I bought this vacuum 10 days ago. I had vacuumed with my other vacuum 4 days before and got up a load of dog hair and thread. I put this vacuum together and tried it out. It got dog hair but also got a lot of embedded dirt. I was totally amazed.  I am seeing colors in the carpet that I haven't seen in years.  We have red dirt that sticks and makes everything terra cotta colored. Add thread and white dog hair from 3 double coated dogs . . .  I vacuum several times a week.  I love the vacuum but I'd wish it had come with the combo crevice tool/brush since I usually do a lot of dusting while I vacuum, plus use the crevice tool weekly. I don't like the crevice tool that came with the vacuum because dog hair wants to come out of the slots on the sides. Instead, I have to buy them separately.
