Westinghouse 15" Pressure Washer Surface Cleaner Attachment — 1/4" Quick-Connect, 3400 PSI, Enclosed Dual-Arm

The Westinghouse 15" Pressure Washer Surface Cleaner Attachment is a lightweight, heavy-duty tool that cleans large flat surfaces quickly, safely handling up to 3400 PSI with a 1/4" quick-connect for most gas and electric washers.

This 15-inch surface cleaner from Westinghouse is made to speed up cleaning tasks on decks, driveways, patios, walls and other broad, flat areas. It pairs with pressure washers that use a 1/4" quick connection and balances high cleaning power (rated up to 3400 PSI) with a compact, easy-to-store design. Weighing about 4 lb, the attachment helps reduce operator fatigue compared with handheld nozzles, while its enclosed spray arm reduces splashback and delivers a uniform finish.

How does the 15" surface cleaner improve cleaning speed and consistency?

The rotating dual-arm design covers a wide 15-inch swath, cutting the time required to clean large areas versus single-nozzle spraying. Its enclosed housing contains overspray and distributes pressure evenly so surfaces are cleaned uniformly without streaks.

• 15-inch cleaning path for faster coverage of flat surfaces
• Enclosed deck reduces splashback and mess
• Dual rotating arms provide consistent, streak-free results

Is this attachment compatible with my pressure washer and what PSI range does it need?

Westinghouse designed this surface cleaner for broad compatibility: it connects via a 1/4" quick-connect fitting common on many gas and electric washers. The unit performs best between 2500 PSI and 3400 PSI, so it is suitable for most medium- to high-pressure residential and light-commercial machines.

• 1/4" quick-connect fits most consumer and professional wands
• Effective performance rated for 2500–3400 PSI
• No adapters required for many standard setups

Will it damage surfaces like wood, brick, or concrete?

The cleaner concentrates pressure across a rotating arm, which cleans efficiently without the pinpoint force of a single nozzle. That spread reduces the risk of etching or gouging when you use appropriate pressure and stand-off distance for the surface material.

• Even pressure distribution reduces concentrated damage risk
• Suitable for concrete, brick, wood, pavers and siding when used correctly
• Adjust pressure and maintain distance to protect delicate finishes

How easy is it to store, maintain, and use this attachment?

The Westinghouse surface cleaner is lightweight and compact for simple storage in a garage or truck. Its plug-and-play quick-connect setup gets you cleaning fast, and routine rinsing after use keeps the spray arms and housing performing well season after season.

• Weighs approximately 4 lb for easy handling and transport
• Quick-connect design allows fast attachment and removal
• Rinse after use to prevent buildup and extend service life

Who is this for: The Westinghouse 15" surface cleaner is aimed at homeowners, property managers, and small contractors who need a reliable, fast way to clean medium to large flat surfaces without investing in a full-sized commercial unit. If you own a pressure washer with a 1/4" quick-connect and often tackle patios, driveways, decks or exterior walls, this attachment speeds work and delivers a more professional finish while staying compact enough for easy storage and transport.

Included features: 15" cleaning diameter, up to 3400 PSI rating, 1/4" quick-connect compatibility, lightweight 4 lb construction and a 180-day Westinghouse customer warranty for peace of mind. Use recommended pressure settings and safe operator practices to get the best, longest-lasting results.
