No idea if it'll fit the G110 (but it *is* just velcro backed, so it wouldn't surprise me).
But I dunno if a velcro back is the way to attach such a brush :think: The ones I use on my Cyclo (which would also work on a PC) *screw* on in place of the regular backing plate, and when I lean on the machine I'm glad they mount that way. I somehow suspect that you'd have to be a little gentle with the velcro mounted ones, not that that would necessarily be a bad thing.
Guess my answer is pretty much just :nixweiss
