You just stretch and pull open front the long edge and it's like a shower cap for your broom. They work good for trapping hair and dust bunnies. Even better for dusting the baseboards and getting cobwebs out of the corners. So much better than just sweeping.

I've been in the cleaning business for the past 2 decades before retiring and I wish I had these way back then. They work great at attracting more hair and dirt than without them. Put them on a broom or a flat dust mop. They will increase their cleaning power.

The thing I hate most about sweeping is the dust that gets hung on the broom. These slip over the broom nicely and it is so easy to take them off and throw them away. It's left me wondering "where has this been all of my life?"
