I find that it works very well when you are using the Furmantor shampoo and conditioner because you have to work them into the coat for at least 5 minutes, so it can cut that time down a little bit.a zoom groom will only benifit them in a bath to massage shampoo in. I wouldnt recomend it for anything else, also do not use a furminator. it will do nothing one those breeds. a slicker, undercoat rake and comb is the essentials.
