The vacuum has very weak suction even with a fully charged battery.

Safety first: Turn OFF and remove the battery before disassembly.

• Check for blockages: Detach the wand and nozzle. Look through the wand and nozzle neck for obstructions and clear them.
• Clean cyclone: Remove the dust bin and cyclone unit. Disassemble as per the manual and remove compacted dust from cyclone cones and channels. Rinse if allowed and dry completely.
• Inspect seals: Check rubber gaskets around the bin and cyclone for damage or misalignment. Reseat or replace if worn.
• Test handheld only: Run the handheld unit without the wand/nozzle. If suction is strong, the restriction is in the attachments.
