A handheld vacuum cleaner (10) includes a main body (22), a handle (98), and a receptacle (150) having an inlet (154). The handheld vacuum cleaner also includes a motor assembly (114) positioned within the main body, a dirty air inlet (14) positioned at a front of the handheld vacuum cleaner, a cyclonic chamber (30) in fluid communication with the dirty air inlet and the motor assembly, and a battery (138) including a first side surface (142) and a second side surface (146) opposite the first side surface. The battery is configured to be selectively received within the receptacle through the inlet. When the battery is positioned within the receptacle, each of the first side surface and the second side surface are at least 25 percent exposed through apertures at the respective first and second lateral sides (58, 62) of the main body such that the first and second side surfaces are graspable by a user.

A hand vacuum cleaner having a front end and a rear end positioned in a rearward direction rearward of the front end is described herein. The hand vacuum cleaner includes a dirty fluid inlet, an air treatment member downstream of the dirty fluid inlet, a pre-motor filter positioned in a pre-motor filter housing downstream from the air treatment member, a suction motor downstream of the pre-motor filter, an air flow path extending from the pre-motor filter to the suction motor, a clean air outlet downstream of the suction motor, and a handle. The pre-motor filter has a longitudinal length in the rearward direction that is longer than a transverse length in a direction transverse to the rearward direction. The pre-motor filter housing has first and second rearwardly extending pre-motor filter housing sidewalls and the pre-motor filter has first and second rearwardly extending pre-motor filter sidewalls that are positioned transversely inwardly of the pre-motor filter housing sidewalls. The pre-motor filter sidewalls are an upstream face of the pre-motor filter and the pre-motor filter has an inner cavity that is downstream of the upstream face.

A dust collection box for a dust extractor includes first and second air inlet chambers, an air inlet aperture through which air is drawn into the first air inlet chamber, an air outlet aperture through which air is dawn out of the second air outlet chamber, an air intermediate chamber formed in the housing, and a filter mounted within the housing. The filter includes a first part through which air passes from the air inlet chamber to the air outlet chamber, and a second part through which air passes from the air inlet chamber to the air intermediate chamber. An ambient air aperture is formed in the wall of the housing. A valve disposed proximate the ambient air aperture is switchable to connect the air intermediate chamber to only one of the air outlet chamber or the ambient air aperture.
