I bought this to pick up dust and dirt from grinding a concrete slab that was coated with ceramic tile putty. It looks like it will work. The design is good, but there is no "collar" large enough to put on a ryobi collar. I never used it before we hit the ground running. Another issue is that there is no adapter for 2-1/2" industrial vacuum cleaner hose, only 1-7/8" hose with no adapter. I'm not sure I'll be sending it back to continue playing with it to see if I missed something.
