Cordless vacuum has very weak suction even though the motor sounds normal

Safety first: Turn OFF the vacuum and remove the battery pack before inspecting seals and filters.

Step-by-step checks:

• 1. Empty and reseat the dust bin: Remove the bin, empty it, and reinstall carefully. Ensure it clicks fully into place and that the latch is secure.
• 2. Inspect bin gasket: Look for a rubber or foam gasket where the bin meets the main body. Check for tears, deformation, or missing sections. A damaged gasket will cause major suction loss.
• 3. Clean or replace pre-motor filter: Remove the pre-motor filter and clean according to the manual. If it remains discolored or deformed after washing and drying, replace it with a compatible Amazon Basics filter.
• 4. Check cyclone housing for cracks: Examine the plastic cyclone cone and surrounding housing for hairline cracks. Cracks can cause air leaks; the cyclone assembly may need replacement if damaged.

When to stop: If suction remains weak after sealing and filter checks, internal seals or the motor fan may be damaged, requiring deeper disassembly.
