Product details
Style 15 belts for Dirt Devil uprights, part 3SN0220001, two to a pack, listed for the Dirt Devil 3109.
The belt carries drive from the motor to the brush roll, and it is the part that quietly decides how well the machine cleans carpet. As it wears it lets the roll turn slower than the motor intends, so the bristles brush the pile instead of agitating it. The pattern owners describe is a vacuum that still sounds powerful and still picks up from hard floors, but leaves pet hair and grit sitting in carpet after several passes.
Check the belt whenever pickup falls off on carpet, and replace it if it looks glazed, slack, or narrower in the middle than at the edges. Fitting takes a few minutes with the sole plate removed, and the spare belt in the pack means the next change costs nothing but time.
