I thought the Hoover I had was good but I was very surprised by how excellent of this WindTunnel 3 High Performance. My carpet looked clean but then I vacuum it and I got a surprise by how much dirt and pet hair I got out. I keep doing it every day for a while and the carpet started to look newer and smell fresh without using any product. I will recommend for anyone who has a carpet with or without having pets. I love the design, how the attachment fit for storage in the unit, the how easy is to use and maintain clean and store all together. I started using Hoover decades ago because the HEPA filters, notice a huge diference in my allergies. Thank you.
