Query: I really like this one, but...

I really do like this vacuum. I bought it when we lived in a 3-story townhouse with our 8 cats. It made vacuuming the multitude of stairs so much easier. I like it so much I bought one for my sister. But I really wish it had a brush attachment. When you're sitting on the stairs vacuuming you're so close to the moulding you can't ignore the hair/dust resting upon it. The crevice tool gets some of it, but not all. A brush would make this vac perfect. BTW, don't use it to vacuum sheet rock dust as my husband did BEFORE I knew what he was doing. Hopefully a new filter will help the suction. ;o)
