In the first pic you can see the floor machine.Its a special low speed (175rpm)Its a wet process so youre pretty much wet sanding with diamond pads just like I use on granite but these are ridgid and made for floors.This machine can also polish concrete with a diffrent attachment on it.This floor didnt shine up to good b/c its a low quailty commercial travertine and its a very light color so you can only do so much with it.This can also be done on a tumbled floor with out the de lip process.So on those floors all you can do is clean seal and polishThat's way too cool, I may be buggin ya for some more info soon 8)
