what to keep
I would hang on to the electrolux, Miele, and Sebo models for sure. I would get rid of the Dysons, but admitedly, I'm a bit biased, I don't like bagless vacuums. Does your apartment provide any kind of storage unit? Mine does and I actually put my wet dry vacs in there, since those are not vacuums I would use for regular cleaning. Actually the floor was quite dirty in there, I used my Lindhaus hf6 to clean it.
