I had a shark befor that I loved. I am a seamstress and therefore I have lots of threads. So the vacuums came out for pet hair, and figured that’s what I needed. I unfortunately read the comparison reviews snd went wuth a different vacuum. It wasn’t long til I regretted my decision. I was in the hospital, not sleeping, and watching the stratos commercial over and over. I had to have it. As soon as I arrived home, I ordered it. I will never own anything but a Shark.
