One caveat, there are unfortunately once again in the "Premium" vacuum cleaner models, accompanied by an electric brush, so when set into the telescopic tube cables. These are currently in particular the models 'Premium 8000' and 'S8930 HEPA'.
The brush fits thanks adapter even to this sucker ... however, the hose can not be separated from the hand-held unit, so that the whole construct is very bulky there. Luckily, the 'sub20' still enough adjustment to achieve the most complicated corners.
Significantly more comfortable it gets the 'S 8730' and the various smaller models: there fits the brush directly on the suction hose. Along with the extension hose 'SFS 10' to get in even the most hidden corner.
And because it is criticized repeatedly wrongly here, a word at the right application:
the thing is NO Polstberbürste, no hard floor brush and not a substitute for a scrubbing brush! The correct use is: light brush over - then the joints do not twist.
Etc. For automotive upholstery, mattresses, sofas. there are the essays 'SMD 10', 'SPD 10', 'STB 101' or 'STB 20'.
