A central vacuum system with several suction hoses provided with a suction nozzle which, after having vacuumed with the suction hose concerned, must be placed in a suction nozzle holder and which, before vacuuming with the suction hose concerned, must be taken out of the suction nozzle holder. The central vacuum system includes a detection system for detecting whether a suction nozzle is either or not placed in its corresponding suction nozzle holder, as well as a control unit which is connected to the detection system. The control unit controls the suction force of the central pump installation as a function of the number of suction hoses being used.

A vehicle wash system includes a track system positioned above a wash area and a movable body coupled to the track system. The movable body is movable along at least two axes and includes a gripping mechanism to selectively hold and release one or more wash tools.

A portable car-cleaning device, which comprises a cleaning brush and at least one water storage chamber with a water inlet, the at least one chamber being provided with at least one washing dewatering device that includes two oppositely disposed rollers, the cleaning brush being interposed between the two rollers for washing and dewatering. The car-cleaning device is simple in structure and convenient to carry, and convenient in washing and dewatering the cleaning brush, making a car washed faster, improving the washing efficiency.

A vehicle wash component for a vehicle wash system, including a frame portion and an air delivery portion disposed on the air delivery portion. The air delivery portion is configured to emit high velocity air onto a vehicle exterior. A fluid delivery portion is disposed on the frame portion. The fluid delivery portion is configured to emit high pressure fluid onto the vehicle exterior. The fluid delivery portion is disposed rearward from the air delivery portion with respect to a direction of travel of a vehicle. The air delivery portion and the fluid delivery portion are configured to emit the high velocity air and the high pressure fluid onto the vehicle exterior simultaneously.

Laser cleaning equipment and a cleaning method for a shaft component are provided. The equipment includes: a supporting base assembly; two driving wheel structures on the supporting base assembly, driving wheels of each of which is configured for being close to or away from each other, and the shaft component to be cleaned is placed between the two driving wheel structures; a friction wheel structure that is tangent to driving wheel structure(s) and uses a friction force thereof to drive driving wheel structure(s) to rotate; a connection shaft assembly that coaxially passes through the friction wheel structure; a power driving mechanism, one end of which that faces toward the connection shaft assembly is in drive connection with the connection shaft assembly and is configured to drive the connection shaft assembly to rotate; and a laser cleaning mechanism configured for performing laser cleaning on the shaft component to be cleaned.

The invention relates to a device for automatic dispensing of a maintenance agent, such as an anti-icing agent or a de-icing agent, on specific parts of a rolling stock travelling on a railway track. The device comprises a dispensing unit, a detection unit configured to generate a detection signal before said rolling stock reaches the dispensing unit, a sensor unit configured to determine position and velocity of the rolling stock, and a control unit. The control unit is configured to receive said detection signal from said detection unit, determine a dispensing schedule based on said rolling-stock velocity, and transmit a control signal to the dispensing unit to control said dispensing unit based on said dispensing schedule. Furthermore, the present inventive concept also relates to an associated method.

A modular mobile vehicle washing and servicing facility for washing, vacuuming, and performing other vehicle servicing functions. The modular facility includes automated car wash equipment housed in mobile containers designed for easy transport and quick set up to serve as a functionally and visually integrated facility. The facility includes a car wash bay housing the car wash equipment and first and second bay modules positioned adjacent the car wash bay and housing additional equipment to support the washing features of the car wash bay. A canopy extends over the car wash bay to provide cover and protect the car wash equipment.
