Abstract: A vacuum nozzle system has a vacuum nozzle with an inlet opening for engaging a surface to be vacuumed and an outlet opening for connection to a vacuum supply hose. The inlet opening is delimited by a circumferential end face. The nozzle defining a vacuum flow direction from the inlet opening to the outlet opening. A holder bracket has a holder for holding the nozzle. The holder is disposed downstream of the end face in a vacuum flow in the vacuum flow direction when the nozzle is in a retained position on the holder bracket.

Abstract: A method of operating a carwash includes driving a vehicle to a point of sale station of the carwash, purchasing a carwash transaction, and taking a first picture of a license plate number of the vehicle after the completion of the purchase of the carwash transaction at the point of sale station. The license plate number is associated with the carwash transaction as a carwash ticket. The vehicle is then sent to a carwash queue disposed downstream of the point of sale station. The carwash ticket information is sent to a carwash tunnel. A second picture of the license plate number of the vehicle is taken right as it approaches the carwash tunnel. The license plate number is associated with the carwash ticket and the vehicle is washed according to a wash dictated by the carwash ticket.

Abstract: A carwash station receives a vehicle being conveyed in a direction of travel in a carwash having a ground pathway. The carwash station includes a frame supported by the ground pathway, a four-bar linkage attached to the frame and a side washing brush attached to the four-bar linkage and having an axis of rotation being perpendicular to the direction of travel and perpendicular to the ground pathway.

Abstract: An air blower assembly has a main housing with an air inlet opening and an air inlet housing is disposed around the air inlet opening and connected to the main housing. The air inlet housing defines an air inlet channel leading into the air inlet opening in the main housing. An air outlet channel is connected to the main housing, the air outlet is fluidically connected to the air inlet channel. A fan is disposed in the main housing for driving airflow through the air inlet channel to the air outlet. A silencer covers the air inlet housing and redirects air into the air inlet channel. The silencer controls the direction of air flow into the air inflow channel and noises generated by the fan assembly and the air flow stream are absorbed by a noise cancelling material and walls of the silencer.

Abstract: A wheel roller for a chain conveyor of an automated carwash has a more robust configuration due to a direction connection of the wheels to the carrier link. The wheel roller contains a carrier link forging having a main body with a carrier link formed as an unitary component, pins secured to the main body in a fixed, non-pivotable manner, and wheels attached to the pins.
