Vacuum runs but suction is weak even with fully charged battery and no error code displayed.

Safety first: Turn off the vacuum and remove the battery.

• Inspect the dust bin for cracks, especially around the latch and connection to the main body. Replace the dust bin assembly if cracked.
• Check the rubber seals between the bin, cyclone, and motor housing. Look for flattened, torn, or missing gaskets.
• Clean seals with a dry cloth and ensure no debris is trapped between mating surfaces.
• Reassemble carefully, making sure each component clicks firmly into place.
• If suction is still weak, inspect the extension tube and floor head for micro-cracks or loose joints that could cause air leaks; replace the affected part.
