Just picked up the package, opened and two grown people have then 5 minutes unsuccessfully tried aufzustecken the brush on the Siemens vacuum cleaner (model Q5). A search on the Siemens website revealed then that the acquired brush looks different than the part shown at Siemens (other colors, lack of signature "Turbo"). Obviously it is not an original part. Since it can not attach to the vacuum cleaner, unfortunately completely useless - is declining. Very dissatisfied !!!
