The delayed action shutdown of the Automatic Start/Stop 
continues to run for up to 15 seconds in order to extract re-
sidual dust from the vacuum hose.

– To switch the vacuum cleaner 

off

, set the mode 

selector switch 

5

 to the “Off” symbol.

Wet Vacuuming



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 L) have only been proven for dry vacuuming.

– Remove the disposal bag 

23

 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 20).

– Switch the semi-automatic filter cleaning (SFC+) off (see 

“Deactivating the SFC+”, page 21).

The vacuum cleaner is equipped with filling-level sensors 

35

. 

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

5

 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.

To prevent the formation of mould after wet vacuuming:

– Take out the flat-fold filter 

24

 and allow it to dry well.

– Remove the vacuum cleaner lid 

8

 open the filter cover 

34

and allow both components to dry thoroughly.

Filter Cleaning

The filter cleaning system must be actuated at the latest when 
the vacuuming performance is no longer sufficient.

The filter cleaning frequency depends on the type and amount 
of dust. With regular usage, the maximum vacuuming perfor-
mance is maintained longer.

Semi-Automatic Filter Cleaning (see figure I)

With semi-automatic filter cleaning (SFC+), the lamellas of 
the flat-fold filter are cleaned from deposited dust by revers-
ing the airflow.

Note: 

The semi-automatic filter cleaning is factory-activated 

(SFC+ switch 

18

 in position 

I

).

–

Actuating the SFC+ filter cleaning

Shut or block off the nozzle or vacuum-hose opening with 
your palm.

Or, with the SFC+ module 

20

 mounted:

Press the actuator 

33

 down for approx. 10 seconds.

–

Deactivating the SFC+ 

Push the SFC+ switch 

18

 toward the front (position 

0

).

–

Activating the SFC+ 

Push the SFC+ switch 

18

 toward the rear (position 

I

).

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 

L

 vacuum cleaners that were in contaminated 

environments, the exterior as well as all machine parts should 
be cleaned or treated with sealants. When performing mainte-
nance 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.

Removing/Replacing the Flat-fold Filter 
(see figures J1 – J2)

Replace a damaged flat-fold filter 

24

 immediately.

– Pull the locking latch 

14

 and open the filter cover 

34

.

– Grasp the flat-fold filter 

24

 by the fins, pull up and remove.

– When taking out the flat-fold filter 

24

, remove any accumu-

lating dust and debris from the closing edge of the filter 
cover 

34

 using a moist cloth. 

– Insert the new flat-fold filter 

24

; observe proper and tight 

seating.

– Shut the filter cover 

34

 again (must be heard to engage).

Container

– Wipe out the container 

1

 from time to time with a commer-

cially available, non-scouring cleaning agent and allow to 
dry.
