A liquid vacuuming device for drawing off and vacuuming up liquids may include a housing (1), an extractor device formed by at least one extracting lip (7) for extracting and collecting the liquid in front of at least one vacuum mouth (5), a vacuuming device that features a motor-driven vacuum subassembly and is able to vacuum an air/liquid flow mixed with the liquid to be vacuumed up along a flow pathway from the vacuum mouth (5) through an intake channel (4) into the housing (1), a separating device (13) for separating the liquid from the air and a tank for receiving the separated liquid. The device may further include an on/off function that turns on the motorized drive or increases the motor power when pressure is exerted upon the extracting lip (7) and turns off the motorized drive or reduces the motor power when the pressure decreases. Similar functionality may be implemented by an orientation switch.

A portable hard surface cleaning appliance is provided, including a suction nozzle having a suction opening at which at least one squeegee lip is arranged, an electrical device having a suction turbine in flow connection with the suction nozzle for suctioning a liquid air mixture from the suction opening, an electric motor, an electronic control system, at least one rechargeable battery, a separating device arranged in the flow path between the suction nozzle and the suction turbine for separating liquid from the suctioned liquid air mixture, and a liquid tank for receiving the separated liquid. The hard surface cleaning appliance includes an inner housing arrangement and an outer housing arrangement, wherein the inner housing arrangement accommodates the separating device and the electrical device, and the outer housing arrangement surrounds the inner housing arrangement.

A nozzle assembly for a cleaning apparatus can include a brushroll, a motor disposed within the brushroll and configured to rotate the brushroll, a debris receptacle comprising a debris inlet. A scraper may be disposed above the debris inlet such that the scraper projects into the brushroll. A ramp can be formed on the scraper. The ramp may extend between an outer edge of the scraper above the debris inlet and into an interior region of the debris receptacle. The ramp can include a runoff surface configured to direct debris and liquid removed from the brushroll by the scraper as the brushroll rotates into the debris receptacle at a negative angle relative to a surface being cleaned. A squeegee assembly may be disposed across a full width of the nozzle assembly.

The present disclosure is generally directed to cleaning head for a vacuum system. The cleaning head includes an edge cleaner disposed on at least one side of the cleaning head to provide enhanced edge cleaning capabilities for the vacuum system.

The invention relates to a tongue cleaner for cleaning the tongue of a patient, comprising a main part and a handle section. The main part is paired with at least one cleaning region for cleaning and suctioning deposits on the tongue, wherein a first cleaning region has at least one elastic cleaning lip, which is being paired with at least one suction opening such that the suction opening is aligned at least parallel to the movement plane of the cleaning movement.

A system includes a dust removal head having an air input assembly, a vacuum output assembly, a high pressure zone and a low pressure zone. The air input assembly is configured for connection to a pressurized air source. The vacuum output assembly is configured for connection to a vacuum machine. The high pressure zone is in fluid communication with the air input assembly. The low pressure zone surrounds the high pressure zone, is in fluid communication with the high pressure zone, and is in fluid communication with the vacuum output assembly. A method of removing dust from a surface using a machine comprises directing pressurized air toward the surface to dislodge the dust from the surface and entrain the dust in a moving air stream within a high pressure zone shroud, conveying the dust-entrained air flow to a low pressure zone container and removing it using a vacuum.

A nozzle for a blower tube includes a collar configured to attach to the distal end of the blower tube and a blade defining a scraping edge. The blade transects the collar, forming top and second outlets that direct respective streams of air along both surfaces of the blade. The first outlet may have a greater cross-section than the second outlet, enhancing airflow distribution. The nozzle may feature a rounded bottom surface of the blade adjacent to the scraping edge and a relatively planar top surface. The collar may consist of adjustable, bifurcated portions for a secure fit. Additionally, a funnel downstream of the collar may funnels air against the blade's surfaces, and channelling formations on the blade's surface may help direct airflow. Internal vanes within the collar may further optimise air distribution across the blade.

A cleaner may include: a housing including a suction port; a drum brush in the housing and that is rotatable; and a scraper including: an edge including: a first inclined portion inclined along a first direction, a second inclined portion inclined along a second direction opposite to the first direction, and a recessed portion at least partially formed by the first inclined portion and the second inclined portion, wherein at least a portion of the scraper is configured to contact the drum brush, and the first inclined portion and the second inclined portion are configured so that, with rotation of the drum brush, a foreign substance attached to the drum brush is moved in the second direction.
