Recommended pressure washer?

After recent attempts at cleaning my bike in the shower and the ensuing anger from my GF (I know, I can't understand it either?!) I am in need of a portable pressure washer for when I get home, so I can clean the bike in the alleyway. Has anyone used one of these

Streetwise Portable Power Washer (1056) Uses limited water. Caravan, Car, Motorhome Cleaner!: Amazon.co.uk: Car & Motorbike

or can recommend another, for preferably under £50, that has a water tank (I don't have access to a garden hose).

I've been tempted by those but space is short in the flat and I don't like cleaning bikes anyway. You can get those weeding ones for cheaps and they're low pressure so won't blast off heavy stuff but also won't do bad things like blasting through bearing seals.

I have in the past biked along to my local petrol station and used the one they have. They aren't the ones you drive a car into and out the other side but more a little booth, whatever the minimum charge is should do most bikes and you won't have to faf about pumping it for weeks to get pressure like the one in your pic. If you went every week and it cost you £1 you might get the cost of a pump in a year but really you are looking at a couple of years(longer than the cheap pump lasts you?)

If you do try to buy one then try and test it before, often the portable ones are used for spraying plants, cleaning carpets and other things that just need a light spraying of something that dilutes in water, for a bike you really just want something to pump lots of water and displace the dirt.

The Mobi ones are supposed to be alright.

You can use the ones at garages - but they will do bad things to your bearings if you point them in the wrong place.

i always pressure wash my bike especially in the seat tube :)

I used the jet wash at the garage. usually costs a couple quid all-in

gets it super clean though

I use one of these,

invaluable for getting all the crud out from behind the cranks, and under the top of the forks. Also gets the hubs shiny, inside and out. A grimy mech sparkles after a few minutes of sustained blasting.

Also as valuable as my bike , if only

If you do this make sure you then go home and replace all the grease in all the things.

Think it needs removal as the 14.5mp motor would imperil poorly wired external electrical sockets. The UK tends to run at 13A.
