(1)Switch on the recycling water pump at the switch on the
control panel on the arm rest. Hold pressed for at least
2 seconds.
(2)Use the rotary knob on the control panel to set the re-
quired water quantity according to the amount of sweep-

2.4.6 Water circulation system / recycling mode

In the recycling operation, the filled water is circulated in
the waste water tank/waste container.
This is conveyed to the suction mouth via a centrifugal
pump.
This recycling water is immediately sucked into the suction
mouth, cleaned by the side filters and returned to the
waste water tank/waste container via the valve.
Note
The system has a deficiency sensor for indicating a low
level of circulating water. When the limit value is reached,
the pump is switched off (LED in the center console goes
out).
In this case, fresh water can be reintroduced into the circuit
via the water nozzles in the suction mouth.

2.4.7 Sweeping

The operation or the assignment of the control console can
be found in the chapters of the 2-brush sweeping system
or 3-brush sweeping system.

2.4.9 Checking the filling level of the waste container

Check the filling level of the waste container from time to
time.
● With normal waste, empty the waste container when the
container is almost full, at the latest when the suction
performance decreases and dirt remains.
● In the case of heavy waste, a display can light up that
indicates a full waste container (weight measurement)
even though the waste container is not full.
