What about a 20 volt power washer?

Yes, power washers in general should be 230V and need a 16A fuse, or ideally 380V. I know. But the idea here is to wash the boats. We have several, one of which is used for net fishing so it’s constantly dirty. The other ones have bird poop and stuff on them constantly. A portable power washer (if you can call it that) that can draw water straight from the sea could potentially be a handy thing to have even if it’s feeble compared to a proper mains powered one.

I would be very interested in hearing your experience with such a thing, seems like you have the ideal use case. An 18/20V leafblower can be very powerful so I don't see why the power washer can't be good enough. Maybe only a short runtime though. There are Worx adapters for Makita batteries.

I always wanted a portable power washer when I went to off road sites, the only option then was a trailer with a petrol powered washer and water bowser, too much trouble really.

I would suggest to make sure that the model you get can push at least 500psi. I had Ryobi's first one. Which was 300 or 350, and I pretty much stopped using it, since it couldn't barely wash spider webs off of my home walls and fence. They came out with a new one a few months back that is 600, and it's noticeably better and IMO worth the additional cost. I've done zero comparison research with other company's models, though.

Some of these have a waterproof enclosure for the battery, so a battery with an adapter may not fit some of them.

The Worx claims to be 27 bar, so not quite 400psi. This appear to be the Ryobi one, it doesn't sell for much more in this country. I like the waterproof battery case they include.

Euro site has a 41bar model

Well, shit.

So, I had the older Ryobi 350psi unit. I only used it a few times, but took great care of it. I found a thrift shop 40 minutes away that had the new HP 600psi unit, open box. Used, but looked clean and was $75 ($119 new). They took mine in for $40 for trade, and I got them to add a $10 charger in as well, so I left with the 600PSI sprayer and a battery charger, $35 out-of-pocket.

2 months later I wanted to use it for the first time today. No water suction. Took quick-connect off, and the gasketed filter inside was fully clogged, with what looked like a blend of concrete and mouse fur.

So I went in with a fully-functional tool with a waranty and $35 in my pocket, and because I didn't test it, I now have a non-functional tool, no warranty, and $0.

Goddamnit.

The pump is working though, right? It sounds fixable. Looks like there are some cheap brass fitting adapters, would that get rid of the ruined part?

It runs, but there's no suction. I've pulled out the fitting and filter, and put my hand up to the inlet, and there's no pulling pressure on it at all.

I suppose I could try to take it apart and see if there's something obvious wrong, but I know nothing about pumps, etc, so it'd have to look visually wrong, like a disconnected line or wire, or something visibly broken.

I forgot all about this thread. I tried it over the weekend, and... it's better than a garden hose, barely. It did clean the porch but slowly and not for long before the battery died. The 2Ah battery I had with the demo was way too small and the slow charger was way too slow. You'd need to go for a pair of the biggest (8Ah) batteries in the Worx platform and the fast charger to have any chance of making any progress. And if you've got access to electricity, the same kind of money will buy you a really good household power washer, or even an entry level professional one.

Ah shit, I thought you were suggesting that the blocked filter was the cause but that it wasn't a replaceable filter.

I found an exploded diagram and parts list on the EU site, should be the same for the US model:

There is quite a lot going on, it's quite complicated but maybe less so if taken a bit at a time.

Ooh, good find. Thanks for that. It's the old version, but I can't imagine there's *too* much difference.

Yeah, the clogged filter was just an indication that there's a deeper problem, hidden by the clean-looking exterior. It must've been used with some nasty water, was run until it died, then they sold it to the thrift store. That's my guess, anyway.
