Airduct Blocked
Xiaomi cordless vacuum Airduct Blocked: airway obstructed
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On Xiaomi Mi Vacuum Cleaner G9 and G10 cordless stick vacuums, the Airduct Blocked prompt under Airduct Alarm indicates an obstruction in the dust compartment, extension rod, or roller brush head. Empty debris below the MAX line, clear the airway, and clean and fully dry the HEPA filter.
Safety first
Stop and check this first
- Never operate the cordless vacuum without the pre-filter and HEPA filter installed, never reinstall a damp filter, and never bypass any filter-missing or airway protection switch.
- Do not open the vacuum body, motor housing, lithium-ion battery pack, or charger; if the battery pack feels hot, looks swollen, or emits smoke after a blocked-airway stall, stop immediately and contact a professional.
Safe checks you can perform
- Empty the dust compartment below MAX and inspect the main suction port
- Clear the extension rod and smart sensor floor brush head airway
- Wash and thoroughly air-dry the HEPA filter element and pre-filter

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Vacuum pipeline seal and airway sensor inspection by Xiaomi after-sales service
What they doThe technician inspects internal airway seals and pipeline joints for cracks or air leaks and verifies the airflow sensing circuit responsible for the Airduct Blocked prompt on Mi Vacuum Cleaner G9 or G10.
They must show youthe damaged seal or internal duct obstruction found during teardown and the display operating without the Airduct Blocked warning.
In writingthe airway inspection findings for your Mi Vacuum Cleaner G9 or G10, any seals or duct parts serviced, and the post-repair suction verification.
Official after-sales diagnosis of the main suction motor assembly
What they doWhen Airduct Blocked or reduced suction persists despite a clean dust compartment, extension rod, floor brush, and dry HEPA filter, Xiaomi after-sales service checks the powered-off motor assembly for physical or electrical damage.
They must show youthe condition of the inspected motor assembly and the restored airflow test across Eco, Standard, and High Power modes.
In writingthe motor diagnostic report, the repair or replacement performed under Xiaomi service guidelines, and the warranty coverage on the repair.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Empty the dust compartment below MAX and inspect the main suction port
- Who:
- You, with the Xiaomi stick vacuum powered off and unplugged from its charger.
- How:
- Open the dust compartment on your Mi Vacuum Cleaner G9 or G10, empty all collected dirt before it exceeds the MAX line, and inspect the suction port of the main unit to remove any trapped lint or debris.
- Result that matters:
- Dust compartment cleared below the MAX line and main suction inlet completely open.
- If restarting the vacuum clears the Airduct Blocked prompt after emptying the bin, overfilling or inlet debris was the cause.
- If the Airduct Blocked prompt returns with an empty bin, detach and inspect the extension rod and roller brush head next.
- Evidence to keep:
- Photo of the emptied dust compartment below the MAX mark and the unobstructed main suction port.

Clear the extension rod and smart sensor floor brush head airway
- Who:
- You, disconnecting the attachments while the vacuum is switched off.
- How:
- Detach the extension rod and the smart sensor floor brush head, look through the tube to remove any lodged paper or hair balls, clean the roller brush neck, and reconnect all pipeline joints firmly so there are no air leaks.
- Result that matters:
- Unobstructed passage through the extension bar and roller brush neck with tight, leak-free couplings.
- If removing a blockage from the rod or brush head restores normal suction and clears Airduct Blocked, the obstruction was in the attachments.
- If both the rod and roller brush head are clear but Airduct Blocked persists, inspect the HEPA filter element and pre-filter.
- Evidence to keep:
- Photo looking through the clear extension rod and the cleaned roller brush inlet channel.

Wash and thoroughly air-dry the HEPA filter element and pre-filter
- Who:
- You, following Xiaomi's filter maintenance instructions.
- How:
- Remove the HEPA filter element and pre-filter from the Mi Vacuum Cleaner G9 or G10, tap out loose dust, rinse them with clean water, and let them dry completely in a ventilated area before reinstalling, or install a new filter if Replace the Filter is shown after one year.
- Result that matters:
- Clean, bone-dry HEPA filter and pre-filter properly seated inside the handheld body.
- If suction power recovers and Airduct Blocked disappears once the dry filter is installed, a clogged filter triggered the alarm.
- If Airduct Blocked or weak suction continues with a clean dry filter and clear airway, power off the unit and contact Xiaomi after-sales service.
- Evidence to keep:
- Photo of the cleaned and fully dried HEPA filter element and pre-filter prior to reinstallation.

What it means
Xiaomi Support's official Mi Vacuum Cleaner G9 and G10 Error Codes reference (KA-09374) and Mi Vacuum Cleaner G10 troubleshooting guides (KA-07618 and KA-107667) document the Airduct Alarm displaying Airduct Blocked when airflow is restricted in the dust compartment, the extension rod, or the roller brush head. The display can also show Replace the Filter under Filter Replacement Tips once the filter reaches its one-year service life. Other Xiaomi cordless stick vacuum models may differ in screen prompts, and an Airduct Blocked message alone never proves that the suction motor or internal sensor is defective.

- Clogged HEPA filter element and pre-filter or expired one-year filter lifePossible
Fine dust saturates the HEPA filter assembly and pre-filter after repeated cleaning sessions, or the filter has reached the one-year Replace the Filter interval.
