Cleaning the rollers
ATTENTION
The rollers should be washed under a tap or cleaned in
a washing machine after each use to prevent accumu-
lation of detergent residues in the rollers that can lead
to the formation of foam over time.
The fresh water tank and waste water tank must be
emptied if the device is laid on the floor in order to re-
move the rollers. This prevents liquids from escaping
from the tanks while the device is lying on the floor.

do so.

or
 Wash the cleaning rollers in the washing machine
up to 60°C.
ATTENTION
Do not use any soft detergents when cleaning in the
washing machine. This avoids causing damage to the
microfibres. It also preserves the high performance lev-
els of the cleaning rollers.
The cleaning rollers are not suitable for the tumble dry-
er.
Figure to
 Once cleaned, place the rollers on the cleaning sta-
tion storage and leave them to air dry.
 Drying time can be minimized by wringing out the
rollers beforehand.
 Also clean the floor head cover and waste water
tank if the device is not going to be used further.
 Clean the roller drive with a moist cloth.
Detergents and care products
ATTENTION
The use of unsuitable cleaning and disinfecting agents
can damage the appliance and will void the warranty.
Note
Add cleaning or disinfecting agent as required.
 When dosing the detergent and care product, fol-
low the manufacturer's dosage instructions.
 To prevent foaming, first fill the fresh water tank
with water then cleaning or disinfecting agent.
 To avoid exceeding the "MAX" fill level on the fresh
water tank, leave room for the cleaning or disinfect-
ing agent when filling with water.
