WET VACUUMING AND WET CLEANING
Use antifoam agent before wet working with
vacuum cleaner. Failure to use the antifoam
agent results in LOSS OF WARRANTY. When
you have finished wet working, leave the
vacuum cleaner operating on maximum power
for 30 s to let it dry.
Before using the wet cleaning function thoroughly vacuum
the surface to be cleaned.
Before operating the vacuum cleaner make sure the container
is empty and the water filter module and the filters are clean.
1 Press and hold the container lid opening button (2) and
lift the container lid.
2 Remove the container together with the water filter
module (filtration unit and partition) from the vacuum cleaner.
3 Remove the cleaning liquid container (25) by pulling it by
the handle and lifting it upwards.
4 Open the filler cap and fill the cleaning liquid container
(25) with cleaning agent (a mixture of cleaning fluid G 500
O Tens (31) and cold water). Use the amounts stated on the
fluid bottle label:
– "G 500 O Tens" manufactured by BUZIL, Germany.
●
Close the filler hole of cleaning liquid container with the
cap.
Before wet cleaning the carpet, check the
colour fasteness of cleaned carpet. Put a small
amount of prepared solution on white cloth and
clean manually the carpet at least visible place.
If the cloth is dyed, it means that the carpet
colours are not permanent and the carpet
cannot be cleaned using cleaning fluid G 500
O Tens.
5 Insert the cleaning liquid container (25) back to the
previous position and press the container to fix it correctly
(proceed in the reverse order as in case of removing the
container).
6 Insert the container together with the water filter module
(filtration unit and partition) to the vacuum cleaner.
For protection against the formation of foam or at its
formation, when cleaning fill the rear container with an
anti-foaming agent (31) recommended by the company
Bosch, in the amounts specified on the label:
– "G 478 Buz Defoam" manufactured by company BUZIL,
®
Germany.
●
Prepare the vacuum cleaner for operation according
to section B.
Use only the large or small atomizing nozzle for
wet vacuum cleaning.
●
The vacuum cleaner starts at the same power level it had
been working before it was turned off. Set the desired
power value (BWD420HYG, BWD421PET, BWD421PRO)
by pressing the power adjustment buttons +/- (9).

7 Press the pump switch (7).
The pump may only be switched on when
the cleaning liquid container is filled with the
solution of cleaning liquid and water. The lack
of cleaning liquid manifests in a loud operation
of the pump.
If the nozzle does not atomize water although the pump
is switched on, check if the following items are correctly
installed: the cleaning liquid container (press the container),
the fastening of the stub pipe in the valve in the base of
the vacuum cleaner or the fastening of the hose end in
the atomizing nozzle, check if the atomizing nozzle is not
clogged.
8 Press the button adjusting the inflow of water to the
nozzle on the hose handle.
If you press the button in a pulsating manner, the water shall
temporarily flow in a slower manner to the nozzle, if you
press and slide the button backwards, the water shall be
continuously supplied to the nozzle.
The handle is also equipped with a slider to adjust the
suction power. Do not uncover this opening while picking up
water or using the wet cleaning function.
Do not spray the cleaning liquid in one place
on the carpet for too long in order not to soak
the carpet.
●
You should to clean the carpet in such a way that during
and immediately after cleaning nobody walks on the
cleaned surface. After cleaning one part of the carpet
stop the spraying process and dry the carpet by sliding
the nozzle back and forth. Repeat until the whole surface
of the carpet is dried.
●
After ending the spraying process switch off the pump
and press the button adjusting the water inflow to the
nozzle for a moment to "release the pressure".
The vacuum cleaner is equipped with a float
which will automatically block the suction if the
foam filter II (33) is heavily dirty or the liquid
exceeds the maximum level. It is manifested
by a pulsing limitation of the motor power and
the lighting up of the clogged air inlet indicator
(12) (BWD420HYG, BWD421PET, BWD421PRO).
In such a case switch off the vacuum cleaner
by pressing the on/off button (8), unplug
the appliance, clean the filter and empty the
container.
Make sure the carpet is not soaked. It may
lead to a permanent deformation of the carpet
(folding).
