I have 08 allergy bought the brush to my Dyson DC to. To staubzuwischen with the brush, you have to get used a bit, since the thickness of the vacuum cleaner hose interfere partially. Of the dusting performance of the brush I'm thrilled. If I "wipe" only narrow areas, I think the rear suction hole of the brush to the finger. A real alternative to dusting. Especially no dust is whirled and the dirt is really gone.
So far I have not had problems with the adapter piece that connects in the brush with the sucker. The already mentioned problems I can not understand.
