Protect Your Investment. Clean What You Can’t See.

Every vehicle owner knows how important it is to keep the exterior clean—but what about the parts you don’t see? The 16” Under Car Pressure Washer Water Broom is designed to help you clean one of the most neglected and corrosion-prone parts of your vehicle: the undercarriage. From winter road salt and coastal grime to mud, dirt, and debris, this powerful cleaning tool helps you remove buildup that leads to rust, decay, and costly repairs.

Compact and easy to use, this undercarriage cleaner connects to your pressure washer as an attachment and slides effortlessly beneath cars, trucks, SUVs, trailers, and even off-road equipment. Its 16-inch spray bar is outfitted with multiple high-pressure nozzles that deliver a powerful fan spray, evenly blasting away grime from the underside of your vehicle in one efficient pass.

If you live in a region with harsh winters, drive through muddy trails, or just want to keep your vehicle in peak condition, this water broom is the tool your garage is missing.

Why Undercarriage Cleaning Matters

While regular washing keeps your paint shining and windows clear, the underside of your vehicle is where real damage can happen if ignored. Road salt, mud, slush, sand, and oil all accumulate beneath your car—especially during winter or after off-road adventures. Left unchecked, this grime causes rust, corrodes brake lines, and damages suspension components.

That’s where the 16” Under Car Pressure Washer Water Broom comes in. It makes professional-quality underbody cleaning accessible right in your driveway or garage—saving you time, money, and vehicle wear over the long haul. This powerful cleaning tool helps you remove buildup with ease, preventing rust, decay, and costly repairs.

Easy Operation with Maximum Coverage

Equipped with a 16-inch spray bar and multiple high-pressure nozzles, this water broom delivers a wide, even cleaning path beneath your vehicle. It connects to your pressure washer using a standard 1/4” quick connect fitting, allowing you to hook it up in seconds and get to work immediately.

Simply attach the product to your spray wand or extension lance, roll it underneath the vehicle, and activate the water flow. The nozzles will fire powerful, fan-shaped jets upward to blast away gunk from your chassis, axles, wheel wells, and underbody panels.

No crawling. No jacks. No lifting. Just push and clean.

Low Profile for Tight Spaces

Designed to fit where you can’t, this water broom’s low-profile frame and compact wheels allow it to glide under most vehicles without needing ramps or lifts. With just a few inches of clearance required, it easily reaches areas that are often overlooked, including:

  • Exhaust systems

  • Brake and fuel lines

  • Suspension components

  • Chassis rails and crossmembers

  • Transmission housing

  • Underside of bumpers and wheel wells

It’s the easiest way to add thorough, preventive maintenance to your car care routine.

Frequently Asked Questions about Pressure Washers

How to store a pressure washer?

To ensure the durability of your heavy duty pressure washer:

  • Empty the gas tank to prevent fuel from degrading or clogging the engine.
  • Empty the pump and hoses of any remaining water.
  • Perform necessary maintenance before storage.
  • Store in a dry area.
  • Cover.

What is a pressure washer?

A power washer is a cleaning machine that uses a gasoline engine to power a high pressure water pump and nozzle. It’s used to clean driveways, decks, vehicles, outdoor furniture and more by spraying water at high PSI to remove dirt, grime, mold and other debris.Many models also come with a detergent tank for added cleaning power.

How does a power washer work?

A power washer works by drawing water from a connected hose and pumping it through a high pressure nozzle. The gas engine powers the pump which pressurizes the water and then expels it through the nozzle at high speed to clean the surface. The water pressure is measured in PSI (pounds per square inch) and the flow rate is measured in GPM (gallons per minute).Many models also feature adjustable water pressure settings to cater to different cleaning needs. BE makes pressure washing easy with models available for light jobs and heavy duty commercial cleaning projects.

Gas vs Electric power washers?

The main difference is that a gas pressure washer, known for its cleaning power, is powered by a gasoline engine, making it more powerful and portable, while an electric pressure washer is powered by electricity and is generally quieter and lighter.

Gas pressure washers are for heavy duty and large areas due to their durability, whereas electric pressure washers are for smaller jobs.

Your BE electric pressure washer is perfect for smaller jobs and built for portability, and we offer a wide range of electric models. Included with our electric models is a long extension cord for use anywhere around your house.

What to consider?

When choosing a gas pressure washer consider:

  • Pressure (PSI): More PSI means more cleaning power but also more potential for damaging delicate surfaces.
  • Flow Rate (GPM): More GPM means faster cleaning as more water is dispensed.
  • Engine Power: Bigger engines mean more durability and power.
  • Portability: Weight, handle design and wheel size for easier to move.
  • Nozzles: Multiple spray nozzles to adjust the spray pattern for different tasks.
  • Adjustable Nozzle: Allows for fine-tuning the spray intensity and pattern for various cleaning needs.

How much pressure do I need for?

The required pressure (PSI) and cleaning power depend on the surface you’re cleaning:

  • Light duty (car washing, outdoor furniture): 1,300-1,800 PSI.
  • Medium duty (patios, fences, decks): 2,000-3,000 PSI.
  • Heavy duty (driveways, brick walls, large equipment): 3,000+ PSI.

Many pressure washers come with adjustable pressure settings to handle different cleaning tasks effectively.

Can a pressure washing damage surfaces?

Yes, a power washer can damage surfaces if used incorrectly. High pressure water can strip paint, dent soft surfaces or even cause structural damage if the pressure is too high or the nozzle is held too close to the surface. Always use the right PSI for the material you’re cleaning and keep a safe distance from delicate surfaces.

To prevent damage, consider using a model with adjustable pressure settings.

How to maintain your pressure washer?

To ensure the durability and smooth operation of a pressure washer:

  • Change the oil as per manufacturer’s instructions.
  • Clean or replace the air filter to ensure good airflow.
  • Inspect and clean the nozzle regularly to prevent clogs.
  • Drain the gas tank if you’re storing the washer for a long time.
  • Check the hoses for leaks or damage and replace them if needed.
  • Follow regular maintenance requirements to keep the washer in optimal condition.

Can I use a pressure washer in cold weather and low water temperature?

You can use a pressure washer in cold weather but it’s more difficult. The water flow rate in the hoses and pump can freeze and damage the equipment. If you plan to use your pressure washer in cold temperatures make sure to winterize it and store it in a warm area when not in use. You can also use anti-freeze solutions for pressure washers.

Some models are designed to use hot water, which can be particularly effective for cleaning in cold weather.

Do I need any accessories?
