Interesting, for reasons I won't bore you all with yet, I had my Sebo X1.1 out today instead of the Vorwerk. It had a brand new bag in it. Normally, with a new bag, I can get a good inch of dust and hair in the bottom of the bag, but the Sebo has barely picked up much at all. Enough to the line the bottom of the bag with mostly cat hair, but certainly nothing compared to what I used to get up. Reassuring that, despite the softer brushroll, the Vorwerk was a worthy investment and is picking up more.
