Many UK hospitals
have reduced the amount of vacuuming they do as it was actually thought to be unhygenic due to what could be breeding in the cleaner and the dust bags. Carpets have all but been eradicated, but also the method of vacuuming hard floors was considered liable to unsettle dust in a way that made it airborne, to the extent that dust-mopping floors has been favoured. Hospitals here also prefer paper hand towels over electric dryers, again for the belief of moving around germ-borne air. That is of course excluding Dyson hand dryers which have been able to make a presence in some establishments.
As for that video and as for the comments that the Dyson can be made to look more favourable should one choose to, it has to be remembered that these videos are little more that the results of, say, a survey, where comments and statistics are gathered in such a way as to reflect only the aspects which the commissioner of the survey wishes to convey to the 3rd party. The video here was completely biased in favour of the Bosch, and in normal usage no cleaner would be expected to cope with that kind of debris. Indeed with any cleaner, I would be inclined to sweep the area first.
But this does not mean I am standing up for Dyson either. One only has to review their own official videos to see they too like to show matters from a certain angle. For instance, those cleaners which in tests are mechanically moved back and forth, and cleaners dropped from a height continually. What does this prove? It proves they held their own during rigid factory testing. It does not prove they will hold out in 'normal' use. That, as we all know, is an entirely different way of testing the durability of anything.
