- Lifted 89% of sand from carpet and 88% of pet hair, with nothing tangled, in Vacuum Wars’ tests
- Climbs stacked thresholds up to 3.46 in, so it rarely gets stuck at doorways
- Fits under furniture 3.1 in high with no LiDAR turret
- Dock washes mops in 212°F water and dries them and the dust bag
- Covered only about 1,000 sq ft per charge in Vacuum Wars’ test
- Expensive, and out of stock on Amazon US when checked
- Spinning pads leave edges to a swing-out arm rather than a full-width mop

Alternatives in this type
The E25 plus a dock that turns into a portable carpet and upholstery cleaner. Worth it only if you’ll use that spot cleaner, since the robot itself tested a little worse.
Amazon $629.98Fine for smaller homes with mostly hard floors and carpet that needs a deep clean, but the newer ThermaCharged adds heated washing and better pet hair pickup for less money at Shark.
