I bought a Karcher as well this year--they had them on special offer at Halfords but there might be some bargains at B&Q. Buy the most powerful you can afford.
Depends what you want from it. I bought a Champion from Focus for 30 quid and Its cleaned acres of patio and other things.
Truoble is that really decent ones like the boat yard uses are very pricey.. most pressure washers in domestic service die when they freeze in the garage over winter, and it won't matter if its a Karcher or a cheapy like mine.
I would recommend Karcher, too. They can take water from a tank as well as from a hose pipe, which is very useful when away from mains water. I dont think that all pressure washers can do that.
Mine had a minor problem last year, and I found the Karcher folks very helpful. A local dealer supplied me with the spare part, which was easy to fit.
Before you spend your money, ask them for the run rating, some of the cheaper ones are rated to run for only 20 continuos minutes and have a plastic pump.
Take care...

79 quid out of B&Q ..... does a good job and is small enough to tuck away in the corner of the garage. Small Karcher .... when IO checked the spec. - it had the same pressure as the one twice the price and also able to fit onto a small trolley specially designed for the job ... never needed it though as its easy to carry.

Bilge Keelers get up further ! I only came - cos they said there was FREE Guinness !
has been run continuous for entire bottom clean of my boat without problems and I've had it for 5 years now .... still works a treat. In fact I only get it out once in a very rare moment in summer etc. So it sists for months - then gets called on to start and clean off the boat - sits again till next winter !!

Before the Karcher I had a 99 quid Italian job ... can't remember the name, but it was really good - but after two winters the pump siezed due to lack of use .... was told by service it was uneconomic to repair .... B&Q shortly after stopped selling them !!

Whatever you buy, keep it well away from the windows and anywhere else that Silicone sealant is used (eg around cleats and stanchions etc etc.)
Otherwise..... there wont be silicone sealant there for much longer if you get my drift!
I now keep my washer at home for use on the car only!
I bought a small green one from Homebase for £46 last year and it works well. I needed to have one to clean my pontoon, so I bought the cheapest I could find because it was going to run on seawater - no power or water on the pontoon (I used a portable generator for power). It's still going. It's light enough to carry easily and can even be used up a ladder (tied on of course!). When it stops I'll throw it away and buy another.
On small Chemical ships when we used them - we often used sea water in a header tank ---- it is slightly abrasive due to the salt in it and it cleans better than fresh. BUT its bloody corrosive to the pump seals and also leaves mineral deposits evrywhere in the pumps etc. So the answer is to give it a really good blow out with fresh water after ..... the ones on ship lasted years as long as we remembered that. Another little known fact ..... TEEPOL was Shell product via a second company. Designed originally for Sea water mixing !! Not a lot a people know that !!!! But we in Shell used to have discount on the stuff !!!!

I understand that those with induction motors are far more robust.
I would go with the cheapest Karcher which has the induction motor, should be about £80/£90
I brought one paid over £200 for a kew pro thing and the posh brush plus washer bottle
absolute crap and it broke and the dip head manager at the home base place got right stroppy !!! but I did get my money back . Ha and had words with head office so big nose had a black mark ( well better than a black eye :-}
This discussion might be relevant to a big d.i.y. task I face.
Re. osmosis treatment, my survey report advises me to pressure clean after the peel and grit blast, then 7 days later steam clean, then extended drying, then another steam clean prior to recoating.
I need a general-purpose pressure cleaner, but for a few more £'s could I buy a steam cleaning facility?
Dont buy a steam pressure washer. HIRE ONE. They are very unreliable and do not have a long life, even expensive profesional ones.
Buy a reasonable normal pressure washer (mine cost under £50 from B&Q) It will last if not kept outside in the winter.
A steam pressure washer is too big to keep indoors in the winter.
I would suggest that a good Osmosis Centre would put paid to the treatment required.
As a surveyor - I would never stipulate exact treatment as the Osmosis Treatment guys are the experts in actually doing the job - not the Jack of all Trades Surveyor.
Hopefully the Insurance Co. etc. will allow you leeway to consult actual Treatment specialists and NOT insist on the Surveyors version of cure !!
Very interesting post that ..... got me really thinking !!!!
Sorry but I think the Surveyor really stepped out of his arena !! As an Owner of a Professional Commercial Survey Co. and Labs etc. - I would hang - draw and 1/4 any surveyor of mine who was so specific and could possibly cause grief for the client !!!!!

Well the surveyor knew I was thinking about treating the osmosis myself so his action plan attached as an addendum to the survey, was welcome.
To be honest when I phoned around osmosis treatment specialists in the UK they rattled off a procedure that was almost identical to the surveyor's advice. However one yard claimed they could use hotvac to accelerate the whole process down to a 5 week liftout-to-relaunch schedule. The same yard also said re laminating was an optional "delux" extra.
My surveyor snorted indignation at the notion of re lamination being an optional extra, if a hull looses mass during peeling and grid blasting it should be replaced as a routine matter. He also thought a 5 week hotvac based turn around was an abuse of new technology and felt that hotvac should be used to complete the drying process after a period of air drying.
Do you not consider a post-peel steam clean an essential step in an osmosis repair job?
Our boat was professionaly treated for osmosis recently. After peeling and grit blasting, they steam cleaned every few days for some weeks. Our drying out took in the region of 8 months
The manager of the centre preferred the leaving outside till the readings came down method then finishing with IR lamps inside.
Problem is we missed a whole season - hopefully the price for a good treatment?
