The problem

Everything you've already tried, and why it let you down

Your car isn't dirty because you don't care. It's dirty because every way of cleaning it is a project.

The lot with no tap
The lot with no tap
“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.

The $20 car wash
The $20 car wash
“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.

The mud that sets

“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.

The lost Saturday

“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.

Inside the WashPro

Built to wash without a tap

Everything you need fits in one case. Here's what each part does.

Built to wash without a tap
  1. 1
    6-in-1 nozzle wand

    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.

  2. 2
    Self-priming pump, up to 900 PSI

    Pulls water straight out of a bucket, with no tap or mains pressure. Three settings: 400, 650 and 900 PSI.

  3. 3
    5 m suction hose and filter

    Clicks onto the quick-connect inlet. The mesh filter sits in the bucket and keeps grit out of the pump.

  4. 4
    21V 4.0Ah battery

    Slides into the handle. About 30 minutes of spray per charge, enough for a full car, foam and rinse.

Use it everywhere

One washer. Everything you own.

From the driveway to the trailhead. If it gets dirty, WashPro reaches it.

Our story

We tested eleven cordless washers. Only one made the cut.

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.

No tap, no outlet

No tap, no outlet

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.

Eleven boxes on the bench

Eleven boxes on the bench

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.

A long winter of no

A long winter of no

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.

The keeper

The keeper

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.

FAQ

Your questions, answered

Everything people ask before buying, sorted by topic. Still wondering about something? Email service@techcarauto.com and a real person will reply.

Do I need a tap or a power outlet?

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.

Can I use the foam cannon with bucket water?

Yes. Fill the foam bottle with car shampoo, draw water from the bucket, and it foams the same way it would on a tap.

How much water does one wash use?

Around 4–5 gallons — roughly one bucket. A touchless car wash uses 30–40.

What else can I wash with it?

Anything you’d rinse with a garden hose: wheels and tires, bikes, patio furniture, grills, kayaks, trash bins and muddy garden tools.

Can I use a bottle instead of a bucket?

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.

How long does it take to set up?

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.

Is it as strong as a corded pressure washer?

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.

How long does the battery last?

About 30 minutes of spraying on one charge, enough for one full car including a foam pre-wash and rinse.

How many batteries come in the box?

One 21V 4.0Ah battery comes with every kit.

Which pressure setting should I use?

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.

How do I charge the battery?

Use the charger in the box. Take the battery out of the handle and click it onto the charger.

Will it scratch my paint?

No. Use the Soft or Standard setting with the fan nozzle for panels. Keep the jet nozzle for wheels and wheel wells.

Which soap can I use in the foam cannon?

Any pH-neutral car shampoo. Avoid dish soap, which can strip wax and dry out trim.

Is it safe for wheels and tires?

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.

How do I store it in winter?

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.

How long does shipping take?

Free shipping on every order. Processed within 1–2 business days, delivered in 5–7 business days with tracking.

What if it isn't right for me?

Email service@techcarauto.com within 30 days of delivery for a full refund. Damaged or faulty units are replaced first, questions second. We answer within 24 hours.

How do I start a return?

Email service@techcarauto.com within 30 days of delivery with your order number, and we’ll send you the return instructions.

What does the warranty cover?

Defects in materials and workmanship under normal use. One year comes standard on every kit, two years with the Pro Kit or the Inside & Out Bundle.

Can I track my order?

Yes. Every order ships with tracking, and you’ll get the tracking link by email as soon as it leaves our warehouse.

For someone thinking about cleaning after a road trip, It is the sort of task people face when bugs and dust gather on the front end. That kind of flexibility could save a lot of hassle.

Rose Garza

Consider cleaning plastic bins. This comes up when outdoor containers get dusty. The main attraction would be cleaning without dragging out extra gear. The result would depend on the surface, dirt, and water source.

Allison Griffin

In a scenario involving foam prewash, This comes up when a foamy first pass is part of the routine. Having the accessories together could make setup less of a chore.

C
Cole Adams

In a scenario involving small SUV washes, It is especially relevant when there is not much room to store equipment. Being able to pack everything away neatly would be a nice bonus.

One practical situation is morning vehicle prep. That matters because time is limited. A compact kit sounds easier to reach for than bulky equipment.

Zachary Perry

For someone thinking about occasional outdoor jobs, The reason is simple: there is no need for a large machine. For everyday messes, convenience matters more than a complicated setup. That is why realistic expectations and clear instructions matter.

Morgan Hamilton

A common use case is spray nozzle changes. This comes up when different surfaces need different spray patterns. It seems well suited to light, regular upkeep rather than major jobs. The sensible approach is to test how the spray behaves before moving to a large area.

Excellent product, works well under good pressure for a household product - the hose comes folded and that's why at first it doesn't dispense water properly.
