Unnecessary. With a few simple steps on full suction with old filter

I was also angry. My Dirt Devil M5050-0 I had purchased for a mere 34 Euro set down a year ago, weakened from month to month more and more in the suction. Had the other sponge filter behind this is removed with moderate success. Today then grabbed the overheating protection of the sucker and he turned away. I thought to a total loss. Call the hotline and wait showed, however, that had only the overheat protection is activated and he ran afterwards. So, now I've even looked at exactly this filter more precisely. Have him try to clean under running water. The dirt dissolves well, but remains at the "gauze" hanging in front and which was stuck behind the filter itself. So gauze away and behold, the filter can be washed out easily and the suction draws really is as good as on the first day. Well folks, you save your money and cleans yourself the motor protection filter. The gauze itself has to keep in my opinion no practical use other than just the dirt in the filter. So pure moneymaking.
