Maintenance
Replacing the HyClean Air TU Vacuum Bag
The HyClean Air TU vacuum bags are designed for hygienic, dust-free disposal. Replace the bag when the bag indicator on the canister unit signals it is full, or when suction power noticeably decreases.
- Ensure the vacuum cleaner is unplugged from the power outlet.
- Open the dust compartment lid.
- Carefully remove the full vacuum bag. The ComfortFit technology ensures the bag opening automatically seals to prevent dust escape.
