Prepare the automatic scrubber as described in Chapter "Tasks before starting cleaning".
Lower the squeegee and brush unit on site.
First switch on the squeegee, then the brush unit and regulate the cleaning solution
(see Secs. "Squeegee On/Off", "Brush unit On/Off", "Regulating the cleaning solution").
Guide the automatic scrubber carefully over the area to be cleaned at slow walking speed. Pay attention to the
following:
•
Move the appliance cautiously taking care to avoid other people and objects in the vicinity.
•
Never put other people at risk when working with the appliance.
•
When cleaning floors with the appliance, never go over thresholds, steps or carpets or objects
which could get caught, such as e.g. cables. Max. floor gradient 2%.
•
Never leave the scrubber unattended. Keep unauthorized persons away from the appliance.
•
If faults arise – e.g. the noise from the suction or brush units gets louder or the suction force of
the squeegee drops – stop the scrubber immediately and switch it off (see Sec. "Automatic
scrubber stop/switch-off"). Follow the procedure described in Chapter "Troubleshooting".
•
Do not run over the mains cable. There is a risk of fatal injury if you run over the mains cable
with the cleaning tool rotating.
To stop cleaning, switch off the brush unit (see Sec. "Brush unit On/Off") and push the automatic scrubber
forwards with the squeegee still switched on, in order to suck up any cleaning solution still on the floor.
Stop the appliance and switch it off (see Sec. "Automatic scrubber stop/switch-off").
