I bought the Dyson Piston 16 at €899, replacing my old Dyson V11 Absolute which I had used for several years. Although I expected several improvements due to the newer model, I was not satisfied. It seemed heavier to use and, in addition, the noise at high intensity was more pronounced compared to the V11. In terms of suction, they seem similar to the V11 without major differences in performance that would justify its much higher price. Furthermore, the built-in LED lighting, which was also present in the next models after mine as well as in the new Piston 16 model for detecting dust, is a useful addition, but in practice, I did not find that it changed the cleaning effectiveness compared to the previous model. Also, the special adapter that attaches to bend the wand and vacuum under sofas, furniture, etc., is not included in the package of the new model nor can you buy it as an add-on, while in previous and cheaper models, e.g. V11, V15, it exists. Dyson, you disappointed me!!! This particular purchase left me somewhat disappointed as I did not feel that the user experience was substantially improved!
