I tried the Furminator that I use for my cats on Sweep when we'd had her about a month, and she gave me a nice black eye for my efforts. I don't think she meant to get me; I must have hit a tender spot, she reacted, and I got muzzle-punched/grazed by her tooth in the process. In my opinion, it's too much for their thin skin and bony bits, so I stick with the zoom groom, which she seems to view like a massage.
And, yes, she is currently a sheddy mess, even with daily Missing Link and coconut oil. Thank God for my Roomba!
