Cause 1: The dust compartment is full
To empty the dust compartment, hold the vacuum cleaner over a dustbin and press the release button to remove the dust compartment. Put the appliance aside. Then lift the dust bag out of the dust compartment with one hand and empty the dust compartment with your other hand.
Cause 2: The dust bag/filter is clogged
To maintain optimal suction performance, we advise you to clean the dust bag regularly.
Clean the dust bag with a brush or with a normal vacuum cleaner. If the dust bag is really dirty, you can clean it in cold or lukewarm water. Do not put it in the dishwasher. Make sure it is completely dry before you put it back into the vacuum cleaner.
Cause 3: The nozzle or other accessories are clogged
If the nozzle is clogged, press the release button to detach the dust compartment and remove the object or material that is blocking the nozzle. If the vacuum cleaner comes with accessories, check if they are clogged.
Cause 4: The batteries are not fully charged
Always make sure the switch is set to 0 if you want to charge the vacuum cleaner. If you place the vacuum cleaner onto the wall holder with the switch set to I or II instead of to 0, the charging light does not go on and the appliance is not charged. Also make sure that you place the vacuum cleaner onto the wall holder properly and that you place the charger plug into the wall socket properly.
