What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Strong suction and airflow measured between 16 and 21 CFM outperforms expectations for its class
- Excellent hard floor cleaning with superior crevice pickup that clears debris other robots miss
- Picks up human and pet hair without tangling because it uses a suction nozzle instead of a brush roll
Reviewers push back
- Narrow three-inch suction path struggles with carpet coverage and picks up only 75 percent or less on thick carpet
- Random navigation leaves missed spots especially around obstacles like chair legs and the charging base
- Extremely small dustbin at half a cup requires frequent emptying and uses an awkward screen-removal design
Reviewers agree the V3s Pro excels on hard floors with strong suction but struggles on carpet due to its nozzle-only design and lacks advanced navigation.
One reviewer found it picked up debris decently on low-pile carpet while others emphasize it struggles significantly on any carpet
