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

Safety first: Switch OFF and remove the battery before cleaning filters.

• Empty bin: Remove and empty the dust container.
• Clean filters: Take out pre- and post-motor filters. Tap gently to remove dust. If washable per Sencor manual, rinse with lukewarm water and dry completely (24 hours) before reinstalling.
• Check wand and hose: Detach the wand and any flexible hose. Look through them against light and remove any visible blockages using a non-sharp tool.
• Inspect nozzle: Check the floor nozzle air channel for obstructions and clean thoroughly.
• Test suction at main body: Run the vacuum with the wand removed. If suction is strong at the main body but weak at the nozzle, the blockage is in the wand or nozzle.
