BissellLift-Off Model 3750 Upright Vacuum Roller Brush Aftermarket Part # B104

Fit great

Installed it, it didn't fit quite right and stated rattling. It damaged my plastic bottom to the vacuum (melted several of the thin supports) and was worse than the one that I'm replacing. The side opposite the belt didn't have a barring like the belt side and didn't fit in quite right.Returning this and buying a genuine OEM replacement.

works great, perfect fit. couldn't believe the difference

Fit perfect in my vacuum which now is working great.

Works great good fit
