Whisper Wash Big Guy 28″ Surface Cleaner (ww2800)

Whisper Wash Big Guy 28” – Heavy-Duty Surface Cleaner with Fixed Tires, Caster Control, and High-Performance Spray Bar Options

When large-scale cleaning demands powerful equipment and efficient handling, the Whisper Wash Big Guy 28” delivers exceptional results every time. Designed to cover more ground while maintaining full control, this unit is trusted by professionals working in stadiums, parking lots, driveways, and other expansive surfaces.

The 28” powder-coated aluminum cover is built from aircraft-grade materials, making it lightweight yet incredibly durable. A 4” front caster allows for smooth pivoting around tight spaces, while the two fixed 8” no-flat rear wheels on a steel axle provide balanced traction across open areas.

Its fixed handle design gives operators complete one-handed control, even during longer sessions. The molded trigger gun grip ensures comfort, while a quick-disconnect lever makes switching to spot cleaning quick and efficient.

Under the cover, the Whisper Wash signature swivel system powers a precision-machined and balanced spray bar, which rotates evenly at up to 2,500 RPM. This setup eliminates zebra striping while maintaining consistent flow and pressure. Whether using hot or cold water, the Big Guy is rated up to 212°F, supports 2,000–4,000 PSI, and works efficiently with 5–12 GPM.

Before shipping, you must specify nozzle sizes or list your pressure washer’s GPM and PSI in your order notes.

From Primitive to Precision: Whisper Wash Spray Bar Innovation

Whisper Wash started with crude, unstable spray bar assemblies made of elbows, tees, and pipes—designs still seen in low-end models today. They then engineered a single, precision-machined spray bar, followed by stainless steel sleeves that protect tips from wear.

Today, the evolution continues with the Hydro-Flow and XForce series, built for unmatched flow, balance, and longevity.
