Dry mops can reflect an empty tank, incorrect cleaning mode or a poorly seated water module. Confirm the water path before assuming a failed pump.

Start with these checks

  1. Check the selected job actually includes mopping and a permitted water setting.
  2. Fill and seat the relevant clean-water tank according to the manual.
  3. Inspect user-accessible outlets or modules without poking into the pump.

What this looks like at home

A vacuum-only room routine can leave mops dry even when the station tank is full.

Keep clean water, dirty water and dry dust separate

Check What matters
Clean-water side Use the permitted water and solution method.
Dirty-water side Empty and clean the removable tank as directed.
Pads, roller and tray Inspect, clean and dry only as the manual allows.

A mistake to avoid

Do not use a pin or chemical descaler in an outlet unless the manufacturer prescribes it.

Buy a part only after identifying the cause

Check the exact model and part reference before buying. If cleaning resolves the problem, a replacement may be unnecessary.

What the result tells you

Note whether the pad stays completely dry or becomes damp unevenly. Also record whether the robot is taking water from its own tank or relying on a station procedure in that particular model.
