A handheld vacuum cleaner includes a housing, a motor, and a dirt cup. The housing defines a top, a bottom, a motor chamber, a dirty air inlet at a front of the housing, a handle at the rear of the housing, a clean air outlet, and an airflow path from the dirty air inlet to the clean air outlet. The handle has a grip portion. The housing further includes a continuous elongate structural member extending from the dirty air inlet into the grip portion of the handle. The motor is disposed in the motor chamber. The dirt cup is coupled to the elongate structural member. The dirt cup is in fluid communication with the dirty air inlet and the motor. The elongate structural member defines a portion of the airflow path extending from the dirty air inlet.

An auto clean machine comprising: a height computing device; and an obstacle determining device. The height computing device is turned on to compute a height or an overhang height of an obstacle when the obstacle determining device determines the obstacle exists in a predetermined region of the auto clean machine. The height computing device does not compute the height and the overhang height when the obstacle determining device does not determine the obstacle exists in the predetermined region.

A vacuum cleaner having a hand unit and an elongated member having a nozzle end portion and a handle end portion. The vacuum cleaner has a valve arranged at the nozzle end portion, the valve having a valve member being movable between a first and a second position. In the first position the valve member directs an airflow from a floor nozzle to the hand unit while preventing an airflow to flow through the handle end portion. In the second position the valve member directs the airflow from the floor nozzle to the handle end portion and to the hand unit. Vacuum cleaning may be performed with the floor nozzle both when the hand unit is connected at the nozzle end and at the handle end.

Provided is a robot cleaner. The artificial intelligence robot cleaner includes a traveling driving unit configured to allow the artificial intelligence robot cleaner to travel in an indoor space of a home, a cleaning unit configured to remove pollutants, a sensor configured to acquire data that is used to identify a plurality of members, and a processor configured to control the traveling driving unit and the cleaning unit so as to determine one or more subordinate spaces corresponding to each of the plurality of members among a plurality of subordinate spaces by using the data and a map of the indoor space, determine a return time of some or all of the plurality of members, determine a cleaning priority of the plurality of subordinate spaces based on the return time, and perform cleaning according to the cleaning priority.

The present invention relates to a robot vacuum cleaner comprising sub-wheels having variable rotational positions, the robot vacuum cleaner comprising subframes rotatably attached to main frames to ground the sub-wheels when in a constrained state.

A cleaner head for a vacuum cleaning appliance includes a housing which defines a suction chamber. The suction chamber has a suction inlet through which air enters the suction chamber, and a suction port through which air exits the suction chamber. The cleaner head includes a plurality of casters for supporting the cleaner head. Each caster is rotatable relative to the housing about a first axis which is perpendicular to the suction inlet. Each caster is also rotatable relative to the housing about a second axis perpendicular to the first axis. The cleaner head further includes a plurality of guide members for guiding into the suction chamber debris entrained within air drawn towards the suction inlet. Each guide member is arranged to rotate with a respective caster about the first axis.

The present disclosure relates to a robot cleaner, more particularly, to a robot cleaner that may rotate auxiliary wheels to run over a tilted route or an obstacle, when cannot run over a tilted route or an obstacle because main wheels are not contacting with the floor.

Provided are a storage base and a vacuum cleaner assembly having the same. The storage base is configured to store a vacuum cleaner. The storage base includes a first component connecting portion configured to store a first component of the vacuum cleaner and a second component storage portion configured to store a second component of the vacuum cleaner. The first component connecting portion and the second component storing portion are staggered with each other in a circumferential direction of the storage base.

A docking station for a mobile cleaning robot can include a housing. The housing can define or comprise a pad receptacle and a pad dispenser. The pad receptacle can be configured to receive a soiled pad from a pad tray of the mobile cleaning robot. The pad dispenser can be configured to provide a fresh pad to the pad tray of the mobile cleaning robot.

Provided is a cleaner having improved cleaning efficiency. The cleaner includes a main body having a intake provided to suction an object to be cleaned and a suction device having a brush chamber that communicates with the intake and a brush accommodated in the brush chamber, wherein the brush includes a brush body rotatably coupled to the brush chamber, a blade protruding in a radial direction of the brush body, and prevention members formed to be inclined from a central portion of the brush body to opposite side ends of the brush body to prevent foreign substance introduced into the brush chamber from being wound around the blade.
