This hose is compatible with earlier SEBO Airbelt D4 vacuum models without a brush roller switch on the handle (typically purchased before August 2022, with this switch located on the power head).
It is not suitable for newer D4 models (purchased since August 2022) that rely on a handle switch to control the brush roller, as using this hose will remove the ability to turn the brush roller off. Please refer to the updated hose or speak with your local SEBO Dealer about which hose is right for you.
This part may be covered under warranty. Contact your local SEBO dealer to check eligibility and begin a repair or replacement.
