Following the item on "Cafe", I was keen to try the non-tangling aspect of this... but the non-tangle head is huge and heavy, and on first run didn't seem to pick stuff up well. It's not getting the carpet tassle threads that my dog chews and leaves lying around... particularly why I wanted the no-tangle thing!The second head is much lighter and easier to use, but seems wasteful to not use the main component. I'm going to see if I can return it all.
