This cleaning base fits the
This cleaning base fits the S8 model if you cut off the three little plastic tabs on the bottom at the back. It’s easily doable with a utility knife, Dremel tool, wire cutters, or a heavy duty enough pair of kitchen shears. You could also wiggle the tabs back-and-forth with a pair of pliers until they pop off due to stress.
I bought this because the base of the S8 was expensive and poorly designed I got this for $18, and it is better designed and fits better than the original S8 milk cleaning base. Honestly, this is the base that should be paired and packaged with the S8 units that are being sold.
