Abstract: A vehicle mountable system for cleaning trash receptacles with wash-water. The system includes an enclosure with an access opening, supported on the vehicle, and a carriage disposed within the enclosure. A spray head is aligned to impinge wash-water against the trash receptacle while it is engaged with the carriage. A basin is aligned to accumulate wash-water drainage from the spraying operation. A spray shield is operated to a closed position that reduces wash-water effluence from the enclosure. The system may include a filter and means for sanitizing wash-water that is accumulated by the basin and recirculated through a holding tank. An automated arm engages a trash receptacle to engage and disengage the trash receptacle with the carriage through the access opening in the enclosure. Plural trash receptacles can be engaged with the carriage and advanced through plural positions within the enclosure.
