If you've cleaned the roller brush, replaced the belt, and your Oreck XL vacuum still won't pick up debris and emits a smell while running, there could be several possible issues:
Clogs or Blockages: Even though you've cleaned the roller brush, there might still be clogs or blockages elsewhere in the vacuum's air pathway. Check the hoses, nozzles, and filters for any obstructions and remove them if found.
Worn or Damaged Roller Brush: Despite cleaning the roller brush, it might be too worn or damaged to effectively pick up debris. Inspect the roller brush for any signs of wear, fraying, or damage. If needed, replace the roller brush with a new one.
Incorrect Belt Installation: Ensure that you've installed the new belt correctly. The belt must be properly aligned and tightened for the roller brush to function correctly. Refer to the user manual or Oreck's official guidelines for the correct belt installation procedure.
Belt Tension: If the belt is too loose or too tight, it can affect the roller brush's performance. Check the belt tension and adjust it according to the manufacturer's recommendations.
Motor Issues: A burning smell while running the vacuum could indicate motor problems. It's possible that the motor is damaged or malfunctioning, causing the vacuum's lack of suction and emitting a burning smell. In this case, it's best to contact Oreck's customer support or take the vacuum to a professional repair service.
Worn or Dirty Filters: If the filters are old or dirty, it can restrict airflow and cause a lack of suction. Make sure to clean or replace the filters according to the manufacturer's instructions.
Belt Slippage: If the belt is slipping or not spinning the roller brush effectively, it won't pick up debris properly. Check for any signs of belt slippage or damage.
If you've checked all the above points and still can't identify the issue, it's best to have the vacuum inspected and repaired by a qualified technician. Oreck's customer support can also provide assistance in troubleshooting and resolving any problems with their vacuum cleaners.
