– To switch the vacuum cleaner 

off

, set the mode 

selector switch 

7

 to the “Off” symbol.

When the alarm sounds, the vacuum cleaner must be checked 
as described under “Correction of Malfunctions”.

Wet Vacuuming (see figure H)



Do not vacuum inflammable or explosive fluids; for ex-
ample, benzene, oil, alcohol, solvents. Do not vacuum 
hot or burning dust. Do not operate the machine in 
rooms where the danger of an explosion exists. 

The 

dusts, vapours or fluids can ignite or explode.



The vacuum cleaner may not be used as a water pump. 

The vacuum cleaner is intended for vacuuming air and wa-
ter mixtures.



Before any work on the vacuum cleaner itself, pull the 
mains plug.

Note: 

The requirements for the ingress degree (dust category 

M) have only been proven for dry vacuuming.

– Remove the disposal bag 

29

 or the dust bag and empty the 

container 

1

 before wet vacuuming.

Note: 

For easier disposal when vacuuming liquid-solid mix-

tures, use a wet filter bag (accessory), which separates liq-
uids from solids.

– Mount the rubber lips into the floor nozzle (see “Inserting 

the Rubber Lip”, page 22).

– Switch the automatic filter cleaning (AFC) off (see “Deacti-

vating the AFC”, page 23).

The vacuum cleaner is equipped with filling-level sensors 

40

. 

When the maximum filling height is reached, the vacuum 
cleaner switches off. Set the mode selector switch 

7

 to the 

“off” symbol.

Note: 

When vacuuming non-conductive liquids (e. g. drilling 

emulsion, oil and grease), the vacuum cleaner is not switched 
off when the container is full. The level must be monitored 
continuously and the container emptied in time.

When the alarm sounds while wet vacuuming, the operational 
safety of the VAC is not impaired. No measures are required to 
correct the malfunction.

– Pull the drain hose 

23

 from its holder and drain the dirty 

water via the drain hose.

– For transport of the vacuum cleaner, screw the plug cap 

2

onto the hose connection piece 

3

.

To prevent the formation of mould after wet vacuuming:

– Take out the flat-fold filter 

30

 and allow it to dry well.

– Remove the vacuum cleaner lid 

13

 open the filter cover 

39

and allow both components to dry thoroughly.

Filter Cleaning

Automatic filter cleaning (see figure I)

In automatic filter cleaning mode (AFC = Automatic Filter 
Cleaning), the flat-fold filter 

30

 is cleaned every 15 seconds 

by means of air blasts (pulsating noise).
The filter cleaning system must be actuated at the latest when 
the vacuuming performance is no longer sufficient.
Regular use of the filter cleaning feature increases the tool life 
of the filter.
To achieve ideal filter tool life, deactivate the automatic filter 
cleaning in exceptional cases, e. g., when vacuuming pure liq-
uids or when working with a paper filter bag.
A flat-fold filter contaminated only on the surface is fully func-
tional. Manual cleaning of the flat-fold filter by striking/tap-
ping against it or blowing it out is not necessary, and can even 
damage the filter.

Note: 

The automatic filter cleaning is factory-set.

Switching the automatic filter cleaning on/off is only possible, 
when the VAC is running.

Maintenance and Service

Maintenance and Cleaning



Before any work on the vacuum cleaner itself, pull the 
mains plug.



For safe and proper working, always keep the vacuum 
cleaner and ventilation slots clean.



Wear a dust protection mask when maintaining and 
cleaning the vacuum cleaner.

If the replacement of the supply cord is necessary, this has to 
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
A dust-technical inspection is to be carried out at least once 
every year by the manufacturer or an instructed person, e. g. 
for damage of the filter, tightness against leakage of the vacu-
um cleaner and function of the control/monitoring unit.

For category 

M

 vacuum cleaners that were in contaminated en-

vironments, the exterior as well as all machine parts should be 
cleaned or treated with sealants. When performing maintenance 
and repair work, all contaminated components that cannot be 
cleaned to satisfactory must be disposed of. Such components 
must be disposed of in impermeable plastic bags conforming 
with the valid regulations for the disposal of such waste.

For maintenance on behalf of the user, the vacuum cleaner 
must be disassembled, cleaned and maintained as far as fea-
sible, without causing a risk for the maintenance personnel or 
other persons. Prior to disassembly, the vacuum cleaner 
should be cleaned in order to prevent any risks. The room/en-
closure in which the vacuum cleaner is disassembled should 
be well ventilated. Wear personal protective equipment dur-
ing maintenance. After the maintenance, the maintenance ar-
ea should be cleaned.
