Operation

General notes on operation

ATTENTION
Moisture
Material damage to sensitive floors Check the surface to be cleaned for water sensitivity at an inconspicuous location before using the device.
Do not clean water-sensitive floor coverings such as e.g. untreated cork floors, since the moisture can penetrate and damage the floor.

ATTENTION
Material damage
Damage to the device from pointed, large and/or bulky objects.
The device must not be stored and used on hard coarse dirt and objects, as the parts can get stuck under the waste water tank and cause scratches on the floor and tank.
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.
Illustration AJ

• Floor cleaning is performed using a to and FRO movement at the same speed as when vacuuming.

• Activate the Boost function for heavy soiling. Hold the Boost function button pressed for this. The roller speed and water volume are increased when the boost function is activated. The Boost function can be activated at cleaning level 1 and cleaning level 2.
  The indicator for the corresponding cleaning level  flashes when the Boost function is activated. Allow the device to slide slowly over the floor without exerting any pressure on the device.
  Illustration K
  

• Various different rollers are available, depending on the scope of delivery. The colour of the rollers indicates the respective special application for which they are suitable.
