Because I wanted a small device, I must resign myself to the low volume. Why should it not rinse without evtl.stromführende parts on the underbody to wet, I do not understand, probably one may not immerse the cup. It served its purpose, and the foam is as desired. To avoid standby, I unplug when not in use both parts, a power off feature would be desirable, therefore, a star less. , ,
