Floor grinding machines

[IPACA9]

OK. I'm confused. I see that people are using a diamabrush pad I guess that's been added to a floor polisher but when I walent to my tool rental place they had an actual floor grinder that has a smaller head. What am I to go with? They've applied a sealer to my garage floor so here goes the grinding.

Your local tool rental store likely does not have the Diamabrush system.
Besides a hand-full of rental places scattered across the USA , that we supply, your best bet is The Home Depot (rentals).

At any rate , as long as they are supplying a diamond grinder, you should be ok.
