What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Hot water mop-pad washing removes stains effectively and reduces manual cleaning
- Auto-lift mopping clears carpets without wetting them, allowing one-pass cleaning of mixed floors
- Obstacle avoidance using structured light and laser outperforms camera-based systems
Reviewers push back
- App occasionally freezes and requires restart
- Auto-lift mop pads can dislodge when removed, raising questions about long-term reliability
- Omni station is bulky and heavy compared to simpler docking bases
“it had the highest score we've seen so far and 11 out of a possible 12”
Reviewers praise
- Cleans carpets thoroughly, matching or exceeding higher-end Roombas in deep-cleaning tests
- Self-emptying base holds weeks of debris and works reliably
- Dual rubber brush rollers resist hair tangles better than most competing designs
Reviewers push back
- Cannot create no-go zones in the app, requiring physical barrier accessories
- Poor obstacle avoidance—bumps into objects unless they trigger its contact bumper
- Mapping takes multiple cleaning cycles to stabilize and remains less precise than camera systems
Reviewers agree the i3 EVO cleans carpets well and empties itself reliably, but its floor-tracking navigation lacks the room-boundary controls and obstacle avoidance found in camera-based models.
