I have own this vacuum for 6 week now and continue to be impress with how well it clean . we live in the high plain where there be alot of dust and have two dog who drop lot of dog hair . I purchase my vac with the standard sb217 power brush and also purchase the wider , sb228 power brush . the sb217 work well on med to low pile carpet and be the perfect width for do stair tread . for thicker carpet , opt for the 5 position height adjustment of Miele 's other power brush . my previous vacuum be a Dyson dc7 . this one be much quieter . in fact on the min set you hardly know it be on . we be able to vacuum the dog because the noise be low enough that it do not bother they . the agitator brush on the Miele do a great job loosen debris from the carpet fiber . I be still pick up dirt and sand that the Dyson leave behind . the parquet floor brush work great on the hard floor . it do such a good job pick up the grit , the floor feel like it be just mop . pro : Terrific cleaning on carpet and hard surface quiet adjustable power setting for various surface Bag & HEPA filter trap 99.7 % of everything down to .3 micron - no dusty vacuum odor Cons Power cord be shorter than I be use to Ergo handle be awkward when use the hand tool
