Whisper Wash Maxima Professional 36″ Surface Cleaner (max3600)

Whisper Wash Maxima 36” – Heavy-Duty Surface Cleaner with Expanded Coverage, Pivoting Casters, and Premium Spray Bar Compatibility

When your job demands high-efficiency cleaning across large surfaces, the Whisper Wash Maxima 36” delivers unmatched power, control, and coverage. With a wide 36-inch powder-coated aluminum cover, this machine is built to dominate expansive areas with precision and speed.

Surrounding the cover, a 1” heavy-duty nylon brush keeps high-pressure spray confined to the surface—protecting the operator and the surroundings. Meanwhile, four 3” pivoting casters allow effortless movement in any direction, even around tight spaces or curved edges.

At the heart of the Maxima, Whisper Wash’s signature machined and balanced spray bar rotates smoothly to deliver consistent cleaning performance. Powered by the legendary Whisper Wash swivel, featuring twin self-lubricating thrust bearings, this system reduces vibration and eliminates zebra striping.

Additionally, the ergonomic break-apart handle is built from aircraft-grade aluminum and collapses easily for storage and transport. Its trigger gun control, fitted with a quick-connect system and safety grip, ensures confident and fatigue-free operation on long jobs.

This unit handles hot or cold water up to 212°F, works between 2,000–4,000 PSI, and supports a flow rate of 6–12 GPM, making it ideal for cleaning sidewalks, pool decks, garage floors, and more.

Whisper Wash Spray Bar Innovation

In the early days, spray bars were primitive and hard to balance. Threaded elbows and pipes made rotation unreliable. Whisper Wash changed that with a single-piece machined spray bar, later improving it by adding stainless steel tip sleeves for durability.

Now, the new Hydro-Flow and XForce spray bar systems offer advanced flow, control, and longevity—pushing surface cleaning to a whole new level.
