Whisper Wash Maxima 36" Surface Cleaner (3" Casters)
The Whisper Wash Maxima 36 Inch Surface Cleaner is a high-production commercial flat surface cleaner engineered for contractors who need increased surface coverage without stepping into oversized dual-swivel machines. Featuring a 36-inch aircraft-grade aluminum cover and four 3-inch pivoting casters, the Maxima delivers industrial cleaning power with smooth maneuverability.
Built with Whisper Wash’s signature machined and precision-balanced spray bar system, the Maxima eliminates zebra striping while delivering consistent, professional results across driveways, parking lots, sidewalks, pool decks, and other large flat surfaces. The heavy-duty nylon brush skirt helps contain overspray while improving safety and jobsite cleanliness.
The break-a-part aluminum handle collapses at the mid-section for easier transport and storage, making the Maxima a practical solution for mobile pressure washing operations. Designed for 6–12 GPM systems, this unit provides powerful, efficient flat surface cleaning backed by Whisper Wash’s proven rotary spray technology.

The optimized 1/2" internal diameter improves hydraulic flow while maintaining balanced operation, making it ideal for residential and light commercial flatwork applications where weight and maneuverability matter.
