The problem

The Hose Doesn't Reach. The Grime Does.

No outdoor tap, a socket on the wrong wall, a plug-in washer that takes longer to set up than the job. So the patio stays green.

Will it clean mine?

Yes, easily

Yes. Foam it with the bottle, then rinse on a wide fan or shower setting. Keep the pinpoint jet off paint.

AI SUMMARY from the reviews

Reviewers say it cleans the car, patio and bins from a single bucket with no tap or cable, and that the foam bottle and hard case feel like extras. Many recommend the Weekend Kit for the second battery. One reviewer notes that deep stains on an old deck still need a bigger machine.

  • No tap needed
  • Light in the hand
  • Foam is fun
  • Get the spare battery
  • Not for deck stripping

  1. Megan R.Verified buyer10-19-26

    No outdoor tap, no problem

    We rent a townhouse with zero outside taps. I fill the bucket at the kitchen sink, carry it out, and the car is done before my coffee goes cold. I did not think a bucket could do this.

  2. Dan K.Verified buyer10-18-26

    The patio went from green to grey

    Three summers of algae on the slabs. One afternoon, a narrow fan and two buckets, and my wife asked if we had new paving.

  3. Priya S.Verified buyer10-17-26

    Light enough to actually use

    My plug-in washer lived in the shed because setting it up took longer than the job. This one comes out for ten-minute jobs: the bike, the bins, the front step.

  4. Tom H.Verified buyer10-15-26

    Strong, but get the second battery

    Did half the car and the garden gate before I swapped batteries. Glad I took the Weekend Kit. It is not a gas washer, but it never pretends to be.

  5. Lena M.Verified buyer10-14-26

    The foam bottle is the fun part

    Clip it on, the car turns into a snowdrift, rinse it off. My kids now fight over who gets to hold it.

Questions

Before You Fill the Bucket.

Do I really not need an outdoor tap?

Right. The inlet hose drinks from any container of water: a bucket, rain barrel or water butt. Fill a bucket at the kitchen sink and carry it out. If you do have a garden hose, you can use that too.

How long does the battery last?

Run time depends on the nozzle setting and how long you hold the trigger. For bigger jobs, the Weekend Kit adds a second battery so you can swap and keep going while the first one charges.

Is it safe on car paint?

Yes, on the right setting. Use the foam bottle, then rinse with a wide fan or the shower setting from a little distance. Save the pinpoint jet and narrow fan for wheels, tyres and stone.

Is it as strong as a gas pressure washer?

No, and it does not try to be. UNTAP is a cordless, grab-and-go cleaner for cars, patios, bikes, bins and windows. For stripping a whole deck or an oil-stained driveway, rent a big machine.

What comes in the box?

The washer, extension wand, 6-in-1 nozzle, 48V battery and charger, 5 m inlet hose with strainer, foam bottle and hard case. The Weekend Kit adds a spare battery and a fold-flat 20L bucket. Every order includes the free cloth set.

How long until it arrives?

Orders ship within 2 days and usually arrive 7 to 10 days after you order. You get a tracking link by email as soon as it ships.

What if it's not right for me?

You have a 30-day money-back guarantee. If UNTAP isn't right for you, email us within 30 days of delivery with your order number and we'll refund you in full to your original payment method, including discounted kits. Keep the free cloth set.

Is there a warranty?

Yes. The washer, batteries and charger have a 1-year warranty against defects in materials and workmanship. Email us your order number and a short video and we'll repair or replace it.

30-day money-back guarantee
