• Before starting work and storing the device, remove objects such as shards, pebbles, screws or toy parts from the floor.
  Illustration AI

Note

• To avoid striped patterns, test the device on an inconspicuous area before using on sensitive surfaces, e.g. wood or fine stone.
• Do not allow it to remain in one area, but keep it in motion
• Observe the instructions for the floor covering manufacturer.
  Note
  • Work backwards towards the door so that no footprints are generated on the freshly washed floor.

Care and service

Floor head cleaning by means of a rinsing process

ATTENTION

Dirt or detergent residues
The wastewater tank and the hair filters must be cleaned regularly to ensure that dirt does not accumulate in the tank and hair filters.

On completion of work, place the device in the cleaning station and start the rinsing process. Clean the floor head in the cleaning station only by using the automatic rinsing process and not by pouring water into the station separately. Make sure that the wastewater tank is attached. Do not clean the device or the top or bottom of the floor head under running water or under a shower spray; water may enter.

Note: As long as the warning “Tank full” is shown on the LCD, and the wastewater tank has not been emptied, the rinsing process cannot be started.

Note: The LED lighting on the floor head remains switched off during the rinsing process.
