I'm looking for a good quality pressure washer for cleaning cars. It needs to be able to draw from a water tank without assistance, and it needs to be reliable. About $200 is my budget, but I'd like to keep it as cheap as possible while still keeping quality.
Answer
For $200 you are not going to get any kind of quality pressure washer.
You need a washer which operates at 1800 PSI or higher pressure output to perform effectively. They start at around $350 - $400 dollars. I do not know of any commercially available pressure washers which will draw from an unpressurized tank - they all are designed to operate from a pressurized hose delivering 3-5 GPM @ 20+ PSI.

I am looking for a pressure pump(washer) that generates 1500-5000 psi applying 12V DC battery. How many batteries required ?
Can I buy such pumps in the market ? please give more information on it.
Answer
My pressure washer has a 5 horsepower motor and creates about 200 psi. The short answer is that car starter motors create 5 to 10 hp for a short while but get hot fast. One battery will do the job for a very short while. The easier way is to use an electric washer, convert the 12 vdc to 120vAC with an inverter and wash away. The amount of batteries will depend on how long you want to operate at high pressure. The more the better. Can you buy such a pump, sure, convert a small home electric unit. Another good source for this stuff is West Marine, check their website and they have a great tech staff and no I don't work there.
