What is the minimum amount of HP and PSI I should look for in a new power washer? I am a painting contractor so it would be mainly used for cleaning off old paint from the exteriors of houses (brick, cedar, etc.) and decks and so on.

While I am by far a expert on pressure washing. i do have a neighbor that has been in the feild for years. He has always told me that a hight PSI is good but the higher the GPM is the better it cleans.

He only does it part time now for 1 painter (he has a cushy big money job now lol).

I think 6 GPM plus is where you want to be to work more effeciently(spelling?). I know alot of wahsers at lowes and the "depot" are around 4 gpm. They will work they will just take you a little bit longer to get it done...

Like I said I am no expert in this area.. just passing along what I have been told.

The highest that HD carries is 3700 PSI, 13 HP and pushes 4 GPM. They want $1000 for it...

This thread pressure washing thread has some really good information about machines and techniques.

I have one of these. The only downside is that I can't lift it into my truck alone.

I use a 6.5 gallon per minute gas Hydro-tech with a diesel burner. I wish I would have bought an 8 or 10 gpm diesel engine and burner due to the much faster results and reliability.

Stay away from Hydro-tech brand power washers…there are to many bells and whistles that will break down and are “dealer only items” My dealer charges $70 per hour and pretty much has to disassemble the whole unit to get to anything.

I will also stay away from CAT pumps. Years ago I let the first one freeze thinking winter was over, that was a $1,500 mistake!

The second time that I had my head up my ass was when I sat down the gun with the machine running to speak with a customer and the second pump overheated and busted in about 8 minutes. I rebuilt that one but it was still over $450 for parts.

Most of the guys I know have switched to General pumps and always with belt driven units.

Best of luck

Pipe,
That thread is awesome... I probably should have just done a search before posting... Thanks!


Thanks also for the advice and warning Jesse. I'll stay away from Hydro-Tech.

Would it be improper if I asked what you guys paid for your washers? Anytime I mention picking up a peice of equiptment for the business to my partner and it costs over $1000 he nearly has a heart attack. I then have to put on my salesmen hat (the one I use with customers) to try to convince him why it will benifit us in the long run.

The unit was around $8,000 but I have another $4,000 wraped up in hoses, reels,accessories, extra parts ect... (this thing payed for itself in the first year)
