Are you talking about brushes that attach into a rotary hand drill chuck for cleaning? I would think that when you say `drill" these days, it is a cordless 16 to 18-volt powered portable drill.
I also assume these are for cleaning fabric seats or foot-well floor carpets or carpet floor mats.
i do know that they make 4" diameter brushes in various brush bristle softness or types that attach to dual-action buffers for cleaning. One thing to keep in mind is to get the type with a screw-in threaded shank that takes the place of the backing plate. The kind with the hook-and-loop (IE, Velcro) that attaches to a backing plate of the same diameter is subject to come off if you use pressure will cleaning, even if it is "industrial" hook-and-loop that "should" hold securely.
This question is related to a question I have been meaning to ask:
How many of you with Rupe`s Nano I-brid use the available accessory 50mm(?)(2") brushes for cleaning and is it effective or useful??
