The Biffs Pathfinders spray cleaning system distributed by Satellite Industries is designed to clean and disinfect portable restrooms without the use of brushes, buckets and wipe-down towels. The enclosed aluminum unit has a 1,250 psi power-wash pump with auto shut-off, 4-gallon disinfectant reservoir with adjustable flow rate and dual spray guns. One gun operates at 5 gpm for charging the tank while the other functions as a high-pressure sprayer for cleaning or low-pressure sprayer for applying disinfectant. A twist of the wand handle switches the unit from power-wash to disinfection mode. Once the restroom is disinfected, the technician can change the nozzle and refill the waste-holding tank. 612/221-1100; www.biffspathfinders.com.
