I get a fat boy and 200ft of 1/2 AG hose . Since your not planning on doing roofs bigger is better. And 800psi AG hose is almost impossible to destroy pump is about $200 on eBay. Hose is also about $200 decent reel $300 fitting poly gun and nozzles $75 since you already have a tank and battery . You could probably do it for half that number buy getting cheaper stuff but it wouldn’t be built to last.
I hate 12 volt but I was very surprised at how far and how much that fat boy could shoot. It’s every bit as far as my aodd pumps. If you want to max out the pump use 5/8 or 3/4 hose . But that’s some heavy stuff to drag around. A fat boy with 200ft of 3/4 hose will shoot further than my air pumps. I had one as a backup pump once I couldn’t believe the distance on that thing
shooting straight up you’ll get about 30-35’ with right nozzle. But you don’t want to rinse with it. It actually is only pushing about 4 gpm at 60psi. You’ll probably want to turn it up to about 80. That seems to be the sweet spot.
@Chesebro i thought about building my own softwash unit but bought the bandit instead. Like you I don’t do roofs and use it primarily for concrete, stone and pavers. If you can afford it it’s a nice setup with the pump under the reel and everything contained in a small foot print. My accumulator didn’t last a season but I was able to change it out in seconds.
Dont take this the wrong way brock, but this is bad advice. He wants a softwash system, something to go hotter than an xjet is even capable of… so it doesn’t really help him.
Although the xjet is great dont get me wrong, but I’m in the same boat as him and I already own an xjet. I also want to build a softwash system in the spring.
There’s lots of different ways to get to the same spot. You can get as hot as 50/50 with x-jet I believe. That would put you at roughly a 6% solution hitting the target. That’s pretty hot in most situations.
The only way your getting a 50/50 mix with an xjet is to either use a 2gpm machine or throttle down a larger machine.
Also its not practical to clean a roof with an xjet so having a “softwash” system/machine is still beneficial.
Having a 12v or other SW system is definitely a good idea. It’s just not the only way. I know of at least one veteran here that uses an x-jet to wash roofs.
