Helpful answer

As far as I know, the AC4221/11 appliance is the successor model to the AC4236/10 appliance. The AC4236/10 model has been sold in Switzerland since January 2020, the AC4221/11 model since January 2025.
The cleaning performance of the newer model is said to be slightly better, but the filters, which have to be changed annually, are more expensive than those of the predecessor model.
