I have collected a lot of information about Dyson vacuum cleaners and have been observing these dynamics. After a lot of data and feedback, I have come to some conclusions and some misunderstandings in everyone’s perception: 1. The performance of the higher version is not always better than the lower version, from V6 to V11, not all V11 performance is better than V6, for example, in terms of portability, V6 is much lighter than V11, which makes the hand vacuum cleaner much better to hold.
