KAKO undercarriage pressure washer attachment — 2-in-1 4000 PSI cleaning broom with 90° angled wand, 3 extension wands & casters

The KAKO 2-in-1 undercarriage pressure washer attachment is a heavy-duty cleaning broom system that reaches beneath vehicles and flat surfaces to remove road grime, oil, and loose debris up to 4000 PSI.

This attachment combines a wide water broom head with a 90° angled wand and two straight extension wands to make undercarriage and surface cleaning faster, safer, and more thorough. Built for hot and cold water use and fitted with 1/4" quick connectors, the kit is designed to work with most pressure washers in the 1500–4000 PSI range. It includes four spray nozzles and two casters on the broom head for steady, even coverage when moving across driveways, sidewalks, or under vehicles.

How does the KAKO undercarriage attachment reach tight spaces under vehicles?

The system uses a 90° angled wand combined with two 16-inch straight extension wands to extend reach and navigate frame rails, crossmembers, and trailer undersides without lying under the vehicle. The broom head sprays across a broad path to dislodge grime while keeping the operator at a safe distance.

• 90° elbow wand (14") for angled access
• Two 16" straight extension wands for additional reach
• Wide broom head with four nozzles for even spray coverage
• Two casters for stable, controlled movement

What pressure and water types work best with this pressure washer attachment?

The KAKO attachment tolerates 1500–4000 PSI; for deeper cleaning and oil removal we recommend 2500 PSI or higher. It is rated for both hot and cold water, so it can pair with heated washer systems when available for improved grease and oil softening.

• Safe operating range: 1500–4000 PSI
• Recommended for thorough cleaning: ≥2500 PSI
• Compatible with hot or cold water systems
• 1/4" quick-connect fittings for rapid setup

Which surfaces and messes is this cleaner most effective on?

Designed for undercarriages but versatile enough for flat surfaces, the broom removes loose debris like leaves and sand from driveways and decks and tackles road grime and light oil buildup beneath cars, trucks, SUVs, and trailers. The rotating casters and broad spray pattern help cover large areas quickly with consistent results.

• Vehicle undercarriages: oil, mud, road film
• Driveways and sidewalks: sand, leaves, loose soil
• Trailers and commercial vehicles: grime removal along frame
• Decks and patios: surface-level debris clearing

How quick is setup and are replacement parts available?

Setup is straightforward: attach the 90° elbow to the broom head, add the straight wand extensions as needed, and snap in the 1/4" quick-connect plug to your pressure washer. All connections are designed to minimize leaks and the manufacturer offers a 6-month quality assurance policy with responsive customer service.

• Simple 1/4" quick-connect assembly
• No-tools-required attachment of wands and casters
• Built for durable, leak-resistant connections
• 6-month quality coverage and 24-hour customer response

Who is this for: The KAKO 2-in-1 undercarriage pressure washer attachment suits professional detailers, fleet maintenance teams, mechanics, and homeowners who need a safe, efficient way to clean beneath vehicles and large flat surfaces. If you regularly remove road grime, oil stains, or seasonal debris and want a tool that extends reach, reduces manual scraping, and speeds up washing tasks, this kit is a practical addition to a medium- to high-pressure washer setup.
