16” would be good for 4gpm and I prefer no casters because I found I can get into tighter places and they end up getting in the way. And when doing sidewalks I found the kept falling off the side of the sidewalk.
Ok, all I can comment on is the caster thing. A 16” without casters will ‘float’ like a hovercraft, and in my limited experience will be lighter and easier to use, especially if you are doing sidewalks where it meets grass, etc.
If you’re doing large driveways and parking garages, then yeah…casters come in handy.
BTW It’s ‘4/4’, not 4x4. That makes us think you are getting a 4wd truck.
The Ultra Clean is a good model and $200 less than the Eagle, but same company.
Funny you mention that, I have secretly been hoping to clutch on this new venture so i can get a new 4x4 truck
I also do tile and carpet so tile in house the tools tend to get stuck on some tiles and its like bench pressing for 2 hours straight, So i like thinking of the fact there will be so much pressure it will hover, sounds a heck of a lot easier
I’m just going on my local PW shop, their Eagle is over $600, the Ultra $450. I haven’t priced online lately.
Surface cleaners have interchangeable nozzles, you can customize pressure and fan degree by changing them out. I had a 4/4 and the included nozzles made it want to fly off like a bottle rocket, so the guys on here suggested another size to keep things manageable.
