Surface maintenance vehicle with self-cleaning reservoir that captures hose runoff

摘要

Certain embodiments include a fluid recovery system. The fluid recovery system includes a vacuum system that applies a suction force on fluids on the floor surface to draw fluids to a fluid recovery tank. A reservoir is operably coupled to a recovery hose. The reservoir includes an inlet passage, an outlet passage leading to the recovery hose, and a fluid trap portion positioned between the inlet and outlet passages. The reservoir permits passage therethrough of fluids suctioned by the vacuum system from the floor to the recovery hose, and traps a backflow of fluids from the recovery hose in the fluid trap portion when the vacuum system stops suctioning fluids from the floor to the recovery hose. The reservoir is shaped to be generally self-cleaning and clears most fluids trapped in the fluid trap portion when the vacuum system starts suctioning fluids from the floor to the recovery hose.
