Gas or electric ? Minimum GPM and PSI recommended ?

I can't say.

What are you planning on washing?

I bought one a couple of weeks ago. Gas and 2,350 psi. Only $279 from Home Depot. It's not the biggest beast in the world, but our deck has cleaned up beautifully.

Electric = convenient, cheap, low power.

Gas = more maintenance, more powerful, more expensive.

What are you planning on powerwashing? And how often? Small jobs once or twice a year? Rent one when necessary instead.

Mine's rubbish, does nothing except swirl dirt around. Kärcher, 1750 psi, electric, can't remember the price but it wasn't much.

I purchased a gas 3500psi Karcher a couple of years ago, and it's been great. Copes with a muddy tractor, ATV, our truck etc etc perfectly well.

QED

Absolutely, let that be a warning to you, BE members!

And don't think buying the "stop jet swirling around" brush attachment will make it any better, because it won't

I rented a gas one from the Home Depot to do the deck "be careful" they said "it'll dig holes". It hardly made a dent.

My weedy one did gore the drywall in the garage, and take some paint off the door but I can do that with a fingernail so it's not much of an achievement.

Car and deck mainly

KÄRCHER, 1600PSI cost me $89 from Walmart. Works great for the car and outside jobs, driveway, deck etc.

Thanks mate.

Hiya Bink who is that lovely little girl you are sitting with?

Ended up getting Kärcher 2000 PSi 2GPM gas one from WalMart $195.
Will have to wait to try it out so I don't create an ice rink on the drive.
