Vacuum has very weak suction even though the motor sounds normal

Safety first: Turn off the vacuum and remove the battery before cleaning filters.

• Empty the dust bin: Remove and empty the bin. Wipe the inside with a dry cloth.
• Clean pre-filter: Remove the pre-filter and tap it gently to remove dust. If washable per Proscenic instructions, rinse and let it dry completely before reinstalling.
• Clean or replace HEPA filter: Tap off dust; replace the filter if it remains heavily clogged or damaged.
• Inspect cyclone: Check the cyclone holes and channels for fine dust buildup and clean with a soft brush.
• Check seals: Inspect the rubber gasket between the dust bin and main body. If torn or deformed, replace the seal or dust bin assembly to restore suction.
