Abstract

A self-propelled sweeper vehicle has a water recirculation system for water separated in a matter storage tank, which is re-injected into the suction nozzle or suction duct. Screens (212) for separating water from solid matter in the separation tank are rendered accessible for removal and cleaning purposes from outside the matter storage tank. For this purpose, a sealable opening (281, 283) and an associated closure are provided in the tank. The screens are removable, manually, through the opening for cleaning by back washing. <IMAGE>
