I use a DC33 and DC07 on occasion, recently purchased another Rainbow E Series from a thrift for $10 and was cleaning it today so I used the DC33. I've used it maybe 15-20 times since I last cleaned the filters around February. I'm not cleaning anything out of the ordinary, not getting an inordinate amount of dirt (if anything hardly anything). So I wash the filter and the water is black in the basin, like Rainbow water. Now the part I don't get is how come an 11 amp Fantom with only 2 cyclones has a clean white HEPA filter with equal use for such a long time? I think the increasing use of more cyclones without increasing airflow is actually hampering performance of the design. If filters restrict the airflow the design doesn't work as well. I'm half tempted to remove pre motor filters from one for experimental purposes. Anyone else notice this?
