A missed point
is that clogged filters are one reason why a Dyson cleaner will be discarded in favour of a newer model. So many consumers never, ever wash the filters and then replace the whole cleaner. Even when washed, some filters are good for nothing and require replacement.
So, without this built-in "failure device", the cynic within me simply has to question what else Dyson will be doing to ensure their new machines continue to breakdown in a timely fashion so as to necessitate a future purchase.
