I have DC19 Allergy (taken as 20220). During the use of about 3-4 months, there is only one drawback: the transparent flask does not fit tightly to the cyclone in the suction area. Although the dust does not fly out of there (probably because of suction). Just check before buying! On the cyclone itself, dust (very very fine like flour) accumulates decently, but the flushing will be completely eliminated (although the instructions do not recommend doing this) Apparently because of the danger of moisture getting into the engine. Dry thoroughly and no problem.
