Simpson Cleaning 20ft Industrial Pressure Washer Surface Cleaner

In this review the SIMPSON 20' industrial surface cleaner is presented as a practical accessory for contractors and homeowners who regularly tackle large exterior surfaces. The bottom line: it is best for users who need quicker, more uniform cleaning than a wand can provide, because its 20' diameter and two high-pressure rotating jets deliver roughly 10x the coverage of a standard nozzle and cut job time on driveways, patios, and shop floors. The kit is straightforward to hook up via a 3/8-in quick connection and works with hot or cold machines within the specified pressure and flow range.

Key Features

• Universal 3/8-in QC: The quick connection gives a universal fit to most high-pressure hoses so setup is fast and tool changes are simple.
• Two rotating jets: Dual high-pressure rotating nozzles provide wide, streak-free coverage that reduces passes and speeds cleaning on large flat surfaces.
• 20' diameter: The large footprint delivers roughly 10x more coverage than a single nozzle, ideal for driveways, sidewalks and workshop floors.
• Durable construction: Powder-coated steel shroud, stainless steel nozzles and brass fittings resist corrosion and add longevity for frequent use.
• Overspray control: The shroud helps keep surrounding areas and the operator drier compared with a standard wand, reducing cleanup.
• Hot and cold compatible: Rated to 212F, it works with hot or cold pressure washers within the recommended PSI and GPM range.

Who It's For

The surface cleaner is a good fit for contractors, property managers and serious homeowners who regularly clean large flat areas and want to cut labor time: driveways, patios, decks and garage or shop floors benefit most from the wide 20' scrubber and rotating jets. It particularly suits gas-powered machines that meet the recommended minimum of 3450 PSI and about 2.3 GPM.

Those who should look elsewhere include users with lower-powered electric washers or machines under 3450 PSI, or anyone who needs a tool for tight corners and vertical surfaces, since the 20' diameter is optimized for open, flat areas rather than detail work.

Pros & Cons

Pros

• Greatly increases coverage and reduces cleaning time on large surfaces.
• Robust materials including powder-coated steel and stainless nozzles improve corrosion resistance.
• Easy to connect with the 3/8-in quick connection and compatible with hot or cold machines to 212F.

Cons

• Some users report mixed performance with the spin rate, with occasional stopping or inconsistent rotation under load.
• Requires a fairly powerful pressure washer (recommended min 3450 PSI), so it is not suitable for lower-powered electric units.

Our Verdict

The SIMPSON 20' industrial surface cleaner is a practical value for anyone with a compatible high-pressure washer who needs fast, consistent cleaning of large flat areas; its wide coverage and durable materials justify the purchase for frequent use. Buyers with lower-powered machines or who need fine-detail cleaning should consider other tools, but for driveways and commercial floors this unit saves time and delivers even results.
