Cleaning device i.e. vacuum cleaner, has sensor arranged between opening and collector container, and evaluation device producing control signal depending upon concentration and/or quantity of sucked particles based on measuring signal

摘要

The device i.e. vacuum cleaner (1), has a collector container (9) for collecting sucked particles. A sensor (8) e.g. ring sensor, is provided in a flow channel (7) for producing a measuring signal depending on concentration and/or quantity of the sucked particles. The sensor is arranged between an opening (6) and the collector container. An evaluation device (12) produces a control signal depending upon the concentration and/or the quantity of the sucked particles based on the measuring signal, where the device is formed for performing an autonomous operation. An independent claim is also included for a method for operating a cleaning device.
