A dust scraping device for a cleaning apparatus includes a dust cup and a removable cyclone separation unit arranged in the dust cup. The dust scraping device includes a dust scraping member. The dust scraping member has a connection portion extending in a removal direction of the cyclone separation unit, and a dust scraping portion extending to an interior of the dust cup in a direction perpendicular to the removal direction and slidably abutting against the cyclone separation unit. The dust scraping device is mounted at the dust cup, and the dust scraping portion scrapes off at least part of debris on an outer side of the cyclone separation unit when the cyclone separation unit is removed from the dust cup.

A vacuum accessory may include a head including a head body defining an inlet and a fitting interface, the head body extending from a fitting interface to a base and enclosing a cavity. A fitting includes a fitting body symmetrically disposed about a longitudinal axis of the fitting. The fitting body defines a fitting inlet, an outlet, and a flow path connecting the fitting inlet and the outlet. The fitting is connected to the head at the fitting interface and a fluid flow path fluidly connects the inlet and the outlet. A blade is removably coupled to the head and at least partially disposed within the cavity of the head. The blade includes a flat blade body that is coplanar with a reference plane dividing the fitting body and containing the longitudinal axis of the fitting.

A cleaning device includes a rolling brush mounted on a housing and can be in rolling contact with the ground. A waste collection region is integrally or separately provided in the housing, and the waste collection region is provided with a collection inlet provided corresponding to the rolling brush. Waste brought up by the rolling contact is collected into the waste collection region under the rotation action of the rolling brush. The housing is provided with one or more scraping guiders connected to the collection inlet, and each of the scraping guiders is in flexible pressure contact with the rolling brush or the ground, and is configured to scrape off residual waste absorbed by the rolling brush or residual waste on the ground and transfer the residual waste into the waste collection region.

Vacuum cleaner head (100) comprising a bottom sole (10) and wheels (30, 35) defining the ground clearance of the bottom sole and comprising at least one suction duct (20) open toward the ground and converging from an outer edge of the bottom sole (10) toward a suction orifice (15) connected to the vacuum cleaner, characterized in that the suction head comprises a sealing skirt (40) arranged around the periphery of the bottom sole (10), and in that the sealing skirt (40) has at least one opening (45) positioned opposite said at least one suction duct (20).

An ergonomic vacuum-assist scraper tool has an arcuately curved head in which a scraper blade is mounted at either of a front position or a rear position, a handle or grip portion, and a tubular connector portion adapted to receive a male or female vacuum hose fitting. The head has a cavity defined between front and back walls, with the front and back walls converging along an arc to a mouth or slot opening. The grip portion is hollow and tubular, extending proximally from the head, to the vacuum hose-accepting tubular connector. A scraper blade can be removably mounted at either of the blade mounting positions. The tool is formed of upper and lower halves that snap together along a partition line.

A shop vac includes a handle, a canister, a vacuum tube, and a pick-up device. The canister holds an enclosure that generates a negative pressure by forcing compressed, high velocity air through a orifice plug and out a muffler to create a vacuum in the enclosure. The vacuum in the enclosure is transferred to the vacuum tube and the pick-up device to pick up liquid or debris on a shop floor. The enclosure inside the canister includes a flow control valve such as a ball in cage device to prevent fluid from entering the enclosure. An evacuation spout is located at the bottom of the canister for draining the vacuum when the canister becomes full.

A suction nozzle and a vacuum cleaner are provided. The suction nozzle includes a lower case in which a suction inlet configured to suck dirt on a surface to be cleaned using suction force formed from a suction source and an inclined part including the suction inlet are formed in a bottom of the lower case which faces the surface to be cleaned, and an upper case coupled to an upper side of the lower case, wherein the inclined part is formed to be downwardly inclined towards a left side and a right side of the suction inlet from an arbitrary portion of the inclined part.

A vacuum accessory tool is provided. The vacuum accessory tool includes a body, a turbine, a generator, and a light source. The body defines a suction inlet, a fluid outlet, and a fluid flow path extending from the suction inlet to the fluid outlet. The turbine is rotatably mounted to the body in fluid communication with the fluid flow path to be rotated by fluid passing through the fluid flow path. The generator is coupled to the turbine such that rotation of the turbine rotates the shaft to generate power. The light source is electrically coupled to the generator and configured to receive the power generated by the generator to power the light source by the fluid passing through the fluid flow path.

A replacement head for a vacuum device includes a plastic tray, a filter and a pad. The plastic tray includes a dust chamber, a first connector lip and a second connector lip. An opening is provided that allows air, dust and debris to be drawn into the dust chamber during use. The connector lips are provided for attachment to a vacuum device. The pad is attached to the lower side of the plastic tray and is in contact with the floor during cleaning. The filter is connected to the plastic tray such that the filter substantially covers a top opening in the dust chamber.

A dust scraping device for a cleaning apparatus includes a dust cup and a removable cyclone separation unit arranged in the dust cup. The dust scraping device includes a dust scraping member. The dust scraping member has a connection portion extending in a removal direction of the cyclone separation unit, and a dust scraping portion extending to an interior of the dust cup in a direction perpendicular to the removal direction and slidably abutting against the cyclone separation unit. The dust scraping device is mounted at the dust cup, and the dust scraping portion scrapes off at least part of debris on an outer side of the cyclone separation unit when the cyclone separation unit is removed from the dust cup.
