Pressure washer lifespan

What would folks say is the expected lifespan of a pressure washer?

The powerspeed nozzle on my Nilfisk is knackered, and it would appear that a replacement is going to set me back around £35 plus carriage, and currently there is no date available as to when it might arrive (the nearest I have gotten to that answer was that I would get an email by 7th May telling me when it would come!) - indeed, many places show the nozzle as no longer being available, which is suggesting that the ones that are available are pattern parts, which in turn would account for them not looking the same as the current one.

I am also looking at the cost which is about a third of the price of a whole new machine with the various nozzles (or about 20% of the cost of a 'good' one) and considering that this machine is in fact around ten years old, and I am starting to wonder if I am at that point where I have to cut my losses and go for a new one. It seems really daft to have to do so for the sake of a busted nozzle, but then again is it wise to spend a chunk of money on a small part of an old machine that could die next week?

 

Thanks all - I am now leaning toward a new one as I washed the car with mine today (I have a snow foam lance head for it which is simply amazing) and when I was putting it away I noticed that the pressure hose had a kink in it which suggests that it is failing internally (the rest of it is hard and would not bend to a kink) - so that would be a new hose and a new nozzle for a machine that has to be 8 years old if it is a day.

I would have another Nilfisk though, as it has been superb and has had a lot of use to be fair to it; I bought it originally having had three Karcher's fail in fairly quick succession (don't think I had more than two years out of any of them), so the Nilfisk is a vast improvement. I had a brief look at Kranzle earlier @Liz the pot - they look the dogs dangly bits, but they also have a price tag to match!

The fly in the ointment here is going to be my shredder woes which I will be posting separately about......

 

Good news! I found a place selling a replacement nozzle and hose for a smidge over £30 delivered. An equivalent would be around £200 or so, so I think £30 is worth a punt even if I only get another year or two out of it.
