A vacuum cleaner includes a foot assembly having a suction inlet thereon, a suction source in fluid communication with the suction inlet to produce a working airflow there through, and a dirt container in fluid communication with the suction inlet and suction source. The foot assembly further includes a body defined by a central portion and a pair of extension arms, a rotatable agitator on each extension arm, and a drive assembly configured to counter-rotate the agitators. The counter-rotating agitators are operable to cooperate with the suction source to direct dust and debris towards the suction inlet.

A surface cleaning apparatus includes a housing including an upright handle assembly and a base mounted to the upright handle assembly. The surface cleaning apparatus is further provided with a brushroll and a fluid delivery system comprising a fluid supply chamber and a fluid dispenser configured to dispense fluid to the brushroll.

An intelligent dust mop has an air inlet and at least one air outlet. A dust collection component and a mop component in a detachable connection with the dust collection component are disposed at the position of the air inlet. The dust collection component and the mop component are arranged at the front and the back in parallel, and the dust collection component floats up and down along the thickness direction of the mop component. The intelligent dust mop integrates dust collection and mopping functions, performing dust collection and mopping synchronously, thus realizing one-step cleaning. In addition, the dust collection component is positioned at the front end of the mop component, solving the problem where dust or hair on the ground moves along with the mopping, thus improving labor productivity.

An extraction cleaner for a floor surface includes an extraction nozzle. The extraction nozzle that defines a fluid flow path having an elongated nozzle opening, and includes one or more stiffening elements that stiffens the walls around the nozzle opening to prevent collapsing or deformation of the extraction nozzle during use.

An attachment to a portable vacuum or blower device that allows a user to direct the items collected by the portable vacuum or blower device to a separate container in an easy to carry assembly. The attachment to a portable vacuum or blower device has an adapter, an inlet and outlet assembly, and a lid. The lid detachably couples to a bucket or other container allowing the user to discard the bucket and collected items entirely or store the bucket with the collected items, depending on the items collected. The adapter provides attachments to popular portable vacuum or blower devices.

A handheld suction device may provide an ergonomic and convenient device for cleaning a variety of floor surface soils, including liquid soils. In different configurations, the device may provide a variety of different features to efficiently collect and hold liquid removed from the floor surface and/or prevent vacuum motor flooding if the operator over rotates the device when filled with liquid. In some applications, the handheld suction device provides an interchangeable system that allows the operator to switch between different suction attachments designed for picking up liquid soil and solid soil.

A hand held surface cleaning apparatus has a fluid flow path extending from a dirty fluid inlet provided at a front end of the hand held surface cleaning apparatus to a clean air outlet, the fluid flow path including a separator and a suction motor, wherein the suction motor is positioned rearward of the dirty fluid inlet. A separation stage comprising the separator, a solid collection chamber in communication with a separated element outlet of the separator and a separated liquid reservoir in communication with the solid collection chamber is provided. The solid collection chamber is positioned rearward of the separated liquid reservoir and the separator is positioned rearward of the solid collection chamber.

The present invention provides a gas-liquid separator with enhanced performance and easy operation, capable of performing gas-liquid separation such as advanced defoaming or degassing, and with a structure that facilitates easy CIP cleaning and disassembly cleaning, allowing it to meet sanitary specifications. This gas-liquid separator for gas-liquid separation performed by centrifugal force of an impeller mounted on a shaft which is supported by a bearing part and rotates in a casing comprises: the axial end of the impeller farther from the bearing part being positioned with clearance from the inner wall of the casing so as to slide on the inner wall of the casing; an exhaust outlet of the casing disposed in a position opposite the sliding impeller part; a vacuum device connected to the exhaust outlet; a discharge impeller part providing discharge force to the passing fluid formed around the axial end of the impeller; a discharge outlet of the casing disposed in a position opposite the discharge impeller part; and a suction inlet of the casing disposed in a position closer to the bearing part than the discharge outlet.

A surface cleaning apparatus includes a housing including an upright handle assembly and a base mounted to the upright handle assembly. The surface cleaning apparatus is further provided with a fluid delivery system comprising a fluid dispenser configured to dispense fluid and at least one fluid delivery channel forming a portion of a fluid delivery pathway. A method of removing debris and fluid from a floor surface using a surface cleaning apparatus is also provided.

An extraction cleaner for a floor surface includes an extraction nozzle. The extraction nozzle that defines a fluid flow path having an elongated nozzle opening, and includes one or more stiffening elements that stiffens the walls around the nozzle opening to prevent collapsing or deformation of the extraction nozzle during use.
