Braun CCR 6+2 cleaning station refill cartridges are compatible with Braun SmartCare cleaning stations. These cartridges work with all Braun Clean&Charge units, which includes the models used for Series 9 shavers, such as the 9291cc purchased in 2019. So, you can use these cartridges for your Braun Series 9 shaver (9291cc) without any problems.

The cleaning station is compatible with Braun Series 5 shavers that are labelled as CC models (Clean & Charge), i.e. those with an automatic cleaning station. Solo Series 5 models without CC labelling are not compatible as they lack the necessary chip to communicate with the cleaning station. The refill cartridges are suitable for all Braun Clean & Charge stations.
