摘要： A handheld vacuum cleaner has a body with a handle, a nozzle assembly connected with the body via a suction pipe, and two or more rotating brush rollers for cleaning a surface. An input unit provides data for assisting a movement of the nozzle assembly. Two or more electric motors connected to the brush rollers are driven by a control unit in a clockwise or counter-clockwise direction. The input unit is arranged in the nozzle assembly and provided with an inertial measurement unit sensor that is configured to measure an accelerations along XY-axes and an angle of rotation around the Z-axis that is perpendicular to the cleaned surface. The control unit receives data from the input unit to drive the motors according to the measured accelerations along XY-axes and the angle of rotation about the Z-axis for assisting movement of the nozzle assembly in one or more predetermined directions.

摘要： A vacuum cleaner includes a body, an electrically-driven suction unit, a device for collecting dust, a suction channel, a nozzle communicating with the body through the suction channel, an intake device for ensuring an additional portion of air fed into the suction channel and being adjustable between an opened and a closed state, and a control unit for controlling the suction unit. The intake device is bi-directionally electrically connected to the control unit, so that transmission of data or signals between the intake device and the control unit is enabled. The control unit is configured to generate a signal for controlling the intake device in the event of detecting the cleaning start signal or the cleaning end signal. A method for operating a vacuum cleaner is also provided.
