529 of the 557 models we track have this.
When it matters
- Long hair and pet hair, which wrap around a bristle brush.

- no (assumed)
Mopping 6 facts

When it matters
- Homes with a lot of hard floor that you want mopped, not just wiped.

When it matters less
- If you only vacuum, the mop’s build decides nothing.
Source: de.air-robo.com · checked on Oct 10
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.

- Homes with many corners and table legs.
When it matters less
- In open rooms the strip it leaves along the wall is small.

- Automatic mop detach
When it matters
- Homes with carpets or rugs that should stay dry.

- no (assumed)
- Mop refreshed while mopping
When it matters
- Large hard floors, where a mop that is never rinsed spreads dirt around.

- Water tank in the robot
When it matters
