摘要： A cleaning apparatus for use by hand and/or with a robotic device expels fluid, air or liquid, from a perimeter of an open end of a housing of the cleaning apparatus. Simultaneously, a vacuum device is suctioning debris through the housing and into a vacuum port. The simultaneous use of suction and expelled fluid through a single apparatus generates turbulent airflow and effectively loosens and removes debris attached to surfaces without the need for the housing to contact the surfaces.

摘要： A blower system for drying a surface has an upright housing top that enables a user to maneuver the unit over various surfaces easily. A central feature of this system is a modular design for a unit that dries surfaces. This modular design enables a user to reconfigure the dryer as needed for a particular drying application. The modular capability and the upright standing design of the system allow a person to use this device and system for convenience. The blower of this device can be self-contained and detachable, which will enable a user to operate the drying function conveniently. The capability to detach a dryer module enables one to use this device for additional applications such as using the blower function to displace objects such as leaves.

摘要： A cleaning system for pavement joints controlled and driven by a motor. A wheeled housing carries a nozzle system where a stream of pressurized or forced air is directed through rotating nozzles to clean the joint surfaces. The rotational speed (RPM) of the motor is selectively controlled by actuation of a valve by the operator, and allows the operator to selectively control the rate of rotation of the nozzles are required by the state of the surface to be cleaned. A suction head is further movable over the joint surfaces to remove the debris dislodged by the nozzle system and airflow.

摘要： A brushless vacuum device may include a vacuum head having a bottom side, a first and second exterior wall, a front end, and a back end. The first exterior wall and second exterior wall may be positioned on the bottom side and may be coupled together at the front end. A suction aperture may be positioned proximate to the front end. A first plurality of jets may extend along the first exterior wall between the suction aperture and the back end. A second plurality of jets may extend along the second exterior wall between the suction aperture and the back end. A suction conduit may be in communication with the suction aperture and may generate negative air pressure in the suction aperture. A pressure conduit may generate a positive air pressure in the first plurality and second plurality of jets. Air exiting the jets may be collected by the suction aperture.

摘要： A spray-gun apparatus, comprising a spray-gun handle, a spray-gun tube-body, and a connection adapter; wherein the connection adapter is connected between the spray-gun handle and the spray-gun tube-body; wherein the first conduction tube is connected with the spray-gun handle and the spray-gun tube-body to use as a gas output path, and the second conduction tube is connected with a second cover-body to use as a gas suction path. Thereby, the gas sent from the spray-gun handle is blown out through the first conduction tube of the connection adapter and the spray-gun tube-body, and the water-sucking tube set inside the spray-gun tube-body will be made to spray liquid; and the second conduction tube of the connection adapter is used to connect a gas suction apparatus, so that the gas around the second conduction tube can be sucked into through the second conduction tube of the connection adapter.

摘要： A self-propelled cleaning device has a housing, a fan and a surface cleaning system for cleaning a surface to be cleaned. In order to also be able to clean an above-floor surface, in particular a plateau of a baseboard, the cleaning device also has an above-floor cleaning system for cleaning an above-floor surface vertically offset relative to the surface to be cleaned. The above-floor cleaning system has a flow connection to a suction and/or blower unit having a fan, the flow opening of which has a difference in height of roughly 3 cm or more relative to a standing surface of the cleaning device by comparison to a usual orientation of the cleaning device for a cleaning operation.
