Power Washer

Baldytyke88

Just looking at a Ryobi cordless power washer. The stated pressure is 22 bar, a quick Google says power washers are 110-180 bar.

So is 22 useful, I like the idea of being able to power wash my VW Crafter.

The average power washer has a pressure of 110–180 bars, but the pressure needed depends on the task you're doing: 

• Light duty: 1,000–1,500 PSI, good for cleaning gutters, windows, and soffits
• Medium duty: 1,500–2,000 PSI, suitable for cleaning wood, brick, and concrete
• Heavy duty: 2,000–3,000 PSI, ideal for cleaning driveways, sidewalks, pathways, boats, and yachts
• Extra heavy duty: Over 3,000 PSI, good for heavily stained driveways and caked-on dirt

Another straight from AI answer above. I literally got the same answer when Googling “average power washer pressure”.

It might be enough pressure for cleaning a vehicle, I wouldn't expect it clean a yard though. There are more powerful cordless ones that cost less

More power, but more expensive @£200

"WORX Nitro HydroShot WG633E 20V High-Flow Cordless Portable Pressure Cleaner Power Washer with Brushless Motor Up to 56 Bar Pressure"

But it does not list the PSI

Just convert the BAR rating.

You need your 14.5 times table!

A hosepipe with a decent adapter on the end would probably give you enough to rinse over your car than buying a fancy cordless pressure washer. I wouldn't use one. I have a proper mains fed pressure washer that does all I need it to do and wash the car. I'd either buy a proper mains washer or not bother at all.

Imo, a pressure washer is good for shifting the main layer of dirt from paintwork only, prior to the use of a mop or sponge to actually clean the vehicle. This requires some care, with the pressure turned down, or the lance not held too close to the surface.
To expect a PW to actually clean your car would require you to blast it too strongly, and that would almost certainly remove the bulk of any wax or coating you've been giving it too.
So, assuming you aren't intending to blast your lovely VW clean, I'd have thought that the cordless washers would be fine - ideal, in fact - for this initial crud-shifting.
(Horrible flashback to me giving mil's wee Twingo a quick wash whilst I was doing my own car. Karcher for initial dirt removal, and... what's this stuff? Oh, just the side decals...)
I use a thick mop on an adjustable pole these days, and it's an absolute doddle. And after rinsing off, I use a trigger-spray of supposed 'graphene/ceramic/whatever' to apply a little, and then wipe over with the same mop. Not exactly the proper process, but takes seconds, and rain beads beautifully afterwards.

Cordless or not, do not leave them in the shed over Winter.
If you get a hard frost it can damage it/stop it working, and this damage is not covered in the guarantee.
I know from experience........

Slightly better than a garden hose, but not really up to much and would certainly be of no use if you plan to use a snow foam gun. Even the mains powered ones at the lower pressure end struggle there.
