Purchased for use with Bissell Zing Canister (Vacuum Cleaner 2156A, Green Bagless). It is ideal and necessary for sucking dust and hair from all possible nooks and crannies. You can sanitize it after using it in the bathroom by soaking it in a solution of bleach and water (a teaspoon of bleach + 4 cups of hot water for half an hour, then let it dry overnight). The bristles do not discolour. Recommend!
