Remove the water tank and pour the water into the sink. Check the water filter (15) regularly. If the
water filter is not replaced in time, calcium deposits may start to accumulate in it, causing damage to
the appliance or reducing its performance.
Cleaning air intake
If the appliance draws in a larger object, it may sometimes be
necessary to clean the air intake as well.
After removing the water tank and the filter from the main body,
also remove the air intake plastic cover (14), grasp the plastic
part in the pliers and pull it out. Clean the air intake and then
reinstall the cover.
The appliance should only be operated with the plastic air supply
cap installed.
HEPA filter cleaning
Press the dirt tank release button and pull it out of the appliance
body. The HEPA filter holder (2) and the HEPA filter frame (3) can
be washed in warm soapy water and then allowed to dry
completely naturally.
The HEPA filter should be cleaned at least once a month. If dirt
accumulates on the filter, it should be cleaned immediately. Dry
the filter completely before using it again. The appliance must
only be operated with the HEPA filter installed to prevent damage.
In the event of heavy soiling or poor vacuum cleaner
performance, replace it with a new one. We recommend replacing
it at least once every 6 months.
