1) Empty the Dyson is not much fun if you do not want to suffocate, it must be put in a bag tightly closed and shake. After that, he will remain toutjours dust in and on the edge. If you take the trouble to wash them, it must be dry (wait plx hours) before you can use the Dyson. In fact it is more laborious than just bp dust bag traditional aspi.
2) There are 2 filters, filter remains clean all the time (that is precisely what it boasts in pubs). You will understand why there is all clean Temp. In fact there is a second hidden filter that takes all the dust, the latter of which is you never talk about it after every aspi's disgusting. In the manual, it is recommended to clean 1 time per month. In practice, it is so disgusting that you have to do it very often. In addition you must wash and let dry for 24 hours minimum.
Verdict, well it sucks, it makes noise bp, there is a clean filter, but one that is hidden dirty all the time. The dump is a dirty job (unless you are not sensitive to dust and you do not care in the dirt that remains and continues in the aspi), clean the second filter is a hidden nightmare (opening the hatch is not easy and more).
In the end, you spend almost as much time cleaning it than to use it.
Let's say Mr. Dyson was able to turn your work (maintenance fussing) by suction. You touts and he does not say that you go to keep toast power aspi like new.
