Whirl-A-Way Flat Surface Concrete Cleaner BE #2000WAWY

20" Whirl-A-Way Flat Surface Cleaner by BE Pressure

If you clean concrete for a living, you already know a wand is the slowest way to do it. The 20" Whirl-A-Way surface cleaner from BE Pressure is built to change that. Two high-speed rotating jets lay down a 20-inch cleaning path that covers driveways, sidewalks, parking lots, and warehouse floors up to 70% faster than a standard spray wand. No zebra stripes. No missed spots. Just an even, clean finish every pass.

This is one of the most popular surface cleaners in the pressure washing industry for a reason. It handles the work that pays the bills (driveways, pool decks, gas station pads, loading docks) and it does it all day without beating you up. The twin ergonomic handlebars and built-in trigger gun mean you can start and stop water flow without switching tools. The four swivel casters keep the cleaning head at the right height so pressure stays consistent across the whole path. And the nylon bristle skirt traps water and debris under the dome, so you are not spraying mud all over the garage door or your boots.

Who This Surface Cleaner Is For

The 20" Whirl-A-Way sits right in the sweet spot for most pressure washing contractors. It is big enough to cover ground fast on residential driveways and commercial sidewalks, but not so wide that it becomes hard to control around edges, curbs, and landscaping. If you run a machine between 3,000 and 4,000 PSI with at least 3.5 GPM, this cleaner will work hard for you.

Homeowners with a decent gas pressure washer will get great results too. If you have been cleaning your driveway with a 15-degree tip and wondering why it takes three hours and looks streaky, this tool is the answer. It turns a frustrating weekend chore into a 45-minute job.

Specifications

How It Works

A surface cleaner is basically a pressurized spinning mop. Water from your pressure washer feeds through the handle, into a swivel, and out through two nozzles mounted on a spray bar under the dome. That bar spins at high RPM, and the angled nozzles blast dirt off the surface in a circular pattern. Because both nozzles cover the full 20-inch diameter, you get even cleaning with no streaks.

The hover design is important too. The water pressure actually lifts the dome slightly off the surface, so the unit floats just above the concrete. This means it will not scratch or gouge aggregate, pavers, or stamped concrete the way dragging a heavy steel cleaner might. You guide it across the surface and the casters keep everything tracking straight.

Key Features Contractors Care About

Built-in trigger gun on the handle. This is a big deal. Most surface cleaners need a separate gun and wand to control water flow. The Whirl-A-Way puts the trigger right in the handle, so you pick it up and go. One less connection to leak, one less thing to carry.

Contractor-rated swivel. The swivel is the part that fails first on cheap surface cleaners. BE Pressure uses their heavy-duty swivel here, and it has a grease fitting so you can maintain it. Add grease once a week and this swivel will last for years. Skip the grease and you will be buying a replacement swivel in a few months.

ABS polymer dome. Lightweight and tough. It will not dent like aluminum and it will not crack like cheap plastic. The lightweight housing also means less fatigue during long jobs.

Nylon bristle skirt. Keeps the spray contained. Less splashback on walls, doors, cars, and you. Clients notice when you keep their property clean while you work.

3/8" quick connect inlet. Standard fitting that works with most professional pressure washer hoses. Snap it on, snap it off. No wrenches needed.

What You Can Clean With It

Pretty much any hard, flat surface. Here is what most contractors use it for:

• Concrete driveways and sidewalks
• Parking lots and parking garages
• Gas station pads and drive-throughs
• Pool decks and patios
• Warehouse and shop floors
• Loading docks and ramps
• Brick pavers and stamped concrete
• Restaurant patios and outdoor dining areas
• Dumpster pads

For best results, pre-treat heavy stains or grease spots with a degreaser before running the surface cleaner over the area. The surface cleaner removes surface dirt fast, but deep oil stains need chemical help first.

Sizing Guide: Is 20 Inches Right for You?

The general rule is 4 to 5 inches of cleaning path per 1 GPM of flow. So if your pressure washer puts out 4 GPM, a 16 to 20 inch cleaner is the right fit. If you are running 5.5 GPM or higher, you could step up to a 24-inch or 28-inch model for even faster coverage.

Running a surface cleaner that is too big for your machine is a common mistake. The arms will spin slowly, cleaning will be uneven, and you will leave streaks. Match the cleaner to your flow rate and you will get the best results.

Maintenance Tips

Surface cleaners are simple tools and they do not need a lot of upkeep. But a little maintenance goes a long way:

• Grease the swivel weekly. This is the most important thing you can do. A dry swivel wears out fast and a replacement is not cheap.
• Inspect the spray nozzles. Worn nozzles lose pressure and create uneven spray patterns. Replace them when cleaning performance drops off.
• Check the spray bar for damage. If the bar hits a curb or edge, it can bend. A bent bar causes vibration that will destroy the swivel bearings. Stop using it immediately if you feel vibration and inspect the bar.
• Rinse after every use. Run clean water through the unit for 30 seconds after each job to flush out sand and debris.
• Store it flat. Hanging a surface cleaner by the handle can put stress on the swivel connection over time.

Frequently Asked Questions

What PSI pressure washer do I need to run a surface cleaner?

You need a minimum of 2,500 to 3,000 PSI to spin the arms effectively. Below that, the arms may turn slowly or not at all, and cleaning results will be poor. This Whirl-A-Way is rated for up to 4,000 PSI and 8 GPM, so it handles anything from a solid residential machine up to a commercial rig without issues.

Does the pressure get cut in half because there are two nozzles?

No. Pressure stays the same throughout the system. It is your flow (GPM) that gets split between the two nozzles. So a 4 GPM machine will push 2 GPM through each nozzle at full system pressure. That is still plenty of cleaning power for concrete and most hard surfaces.

Will a surface cleaner remove oil stains from concrete?

A surface cleaner will remove surface dirt and grime quickly, but deep oil stains that have soaked into the concrete will leave a shadow behind. Pre-treat oil spots with a concrete degreaser and let it dwell for 10 to 15 minutes before running the surface cleaner over the area. You will get much better results that way.

Can I use this surface cleaner on wood decks?

You can, but be careful with pressure settings. Wood is softer than concrete and too much pressure will damage the grain. Use lower PSI settings (under 2,000 PSI) and keep the cleaner moving at all times. Never let it sit in one spot on wood or it will leave a mark.

How close does the surface cleaner get to walls and edges?

The circular dome design lets you get within about half an inch of a wall. The spray bar rotates right up to the inside edge of the dome, so you get very close coverage. For that last half inch along a wall or curb, a quick pass with your wand will finish the job.

How often should I replace the nozzles?

It depends on how much you use it and what you are cleaning. Most contractors running daily jobs replace nozzles every 3 to 6 months. You will notice cleaning performance dropping off before the nozzles completely fail. Keep a spare set on your truck so you are not caught short on a job.
