At first I wanted to buy myself a smaller device, but have taken on the basis of ratings, distance therefrom. First, the device is not too great, but you're glad if you ewas more room. It was absolutely convincing when cleaning and the operation and would opt again for it. It's reasonably quiet, easy to use and has 3 switch settings that are still useful because the Pollution degree varies. It is easy to clean, all in all a great device.
