The centrifugal force continuously transports dust into the dust container, significantly reducing the amount of dust entering the HEPA filter. This keeps the air channel clear and maintains high suction power over an extended period. There are various operating modes. With just one button, the electric self-locking function can be selected: for large areas and thus long runtimes, the button on the handle does not need to be held down continuously - simply press once to start and stop, making it easy and convenient. For quick cleaning in between, just hold the button as long as you want to vacuum. Quiet operation is ensured by Gedebao composite foam, which provides excellent sound insulation. The super sharp full-color display shows the most important information about the vacuum cleaner's operation in an animated and easily viewable format.
