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 nished 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 lter module and the lters are clean.

Press and hold the container lid opening button (2) and

lift the container lid.

Remove the container together with the water lter

module (ltration unit and partition) from the vacuum cleaner.

Remove the cleaning liquid container (25) by pulling it by

the handle and lifting it upwards.

Open the ller cap and ll the cleaning liquid container

(25) with cleaning agent (a mixture of cleaning uid G 500

O Tens (31) and cold water). Use the amounts stated on the

uid bottle label:

– “G 500 O Tens” manufactured by BUZIL, Germany.

●

Close the ller 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 uid G 500

O Tens.

Insert the cleaning liquid container (25) back to the

previous position and press the container to x it correctly

(proceed in the reverse order as in case of removing the

container).

Insert the container together with the water lter module

(ltration unit and partition) to the vacuum cleaner.

For protection against the formation of foam or at its

formation, when cleaning ll the rear container with an

anti-foaming agent (31) recommended by the company

Bosch, in the amounts specied 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).

Press the pump switch (7).

The pump may only be switched on when

the cleaning liquid container is lled 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.

Press the button adjusting the inow of water to the

nozzle on the hose handle.

If you press the button in a pulsating manner, the water shall

temporarily ow 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 inow to the

nozzle for a moment to “release the pressure”.

The vacuum cleaner is equipped with a oat

which will automatically block the suction if the

foam lter 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 lter and empty the

container.

Make sure the carpet is not soaked. It may

lead to a permanent deformation of the carpet

(folding).
