Whisper Wash Mini Mondo Force 31" Surface Cleaner – Dual Swivel (3" Casters)
The Whisper Wash Mini Mondo Force 31 Inch Surface Cleaner is a high-production commercial rotary surface cleaner engineered for maximum efficiency on large-scale flatwork. Featuring a 31" x 16" cleaning footprint with dual swivels and dual spray bars, the Mini Mondo is designed to deliver the output typically requiring two machines and two operators.
Constructed with a powder-coated aircraft-grade aluminum housing and surrounded by a 1-inch heavy-duty nylon brush skirt, this unit helps contain overspray while maximizing cleaning force. Four 3-inch pivoting casters allow responsive, multi-directional maneuverability across expansive surfaces.
The dual-swivel system—each equipped with twin self-lubricating thrust bearings—drives two precision-balanced spray bars simultaneously, increasing cleaning efficiency by up to 33% compared to traditional single-swivel systems. Designed for pressure washers operating between 6–12 GPM (modifiable up to 20 GPM) and 2,000–4,000 PSI, the Mini Mondo is built for contractors handling large commercial properties, warehouses, parking structures, stadiums, and industrial facilities.
With its double-direction handle bracket, the Mini Mondo can be operated lengthwise in tighter areas by reversing the handle orientation, making it more versatile than its size suggests.
When production speed and wide coverage matter, the Mini Mondo Force delivers unmatched flat surface cleaning performance.
Hydro-Flow Aluminum 2-Tip Spray Bar:
Constructed with lightweight, precision-balanced aluminum ends, this standard Hydro-Flow configuration delivers smooth rotation and efficient cleaning performance. 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.
Dual Swivel System: Two signature Whisper Wash swivels increase cleaning efficiency up to 33% over single-swivel systems.
Dual Balanced Spray Bars: Precision-machined dual spray bars provide expanded surface coverage and consistent rotation.
31 x 16 Inch Cleaning Footprint: Wide coverage path reduces cleaning time on large flat surfaces.
Aircraft-Grade Aluminum Cover: Powder-coated housing built for industrial durability.
1-Inch Nylon Brush Skirt: Helps eliminate overspray and contain cleaning force beneath the unit.
Four 3-Inch Pivoting Casters: Allows smooth, multi-directional maneuverability.
Double-Direction Handle Bracket: Enables longways operation for tight or narrow spaces.
