A portable vacuum cleaner comprises a housing including a storage space and a lid coupled to the housing. The lid is moveable between an open position, in which access to the storage space is provided, and a closed position, in which access to the storage space is blocked. The vacuum cleaner further comprises a handle coupled to the housing, a suction source supported in the housing, a debris collection chamber in fluid communication with the suction source, and a first battery receptacle on the housing. The first battery receptacle is configured to selectively receive a first battery pack that is configured to provide power to the suction source. The vacuum cleaner further comprises a hose port on the housing and in fluid communication with the suction source.

A dust collection box for a dust extractor includes first and second air inlet chambers, an air inlet aperture through which air is drawn into the first air inlet chamber, an air outlet aperture through which air is dawn out of the second air outlet chamber, an air intermediate chamber formed in the housing, and a filter mounted within the housing. The filter includes a first part through which air passes from the air inlet chamber to the air outlet chamber, and a second part through which air passes from the air inlet chamber to the air intermediate chamber. An ambient air aperture is formed in the wall of the housing. A valve disposed proximate the ambient air aperture is switchable to connect the air intermediate chamber to only one of the air outlet chamber or the ambient air aperture.

An air purifying system may include a main air purifier placed in an indoor space, a handheld air purifier mounted on the main air purifier, and an air quality sensor IOT device that communicates with the main air purifier. The air quality sensor IOT device may be fixed in an outdoor space adjacent to the indoor space, or may be carried by a user to measure air quality data while the user travels. The main air purifier may automatically operate based on air quality data received from the air quality sensor IOT device.

The present application discloses a cleaning device and its dust box. The cleaning device may comprise a body, a dust box, and at least two fans. The dust box may be provided for connection to the body, the at least two fans are provided in the body for forming an airflow into and out of the dust box through the apparatus body. The dust box may be provided such that the airflow formed by each of the at least two fans can flow out of the dust box in different directions.

A cleaner including a cyclone dust collector and a filter has a shortened total length. The cleaner includes a main unit including a suction port, a cyclone unit including a cyclone dust collector having an outlet and a cylinder located rearward from the outlet and having an opening larger than the outlet, and a filter located frontward from the suction port and covering the opening.

A cleaning bin mountable to an autonomous cleaning robot operable to receive debris from a floor surface includes a debris compartment to receive a first portion of debris separated from the airflow and a particulate compartment to receive a second portion of debris separated from the airflow. The cleaning bin also includes a debris separation cone having an inner conduit defining an upper opening and lower opening. The upper opening receives the airflow from the air channel. The inner conduit tapers from the upper opening to the lower opening such that the airflow forms a cyclone within the inner conduit.

A mobile cleaning robot includes a removable filter unit configured to receive a supply airflow generated by a blower and to filter debris from the supply airflow, a filter seat, a filter access opening, a filter access door, and a filter presence system. The filter access door is pivotable between a closed position, wherein the filter access door covers the filter access opening, and an open position, wherein the filter access door is displaced from the filter access opening to permit access to the filter seat. The filter presence system is configured to: permit the filter access door to move from the open position into the closed position when the filter unit is disposed in the filter seat; and prevent the filter access door from being moved into the closed position when the filter unit is not disposed in the filter seat. The filter presence system includes a lift arm movable between an extended position and a retracted position. When the filter access door is open, the lift arm assumes the extended position to receive the filter unit in the filter seat. Moving the filter access door from the open position into the closed position when the filter unit is disposed in the filter seat causes the lift arm to move to the retracted position.

A surface cleaning apparatus comprises an air treatment chamber having a porous member at the air outlet. The air treatment chamber has a stationary portion and an openable portion, the openable portion is moveably mounted by a mount between a closed position in which the air treatment chamber is closed and an open position in which the air treatment chamber is open. The porous member is moveable concurrently with the openable portion. When the openable portion is in the closed position, the openable portion and the stationery portion abut along peripheral edges that extend along a length of the air treatment chamber sidewall.

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container.

A dust collecting device for a power tool, the dust collecting device having a lamella filter and a rotatable shaft. In the collecting container of the dust collecting device, the lamellae of the filter can be set in an axial movement by a rotary movement of the shaft which is interrupted when the filter lamellae arrive in the region of release of the shaft. The release enables the lamellae to return to their original position, the return of the lamellae to this original position causing the lamellae to vibrate, which leads to the filter being cleaned. A power tool which has a proposed dust collecting device, as well as a method for operating a power tool and for cleaning a filter is also provided.
