A hand vacuum cleaner comprises a main body has a driving handle and houses a suction motor and fan assembly, the suction motor and fan assembly having a suction motor axis of rotation wherein the driving handle has a hand grip portion that extends upwardly and forwardly when the hand vacuum cleaner is oriented with the upper end above the lower end. An air treatment member has a dirt collection region having an openable door provided on a front end of the air treatment member.

The present disclosure relates to a dust cup assembly and a handheld cleaner having the same, the dust cup assembly includes a casing having a central chamber, a dedusting chamber and a dust collecting chamber, wherein the central chamber is configured to have an upright columnar shape and comprises an air exhaust chamber and a mounting chamber in communication with each other in an up-and-down direction, the dedusting chamber is configured to have a closed annular cross section and surrounds the air exhaust chamber by one circle, the dust collecting chamber is located below the dedusting chamber, has a non-closed annular cross section and surrounds the mounting chamber by less than a circle; a negative pressure device, in which wherein at least a majority of the negative pressure device is provided in the mounting chamber and used to suck airflow from the environment into the casing; and a dedusting device provided in the dedusting chamber to remove dust from the sucked airflow.

The present disclosure relates to a dust cup assembly and a handheld cleaner having the same, the dust cup assembly includes a casing including a cup body with an open top, and a cleaner cover disposed at a top of the cup body and capable of being opened and closed; a negative pressure device provided in the cup body and used to suck airflow from an environment into the casing; and a dedusting device provided in the cup body, located above the negative pressure device and withdrawable from the top of the cup body when the cleaner cover is opened.

A cyclone assembly for a surface cleaning apparatus has a first cyclonic cleaning stage and a second cyclonic cleaning stage downstream from the first cyclonic cleaning stage. The first cyclonic cleaning stage has a first cyclonic stage air outlet and the second cyclonic cleaning stage has a plurality of second cyclonic stage cyclone air inlets and a second cyclonic stage air inlet end. The first cyclonic cleaning stage air outlet communicates directly with an annular flow region that extends around the second stage air inlet end of the second cyclonic stage.

A cyclone assembly includes a first cyclonic cleaning stage. The first cyclonic cleaning stage includes at least one first stage cyclone having a first stage cyclone chamber. Each first stage cyclone chamber has a height extending between a first stage cyclone chamber air inlet and a first stage cyclone dirt outlet. The cyclone assembly also includes a second cyclonic cleaning stage downstream from the first cyclonic cleaning stage. The second cyclonic cleaning stage includes a plurality of second stage cyclones in parallel. Each of the plurality of second stage cyclones has a height extending between a second stage cyclone chamber air inlet and a second stage cyclone dirt outlet. The second cyclonic cleaning stage has a larger number of second stage cyclones than the first cyclonic cleaning stage, and the height of each second stage cyclone chamber is greater than the height of each first stage cyclone chamber.

A hand vacuum cleaner has an air treatment member, a pre-motor filter housing having an openable door and a pre-motor filter media is provided in the pre-motor housing. The openable door is openable while the air treatment member is provided on the hand vacuum cleaner.

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.

A hand vacuum cleaner having a main body and cyclone unit provided at a front end of the main body. The cyclone unit has a front openable door.

A hand vacuum cleaner wherein the suction motor axis of rotation is generally parallel to the central longitudinal axis and when the hand vacuum cleaner is oriented with the upper end above the lower end, the suction motor axis of rotation is positioned above the central longitudinal axis.
