I'm referencing my previous Dyson v6 here for context. has certain advantages: Good quality of cleaning, although I expected a little better; finally figured out how to prevent hair and other offal from landing up on the brushes; - Eliminated the majority of ergonomic issues, including needless locks. It's clear that they aimed to address several problems with earlier prototypes. - LASERS for light! This is awesome; I never imagined my own house to be such a slum. Contrast the following: The standard of construction has not increased throughout the years. The assembly of a Dyson is not flawless; there are plastic buildups. It's, well, weird how the Piezo element and auto mode work together. Well, it's impossible to design a handy mechanism for dumping rubbish, and the dust collector's volume isn't adequate to clean the apartment. It's unclear why.
