Cordless SEBO vacuum runs but suction is very weak compared to normal.

Safety first: Turn the vacuum off and remove the battery before clearing blockages.

• Empty dust bin: Remove and empty the bin. Check the bin inlet and cyclone shroud for compacted dust and hair; clean thoroughly.
• Clean filters: Remove the pre-motor filter and tap gently to remove dust. If washable, rinse under lukewarm water until clear, then air-dry completely (24 hours) before reinstalling.
• Check wand and nozzle: Detach the wand and look through it toward a light source. Use a rod or flexible brush to push out any clogs. Inspect the floor nozzle inlet for blockages.
• Inspect seals: Check the rubber seals around the dust bin and filter housing for damage or misalignment. Reseat or replace seals if they are torn or flattened.
• Test without accessories: Run the vacuum with the wand and nozzle removed, directly at the main inlet. If suction is strong there, the blockage is in the attachments; if still weak, the internal cyclone or motor fan may be obstructed and require professional cleaning.
