Abstract
A cleaning system includes a vehicle with a drive subsystem comprising a fluid-powered drive motor drivingly connected to a pair of drive wheels. A brush/air jet boom assembly is removably mounted on the vehicle and includes a fluid-powered brush subassembly drivingly connected to a brush including a plurality of radially-extending flexible line segments. The brush/air jet boom assembly also includes an air jet subassembly with inboard and outboard nozzles. A spray boom assembly is mountable on the vehicle interchangeably with the brush/air jet boom assembly and includes a spray head for spraying a liquid spray material. A cleaning method includes the steps of providing compressed air and liquid spray material sources; pneumatically coupling a vehicle to the compressed air source; advancing the vehicle by pneumatically driving drive wheels thereof; pneumatically driving a rotating brush subassembly; brushing an object to be cleaned; pneumatically sweeping the object to be cleaned; interchanging a spray boom assembly with a brush/air jet assembly; coupling the spray boom assembly to the compressed air and liquid spray material sources; and pneumatically spraying the liquid spray mat…
