To improve the vacuuming result on tiled
floors the vacuum bar can be turned to an
oblique position of up to 5°.

Loosen the wing nuts.
 Turn the vacuum bar.
 Tighten the wing screws.
If the vacuum result is unsatisfactory the in-
clination of the straight vacuum bar can be
modified.

Adjust the rotary handle to incline the
suction bar.
Parameters for the different cleaning pro-
grammes are preset in the appliance.
Depending on the authorisation of the yel-
low Intelligent Key, individual parameters
can be changed.
The modification of the parameters is only
valid until another cleaning programme is
selected via the programme selection
switch.
If you wish to permanently change the pa-
rameters, you must use a grey Intelligent
Key. This adjustment procedure is de-
scribed in the section "Grey Intelligent
Key“.
Note:
Almost all displayed text regarding param-
eter adjustment is self-explanatory. The
only exception is the parameter FACT:
– Fine Clean: Lower brush speed for re-
moving the grey film on fine stone
floors.

for regular cleaning with reduced noise
level.

machine stops and when there is overload.
 The appliance controls the lowering
and raising of the suction bar automati-
cally, depending on the selected pro-
gramme mode.

vacuum bar in such a way that cleaning is
done at right angles to the joints.
The inclined position and the inclination of
the vacuum bar can be adjusted to achieve
better suction results (see "Setting the Vac-
uum Bar").
