I'm not sure who measured this brush roll and said it was 10 inches. 10 inches isn't even the inside edge of the roller to the other inside edge (you can see in my second photo). This brush roll needs to be measured from the outside to fit your vacuum properly! ! If it were indeed a 10" brush roller as stated in the sizing questions, it would fit my Bissell Powerforce Compact vacuum perfectly! My other broken roller measures exactly 10" from the outside to the outside. Very disappointed with no exact measurements or description to buy this roll On the plus side, it arrived a day early!
