Westinghouse 16" Pressure Washer Undercarriage Cleaner & Water Broom — 4,400 PSI, M22 1/4" Connector, Hot Water Ready

The Westinghouse PWUC 16" is a dual-function pressure washer attachment that cleans vehicle undercarriages and doubles as a wide water broom for driveways, delivering up to 4,400 PSI through four high-pressure nozzles.

Designed for owners who want to remove salt, oil, mud and grime from hard-to-reach underside components or quickly rinse flat surfaces, this 16-inch attachment connects to most gas and electric pressure washers. It uses M22 1/4" quick connectors, accepts both cold and hot water up to 194°F, and combines a curved extension wand with small wheels for comfortable, controlled use.

How does the attachment clean a vehicle's undercarriage?

The undercarriage mode directs pressurized jets upward to dislodge corrosive road salts, oil build-up and stuck dirt without crawling under the car. The curved wand and low-profile head let you reach beneath trucks, SUVs, trailers and motorcycles while staying safely on the ground.

• Four high-pressure nozzles delivering up to 4,400 PSI
• Curved extension wand reaches under vehicles without lifting
• Lightweight body with wheels for stable, hands-free motion

What makes it good for cleaning driveways and flat surfaces?

Switched to water broom mode, the PWUC 16" lays down even, wide streams that sweep away loose debris, mud and oil from concrete and pavers. The broad 16-inch head saves time compared with a single nozzle wand and reduces streaking for a more uniform finish.

• 16" coverage clears a wider swath per pass than single nozzles
• Four nozzles produce consistent pressure across the head
• Ergonomic handling helps maintain steady, efficient strokes

Will it fit my pressure washer and handle hot water?

The attachment uses standard M22 1/4" quick connectors that are compatible with most gas and electric pressure washers, making hookup straightforward. It tolerates hot water up to 194°F, which can help when loosening heavy grease and oil during surface cleaning.

• M22 1/4" quick connectors for broad compatibility
• Rated for hot water up to 194°F and cold-water operation
• Works with both gas and electric pressure washer units
