The multi-tube filter can be cleaned during operation, i.e. while the machine is working.
Remove the hose from the front nozzle or the equipment
connected.
Block the suction.
(You can block the hose with a piece of cardboard, or you
can let the appliance suck on a level surface, for instance
a floor or the like).
Vacuum will now be formed inside the appliance.
By this, the springs of the multi-tube filter will contract a little.
Pull the ”lid” of the shock valve. (A regular pull, not a tug).
When the spring power overcomes the vacuum, the valve will open with a ”Purf”.
In order to equalize the pressure difference in the vacuum
cleaner and the pressure outside the vacuum cleaner, air will
flush backwards through the multi-tube filter and reject possible
accumulations. (Back flush).
In this way the multi-tube filter will be efficiently cleaned. The
effect of the cleaning can be seen on the vacuum indicator – if
not, the HEPA-filter may be blocked.
Repeat the process if necessary. (2-3 times should remove
even the most stubborn dirt.)
