    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.

    摘要: A cleaning system comprising a vacuum source, a current sensor, a recovery tank having a shutoff float configured to float on a surface of fluid within the recovery tank, and a controller. The vacuum source is in fluid communication with a suction inlet via first and second air paths within the recovery tank. The shutoff float is further configured to block the first air path upon the fluid within the recovery tank reaching a desired level. The controller is configured to receive, from the current sensor, a signal indicative of the current drawn by the vacuum source. The controller is further configured to determine, based on the current drawn by the vacuum source crossing a threshold, the fluid within the recovery tank has reached the desired level and control an operating element of the cleaning system upon determining the fluid within the recovery tank has reached the desired level.

    摘要: A pool-cleaning robot is provided, comprising: a robot body with a moving mechanism controlled to move the robot body forward or backward; wherein the robot body has a weight difference between its left and right sides; the moving mechanism includes a driver to drive the moving mechanism unilaterally; the robot body is provided with a fluid inlet-outlet, at least one first fluid inlet, and at least one first fluid outlet, which are communicated with each other. The fluid inlet-outlet is provided with a fluid driver that applies a suction force to the first fluid inlet or a discharge force to the first fluid outlet; a controller in the robot body, connected to and controlling the operation of the moving mechanism and the fluid driver; when the robot body is on a floor or walls of a pool, combinations of discharge forces, suction forces and weight differences steer the robot.

    摘要: A vacuum cleaning device comprises a housing having a dirty air inlet and a clean air outlet. An airflow path extends between the dirty air inlet and the clean air outlet. A dust container is mounted to the housing wherein the airflow path goes through the dust container. A motor fan assembly is mounted in the housing and is configured to create an air flow along the airflow path in a blow mode and a suction mode. A controller is configured to control the motor fan assembly in the blow mode and the suction mode. The controller is configured to control the motor fan assembly to pulse the motor fan assembly at first fan speed when in the blow mode.
