A billiard table cleaning device for autonomous cleaning of a playing surface of a billiard table includes a housing, which defines an interior space and which has at least one linear side. A drive unit is engaged to a bottom of the housing and is configured to selectively motivate the housing across a playing surface of a billiard table. A vacuum assembly is engaged to the housing and is positioned in the interior space. The vacuum assembly suctions air and debris, such as chalk dust, through slots positioned in the bottom and expels filtered air through vents positioned in or proximate to a top of the housing, thereby cleaning the playing surface.

The present disclosure relates to a dust extractor (1) comprising a dust cyclone container (3) comprising a dust inlet (2) leading into the dust cyclone container (3), the dust extractor (1) further comprising a fine filter section (12) adapted to receive at least one fine filter part (15) downstream the dust cyclone container (3). A contaminated side of the fine filter part (15) is adapted to be fluidly connected to the dust cyclone container (3) via an air channel (47) that at least partly is comprised in a lid arrangement (13,14) and runs between a cyclone channel connecting rim (23) and a first fine filter section channel connecting rim (40), when the lid arrangement (13, 14) is positioned over the dust cyclone container (3) and the fine filter section (12). A first lid part (13) is releasably attachable to the dust cyclone container (3) and a second lid part (14) is releasably attachable to the fine filter section (12).

A surface cleaning apparatus having a housing, a suction nozzle, a suction source, a steam port, a steam supply system, and a flexible seal. The housing having a cleaning foot and an upper housing operably coupled to the cleaning foot. The suction source being fluidly connected to the suction nozzle by a working air conduit. The steam port having an aperture provided in the cleaning foot. The steam supply system having a steam nozzle with at least a portion that projects through the steam port. The flexible seal being provided at least around the steam nozzle.

A handheld vacuum cleaner includes a housing, a motor, and a dirt cup. The housing defines a top, a bottom, a motor chamber, a dirty air inlet at a front of the housing, a handle at the rear of the housing, a clean air outlet, and an airflow path from the dirty air inlet to the clean air outlet. The handle has a grip portion. The housing further includes a continuous elongate structural member extending from the dirty air inlet into the grip portion of the handle. The motor is disposed in the motor chamber. The dirt cup is coupled to the elongate structural member. The dirt cup is in fluid communication with the dirty air inlet and the motor. The elongate structural member defines a portion of the airflow path extending from the dirty air inlet.

A handy-stick type vacuum cleaner is disclosed. The disclosed vacuum cleaner comprises: a first part for collecting dust included in air suctioned to the inside through a suction hole; and a second part including a suction motor and a handle, wherein the first and second parts are hinge-connected so as to communicate with each other.

Described and shown is an article of manufacture, system and process for the collection and capture of a desired substance, either solid or liquid, such as debris or residue. The present invention is particularly useful for the cleanup of glue or other substance (e.g. excess caulking or silicone sealant) employed during fabrication or construction where one or more components are assembled and affixed together using a fluid adhesive or are sealed together, etc. Additionally, the present invention concerns a vacuum tool comprising a substance capture reservoir in communication with a substance collection conduit and attachable to a vacuum source for the collection and capture of various substances, both liquid and solid.

The present disclosure includes a first housing configured in a cylindrical shape, an inlet port provided to the first housing to suck air therein, an inlet pipe communicating with the inlet port and extending to a front side of the housing with a length-directional axis positioned side by side with a ground surface, a cyclone forming part provided to separate dust from air flowing into the first housing, a second housing communicating with the first housing and coupled to a rear side of the first housing, a fan provided with the second housing to provide a suction force to enable air to be sucked into the first housing through the inlet port, a battery provided to supply power to the fan, and a handle part including a handle base coupled to a top side of the first housing and a handle body connected to the handle base.

Apparatus and method for receiving and holding debris in a collection chamber of a vacuum cleaner. The collection chamber has an inlet opening through which debris-entrained air enters the collection chamber. When the vacuum cleaner is off, an internal valve prevents debris from leaving the collection chamber through the inlet opening. The internal valve is movable from a first sealed position, in which the internal valve covers the chamber inlet opening, to a second unsealed position in which the internal valve does not cover the chamber inlet opening.
