I am trying to find the thread that vacuumfacts says that all his reviews have the testing procedures. I tried to find what post it was on. Then I looked on vacuum facts account for what post it was on. Then I found out that I am unable to view his account because he restricted my access to it. Anyway, I want to appologise if this is on the wrong thread, there is so many Dyson based threads and I can never remember what one I need to post on. I will watch all your reviews vacuumfacts and tell you all the errors I see in your testing. Evenly spread, how is that specific enough. Brush over twice, what brush and how stiff is it, how hard are you pressing down on it, is the back and forth motion consistent. 0.5 meters per second, how do you measure that. How is Dyson zorb exactly a replacement to real dirt. Dyson zorb has to be slightly damp meaning it is not going to work properly. I notice the nozzle is not being guided perfectly straight, how does this effect results. I could go on and on, however I know that it is not worth it.
