Vacuum has very weak suction but runs normally with no error code.

Safety first: Turn OFF the vacuum and remove the battery before cleaning.

• Empty and clean dust bin: Remove the dust container, empty it, and wipe the inside with a dry cloth. Tap the cyclone gently to remove packed dust.
• Clear blockages: Detach the wand and tools. Look through each piece and push out any clogs with a blunt rod.
• Clean or replace filters: Remove the pre‑motor filter and HEPA filter. Tap off dust and rinse if allowed. Replace with genuine OKP filters if they remain dirty or deformed.
• Check seals: Inspect the dust bin gasket and any O‑rings. Replace the dust bin gasket if cracked or flattened.
• Test suction at motor inlet: With the bin removed (if design allows), briefly run the motor to feel suction directly at the inlet. Strong suction here but weak at the floor head indicates a blockage or leak in the attachments.
