A cleaner comprises a housing having a dust collection chamber formed in the housing and configured to open and close, a main body movable relative to the housing between a first position whereby the main body closes the dust collection chamber and a second position whereby the main body opens the dust collection chamber, and a motor filter mountable to and demountable from the main body, wherein the main body includes a fan motor unit to generate a suction force, and a shutter device mountable into the main body and configured to open and close a flow path between the motor filter and the fan motor unit.

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 modular particle collection system includes a hollow lower member, a hollow upper member separably attached to the hollow lower member, a collection container separably attached to a longitudinal end of the hollow lower member opposite the hollow upper member, an inlet portion extending radially from the hollow lower member and configured to be fitted to a first portion of a vacuum system, a particulate filter, and an outlet portion extending radially outward from the hollow upper member and configured to be fitted to a second portion of vacuum system. Additional modular particle collection systems and a method of making a modular collection system are also disclosed.

A vacuum cleaner includes a main body in which a motor fan is housed; a control device that can be operated by a user; an activation device that can be operated by a user; and an electronic control unit that is configured to control the operation of the motor fan in a first operating mode when the control device is actuated by a user and to control the operation of the motor fan in a second operating mode when the activation device is actuated by a user. The electronic control unit includes an electronic board equipped with a first contact and a second contact, the control device being configured to activate the first contact when the control device is operated by a user, and the activation device being configured to activate the second contact when the activation device is operated by a user.

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.
