A cleaning apparatus comprises: a robot cleaner including a dust collection canister and a first suction device; and a docking station including a second suction device, which communicates with the dust container to suck air including foreign substances from the dust container in response to the robot cleaner being coupled to the docking station, and a trapping portion to capture the foreign substances included in the sucked air. The robot cleaner includes: a communication unit; and a control unit to control the first suction device in response to the robot cleaner being coupled to the docking station, controlling the communication unit to transmit a control command to the docking station, and periodically changing the suction force of either the first suction device and the second suction device.

An animal feces retrieval apparatus that is configured to facilitate the removal of animal feces for either disposal or re-use. The animal feces retrieval apparatus includes a frame that is secured to a user's back utilizing nylon shoulder straps. Operably coupled to the frame is the motor assembly wherein the motor assembly is operably coupled to a hose assembly. A controller is secured to the hose assembly and provides a user interface for control and operation of the animal feces retrieval apparatus. The controller provides a first mode and a second mode of operation of the animal feces retrieval apparatus. The motor assembly includes a motor that can be either combustible or electric. The animal feces retrieval apparatus includes a receiving receptacle having a liner configured to receive and retain incoming matter. The hose assembly includes a flexible section that facilitates directional manipulation of the nozzle of the hose assembly.

A vacuum cleaner assembly configured to be mounted in a vehicle. The vacuum cleaner assembly includes a vacuum module and a collector module configured to collect debris and operatively coupled to the vacuum module. The collector module includes a canister assembly with an intake port, an output port, and a flapper valve coupled to the intake port. An elbow assembly couples the vacuum module to the collector module and includes an intake end attached to the output port of the canister assembly. The intake end has a foam section disposed on a grill insert. Upon removal of the canister assembly from the collector module, the flapper valve moves to a closed position over the intake port of the canister assembly to keep debris contained in the canister assembly, and the grill insert and the foam section remain in place in the intake end of the elbow assembly.

An evacuation station for a mobile floor cleaning robot comprises a housing and an air treatment assembly removably mountable to the housing. The air treatment assembly is provided on a first lateral housing end. The first lateral housing end is provided with a housing air inlet that is downstream of the air treatment assembly air outlet whereby the air treatment assembly air outlet faces the housing air inlet.

A hand vacuum cleaner has a cyclone assembly positioned in the air flow path, the cyclone assembly comprising a cyclone chamber, the cyclone chamber having a front end, a rear end, a cyclone axis of rotation extending between the front and rear ends, a cyclone air inlet and a cyclone air outlet provided at the rear end of the cyclone chamber, wherein the rear end is rotationally moveable by a rotational mount between a closed position in which the cyclone is closed and an open position wherein a rear portion of the cyclone is open.

A vacuum cleaner, comprising: a housing; a motor unit provided in the housing and used for generating suction force; a dust cup provided on the housing and used for collecting sucked particles, the dust cup comprising a suction inlet; a battery for supplying power to the vacuum cleaner; a handle located on the housing; and a suction pipe unit having a storage state, wherein under the storage state, the suction pipe unit extends from the suction inlet on one side of the dust cup, across the handle, and to the other side of the dust cup along the length direction of the handle. The motor unit and the dust cup are located on the same straight line direction; the battery is provided on a side of the housing. The layout of the whole machine components of the present vacuum cleaner is optimized, and the performance of the vacuum cleaner is guaranteed under the premise of miniaturization.

A vacuum cleaner comprising a connecting device to a thermal control system of a vehicle, a flexible hose with a connection end on the connecting device for creating suction into the flexible hose, and a dust collecting box mounted onto the flexible hose.

A floor cleaner having a recovery tank, a suction source, and a filter basket. The suction source is configured to generate an airflow along a fluid flow path to draw fluid and debris from a surface to be cleaned into the recovery tank. The recovery tank has an outlet duct on a tank body. The filter basket is positioned in the outlet duct on the tank body and configured to filter debris from the airflow.

The present disclosure provides, in one aspect, an autonomous cleaning robot including a body, a drive operable to move the body across a floor surface, and a circuit board mounted below an upper surface of the body of the autonomous cleaning robot. The autonomous cleaning robot also includes one or more electrical contacts, a base of each electrical contact being mounted on the circuit board and a contact tip of each electrical contact being configured to protrude through a corresponding opening in the upper surface, wherein each electrical contact comprises a double curved structure to allow the electrical contact to be vertically flexible. The autonomous cleaning robot also includes a hinged lid including one or more contact pads, the one or more contact pads being configured to contact corresponding electrical contacts protruding through the upper surface as the lid is opened or closed.
