I purchased a Dewalt 4400 Psi 4gpm Machine to atleast start my pressure washing business for this summer, problem is i cant choose which surface cleaner to purchase any advice? General tips for a new Pressure washer would also be greatly welcomed!
You have several to choose from, but 19” is going to be your max size with a 4gpm. I started with a 16” Whisper Wash Ultra Clean, it worked decently enough until I could get a better machine.
I like the Ultra vs the Classic as I can stand in between the bars when walking. Some cleaners also prefer castors (wheels).
Whatever you do get be sure you can change out the tips to dial down the pressure to about 2500psi max.
I went with the GP Hammerhead 18" to go with my 4gpm. I added the wheel kit to it too. I went with it because it was about in the middle for price. It’s been 5 years now and it’s still working great. General rule is 4" per gpm, but i went 18" incase I ever upgraded. It cleans great, I’ve been happy with it
I can learn how to change out the tip but which tip would i need to get, is it like a nozzle with a certain degree or a specialized tip to actually lower the PSI leaving the machine?
