A handheld cleaner is provided and includes a dust cup assembly, including: a casing, a negative pressure device disposed in the casing and configured to suck an airflow from an environment into the casing, and a dedusting device disposed in the casing and configured to remove dust from the sucked airflow; and a handle assembly, including: a handle casing disposed to the casing and having a holding portion for user handholding, and a power supply device disposed at a top of the holding portion, and/or in the holding portion, and/or at a position in the handle casing opposite to the holding portion and electrically connected to the negative pressure device.

An autonomous vacuum cleaner includes an outer housing and a separator assembly that is removably received by the autonomous vacuum cleaner. A portion of the separator assembly defines a portion of at least two walls of the outer housing.

A vacuum cleaner has a portable cleaning unit that is removably mounted to the surface cleaning head. The vacuum cleaner is operable in a floor cleaning configuration in which the portable cleaning unit is mounted to the surface cleaning head and is part of the air flow path through the vacuum cleaner. The portable cleaning unit is also useable in a portable cleaning configuration in which the portable cleaning unit is removed from the surface cleaning head.

A low-profile dust collector assembly incorporates a low-profile cyclonic separator into a lid for a dust collection bucket. An outer lid ring can be formed of coffers that add strength to the lid and also reduce swirl in the air below the lid. The cyclonic separator has a shell rising from an inner circumference of the lid ring and has a horizontal inlet tube and central vertical outlet tube. A baffle for the separator includes a baffle plate fitted within the inner circumference and a turret of vertical members arranged with a top ring that fits onto the outlet tube. This compact arrangement has improved performance in airflow and dust separation. A spring clamp assists in fitting onto buckets over a range of diameters, and a pair of circumferential gaskets at right angles to one another form an air-tight seal.

A cyclone pre-separator for positioning on a particle collecting container, the cyclone pre-separator including a box-shaped housing and a cyclone unit arranged in the housing. The cyclone unit includes an air inlet, an air outlet, and a particle outlet arranged on a underside of the cyclone pre-separator, where the housing has an air inlet hose port connected to the air inlet and an air outlet hose port connected to the air outlet, and has lower housing couplers, adapted to provide a releasable, vertically tension-proof coupling to the particle collecting container, when the cyclone pre-separator is positioned on the particle collecting container.

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 has a cyclonic stage. A suction motor is provided in a housing. The housing has a first portion and a second portion wherein the second portion has a post-motor filter and the second portion is removably mounted to a first portion. The hand vac has a handle provided on the first portion of the housing. The sidewall of the second portion extends 360? around the cyclone axis of rotation and the suction motor axis of rotation, extends axially over the post-motor filter, forms part of an outer surface of the hand vacuum cleaner and comprises a rearmost removable sidewall portion of the hand vacuum cleaner body.

A surface cleaning apparatus comprises a surface cleaning head, an upright section moveably mounted to the surface cleaning head, and a portable cleaning unit removably mounted to the upright section and comprising an energy storage member and a portable cleaning unit suction motor. The energy storage member provides the portable cleaning unit suction motor with power at least when the portable cleaning unit is switched on and when the portable cleaning unit is removed from the upright section.

A handheld vacuum cleaner including a housing having a front end, a back end, a first side, and a second side, the housing further including a handle along a handle axis the handle axis extends in a direction from the back end toward the front end. A suction nozzle is along a suction nozzle axis that extends in a direction from the front end toward the back end. The handheld vacuum further includes a suction source operable to generate an airflow through the vacuum cleaner from the suction nozzle through a cyclonic separator to a clean air exhaust. The cyclonic separator includes a longitudinal axis that extends in a direction from the first side toward the second side and the handle axis and the suction nozzle axis intersect at an obtuse angle.

A hand vacuum cleaner has a horizontally disposed cyclone with a dirt outlet provided in a lower portion of the cyclone.
