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 and sweeper 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.

The disclosure relates to a handheld vacuum cleaner, comprising: a handle body having a first coupling part formed on one side in the longitudinal direction; a drive part body having a second coupling part formed on one side thereof so as to be detachably coupled to the first coupling part, a third coupling part formed on the other side, and a motor provided therein; and a filtration and discharge body having a first hollow part and a second hollow part, respectively formed at one side and the other side so as to communicate with each other, a dust receiving part formed between the first hollow part and the second hollow part so as to communicate with the first hollow part and the second hollow part, and a fourth coupling part formed on the inner surface of the first hollow part so as to be detachably coupled to the third coupling part. Therefore, each component can be completely disassembled and thus the volume can be greatly reduced, resulting in convenience in carrying or storage in a bag or the like, only the damaged components can be easily replaced at the time of partial component damage, thus reducing maintenance costs, and components of different capacity or shape can be replaced and used in combination depending on the purpose of use.

The present disclosure relates to a cleaner capable of easily separating a filter module from a main body of the cleaner and separating and assembling the separated filter module again. Disclosed is a cleaner including: a main body; a suction motor disposed in the main body and configured to generate a suction force so as to suction air; a dust separator separating dust from air by generating a cyclone flow in air introduced by the suction motor; and a filter module having a filter for filtering air discharged from the suction motor and being detachable from the main body. Here, the filter module is configured to be easily separated from the main body of the cleaner and assembled, such that the filter disposed inside the filter module may be easily cleaned or replaced.

A robot cleaner is provided. The robot cleaner includes a main body, a suction motor provided in the main body to generate a suction force, and a dust collector removably coupled to the main body to collect dust contained in air suctioned by the suction motor. The dust collector includes a first chamber to which the air, which is suctioned into the main body by the suction motor, is introduced, the first chamber including a filter to filter out dust in the suctioned air, and a second chamber arranged side by side with the first chamber, the second chamber including a connection port to which air, which is filtered b the filter in the first chamber, is introduced, and a cyclone dust separator to separate dust from the introduced air.

A hand vacuum cleaner has an upper end, a lower end, an air flow passage, a main body with a handle, an air treatment chamber and a suction motor. The air treatment chamber has an air outlet, the air outlet comprising a rigid porous member and a filter media that is removably positionable in the rigid porous member. The air treatment chamber is moveable to an open position in which the air treatment chamber is emptyable, and the rigid porous member is moveable within the air treatment chamber to an open position in which the filter media is removable.

A dirt collection and separation module can include a suction air flow around the perimeter of a tank to ingest fine dust that becomes airborne during the emptying process. Additionally, a trash can suction nozzle around a rim, a hand vacuum docking station, and an auxiliary suction nozzle that can fluidly couple the hand vacuum.

Vacuum cleaner consisting of a dust container (1) and filters (2) within this, and above these a control space (3) for air and in the control space control housings (3a, 3b, 3c, 3d) and above these the central housing (4) and the underpressure space, and above this the suction unit (5) and the suction unit engine (6), all the units (1, 3, 4, 5) being in mutual communication. The control space (3) contains control valves (7, 8) for the air flow, by means of which, in normal use, the air flow is directed through the suction opening (9) in the dust container (1) to the exhaust air opening (10) in the suction unit (5) (arrows 9a, 9b, 9c) and the control valves comprise closing means, which, by opening the valve (7a) to the outside air and by closing the valve (8a) directs the air flow in the dust container in the filter under underpressure partly from the normal flow direction (9a, 9b, 9c) to the opposite flow direction (11).

An autonomous vacuum cleaner operable to navigate about a surrounding environment to perform a surface cleaning operation without continuous human input. The vacuum cleaner includes a suction nozzle and a suction motor and a fan assembly operable to generate an airflow through the vacuum cleaner from the suction nozzle through a debris separator to a clean air exhaust. The suction motor and the fan assembly having an axis of rotation and a fan of the fan assembly rotatable about the axis of rotation. The axis of rotation is orientated horizontally. The debris separator includes a cyclonic separator operable to separate debris from the airflow and the cyclonic separator includes a cylindrical wall along a longitudinal axis, the longitudinal axis of the cyclonic separator being orientated horizontally.

In general, the present disclosure is directed to a hand-held surface cleaning device that includes a relatively compact form-factor to allow users to store the same in a nearby location (e.g., in a drawer, in an associated charging dock, on a table top) for easy access to perform relatively small cleaning tasks that would otherwise require retrieving a full-size vacuum from storage. A hand-held surface cleaning device consistent with aspects of the present disclosure includes a body (or body portion) with a motor, power source and dust cup disposed therein. The body portion also functions as a handgrip to allow the hand-held surface cleaning device to be operated by one hand, for example.

The present application provides a floor sweeping robot system with an automatic dust collection function, which sucks garbage in a water-dust integrated box and automatically treats garbage inside a floor sweeping robot, thereby solving problems for consumers. Accordingly, the frequency of cleaning the machine and recycling garbage is reduced, and the cleaning operation is performed at one time, so that the cleaning efficiency is improved greatly. The integrated design of the water-dust integrated box can greatly save the space, and is lower in production cost and more convenient for a user to clean.
