I just picked one up, has a shoe horn at the end of it too. But, what is its purpose? Other than removing any surface lint and such. It seems these were more popular well, when DE's were popular, around that time frame.
Brushing not only removes light surface soil, it also lifts and restores the nap of fine woolen fabrics.
Is there an advantage to the clothes brush over the sticky roller (other than the wasted disposable roller tape)?
