Rozichka Ето и оригиналния отговор от customer service на VAX:
".....the filter in the machine will need regular maintenance and washing every couple of weeks, the filter is there to prevent dust travelling to the motor and the HEPA filter is designed to trap the dust.
The blockage light is very sensitive but if there is suction on the machine you can ignore this.
You may wish to consider purchasing a new set of filters ...."
