The narrow brush head is too small and not strong enough to treat pet fluff/hair. We just bought a new/used house that was home to the loveliest cat. Obviously I didn't expect her to clean the dryer and vent after leaving as I like to inspect/clean it myself. It's a great idea, but it clogs with every movement and you have to unscrew it from the main body to free it for reuse, and it's too flexible to stay centered in the corner where the pipe meets another large lint pipe at the back meets. Dryer. Spend a little more on yourself than I do on myself.
