DUSICHIN 16-Inch Undercarriage Washer Pressure-Washer Attachment — 4 Nozzles, 4 Extension Wands

The DUSICHIN 16-inch Undercarriage Cleaner is a pressure-washer attachment that sprays four high-pressure jets to remove grime from vehicle underbodies and to act as a wide water broom for sweeping hard surfaces.

Built to attach quickly to most gas and electric pressure washers, this DUSICHIN undercarriage washer combines a broad 16-inch spray head, four quick-connect nozzles and multiple extension wands so you can reach under cars, trucks, RVs and trailers without crawling underneath. It also doubles as a water broom for driveways, garage floors and patios, helping you blast away oil, salt, mud and road muck while protecting chassis components by removing corrosive buildup.

How does this attachment reach and clean undercars without crawling underneath?

The kit includes a 16-inch head plus a set of straight and curved extension wands that let you push the spray head beneath the vehicle from standing position. Durable rollers on the head keep the nozzle assembly moving smoothly while the curved wand directs spray deep into recesses.

• 16-inch head with four high-pressure nozzles for broad coverage
• Four extension wands: three 14" straight and one 10.5" curved flexible wand
• Durable wheel rollers for stable, guided movement under vehicles
• 1/4" quick couplings for fast tool swaps and secure connections

What surfaces and soils is the DUSICHIN undercarriage washer best suited for?

This attachment is designed to remove road grime such as mud, salt deposits, oil residues and fuel film from chassis and trailer underbodies. When used as a water broom, it efficiently clears loose debris and rinses hard flat surfaces like concrete, asphalt and paver patios.

• Vehicle chassis, tow hitches, frame rails and trailer underbodies
• Garage floors, driveways, sidewalks and loading ramps
• Removes salt, mud, oil stains and accumulated road debris
• Works with garden hose adapter for low-pressure rinsing when needed

Is it compatible with my pressure washer and how do I install it?

The DUSICHIN undercarriage cleaner is built for compatibility: every fitting uses 1/4" quick couplings and it supports up to 4000 PSI maximum pressure. Installation is tool-free in most cases — attach the quick-connect coupler to your pressure washer lance or use the included garden-hose adapter for gentler rinses.

• Maximum rated pressure: 4000 PSI (check your washer specs)
• 1/4" quick couplings on all parts for rapid assembly
• Includes garden hose adapter for basic water-supply setups
• Patent-backed wand storage system keeps extensions organized

How does this tool protect vehicle undercarriages and simplify cleanup?

Regularly removing corrosive deposits like road salt and oil extends component life by reducing rust and deterioration. The wide spray pattern and ergonomic wand design speed up cleaning tasks, requiring fewer passes and minimizing time spent crouched or beneath vehicles.

• Removes corrosive salt and grime to help reduce rust formation
• Ergonomic extensions and rollers make underbody passes faster
• Wide 16" spray reduces the number of passes needed
• Simplifies large-area rinsing when used as a water broom

Who is this for: The DUSICHIN 16" Undercarriage Cleaner suits DIYers, detail shops, fleet managers and RV owners who need a safer, faster way to clean underbodies and large hard surfaces. If you regularly remove road salt, oil or heavy mud from vehicles or maintain concrete and asphalt areas, this attachment reduces manual scraping, improves cleaning efficiency and helps protect metal chassis components from corrosive buildup.
