DP-SPW1115 18-Inch Surface Cleaner for Shopping Centers and Two-Car Driveways

The DP-SPW1115 spins an 18-inch stainless steel disc rated to 4350 PSI, a path that covers more per pass than a 15-inch head and clears a standard two-car driveway in fewer runs. Dual rotating nozzles hold an even spray across the arc so concrete, asphalt, and paving stone come out without streaks. Four 360-degree casters roll the head smoothly across flat surfaces, cutting the push force on long cleaning sessions.

DP-SPW1115 Coverage and Connection

  • 18-inch cleaning disc — covers large driveways and commercial pads in fewer passes than a narrower head.
  • 4350 PSI rated pressure — accepts high-output commercial and prosumer gas pressure washers; run it at 2500 PSI or higher.
  • Dual rotating nozzles — even pressure across the 18-inch arc eliminates streak lines.
  • Two hose adapters plus 3/8" QC inlet — M22 and quick-connect fittings match most pressure washer brands with no extra parts.
  • Four 360-degree casters — maintain steady nozzle standoff and steer around obstacles.
  • Splash-free skirt — a circular brush contains overspray and debris around the head.
  • Stainless steel construction — resists corrosion under repeated daily use.

DP-SPW1115 Applications and Environments

Pressure washing contractors run the DP-SPW1115 on residential driveway routes where the 18-inch path clears a two-car driveway in half the passes a 15-inch model takes. Commercial property maintenance teams use it on shopping center walkways, restaurant exterior pads, and bank drive-through lanes scheduled for monthly cleaning. Building service contractors clean parking garage floors and loading dock aprons with the wider path during facility turnaround windows. Homeowners with large concrete driveways and expansive patios use it to shorten cleaning sessions that a bare wand drags out. The splash-free skirt keeps overspray off adjacent storefronts and parked vehicles on occupied commercial sites, and matching the unit to a machine at or above 2500 PSI keeps the nozzles turning at full speed across the width.

Frequently Asked Questions

What is the advantage of 2 hose adapters over a single fitting?
The 2 included adapters allow connection to pressure washers with different outlet fitting sizes — typically M22 and 3/8-inch quick-connect are the two most common configurations. Without adapters, you may need a separate adapter purchased from a hardware store.
How does 18 inches compare to the 15-inch DP-SPW1114?
The 18-inch path covers 44% more surface area per pass than a 15-inch cleaner (18² vs 15² in terms of proportional coverage). On a 400-sq-ft driveway, this reduces pass count from approximately 27 to 22 — noticeable time savings on repeated cleaning jobs.
What minimum GPM does the DP-SPW1115 require?
Rotating surface cleaners require minimum flow to spin the nozzle bar effectively. Contact us or review the product spec sheet for the exact minimum GPM requirement. Most 18-inch cleaners require at least 2.5 GPM for consistent nozzle rotation and streak-free coverage.
Is 4350 PSI too aggressive for residential concrete?
4350 PSI is the maximum rating — not the required operating pressure. Use the pressure washer's unloader valve to reduce working pressure to 2500–3000 PSI for standard residential concrete cleaning. Higher PSI is useful for heavy oil stains, mold, and traffic soils on commercial surfaces.
Can the DP-SPW1115 clean around obstacles like drain grates and expansion joints?
The circular footprint of an 18-inch surface cleaner requires manual wand work around drain grates, post bases, and expansion joint edges. Plan to finish corners and obstacles with a standard wand after the surface cleaner pass.
How should I maintain the rotating nozzle assembly?
Flush the nozzle assembly with clean water after each use to prevent mineral and detergent buildup in the nozzle orifices. Inspect nozzle tips for wear or clogging — worn nozzles produce uneven spray patterns that cause streak lines on cleaned surfaces.
Does this surface cleaner work with hot water pressure washers?
Contact us to confirm the DP-SPW1115's hot water temperature rating. Most polymer-housing surface cleaners are rated for cold water use only. Some commercial-grade models handle up to 140°F–160°F. Using a hot water washer beyond the cleaner's rated temperature will damage internal seals.
