Setup and Installation

This brush roll is designed for Kenmore upright vacuum cleaners that use a flat rubber belt and have U-shaped end caps on the brush roll. It is critical to verify that your existing brush roll has end caps identical to those shown in the images below for proper fitment.

Step 1: Prepare the Vacuum Cleaner

  1. Unplug the Vacuum: Disconnect the vacuum cleaner from the power outlet.
  2. Access the Brush Roll: Lay the vacuum cleaner on its back. Locate and remove the bottom plate or cover that secures the brush roll. This usually involves unscrewing several screws.

Step 2: Remove the Old Brush Roll

  1. Remove the Belt: Carefully remove the flat rubber belt from the motor shaft and the old brush roll.
  2. Extract Brush Roll: Lift out the old brush roll from its housing.

Step 3: Verify End Cap Compatibility

Before installing the new brush roll, compare its end caps with your old brush roll and the images provided. The brush roll features distinctive U-shaped end caps.

Step 4: Install the New Brush Roll

  1. Place New Brush Roll: Carefully insert the new brush roll into the vacuum cleaner's housing. Ensure it sits correctly in its designated slots.
  2. Install the Belt: Loop the flat rubber belt around the motor shaft and then around the new brush roll. Ensure the belt is properly seated and tensioned.
  3. Reattach Cover: Replace the bottom plate or cover and secure it with the screws removed earlier.

Once installed, gently rotate the brush roll by hand to ensure it moves freely and the belt is correctly aligned.

Ensuring Proper Function

After installation, plug in the vacuum cleaner and test its operation. The brush roll should spin freely and consistently when the vacuum is turned on. Listen for any unusual noises or vibrations, which could indicate improper installation or a misalignment of the belt.

  • If the brush roll does not spin, check the belt for proper placement and tension.
  • Ensure no debris is obstructing the brush roll's movement.

Maintenance

Regular maintenance of your brush roll helps maintain optimal vacuum performance and extends the life of the part.

  • Hair and Debris Removal: Periodically inspect the brush roll for tangled hair, threads, or other debris. Use scissors or a seam ripper to carefully cut and remove any obstructions.
  • Belt Inspection: Check the flat rubber belt for signs of wear, stretching, or damage. Replace the belt if it appears worn to ensure consistent brush roll rotation.
  • End Cap Check: Ensure the end caps are free from debris and are securely seated.

Always unplug the vacuum cleaner before performing any maintenance.
