and carpets with strong suction and dual brush rollers that handle hair and debris well
- Dock automatically washes and dries mop pads with hot air, empties dust bin, and refills water tank with minimal user intervention
- Navigates reliably using laser mapping without getting stuck or losing position during cleaning runs
Reviewers push back
- Mop pads cannot reach wall edges or corners due to their central mounting position
- Obstacle avoidance using camera and structured light is inconsistent and less reliable than higher-end systems, especially with cords
- Spinning mop design spreads sticky messes rather than lifting liquid, requiring multiple passes and manual mop cleaning for tough spills
Reviewers agree the Q Revo delivers strong vacuuming and mopping performance with an impressive multi-function dock at a mid-range price, though its edge-cleaning and obstacle avoidance have clear limitations.
One reviewer found obstacle avoidance surprisingly good after firmware updates while others report it remains weak and unreliable
