About 1 week before I ordered the DC29 with soft brush. Just awesome !!! Unfortunately I only later the mattress brush entdeckt.Da she had so many good reviews, I just had it me now! Today I tried it. And I am appalled !!!!! Ugh, it we slept ?????? After a short time, the finest white dust collects in the container. I always thought we had a pretty well-kept household. Are you kidding me? Are you serious when you say that !!! The mattresses live ... The brush fits the way definitely Dysonsauger. Although not all models are listed here on Amazon .There are included so that's something for every sucker this adapter. I highly recommend this brush just very urgent !!! This one really is at night alone on his mattress ......
