Gets embedded sand out of carpet far better than the typical robot Vacuum Wars ↗

Cons

The dock empties the bin, but you still wash the mop pad yourself Vacuum Wars ↗
Long human hair still tends to collect around the rollers Vacuum Wars ↗
Battery efficiency was only average next to the Q8 Max+ Vacuum Wars ↗

The numbers that matter first, then every fact by group. As published by the maker or the store we read it from.

Robot height3.8 in

Climbs thresholds up to0.8 in

Mop lift on carpet0.2 in

Runtime per charge180 min

Suction power6,000 Pa

Consumables: a 2.5 l dust bag in the station, which lasts up to 49 days.

Suction and brushes 1 fact

Suction power Suction in pascal, as the maker measures it. More pascal helps on carpet, but it says little about how well the robot picks grit off a hard floor.: 6,000 Pa

Mopping 2 facts

Mop type How the mop is built: flat pads, two spinning discs or a roller. Discs press harder on dried-on dirt, a roller rinses itself while it works.: flat or vibrating pad
Mop lift on carpet How far the robot lifts the mop when it drives onto a carpet. From about 0.4 in (10 mm) a medium pile stays dry.: 0.2 in (5 mm)

Dock 4 facts

Empties the dust bin The dock empties the robot’s dust bin, usually after every run. You only empty the dock’s bag or bin.: yes
Bagless The dock collects dust in a bin instead of a disposable bag. No bags to buy, but you empty it yourself.: no
Dust bag capacity How much the dust bag in the dock holds.: 2.5 l
Dust bag lasts How long the maker says a dust bag lasts with daily use. With pets or a lot of carpet it is shorter.: up to 49 days

Navigation and obstacles 3 facts

Navigation How the robot maps your home and follows that map. Lidar measures with a laser and works in the dark, a camera looks along and recognizes more.: LiDAR turret
Obstacle avoidance How the robot sees loose things on the floor, such as cables, socks or a pet accident. A camera with depth sensing sees more than a bumper that reacts on contact.: 3D sensor (structured light)
Climbs thresholds up to The highest threshold the robot takes, as the maker states it. Measure your own: the step into a bathroom or onto a balcony is often higher.: 0.8 in (20 mm)

Robot 2 facts

Robot height How tall the robot is. It decides whether it fits under your sofa, bed or cabinet.: 3.8 in (9.7 cm)
Dust bin in the robot How much dust the robot holds before you empty it. It matters less with a self-emptying dock, which empties the bin after every run.: 350 ml

Battery 1 fact
