I’ve had two very expensive vacuums and have not been pleased with either of them. I was excited to get a different brand but also a little skeptical. This Shark Vertex more than exceeded my expectations! It is by far the best vacuum I’ve ever owned and I will never go back to a different brand. It cleans phenomenally and gets into tight spaces easily. If you’ve had it with expensive but under preforming vacuums, you will be so pleased with the Shark Vertex!
