For buyers who want a low-slung flagship that mops with a hot-washed roller and handles tall thresholds. Cheaper robots match its carpet cleaning and run longer per charge.

Pros
- Fits under furniture just 98 mm (3.9 in) high because it has no LiDAR turret
- Climbs double-layer thresholds up to 1.65 in, so it gets into rooms many robots can’t
- Dock washes the roller mop with 140°F water, dries it with hot air and dispenses detergent, so mopping is hands-off
- Optional auto refill and drain kit can plumb it in and remove tank filling altogether
- Left no hair wrapped on the brushes in Vacuum Wars’ tangle test
Cons
- Covered only about 1,090 sq ft per charge in Vacuum Wars’ test, low for a flagship
- Lifted 87% of sand from carpet, behind several cheaper robots
- Expensive at well over $1,000

Independent tests

Narwal Flow
The first Narwal track-mop robot, still a good hard-floor mopper. The Flow 2 does more for similar money.
