A hand vacuum cleaner has an openable air treatment stage. The air treatment stage has a lower openable portion that is moveably mounted to a forward portion of the pre-motor filter housing.

A docking station for a robotic vacuum cleaner has a pneumatic transfer mechanism that is used to direct air to the robotic vacuum cleaner to thereby transfer dirt from the robotic vacuum cleaner to a docking station.

A vacuum cleaner including: a suctioning unit; a main body including a cyclone part for separating dust from suctioned air and a dust container for storing the separated dust, and a body cover for opening and closing the lower side of the body; a filter unit, disposed in the body, for filtering air separated from the dust; an actuating unit capable of moving in the body between the outside of the filter unit and the inner circumference surface of the body; an operating unit disposed outside the body which operates in order to move the actuating unit; a transmission unit penetrating the body and connecting the actuating unit with the operating unit; and an elastic member disposed outside the body which elastically supports the operating unit.

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 handheld vacuum cleaner includes a fluid flow path extending from a dirty air inlet to a clean air outlet, a main body, and a motor assembly positioned in the main body and along the fluid flow path. The motor defines a motor rotational axis. The handheld vacuum cleaner also includes a cyclonic chamber positioned in the fluid flow path. The cyclonic chamber defines a separator axis. The separator axis and the motor rotational axis form an obtuse angle extending between the cyclonic chamber and the motor assembly. The handheld vacuum cleaner further includes a pre-motor filter in the fluid flow path downstream from the cyclonic chamber and upstream from the motor assembly, a plenum in the fluid flow path immediately upstream from the motor assembly, and a sensor positioned on the plenum. The sensor is operable to measure a characteristic of the fluid flow path.
