Abstract: A floor nozzle apparatus is provided, including a receiving chamber having a receiving space, at least one cleaning roller arranged in the receiving space and rotatable about an axis of rotation, and a suction connector on which a suction stream acts during operation, wherein there is arranged between the receiving space and the suction connector a funnel-shaped duct device opening into the receiving space by an orifice and connecting to the suction connector or including the suction connector, and wherein the orifice has a width, in a direction of width parallel to the axis of rotation, having at least one of the following: (i) the width of the orifice is at least 30% of a width of the receiving space in the direction of width; (ii) the width of the orifice is at least three times a width of an opening in the suction connector in the direction of width.

Abstract: A drying apparatus for motor vehicles is provided, which is movable in a treatment direction relative to the surface of a motor vehicle to be dried. The drying apparatus includes a plurality of nozzles suppliable with drying air, a nozzle support device, and a holding device holding the nozzle support device. The nozzle support device includes at least two nozzle supporting parts, each holding at least one nozzle, arranged side by side transversely to the treatment direction. The drying apparatus includes an adjusting device for transferring the nozzle supporting parts relative to one another between at least two relative positions in which the parts are oriented at different angles to one another. The relative positions include an angular position in which air flows exiting the nozzles have or form an apex region on the leading side with respect to the treatment direction. A vehicle wash installation is also provided.

Abstract: The invention relates to a vehicle wash facility, including a drying apparatus for drying a motor vehicle which is held to a holding device of the vehicle wash facility and includes a nozzle support device, at least one blower and a plurality of nozzles which are arranged at a distance relative to one another at the nozzle support device and which can be supplied with drying air by the at least one blower, wherein the nozzles are flat jet nozzles, each providing a flow of air that spreads out in a fan shape.
