Disclosed is a dust collector using fan heat, comprising a bottom shell (10) and an upper cover (50), wherein a rear end (12) of the bottom shell (10) is provided with an air outlet (122) and a fan assembly (30), the upper cover (50) covers and is connected to the bottom shell (10), air flow from the fan assembly (30) is discharged via the air outlet (122), and the fan assembly (30) is provided with a fan (33) and a stator (331); and the rear end (12) is provided with a lower frame edge (121), the fan assembly (30) and the air outlet (122) are enclosed to form a closed air flow channel (35), and a heat collector (40) is provided on the stator (331) in the air flow channel (35), and can rapidly collect heat and warm the air flow to form hot air flow. Also disclosed is a dust collector having an ironing function, which uses hot air flow to heat an ironing board (60) and then performs ironing and sterilization, so that the dust collector also implements recycling of energy resources while achieving the dust collection effect so as to perform effective sterilization and ironing.

A rod handheld two-in-one split-type vacuum cleaner having an independent dust-air separation and dust storage device is provided. A main device thereof is a handheld vacuum cleaner, and a push rod is a hollow rod. The rod handheld two-in-one split-type vacuum cleaner is provided with an independent dust-air separation and dust storage device on the push rod located above a floor brush and below the handheld vacuum cleaner. The dust-air separation and dust storage device can be independently removed to dump the dust. The main device, the push rod and the floor brush of the rod handheld two-in-one split-type vacuum cleaner can by split or assembled as different usage modes. The rod handheld two-in-one split-type vacuum cleaner can operate as a floor mopping vacuum cleaner, a handheld vacuum cleaner and a handheld vacuum cleaner with a long connecting tube.

A self-propelled dust-collecting robot includes a main body having wheels, a dust-collecting unit collecting dust on a floor surface, infrared sensors each including an infrared transmission element that emits infrared light toward the floor surface and an infrared reception element that receives the infrared light reflected at the floor surface, and a controller controlling the wheels on the basis of a reflectance of the infrared light obtained from each infrared sensor. The controller, during running, determines whether the reflectance is higher than or equal to a predetermined threshold value. Upon determining that the reflectance is higher than or equal to the threshold value, the controller controls the wheels to perform an avoidance action with the position where the reflectance is detected being a virtual wall, thereby to control the self-propelled dust-collecting robot to perform cleaning within a cleaning range defined by a reflection member.

A hand vacuum cleaner has a cyclone unit having a cyclone with a horizontal cyclone axis of rotation. The front end of the cyclone unit comprises a front door that is moveable between a closed position and an open position. A lock secures the front door in the closed position, the lock comprising an actuator, wherein the actuator is spaced towards the rear end of the cyclone.

Proposed is a cleaner. The cleaner includes a dustbin having an inlet formed on a first side thereof and an outlet formed on a second side thereof, the dustbin being provided with a cyclone part generating a cyclonic flow inside the cyclone part, and a motor part configured to communicate with the dustbin and generate a flow of air inside the dustbin. The dustbin includes a casing having the inlet and the outlet formed thereon, a separating wall dividing an inner space of the casing, a first dust storage part located in the inner space and communicating with the inlet, a first cap, a second dust storage part located in the inner space and communicating with the outlet, a second cap, and a lever.

A cleaning apparatus comprises a cleaner module provided with a module mounting portion, a wireless cleaning module removably mounted to the cleaner module, and a wired cleaning module provided with a canister, a connection hose connected from the canister to the cleaner, and a connector provided in the connection hose to be removably mounted to the cleaner module. A wired cleaning mode using the wired cleaning module and a wireless cleaning mode using the wireless cleaning module are selectively operated by mounting one of the connector of the wired cleaning module and the wireless cleaning module, to the module mounting portion.

A dust extraction device for a hand-held power tool includes a housing, a mechanical interface for releasably connecting the dust extraction device to the hand-held power tool, a dust-collecting chamber which is connected to a filter unit, and a filter-cleaning unit. The filter-cleaning unit has an impact element which is mounted moveably in and/or on the housing of the dust extraction device. The impact element is designed to act upon the filter unit directly with an impact-like force.
