first unplug,then remove belt access cover take out old belt and clean area then flip cleaner on side access up. Then remove silver screw in red plate and remove from bottom, then depress on side of floor brush and remove brush. Now, what I did was take off floor brush belt then turned belt side ways to slip between pully and side of cleaner, then pushed through with skinny screwdriver till I could get hold of it then pulled through and put on pully and around belt drive then replaced brush belt and brush and put every thing toghther. and as a side note I was not happy with the answers from bissel they just wanted to get my personal info so even though I'm tired I just wanted to post this to show my personal dissatifaction with the bissell company because who makes and instructon manuel that doesnt show you how to do the very basic needs of their product shame on you money grubing bissel
