Overview
The Whisper Wash Big Guy 28 (part WW2800-HFAL) is a 28-inch flat surface cleaner rated for 2,000–4,000 PSI and 5–12 GPM, running hot or cold water up to 212°F. Its aircraft-grade aluminum housing keeps operating weight to 38 lbs, and the signature Whisper Wash balanced, machined 2-nozzle rotary spray bar — installed with two #3 meg nozzles at 40 degrees — spins up to 2,500 RPM for even coverage across the wide 28" deck. Pivoting wheels with flat-free hard rubber tires and a heavy-duty nylon brush skirt make it easy to steer through large areas while containing the pressurized spray. It's built for contractors cleaning big flatwork — parking lots, drive lanes, warehouse floors — with higher-flow machines.
