Commercial flatwork/Apartment cleaning build

Hi everyone,

Planning my rig out so I can clean large commercial properties like shopping center sidewalks, buildings, dumpster pads and apartment building breezeways.

Looking at a 5.5gpm/4000psi pressure pro hot water unit with a honda gx660 engine. 300 gallon tank, 14’ utility trailer, rear mounted 200foot pressure hose and garden hose reels.

Is 5.5gpm a big enough leap to allow normal walking speed with a 24" surface cleaner? I think 14’x6’ should be enough to have the unit, water tank, hose reels and leave enough room to add a 4500 watt generator and 30 gallon mix tank.

You can’t push more than a 16 inch surface cleaner comfortable with 5.5gpm. 19inch would be a stretch. You don’t need more than a 65 gallon buffer tank so that will save space. You’ll need 250 of pressure hose is you open on doing breezeways.

It’s a hot water unit.

That doesn’t change any of my response. Get some of that hot water on a bulb on the sprinkler head in a breezeway and he’ll have more water than he knows what to do with :slight_smile:

I’m referring to concrete. You can fly with hot water.

I’m with you. I had hot water once. I couldn’t clean any faster with it. Still gotta rinse walls and that’s where the sprinklers heads are

Do they make a remote to shut off hot water?

If they don’t, I’m sure your could make one.

Only place we use hot water is dumpster pads, and maybe gum removal

I only use warm water (80 degrees) indoors for Any trash grease stains along with degreaser. If washing the walls I agree, cold water.

I have 300 feet of hose. I just keep an extra hundred on the side. Most hose reels only carry 200 and I wouldn’t want to push water through more than 200 feet of hose when I’m doing flatwork otherwise. That extra hundred feet I just haul up to the top floor, drop down and then connect to the truck hose and pull what I need from there.

80 degrees isn’t going to help with grease, but it’s not going to hurt siding either. That’s basically average temp of standing water in most Southern states.
