Provided is a cleaning system including: a robot cleaner including a dust collecting device having a dirt outlet and an outlet door configured to open and close the dirt outlet; and a station including a collecting device configured to generate a suction force to suction dirt of the duct collecting device and a lever device provided with a lever configured to be fixable to the outlet door as the outlet door is being opened to allow the collecting device and the dust collecting device to communicate with each other, and a lever driving source configured to generate power for driving the lever.

The present disclosure discloses a hand-push leaf suction machine with an automatic outage function for toppling which includes a housing provided with an air duct, a fan fixedly arranged in the housing, a dust collecting box, ground wheels arranged on two sides of the housing and supported on ground, auxiliary wheels arranged on two sides of the housing and supported on the ground, and a push handle arranged at a rear end of the housing.

A suction apparatus includes a suction apparatus housing, including a filter for cleaning a suction flow, wherein the suction apparatus housing has at least one filter fastening element for securing the filter to the suction apparatus housing, and including a filter cleaning device for mechanically cleaning the filter. The filter, the filter fastening element and the filter cleaning device are arranged within the suction apparatus housing. The filter cleaning device includes an actuation device and a hammer device. The actuation device and the hammer device interact such that the hammer device can be actuated by using the actuation device and, when actuated, the hammer device applies at least one pulse to the filter securing element.

A robotic vacuum cleaner equipped with a holonomic drive that can drive in a given direction, e.g., north (assigned orientation), and move in a different direction, while maintaining its assigned orientation or that of any desired portion of the robot, such as an intake, or any other portion of the robot that is needed for a particular maneuver. The robotic vacuum cleaner includes a removable, chargeable battery system including a battery pack having batteries and a battery management system extending across all the batteries of the battery pack. A housing, including a top cover, surrounds the battery pack and the battery management system (BMS). The top cover extends over the BMS and includes a circuit board therein. A connector is at least partially connected to the BMS and extends through the housing. The connector is configured to transmit signals between the battery management system and the robotic vacuum cleaner.

A vacuum cleaner includes a suction inlet, a motor, and an impeller connected to the motor and operable to generate suction through the suction inlet upon operation of the motor. The vacuum cleaner further includes a power connector mounted to the vacuum cleaner and selectively connectable to a direct current (DC) power source and an alternating current (AC) power source. The power connector includes external terminals accessible from an exterior of the vacuum cleaner. The external terminals are configured for removable mechanical connection to each of the DC power source and an AC power supply cord such that the DC power source and the AC power supply cord are selectively and mechanically connectable to the same external power connector terminals.

In a vacuum cleaner electric blower is driven by power supplied by a secondary battery. A dust-collector is configured to catch and collect dust and dirt sucked by driving the electric blower. A detector is configured to detect a remaining amount of the secondary battery. A controller is configured to control suction force of the electric blower. In the case cleaning is finished when the remaining amount of the secondary battery detected by the detector is equal to or less than a predetermined value, the controller sets the parameter to reduce the suction force of the electric blower for the next cleaning. In the case cleaning is finished when the remaining amount of the secondary battery detected by the detector is not equal to or less than the predetermined value, the controller sets the parameter to increase the suction force of the electric blower for the next cleaning.

A surface cleaning device for removing debris from a surface is described. The surface cleaning device comprises a cleaning head comprising a housing, wherein the housing defines an inlet and comprises brush chambers; at least one vent coupled to a top portion of the housing; and a sweeper assembly coupled to the housing and comprising brushes having bristles, wherein the cleaning head is configured create a suction with a surface by directing air flow into the housing through the inlet and out of the housing through the at least one vent.

A rechargeable battery pack, applicable in a handheld vacuum cleaner, comprising: a polymer battery (1), comprising at least one polymer battery unit (11); a charger input terminal (3), electrically connected to the polymer battery (1), the battery pack charging electricity to the polymer battery (1) via the charger input terminal (3); an electrical interface (2), electrically connected to the polymer battery (1) for providing electricity to a handheld vacuum cleaner when the battery pack is connected to the handheld vacuum cleaner; and a PCM board (5), comprising a power supply management chip (U2) and a peripheral equalization circuit connected between the polymer battery (1) and the power supply management chip (U2). The internal resistance of the polymer battery in the rechargeable battery pack is less than the internal resistance of a cylindrical battery commonly used in products such as handheld vacuum cleaners and power tools, thus reducing the heat generated when discharging with a large current, and providing higher market value.

A vacuum cleaner assembly includes a vacuum body, a suction wand removably connected to the vacuum body, and an accessory removably connected to the suction wand. A suction motor is disposed in the vacuum body and is configured to create flow through a suction path. An accessory motor is disposed in the accessory. A first power source is configured to supply power to the suction motor and to the accessory motor. A second power source is configured to supply power to the suction motor and to the accessory motor when the first power source falls below a predetermined charge level.

Central vacuum cleaning system comprising a vacuum source including: a motor within a motor housing and a motor control circuit connected to the motor; a handle to be held by an operator, a flexible hose for connecting the handle to a conduit system that is connected to the vacuum source; a user input interface at an input location on the handle for controlling an operation of the motor through the motor control circuit; and a communications system to transfer control signals from the user input interface to the motor control circuit wherein the communications system comprises an RF wireless transceiver in the handle, and an RF wireless transceiver at the motor control circuit.
