Hi All,
I have always wondered, why is it so important to empty Dyson when the dirt reaches the Max line? If the machine does't have any loss of suction then surely this won't harm it at all. I have had Dysons since 1999 and most of the time always go over the max line without any problems.
My DC04 which is 7rs old always gets the dirt going over the mark line and I continue to use it until I can be bothered to empty it, this has not caused any problems with it.
Occasionally I have had the odd long bit of hair go onto the Pre motor filter but this happens even if the machine isn't full. Had this quite bad on the DC05 cylinder which would have literally chunks of hair on the pre motor filter by the time it came to emptying it.
