Review on Efficient Dust Brush Attachment for 1 1/4 Inch Generic Vacuum Cleaner by Lisa Black

I bought this brush solely because of the length of the bristles. It allows me to get rid of the dust that gets trapped deep in the slots of my filter. it meets my needs but not as good as an add-on to the vacuum The bristles are not stiff enough to not bend when the vacuum is turned on The bristles should be stiffer.
