What can I check? Answer: Check the inner and outer circular filters and the post-motor filter for debris. The inner and outer circular filters are the lower half of the dirt container. These can be rinsed. The post-motor filter is covered by a plastic grate just below the dirt container. Check the upper tank’s primary separator. This is the grey plastic part of the upper tank (it’s covered in louvers). You can simply unscrew it and rinse it with water. Note: Failure to properly maintain the filters could result in damage to the motor. A clogged hose may also cause the unit to sound abnormal—see our “PowerForce Clearing Clogs” FAQ if necessary. If you still experience excessive noise at this point it might be best to take your vacuum to a technician.
