      If your Oreck Vacuum Cleaner isn't picking up dirt, several issues could be the cause. Here's what to check: * The filter bag might be full - replace it. * The nozzle or intake pivot could be clogged - clear any obstructions. * The bag tube might be clogged - clear any obstructions there as well. * The bag pores could be clogged with fine dust - change the bag. * The belt might be broken or stretched - replace the belt. * The revolving brush is not even at both ends - check the bearing seal, ensuring the words “OLD” or “NEW” are at each end.
