Westinghouse 16.5 in Pressure Washer Surface Cleaner - Pro Results

Our review of the Westinghouse 16.5 in stainless steel surface cleaner finds it best suited for homeowners and light pros who need a fast, reliable way to clean large flat areas. The single biggest reason to buy is the combination of a wide 16.5 in cleaning path and a 4400 PSI rating, which together cut cleaning time dramatically on decks, patios and driveways while delivering consistent results that conventional spray wands struggle to match.

Key Features

• 16.5 in cleaning width: Covers more surface with each pass so large patios and driveways take far less time to clean than with a wand.
• Up to 4400 PSI: High pressure capability removes stuck-on dirt, mold and mildew from brick, concrete and wood without multiple passes.
• 1/4 in quick-connect fitting: Lets users switch quickly between the surface cleaner and other pressure washer attachments for versatile jobsite use.
• Stainless steel construction: Durable metal housing stands up to routine outdoor use and resists corrosion for longer service life.
• Lightweight and maneuverable: Wheels and a compact design make it easy for one person to roll across flat surfaces and reach both horizontal and vertical areas.
• 180-day limited warranty: Provides short-term coverage and peace of mind from a long-established brand.

Who It's For

This attachment is ideal for homeowners, landscape contractors and property managers who need efficient cleaning of large, flat surfaces such as patios, driveways, sidewalks and decks. It is a practical pick for anyone already using a gas or electric pressure washer and who wants to cut labor time while improving consistency.

It is less appropriate for precision work on delicate materials or tight corners where a narrow wand is required, and those needing commercial heavyduty continuous use equipment may prefer a model designed specifically for highhour professional fleets.
