Cleaning under a vehicle with a pressure washer is usually awkward, messy, and uncomfortable. Most people either crouch down with a spray wand or try to angle the nozzle blindly beneath the car, hoping to rinse away mud and grime without soaking themselves in the process.
RYOBI’s 11-inch Water Broom is designed to make that job much easier.
Instead of using a single narrow spray stream, this attachment connects to a compatible pressure washer wand and spreads the water through three high-pressure jets at once. The result is a much wider cleaning path that can rinse larger areas more quickly while also reaching places that are normally difficult to access.
The attachment is marketed for driveways, patios, decks, garage floors, sidewalks, and vehicle undercarriages. But it’s the under-car cleaning capability that has been drawing the most attention online lately, especially in videos showing the tool sliding beneath vehicles while blasting away dirt and debris.
The Water Broom features an 11-inch cleaning width, helping users cover more surface area in a single pass compared to a standard pressure washer nozzle. Rather than slowly sweeping a thin jet back and forth, the attachment creates a broader spray pattern that can speed up routine cleaning jobs around the house.
RYOBI also includes a two-position pivot head that allows users to adjust the spray angle depending on the surface or the clearance underneath a vehicle. That flexibility can help when trying to clean lower areas without having to crawl on the ground.
The attachment is compatible with gas, electric, and cordless pressure washers rated up to 3,300 PSI. It uses a quick-connect coupler system, allowing it to attach to compatible pressure washer wands without additional tools.
At around 2.31 pounds (1.05 kg), the accessory is relatively lightweight considering its wide spray head and multi-nozzle setup. Since it relies entirely on the pressure washer’s existing pump and water pressure, there’s no motor or separate power source built into the attachment itself.
While it may look somewhat similar to a surface cleaner attachment, the Water Broom is a simpler and more compact design. Traditional surface cleaners typically use spinning spray bars enclosed inside a circular housing. The Water Broom instead keeps the spray jets exposed, making it easier to maneuver into tight spaces such as beneath vehicles or along edges.
It’s also aimed more at convenience and speed than precision detailing. For example, users cleaning heavily stained concrete may still prefer a dedicated surface cleaner for perfectly even results. But for general dirt, mud, leaves, salt buildup, and everyday grime, the broader spray coverage can significantly reduce cleaning time.
Customer reviews online frequently mention faster driveway cleaning and easier undercarriage washing as major advantages. Many users also like the fact that the attachment allows them to stand upright instead of crouching or crawling while cleaning hard-to-reach areas.
The RYOBI 11-inch Water Broom is currently listed on Amazon for about $54.97, although pricing may vary depending on availability and promotions.
For pressure washer owners looking for a faster way to clean flat surfaces — especially underneath vehicles — this attachment offers a relatively simple solution that focuses more on practicality than flashy features.
