Vacuum shows E6; suction is very weak or pulsing; motor sounds like it is surging up and down.

Safety first: Turn OFF the vacuum and remove the battery before disassembling any parts.

• Remove and empty dust bin: Detach the dust cup and fully empty it. Tap the sides to loosen compacted dust.
• Clean cyclone assembly thoroughly: Remove the cyclone unit. Use a soft brush or compressed air (lightly) to clear dust from the cyclone cones and mesh screens. Do not soak non-washable cyclone parts.
• Inspect wand and hose: Detach the wand and look through it toward a light source. Use a broom handle or flexible rod to gently push out any blockages. Check any flexible hose sections for clogs.
• Check floor head inlet: Look into the suction opening of the motorized head. Remove any large debris, hair clumps, or fabric pieces.
• Check seals and gaskets: Inspect the rubber seals around the dust bin and cyclone. Ensure they are seated correctly and not torn. Reseat the bin firmly until it clicks.
• Reassemble and test: Reinstall all parts and test on low power first. If E6 persists with clear airflow, the pressure sensor or control PCB may be faulty and require service.
