How often should the bars be changed out? What are some signs that it needs to be replaced?
I’m finding that they need to be replaced semi often. Even when they haven’t been hit or bent. The surface cleaner just kinda loses its power gradually. A new bar fixes it even though it’s not apparent why. Is this normal? What’s the underlying reason? Maybe it’s losing its symmetry.
All whisper wash. One 20”, 24” and a 31”.
The 20” is 2yrs old and is working great. The 24” is about 6 months old and spins freely but doesn’t have as much lift as it’s had before. I changed the nozzles with no luck. Changed the entire bar and it’s working great again. I’m having some issues with the mini mondo. I think it’s defective. One bar spins more freely then the other and I’ve replaced both swivels. So basically we are talking about the 20” and the 24”. New bars seem to bring new life to them. Even when they’re not visibly bent. They have some rock dings and dents and rounded corners but nothing that I would think should noticeably effect performance. So I’m taking it that out of the people in this thread it’s not a common issue?
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.
