Step 2: Check for Blockages

  1. Remove the wand and brush head from the main body.
  2. Inspect the wand, brush bar, and inlet for obstructions or debris.
  3. Clear any blockages carefully using a long, thin tool or cloth.

Step 3: Clean or Replace the Filter

Dirty filters can cause suction loss. Remove the filter according to your model’s instructions and inspect it.

If it’s visibly dirty, rinse it with water and let it air dry completely before reinstalling. If the filter is damaged or very old, replace it with a new one, such as the 3Pack Pre Filters Replacement (asin=B091D4YRYG).

Step 4: Empty and Check the Dirt Bin

Ensure the dirt bin isn’t full or improperly seated. Empty it if necessary, and confirm it clicks securely back into place.

Step 5: Test the Vacuum

Reassemble all parts and turn on your Dyson. Check if suction has been restored. If not, proceed to inspect the motor or consider professional servicing.
