Whisper Wash Big Hippo 8-Foot Surface Cleaner – Quad Swivel, 4 Spray Bars
The Whisper Wash Big Hippo 8-Foot Surface Cleaner is the largest and most powerful machine in the Hippo Series, engineered for extreme high-production commercial and municipal flat surface cleaning. With a massive 99" x 27" cleaning footprint and a quad-swivel, four spray bar configuration, the Big Hippo replaces multiple operators and machines with one ultra-efficient production system.
Built from powder-coated aircraft-grade aluminum and surrounded by a heavy-duty 1-inch nylon brush, the Big Hippo contains overspray while delivering uniform, edge-to-edge cleaning performance across a full 8-foot path. The quad swivel system dramatically increases rotational efficiency and water distribution, making it ideal for high-flow 16–32 GPM systems and modifiable up to 48 GPM for specialized industrial applications.
Designed for large-scale commercial contracts, warehouse complexes, airports, stadiums, industrial facilities, and municipal infrastructure, the Big Hippo is built to reduce labor hours while maximizing cleaning productivity.
When your jobs are measured in acres, not square footage — this is the tool built for the task.
