Portable/Cordless pressure washers

Post by Honkytonk » Sat Jul 13, 2019 11:09 pm

Evening all,

In my ongoing strive to look after the car(s) properly without having a driveway of my own on which to happily do work or clean them, I've been looking into the best way to provide some kind of portable fix for washing the cars.

Long and short of it is I park my cars in what is essentially a public car park about 50m round the corner from my house. No hose, electrical socket, or kettle to be found, which makes life just that little bit more difficult when you're doing something! I want something that I can snowfoam my car with and then rinse it off without buying 60m of hose and electrical extensions and trailing them down the high street in front of two pubs and a bookies...

I've been eyeing up the Worx Hydroshot as it seems to be almost precisely what I need - if you buy an adapter you can even attach plastic drinks bottles to it so you literally have an all in one washer with no cords whatsoever. I'd probably more likely run it with a float in a jerry can of water or similar, depending on how much it gets through while washing. They're not the most powerful in the world but I don't want to strip paint with the thing...

Anyone have any experience with one, or have something else they've used that they would recommend for such a task? Not really overly enamoured with petrol pressure washers, they're too bleeding noisy!

Sorry to say a bucket of water is all I can recommend - however it does work and is a classic....

This guy is very critical and he's given it a thumbs up. Bit of a tear down

Cheers chaps. The full kit dropped to £90 on Amazon yesterday briefly but I missed it...

Just one bucket 350matt?! Not two?! ;)

Hi

My wife got me one for my birthday.

The battery will do 2 cars. Obviously you still need water so you will be going back and forth for that. It has an attachment so you can use snowfoam. It’s not the most powerful spray of all time but I like using it. I think there is a 40v version. The first thing to do after using it is to put the battery back on charge.

Cheers Dove! Do you know how much water it gets through? I've got a couple of 40l water porters so bringing one of those with me is probably how I'd be managing the water side of things.

That’s quite tricky to answer exactly as I’m sure everyone washes their cars differently.

Normally I’m washing 2 cars at the same time but getting to water isn’t a problem. I normally do the wheels first on their own and then snow foam the cars. This then needs to be rinsed and then the cars are shampooed, rinsed again and then dried. I use a small bucket for the wheels and 2 Dodo Juice buckets for the rinsing and 2 buckets for shampooing (one shampoo on and one to rinse the mitt). I think the big buckets are 20l each so I would say what you have is fine.

My general experience with pressure washers is that they use a lot less water than just a hose, even one with a jet nozzle.
When I pressure wash our car(s) I'm always surprised how little water is left on the ground.
That said, no amount of pressure washing, even with a snowfoam, will remove the thin film of surface grime, that has to be shifted with a cloth/sponge/brush.

Cheers, that's helpful! Quite agree everyone has a different method. I'll rinse the car, lightly shampoo it by hand as I have no lance, let it soak, rinse off, go at the wheels, rinse again, shampoo top down on any problem areas, rinse a final time, and then dry.

Polish and wax follows if it requires it.

I'm not planning to use it to 'clean' the car with solely, just to provide a snow foam to soak the dirt with, and the ability to rinse effectively with no tap or electrical connection! All those rinse/shampoo phases above are going to be helped a LOT...

What with the black finish, I want to be touching the car as little as possible - big white scratches being particularly visible if I happen to grind some dirt into it with my inexperienced cleaning actions. Also it soaks in the heat so I can't leave anything for too long if there's even a modicum of sun about!

Me mind's made up, I'll be getting one next time it drops to the sub-100 mark (alas, £90 package on Prime day is now £150...), and I'll crack it out on the Vectra and the RX8 (silver car and a black car, nightmare...) and put down my observations in case anyone else is thinking about one.

One other option and I know some people have some mixed feelings on this, is a waterless wash. I have similar issues with lack of water to my car so I use Supagard Aqua Free, with plenty of microfibres and I think it comes out quite well. You can do the alloys with it as well. I've used it on my RX8 (also a black PZ, see the photos section for some recent pics after a clean) and Soul red CX5, and I think it leaves a pretty good finish as you don't get any watermarks, and you get some wax on it so water beads off nicely after.

The scratch thing always seems like a worry, and I was always unsure but reading about it on many detailing websites and trying it, I think it seems to be ok. You need to let the spray dwell a bit, and use plenty of good thick microfibres, but so far I haven't seen any scratching after using it. Time will tell as with all cleaning methods it could be inflicting micro scratches, so I'll keep observing.

Of course during winter, when you need to get underneath and under arches you do need water but I think this method is ok for 9 months of the year.

For snow foam I use a Mesto Foamer. Will need to pump it a lot to get the car covered but it lays down phenomenal foam

Thanks chaps, useful info. I've used a hand powered pressure sprayer before for foaming and they work a treat if you get your nozzle setting right!

That poketpower looks ridiculously tiny! Is it battery powered?!

I still haven't got around to purchasing one (more important things to spend money on unfortunately) but having done a lot of reading since I initially posted, there are now two versions available: W629 with a brushed motor and less power (which apparently is a pig to charge the 2ah batteries), and W630e with a brushless motor and better flow rate (and a 4ah battery which has fast charge). The first can be had for under £100 now, but typically I want the shiny new one now, which is ~£200 for the full kit.

It’s about 10” long 5.5” high and 4” wide.
Internal battery that can be charged by Wall Charger Cig lighter ETC.
But can not charge and wash at the same time.

Couldn’t really justify the cost of the Worz one at the time.
It does want I want it to do.
And sits in the the Mequires Bucket ready for use.

Is it better or worse than the Worz I’ve no idea.

Welp it's payday and I had loads of overtime burning a hole in my pocket so as this is currently £169 on ebay I finally bought me one.

Just in case anyone else is interested, there's a new one out in the US (WG644) that's 40V/450psi (takes 2x 20v batteries) but I am done with waiting so went for the WG630 instead.

Just a headsup that the Worx powershot full kit is currently £109 on Amazon

I've had one for a couple of years, bought the bare bones unit (which comes with the assessories bar bucket plus no battery) and then took a gamble on a 3.0ah and 5.0ah JCB battery from B&Q which were on sale for £20 and £30 respectively which is less than half the price of the Worx ones and they are fully compatible.
https://www.diy.com/departments/jcb-20v ... 263_BQ.prd


One thing to keep in mind is that you only get the full pressure when the full lance is attached, if you use it with just the small attachment the output isn't very good, the 3.0AH battery is enough to do two cars.
