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.

A vacuum cleaner includes a suction pipe; a waste separation device; a main housing wherein a suction device including a motor fan is housed; and a gripping handle, the main housing including a first housing portion having a first branch in which the suction pipe is housed, a second branch forming a front part of the gripping handle and a third branch partially defining a reception chamber in which the suction device is housed, and a second housing portion placed in a rear portion of the vacuum cleaner, the second housing portion having a primary branch forming a rear portion of the gripping handle and a secondary branch partially defining the receiving chamber.

An electrical device, in particular in the form of a suction device (10) or a machine tool, with a housing (20) in which at least one electrical load, in particular an electric drive motor (11D), is arranged, wherein the electrical device has a power supply unit (80) with an energy storage receptacle (81), for the electrical power supply of the electrical load, in particular the drive motor (11D), in the interior of which at least two device interfaces (90A, 90B) for the detachable connection of a respective energy storage interface (190A, 190B) of an electrical energy storage (170A, 170B), in particular a battery pack, are arranged. The device interfaces (90A, 90B) are arranged on opposite side walls (83, 84) of the energy storage receptacle (81), so that the energy storages (170A, 170B) can be arranged on the device interfaces (90A, 90B) with mutually facing bottom walls (175).

A method of charging a rechargeable battery includes positioning a rail of the rechargeable battery into a groove defined by a housing of a battery charger, and positioning a switch between an ON position and an OFF position. The switch is positioned in the ON position when the rechargeable battery is connected to the charger and in the OFF position when the rechargeable battery is disconnected from the charger. The housing includes a barrier extending across the groove to prevent movement of the switch to the ON position when the rechargeable battery is disconnected from the charger. The method further includes conducting electrical current to the rechargeable battery through an electrical connection interface.

A portable vacuum cleaner comprises a housing including a storage space and a lid coupled to the housing. The lid is moveable between an open position, in which access to the storage space is provided, and a closed position, in which access to the storage space is blocked. The vacuum cleaner further comprises a handle coupled to the housing, a suction source supported in the housing, a debris collection chamber in fluid communication with the suction source, and a first battery receptacle on the housing. The first battery receptacle is configured to selectively receive a first battery pack that is configured to provide power to the suction source. The vacuum cleaner further comprises a hose port on the housing and in fluid communication with the suction source.

A handheld vacuum cleaner includes a frame, and a dust barrel and a locking portion mounted on the frame, wherein a front end of the dust barrel and the locking portion are movable relative to each other and are arranged opposite to each other; the dust barrel has a rotatable front cover at a front side thereof; and when the locking portion and the dust barrel move with respect to each other, the front cover is automatically rotatable to open, or close on the front side of the dust barrel due to limit by the locking portion.

The present disclosure relates to a cleaner system including: a cleaner; a cleaner station; and an imaginary plane including an imaginary suction flow path through line penetrating a suction flow path in a longitudinal direction and an imaginary suction motor axis defined by extending a rotation axis of a suction motor, in which when the cleaner is coupled to the cleaner station, the plane penetrates at least a part of the cleaner station, such that a center of gravity of the cleaner is disposed to pass through a space for maintaining balance of the station, and as a result, it is possible to stably support the cleaner and the station while preventing the cleaner and the station from falling down.

A handheld vacuum cleaner includes: a suction unit provided with an air outlet end; a dust-gas separation unit detachably connected to one end of the suction unit; a handle connected to another end of the suction unit; and an air outlet filter unit detachably disposed on an outside of the suction unit along an axial direction of the handle; wherein the air outlet filter unit is disposed at the air outlet end.

A surface cleaning apparatus comprises a base, a portable cleaning unit removably mounted to the base and comprising at least one air treatment member, a portable cleaning unit energy storage member and a portable cleaning unit suction motor. The portable cleaning unit suction motor is operable on power provided by the portable cleaning unit energy storage member when the portable cleaning unit is removed from the base. The surface cleaning apparatus comprises or is connectable to a power cord. When the portable cleaning unit is mounted to the base and when the surface cleaning apparatus is connected to an external source of power by the power cord, the portable cleaning unit energy storage member is chargeable on power provided by the power cord provided by the external source of power and the portable cleaning unit suction motor is concurrently operable on power provided by the power cord provided by the external source of power.
