Know all too well about restrictions and no water to wash a car and I will NEVER live in a BS place like that again run by a bunch of anal retentive ****s. WOW I hate these people. So I looked at the Bosch Pressure washer above. Ehh only 15bar's is just a hair over 200PSI is not really a "pressure washer" as it has no power. I don't recommend anything over 1500PSI for auto use. Do recommend a cheap 1100-1200psi AC electric pressure washers for cars because they are around $100 or less on sale. Be aware you cannot use bleach in the reservoir or run through any cheap machine. It will eat all aluminum in it's path ruining the unit in short order. For use with chlorine must use a commercial washer with ceramic pistons, where the pressure block is typically >$400 alone. My buddy is a painter, used cheap 2500 PSI gasoline powered PW's (engine is a must 4 what he does) for many years. Kept telling him to get something a bit more powerful like a 4000PSI that'll move at least 3 gallons per minute. Always used the excuse that these 2500's were CHEAP, buying them up used for $100, fix, fix, fix and run til engine dies, get another. He finally listened and bought a Mi-T-M 4000psi PW. It was stolen from a job and the boss man then took his good old sweet time to replace (months), so he went out and bought another, better, Aluminum frame lite weight full kit with a 6.5HP 389cc Honda engine, additional extension wands, hoses, path clearer (big one)... has enough power that they almost glued a brick to the top so it wouldn't fly off the ground. Can do all the second and third story's of a building standing on the ground. https://www.amazon.com/Mi-T-M-CA-400.../dp/B00J9HAVN6 only he purchased for $1600 with all accessories from Sherwin Williams with his discount. Machine is 125lbs so it's actually lite enough to load and unload by yourself (if you have to, still awkward) vs must have a second person to man handle the heavier steel framed units that are 175lbs and up. I just wish my Infiniti Q50 had a bigger trunk, can't even get something that big home. lol
