Westinghouse 16.5" Universal Surface Cleaner Attachment — 3400 PSI, 1/4" Quick-Connect, Lightweight 6 lb

The Westinghouse 16.5-inch Universal Surface Cleaner is a lightweight, durable attachment that converts most gas and electric pressure washers into a fast, consistent cleaner for patios, driveways, decks and walls.

This compact surface cleaner pairs a wide 16.5" cleaning path with a 3400 PSI rating and a 1/4" quick-connect fitting, making it simple to attach to most standard pressure washer wands. At roughly 6 pounds, the PWSC16.5 is easy to maneuver and store, yet engineered to remove ground-in dirt from flat and slightly vertical surfaces without the streaking or splashing that comes from using a single nozzle.

How quickly will it clean large flat areas?

The 16.5" diameter covers much more square footage per pass than a single spray nozzle, cutting cleaning time significantly on patios, garages and driveways. The dual-rotating internal booms create overlapping spray patterns for even coverage and a consistent finish.

• 16.5" cleaning path reduces passes compared with standard nozzles
• Up to 3400 PSI tackles stuck-on dirt and mildew
• Even spray pattern minimizes streaks and water splash

Will this fit my existing pressure washer?

The surface cleaner is built with a universal 1/4" quick-connect fitting to work with most gas and electric pressure washers that accept that standard connection. No specialized adapters are usually required, but you should confirm your pressure-washer’s quick-connect size before purchase.

• 1/4" quick-connect compatible with common pressure-washer wands
• Designed for both gas and electric models rated up to 3400 PSI
• Light 6-pound design for easy handling and attachment swapping

What surfaces can I safely clean with it?

This tool is intended for flat and modestly vertical surfaces such as concrete, brick, wood decks, composite decking and siding. The concentrated yet consistent spray pattern helps remove grime while reducing the risk of gouging or surface damage that can occur with a narrow high-pressure nozzle.

• Concrete, pavers and driveways—removes oil residue and dirt
• Wood and composite decks—cleans without uneven etching when used correctly
• Brick, siding and garage floors—efficient for broad, even washdowns

How durable and dependable is the Westinghouse PWSC16.5?

Constructed for homeowner and light professional use, the attachment balances low weight with sturdy materials to withstand regular cleaning jobs. Westinghouse supports the product with a 180-day limited warranty, reflecting its long-standing reputation for dependable tools.

• Lightweight 6-pound build for portability and storage
• Rated to handle pressures up to 3400 PSI for heavy cleaning tasks
• Backed by a 180-day limited warranty from Westinghouse

Who is this for? The PWSC16.5 suits homeowners, rental property managers, landscapers and light-contracting professionals who need a fast, repeatable way to clean wide, flat surfaces without constant nozzle swapping. If you want to cut cleaning time, reduce splashback and get a uniform finish on patios, driveways, decks and siding with a pressure washer you already own, this Westinghouse surface cleaner is a practical, easy-to-use addition to your toolkit.
