Well, first to "sleepdoc"
My humble apologies for upsetting you so much. I shall expound: I have use 4 of these cleaners, now, because I had to. One was brand new... used it to clean a mess in a sick friend's house. It was fair... and loud. The other uprights DID scratch a marble floor, (I didn't do it). They both clogged, leaked dust (the bag promises to be super clean), It was heavy, didn't pick up that well, (and were used on thin commercial carpeting commony found in churches.
As you know, I am HOOVER all the way. However, i"ve always supported those who like others. I'll show pictures of some of my cellar dwellers (Kirbys, GE, etc. I tend not to bash anyone or their preferred machines. So, Sleepdoc, I shall not upset you anymore. Peace to you.
John
