I purchased my first (Tineco), and it will be my last, over two years ago. Previously, I had purchased a Dyson (twice), and as all of know this cordless vacuum cleaner is pricey. But I took a chance and bought the Tineco (#10, maybe) because it was cheaper, and after 2 years it died. The batteries (both) no longer held their charge. After several attempts of attempting to recharge both batteries failed, I had to junk it. With this model, it was big, heavy and clumsy. This Chinese company is it rush to into the market produced a lousy imitation. In this case you pay for what you get.
