I’m not that impressed with it but it could just be the defective swivels. I swapped them out and have some flatwork scheduled for Saturday to test it on. The worker was the first one to use it and he said the first 10min was amazing, then one bar stopped spinning fast. Swapped the swivel and then the other bar stopped spinning as fast. With the bar spinning slower then the other you had to walk so slow we didn’t continue using it. Went back to the 20 & 24
Another issue was there’s not much clearance between the bars and housing. I did a gas station earlier in the week and rocks kept jamming between the bar and housing. Never had that problem with the other surface cleaners. It shouldn’t be an issue on most jobs as long as there is no rocks or you can blow them off prior. I didn’t notice any rocks before starting but it was dark and it’s old concrete with a good bit of aggregate exposed.
I’ll do you more testing in different situations and keep you posted. I would hold off for now.
