5. Operating Instructions
5.1 Powering On/Off
Press the power button located on the top of the motor head to switch the vacuum cleaner on or off.
5.2 Dry Vacuuming
For dry dirt, ensure the fleece filter bag is installed in addition to the cartridge filter. Use the appropriate nozzle for the surface. The floor nozzle is suitable for larger areas, while the crevice nozzle is ideal for tight spaces like car interiors.
