The present application discloses dust boxes, dust box assemblies and cleaning devices, wherein the dust box assembly includes a dust box and at least two fans. The dust box is formed with a holding cavity, a dust suction port and at least two air outlets, the dust suction port is connected to the holding cavity, the at least two air outlets are connected to the holding cavity. At least two fans are provided corresponding to at least two air outlets for creating an airflow that passes through the dust suction port, the holding chamber and the air outlet in sequence.

A power tool includes a power tool housing including a fluid inlet and a discharge outlet. A motor is supported by the power tool housing. A tool is configured to be moved relative to the housing by the motor. A fan is configured to be rotated by the motor, such that a fluid flow with debris generated by movement of the tool is drawn into the fluid inlet and through the discharge outlet. A filter is removably attached to the power tool housing. The filter includes a filter media configured to separate the debris from the flow of fluid. The filter media includes a collection container configured to store the debris. The filter also includes an opening in the filter media through which the flow of fluid with the debris enters the collection container, and a valve that is moveable between a closed position and an open position.

A docking station for a robotic vacuum cleaner has a pneumatic transfer mechanism that is used to direct air to the robotic vacuum cleaner to thereby transfer dirt from the robotic vacuum cleaner to a docking station.

A system for environmental maintenance includes a vacuum unit, an air purifier unit, a controller communicatively connected to the vacuum unit and the air purifier unit, a sweep sensor communicatively connected to the controller, and a movement sensor communicatively connected to the controller. The sweep sensor detects debris swept into a detectable vicinity of the sweep sensor and the controller turns on the vacuum unit upon detection by the sweep sensor. The controller turns on the air purifier unit upon the vacuum unit being turned on, and the air purifier unit cycles on for a period as programmed in the controller. The movement sensor detects movement in detectable vicinity of the movement sensor and the controller turns on the air purifier unit upon detection by the sweep sensor, if the air purifier is not already turned on.

A handheld vacuum cleaner includes: a suction unit provided with an air outlet end; a dust-gas separation unit detachably connected to one end of the suction unit; a handle connected to another end of the suction unit; and an air outlet filter unit detachably disposed on an outside of the suction unit along an axial direction of the handle; wherein the air outlet filter unit is disposed at the air outlet end.

A vacuum cleaner includes a suction inlet, a suction source configured to generate an airflow through the suction inlet to draw debris with the airflow through the suction inlet, and a separator assembly. The separator assembly includes a housing having an air inlet and an air outlet, a debris collection chamber within the housing, and an inner chamber formed within a shroud that defines a cyclone axis and has a perforated portion. The inner chamber has a first end and a second end. The first end has a tangential inlet. The second end is open toward the debris collection chamber. An outflow passageway is outside of the shroud and in fluid communication with the air outlet and a filter is in fluid communication with the outflow passageway.

A dust collector including a body with an intake portion and an exhaust portion includes a filter, a filter support that supports the filter, a motor case protruding from an inner surface of the body, and a vibration motor accommodated in the motor case. The body accommodates the filter support. A portion on the tip side of the motor case is at a position where it is allowed to come into contact with the filter support when the vibration motor is driven.

A cleaner is provided. The cleaner includes a transfer device, and a dust collecting apparatus connectable to the transfer device and configured to filter out rubbish transferred from the transfer device. The dust collecting apparatus includes a housing in which a first dust chamber is formed, and including a guide recessed inwardly from an outer surface, a handle configured to be movable on the outside of the housing and provided to cover at least a portion of the guide, a first rubbish removal member configured to be movable inside the housing based on the movement of the handle, and configured to discharge rubbish collected in the first dust chamber, and a link configured to connect the handle to the first rubbish removal member, and having a movement guided by the guide.

A robotic cleaning system may include a robotic cleaner having a robotic cleaner dust cup and a docking station having a docking station dust cup configured to fluidly couple to the robotic cleaner dust cup. The docking station dust cup may include a first debris collection chamber, a second debris collection chamber fluidly coupled to the first debris collection chamber, and a filter fluidly coupled to the first debris collection chamber and the second debris collection chamber.

A robotic vacuum cleaner docking station has a mechanical transfer mechanism that is used to transfer dirt from a robotic vacuum cleaner to a docking station.
