The present invention provides an autonomous cleaning robot device for cleaning in the animal husbandry environment. The cleaning robot is composed of a master machine (autonomous moving controller) and a slave machine (self-propelled cleaning head). The master machine and the slave machine are connected by a robotic arm and a traction hose. The robotic arm can adapt to the movement of the cleaning slave machine to reduce the resistance and secondary pollution or damage caused by friction between the traction cable and the ground during the movement. The traction hose combined with the robotic arm allows slave machine to enter and exit the fence without opening and closing the door to improve efficiency. In the treatment of dirt, the excrement is collected by a suction driving device, and is centrally collected in a storage tank, and then is compacted into blocks by the excrement compression device.

A hand vacuum cleaner having an air flow path extending from a dirty air inlet to a clean air outlet, with an air treatment member and a suction motor positioned in the air flow path, the dirty air inlet comprising a flow conduit having an inlet axis. A pistol grip handle is provided wherein the inlet axis intersects the pistol grip handle, and the suction motor is provided at a lower end of the pistol grip handle.

A hand vacuum cleaner with a finger grip area that is provided between a forward side of the handle and a rear side of the main body, and wherein the suction motor is positioned between the cyclone and the finger grip area and an axis that extends between the front of the cyclone and the handle extends through the suction motor.

Vacuums including a hollow wand and a vacuum accessory are provided herein. The vacuum accessory is configured to releasably couple with the hollow wand. A first terminal is disposed at a distal end of the hollow wand. A second terminal is disposed at a proximal end of the vacuum accessory. The second terminal is configured to correspondingly electrically mate with the first terminal. A biasing member is operably coupled to one of the first terminal and the second terminal, wherein, when the hollow wand is releasably coupled to the vacuum accessory, the biasing member is compressed such that the first terminal and the second terminal are maintained in mating contact with each other.

The disclosure relates to a method for operating a system that includes at least one suction device and at least one hand-held power tool. The method includes establishing a communications link between the suction device and the hand-held power tool by means of at least one suction device communication unit and at least one hand-held power tool communication unit, and transmitting at least one communication signal by means of the communications link from the hand-held power tool, in particular the hand-held power tool communication unit, to the suction device, in particular the suction device communication unit. When the suction device is switched on, at least one start signal is sent to the hand-held power tool, the hand-held power tool being activatable only if the start signal is received by the hand-held power tool.

A cleaner includes: a suction motor that generates suction force; a dust separation unit that is disposed behind the suction motor and separates dust from air sucked by the suction force of the suction motor; a dust container that stores dust separated by the dust separation unit; a handle disposed behind the dust separation unit; a battery housing disposed under the handle; and a battery that is detachably coupled to the battery housing and is separable downward from the battery housing.

A vacuum cleaner having a cyclone and dual inlet passages, each inlet passage extending to a tangential air inlet of the cyclone.

A surface cleaning apparatus comprising a surface cleaning head, a rigid air flow conduit and a hand vacuum cleaner removably mountable to an outlet end of the rigid wand. The hand vacuum cleaner comprises a main body, a cyclone provided at the front end of the hand vacuum cleaner, an inlet passage positioned at an upper end of the cyclone and a hand vacuum cleaner electrical connector provided on the front end of the hand vacuum cleaner adjacent the inlet passage. The hand vacuum cleaner electrical connector is releasably connectable with the outlet end electrical connector of the rigid wand. When the hand vacuum cleaner is mounted to the outlet end of the rigid wand, the longitudinally extending passage axis extends in a same direction as the cyclone axis of rotation and the suction motor axis of rotation extends in the same direction as the cyclone axis of rotation.

A swivel joint for a hand-held vacuum cleaner includes a first joint tube and a second joint tube rotatably connected at one end portions thereof with respect to each other, a connecting tube enabling communication between the first joint tube with the second joint tube, and a conductive assembly. The connecting tube is a corrugated flexible tube. The other end portions of the first and second joint tubes respectively connect a vacuum cleaner body with a dust suction tube of a vacuum cleaner or the dust suction tube with a dust suction head of the vacuum cleaner. The conductive assembly includes a first conductive interface and a second conductive interface respectively disposed on the first and second joint tubes and a conducting wire disposed inside the corrugated flexible tube. Two ends of the conducting wire connect with the first and second conductive interfaces, respectively.

A cleaning head (100) of a suction cleaning apparatus (10) comprising a brush head (140) configured for agitation cleaning during suction cleaning and the suction cleaning apparatus (10) comprising the cleaning head (100) are disclosed. The cleaning head (100) comprises a tubular housing comprising an inlet portion (122) including an inlet nozzle (132) which extends along a centre axis defining an axial direction, an outlet portion (124) having an outlet end, and an intermediate portion (126) interconnecting the inlet portion (122) and the outlet portion (124); the brush head (140) comprising a plurality of bristles (142) arranged to form a bristle skirt having a forward end; and a motor (152) configured to drive the brush head (140) to rotate or oscillate about a rotation axis.
