A frame member is capable of connection to a lifting cable moving the frame relative to a surface to be cleaned. The carriage is supported on the frame member and is adjustable on tracks between sides of the frame members. A hose support is pivotally mounted on the frame member on a lateral axis and has an operator's handle for moving the carriage and pivoting the hose support. The hose support includes a clamp for multiple hoses for large area treatment. One or more of the hoses may be individually removed for operation independent of the multiple hose support. An auxiliary clamp for the hoses is provided to free up movement of the carriage. The operator's handle for the carriage has switches thereon for operation of the multiple hoses, at least one of the switches being removable for controlling operation of a single hose that has been removed from the carriage.
