Westinghouse 16.5" Stainless Steel Surface Cleaner Attachment — 4400 PSI, 1/4" Quick-Connect for Driveways & Decks

The Westinghouse 16.5-inch stainless steel surface cleaner is a heavy-duty attachment that turns a pressure washer into a fast, even cleaner for large flat surfaces up to 4400 PSI.

Whether you’re refreshing a driveway, deck, sidewalk, or exterior wall, this accessory delivers a wide cleaning path that reduces streaking and cuts job time. Built from stainless steel for durability and designed to fit common 1/4" quick-connect pressure washer wands, it works with many gas and electric units. The tool balances power and control so homeowners and contractors can remove dirt, algae, and grime more efficiently than using a lance alone.

How does this attachment improve cleaning speed and uniformity?

Instead of moving a single rotating nozzle over a surface, the dual-rotor head inside the 16.5" housing provides two overlapping spray patterns that cover a broad swath in each pass. That reduces the number of passes required and minimizes the banding or striping common with single-nozzle use. The enclosed housing contains the spray for cleaner runoff control.

• 16.5" cleaning diameter covers more ground per pass
• Dual rotating jets deliver even, overlapping spray
• Enclosed skirt reduces overspray and splashback

What pressure and connector requirements should I check before buying?

The attachment is rated to handle pressures up to 4400 PSI, so verify your washer’s maximum operating pressure stays within that limit. It features a 1/4" quick-connect fitting that works with the most common pressure washer couplers, allowing quick hookup and simple swaps between tools.

• Maximum rated pressure: 4400 PSI
• Standard 1/4" quick-connect for widespread compatibility
• Suitable for many gas and electric pressure washers when fittings match

Is the construction durable and easy to maintain?

Engineered with stainless steel components for corrosion resistance, this surface cleaner is built to withstand frequent use and exposure to water and detergents. The straightforward design makes it easy to access rotating arms and nozzles for inspection and cleaning so performance stays consistent season after season.

• Stainless steel housing resists rust and wear
• Serviceable spray arms and nozzles for simple upkeep
• Lightweight enough for handheld maneuvering yet rugged for jobsite use

What surfaces and tasks is this best suited for?

This tool excels on large, flat expanses where speed and even cleaning matter most: driveways, patios, concrete floors, wooden decks, and exterior siding. It performs well for removing built-up dirt, mildew, and environmental staining without the streaking of individual nozzles when used properly.

• Concrete driveways and sidewalks
• Wooden and composite decks and porches
• Brick, pavers, garage floors, and exterior walls

Who is this for? The Westinghouse 16.5" surface cleaner is intended for homeowners who want faster, more consistent results than a standard wand, as well as professionals who need an efficient attachment for repeated large-area cleaning. If you own a pressure washer that matches the 1/4" quick-connect and operates at or below 4400 PSI, this accessory adds productivity, reduces user fatigue, and helps achieve a uniform finish across horizontal and vertical flat surfaces. Backed by Westinghouse's 180-day warranty, it’s a practical add-on for anyone looking to upgrade their cleaning toolkit without adding complicated installation or maintenance steps.
