MYPIN 16" Undercarriage Water Broom — 2-in-1 4000 PSI Washer Attachment with Foam Bottle and Stainless Wheels

This versatile 16-inch water broom combines an undercarriage cleaning wand with an optional foam sprayer so you can quickly remove mud, salt, road film and sticky residue from car undersides, garage floors, ramps and other low-clearance surfaces. Crafted from stainless steel and aluminum alloy, the tool attaches to standard 1/4” quick-connect pressure washer wands and wheels across the unit let you roll it smoothly beneath vehicles for a fast, even clean.

How does the MYPIN undercarriage broom reach tight spaces under vehicles?

The wand assembles into a low-profile 16" head with three stainless steel extension pipes that create a slim, stable frame. Movable wheels hold the broom at a consistent height so the spray reaches the underbody without scraping.

• 16-inch bar spans undercarriages for broad coverage
• Low-profile design fits cars with limited ground clearance
• Three stainless steel pipes provide rigid support and easy assembly
• Durable wheels allow steady rolling beneath vehicles

Can I switch from foam cleaning to high-pressure rinse?

Yes. The MYPIN 2-in-1 includes a foam bottle and replaceable foam nozzle for detergent application, plus multiple washing nozzles for a high-pressure rinse. Swap nozzles quickly to foam, then rinse away loosened dirt for a complete two-step clean.

• Foam nozzle and bottle attach to apply cleaner evenly
• Four foam nozzles for varying foam density and coverage
• Four washing nozzles for targeted high-pressure rinsing
• Simple nozzle changes let you alternate tasks on the fly

What pressure and connector type does this work with?

The broom is built to be used with pressure washers rated between 1200 and 4000 PSI. It uses a 1/4” quick-connect fitting—confirm your pressure washer’s connector size before purchase to ensure compatibility.

• Compatible with 1200–4000 PSI machines (washer unit not included)
• Designed for 1/4” quick-connect hose fittings only
• Heavy-duty materials withstand high-pressure water flow
• Not universal—check connector size before ordering

How durable is the MYPIN water broom and how easy is it to maintain?

Constructed from stainless steel and aluminum alloy, this tool resists corrosion and handles repeated high-pressure use. The plastic wheels are reinforced to roll smoothly without cracking, and the simple pipe assembly makes rinsing and storage straightforward.

• Stainless steel and aluminum alloy for longevity
• Rugged plastic wheels engineered to resist breakage
• Quick-disconnect pipes make cleaning and storage easy
• Replaceable nozzles keep performance consistent over time

Who this is for: The MYPIN 2-in-1 16” Undercarriage Water Broom is ideal for car owners, detailers, fleet managers and homeowners who need a fast, efficient way to clean undercarriages, garage floors and driveways without crawling beneath vehicles. If you already own a compatible 1/4” quick-connect pressure washer (1200–4000 PSI) and want to speed up routine heavy-duty cleaning while using foam detergents and high-pressure rinses, this attachment saves time and improves results.
