but it is the "Plus" system - at least that's what it says on the box. ;-)
and above I meant "empty daily", of course.

whether it is the "plus" system or not is beyond my knowledge. i am absolutely satisfied with the cleaning performance. it runs during the day in the unmanned flat. in the morning, a quick pile up and in the evening EVERYTHING is clean, even under the table. the small corners, narrow spaces and behind the doors are vacuumed by hand every week in a few minutes and that's it. the dust container is a little small for a large flat, so it needs to be cleaned DAILY.
I am completely satisfied with it. recommendation -> buy.
