Maintenance

Check the hose, dust bag, and filters regularly to prevent any problems. If the hose is clogged, empty it. Replace the dust bag when it is full and clean or replace the filters when they are dirty.

DUSTBAGS AND FILTERS

The disposable dust bag and the motor filter play an important part in the efficiency of the vacuum cleaner. The dust bag is for capturing the dirt, but the motor filter needs to be porous enough to allow air to pass through at the same time. When the dust bag or motor filter is clogged, no air can pass through the cleaner and the vacuum cleaner will not clean, regardless of how powerful the unit is.

Therefore change the dust bag frequently and replace the motor filter every four dust bags, to ensure the vacuum cleaner operates at maximum efficiency. The airflow can be restricted very quickly by some fine particles and will decrease the performance even before the dust bag appears to be full. Therefore, the dust bag and motor filter may need to be changed more often when vacuuming carpet cleaners, powder, plaster dust, or other fine substances.

REPLACING THE DUST BAG AND REPLACING THE MOTOR FILTER

Make sure to turn off and unplug the vacuum cleaner before replacing the dust bag or the motor filter.
Do not use the vacuum cleaner without a motor filter or dust bag.

Change the dust bag when the full dust bag indicator turns red or when the dust bag appeal.
Open the dust bag compartment by pushing the clip upwards and lifting the lid.
The motor filter [1] should be replaced every four dust bags. Take out the motor filter by sliding it upwards.
Now you can replace it with a new one.
Slide the full dust bag carefully out of the dust bag frame [2] and dispose of it.
Slide a new dust bag [3] into the dust bag frame.
Close the dust bag compartment and push the lid back into place. The opening of the dust bag is automatically pushed into the right position when closing the lid. The lid of the dust bag compartment cannot be closed if the dust bag is not in place. If the lid cannot be closed, replace the dust bag again according to the instructions.

CLEANING OR REPLACING THE HEPA FILTER
The HEPA filter cleans the air one last time before it leaves the vacuum cleaner. Clean the HEPA filter at least once per six months or when it is very dirty. Replace a damaged HEPA filter with a new original HEPA filter.

Open the grid [4] that covers the HEPA filter by pushing the clip.
Pull the clip back and take out the HEPA filter [5].
Rinse the HEPA filter under lukewarm water and let it air dry completely. Do not use any cleaning agents or brushes.
Put the HEPA filter back into place, when dry, or replace it with a new one.
Replace the grid. Make sure that the grid is properly placed.

Attention

Use the vacuum cleaner only when the filters and a dust bag are in place. If not, it can lead to loss of suction power or damage to the motor.
Unplug the vacuum cleaner before cleaning or replacing the filters.
Torn filters or filters that do not fit properly can cause damage to the engine. Replace a damaged filter with an original new one.
Do not clean the filters in a dishwasher.
Do not use a hairdryer to dry the filters.

STORAGE

The vacuum cleaner can be stored in two ways. At the back – parking position – or at the bottom, uses less space.

Rewind the cord by pressing the cord rewinding foot pedal .
Push the slide button on the telescopic tube upwards and push the telescopic tube together to make it shorter. Release the slide button and let the tube snap into place.
Slide the floor nozzle in the attachment at the back of the device – parking position – or place the vacuum cleaner upright and slide the floor nozzle in the attachment [6] at the bottom of the appliance.
