have you ever offered this as a service?

what model do you have and or which model would you reccomend??

almost all pressure washers come with multiple tip widths.
a model with 4000 psi is referring to the zero point tip pressure.
10 degree tip is way less pressure
25 degree is way less
40 degree is way less

the bigger thing to be concerned with it GPM flow of the pump. it doesn't really matter what pressure it is coming out at if there really isn't any water coming out.

example 2500 psi with 3 gpm or 2500 psi with 1 gpm.
you can see which one will get done faster and which one will retain much better pressure with a wider tip which will further enhance speed.

Box stores have crap machines. if you really want to do this you are probably looking at $1200-1800 to get a machine that will do work quickly enough for you to make any money. And that is without the heat part.

our machine is 3750. You can damage bricks and decks before you know it. It will blast right thru siding etc. The extra pressure does come in real handy if you need to degrease or clean something metal.

I use various tips as needed. I think we got a 6.75 hp on it. Does the job well just need to get a new hose for it now.

Do be carful tho you can easily give yourself or others water burns with it or damage things/strip paint. Know what your doing. This is NOT the silly electric ones that claim 3k psi@ 1 quart a min.

I've got one that looks like the one you're looking at Grass Disaster, but mine is about a year and a half old. I bought it just for my personal use, cleaning the concrete drive and cleaning my siding on the barn. I've even used it to clean my car and truck. (Used the 40 degree tip) It does a great job on anything I've used it on. Like Precision said, "the bigger thing to be concerned with is GPM flow of the pump. it doesn't really matter what pressure it is coming out at if there really isn't any water coming out." You don't want a high pressure little stream of water, but a blast of water at high pressure. Three or three and a half gallon of water a minute is pretty good for a machine this size.The machine you are looking at comes with different tips, just like what I've got. If you choose this model, be sure and practice at home or your shop. You'd hate to go to a job and blow the siding off your customers home!! Then if you have a good enough growth in your customer base to get a bigger washer, you can move up to a commercial model. Just my .02.

What do you guys use for water when pressure washing? Do ya'll use one of those water tanks, like a 300 gallon one?
Also, how much would ya'll charge for a typical driveway and how many can you do with a 300 gallon tank?

I had a contactor ask me if we offered pressure washing too. I checked my insurance it was like 1000 more per year to be insured. I would be careful it would appear you can mess up alot really quick if you don't know what you are doing.

go on line and do a search.
try hydrotek website, they have a lot of good info.

you want a triplex with all brass workings.
If you are gonna be serious about doing driveways you will want to be able to run one of the flat surface cleaners. they look like a vacuum cleaner (sort of) and have 2-6 heads and spin. All you do is run over the drive like as if you were mowing and they get all cleaned. No worrying about wand control, no fussing with tips. it is all figured in and away you go. But most need 5 gpm or more. 17" - 38" swath


without knowing anything else about them I would go with the 13hp.

If this is a lark or just testing the water, I think I might line up some work first and rent one.
