Connect the 35-mm vacuum hose (standard
equipment) onto the canister’s hose port by
sliding the wider end of the hose onto the port
then turning it to the right slightly to lock it in place.
The 35-mm hose can be connected to optional
accessories, including the Bosch VAC011
wand kit and the dust extraction hoods on
various power tools and accessories, including
those on Bosch router, planer, grinder, sander,
jigsaw, and hammer/drill tools and accessories.
The canister’s hose port also accept many
other vacuum hoses, including most 1-1/4”
hoses, 1-1/2” hoses, 2-1/2” hoses and other
Bosch hoses. (See Accessories, page 13 & 14)

There are four dust collection options: plastic
bag, paper bag, slurry bag or no bag.
• The filter cartridges must be installed
whether or not any of the bags are used.

• When dry-vacuuming such materials as dust
from drywall, plaster, cement, soot, and flour,
a dust bag should be inserted.
• Using a paper or slurry dust bag extends the
amount of time the unit operates at high
performance and extends the amount of time
it takes for the filter cartridge to become
clogged.
• A plastic bag can handle a heavier load
without tearing than the paper or slurry bags.
• Using any of the three types of Bosch dust
bags also makes waste disposal much
easier, eliminating the cloud of dust that is
created when canister contents are simply
poured out, helping to protect you and the
environment from exposure to the unwanted
particles and debris.

• The VAC022 heavy-duty wet/dry bags can
be used when vacuuming wet materials.
They are ideally suited for slurry-suction
applications.
