“There's no tap in our lot. I've paid for car washes for three years.”
With WashPro: Fill a bucket in the kitchen, carry it down and wash right where the car is parked.

“Twenty dollars every two weeks, and it still misses the wheel wells.”
With WashPro: No more per-wash fees, and the jet nozzle reaches the wheel wells a car wash misses.

“After a trail run, the mud bakes into the wheel wells before I can get home to a hose.”
With WashPro: Rinse at the trailhead from a water jug or a bucket, before the mud sets.

“By the time the hose and the extension cord are out, half my Saturday is gone.”
With WashPro: Battery in, hose in the bucket, trigger. Under a minute of setup.
Everything you need fits in one case. Here's what each part does.

Six spray patterns on one wand. Twist the tip for a tight jet on wheels and mud, or a wide fan for paint and glass.
Pulls water straight out of a bucket, with no tap or mains pressure. Three settings: 400, 650 and 900 PSI.
Clicks onto the quick-connect inlet. The mesh filter sits in the bucket and keeps grit out of the pump.
Slides into the handle. About 30 minutes of spray per charge, enough for a full car, foam and rinse.
From the driveway to the trailhead. If it gets dirty, WashPro reaches it.

Road film, pollen and bird mess off in one pass, right where it's parked.

The jet setting gets brake dust out of the spokes and the wheel wells.

Rinse the trail mud off at the trailhead, before it dries on the frame.

Furniture, grills and pavers, without dragging a hose across the yard.

Rinse salt and sand off at the ramp, straight from a bucket.

Hose out trash bins and muddy tools anywhere in the yard.
One bucket from the kitchen tap. The battery clicks in.
Foam cannon on. Grit lifts before you touch the paint.
Standard setting, roof first, down to the sills.
Max setting into the spokes and wheel arches.
Towel off. Case back in the trunk.
How it stacks up against the two ways most people wash their car today.
WashPro
Car wash
Corded washer
Car wash prices vary by location and package.
We wanted one thing: a clean car without a tap, a cord or a trip to the car wash. Nothing we tried did it well, so we went looking.

It started with a dirty car and nowhere to wash it. No tap in the parking lot, no outlet on the street, and the nearest car wash a drive away.

So we ordered every cordless washer we could find, eleven in all. Most just sprayed a weak mist. Two died on their first charge. One leaked before it was even out of its case.

All winter we ran the same simple test: take a wheel caked in brake dust and clean it using only water from a bucket. One by one, they failed. Only one got the wheel clean.

That one became the WashPro. We added a foam cannon, the 5 m hose and a hard carry case, and then we put our name on it.

No. The WashPro runs on its 21V 4.0Ah battery and pulls water through the 5 m hose from any bucket or tank. No tap or outlet needed.
Yes. Fill the foam bottle with car shampoo, draw water from the bucket, and it foams the same way it would on a tap.
Around 4–5 gallons — roughly one bucket. A touchless car wash uses 30–40.
Anything you’d rinse with a garden hose: wheels and tires, bikes, patio furniture, grills, kayaks, trash bins and muddy garden tools.
Yes. The box includes a soda-bottle adapter, so you can screw a standard soda bottle onto the hose for a quick rinse when you don’t have a bucket handy.
Under a minute. Click in a battery, drop the filter end of the hose into your bucket, twist the nozzle to the spray you want and pull the trigger.
It’s built for a different job. Up to 900 PSI is more than enough for paint, wheels, mud, pollen, bikes and patio furniture, and gentle enough for clear coat. The difference is where it works: a corded washer needs a tap and an outlet, the WashPro only needs a bucket. Driveway, parking lot, campsite or trailhead, you can wash wherever the car is.
About 30 minutes of spraying on one charge, enough for one full car including a foam pre-wash and rinse.
One 21V 4.0Ah battery comes with every kit.
Soft (400 PSI) for paint and glass, Standard (650 PSI) for everyday dirt and road film, and Max (900 PSI) for wheels, wheel wells and caked-on mud.
Use the charger in the box. Take the battery out of the handle and click it onto the charger.
No. Use the Soft or Standard setting with the fan nozzle for panels. Keep the jet nozzle for wheels and wheel wells.
Any pH-neutral car shampoo. Avoid dish soap, which can strip wax and dry out trim.
Yes. Use the jet pattern on Max for brake dust and wheel wells, and keep the nozzle a hand’s width from the tire sidewall.
Run the pump for a few seconds with the hose out of the water to empty it, then keep everything in the hard case indoors. Don’t leave water in the pump in freezing weather.
