Inventum advises the use of original Inventum dust bags. Any damages to the product or accessories are not covered by the warranty when non-original dust bags are used.

Dust bags, filters and other accessories are available in the webshop of Inventum: https://www.inventum.eu/onderdelen/

When you choose not to use original Inventum dust bags, make sure the capacity of the dust bag is the same as the capacity of the vacuum cleaner.

Manufacturers of dust bags often use the term "Uni-bag" for dust bags which can be suitable for the Inventum vacuum cleaner.

When in doubt, contact the manufacturer concerned of the dust bags.

6 maintenance

Regularly check the hose, dust bag and filter to prevent problems. Empty the hose when it is clogged. Replace the dust bag when it is full and clean or replace the filters when they are dirty.

DUST BAGS AND FILTERS

The disposable dust bag and the motor filter are important parts for the efficiency of the vacuum cleaner. The dust bag is for collecting dirt, but at the same time the motor filter should be porous enough to allow sufficient air to pass through.

When the dust bag and motor filter are full, air is no longer able to pass, making it impossible for the vacuum cleaner to pick up dirt, irrespective of how powerful the motor is.

That is why it is important that the dust bag is replaced regularly and that the motor filter is replaced after each fourth dust bag replacement to guarantee optimum functioning of the vacuum cleaner. The air flow can quickly reduce when fine particles are picked up. Due to these fine particles, the performance of the vacuum cleaner will deteriorate, even if the dust bag is not yet full. It is therefore possible that the dust bag and motor filter should be replaced more frequently when picking up carpet cleaners, powders, dust generated during plastering work or other fine dust particles.

REPLACING THE DUST BAG AND MOTOR FILTER

Check that the vacuum cleaner is off and remove the plug from the socket before replacing the dust bag or motor filter.

Never use the vacuum cleaner without a dust bag or motor filter.

• Replace the dust bag when the dust bag full indicator becomes red or when the dust bag seems to be full.
• Open the dust bag compartment by pushing the handle upwards. Lift the cover.
• The motor filter [1] must be replaced after every fourth change of dust bag. Remove the motor filter by sliding it upwards. Place a new motor filter and place it back in place.
• Carefully slide the full dust bag out of the dust bag holder [2] and throw the full dust bag away.

• Slide a new dust bag [3] in the dust bag holder.
• Open the cover of the dust bag compartment. The opening of the dust bag is automatically pushed on the correct location when the cover is being closed. The cover of the dust bag compartment cannot be closed when the dust bag has not been placed correctly. Place the dust bag once more, in accordance with the instructions.

CLEANING OR REPLACING THE HEPA FILTER

The HEPA filter cleans the air one more time before it is ejected by the vacuum cleaner. Clean the HEPA filter at least once every six months or when it is very dusty. When the HEPA filter is damaged, it must be replaced by a new original filter.

• Press the clip to open the grille [4] under which the HEPA filter is located.
• Push the clip backwards and remove the HEPA filter [5].
• Clean the HEPA filter with lukewarm running water and allow the filter to dry in the air. Do not use cleaning agents or brushes.
• Only place the HEPA filter back once it is fully dry, or place a new HEPA filter.
• Place back the grille. Make sure it is properly attached.

Attention

• Only use the vacuum cleaner when all filters and a dust bag have been placed. If not, the suction power could be reduced or the motor could be damaged.
• Remove the plug from the socket before cleaning or replacing the filters.
• Torn or not properly sealing filters could damage the motor. When a filter is defective, it must be replaced by a new original filter.
  • The filters may not be cleaned in the dishwasher.
• Do not use a hair dryer to dry the filters.

STORAGE

The vacuum cleaner can be stored in two ways. Standing on its rear side - parking position - or its bottom side, so that the appliance takes up less space.

• Rewind the cord by pressing the button for automatic cord rewinding Ⓓ with your foot.
• Slide the button on the top side of the tube upwards and push the top part of the tube downwards to shorten the tube. When you let go of the sliding button, the tube will snap tight.
• Slide the floor nozzle in the holder on the bottom side of the vacuum cleaner - parking position - or place the vacuum cleaner upright and slide the floor nozzle in the holder [6] on the bottom side of the vacuum cleaner.
