With the soft brush to prima all smooth surfaces (eg. B. wooden staircase, wooden furniture, monitor / TV, glass surfaces, bath / shower tray, leather sofa, wallpapered walls or even Rauputzwände) can suck a large area, but also between crevices z. B. on sofa or leather armchair with the front part of the brush (second, separate intake) suck dirt. I do not want to give up the useful "helpers", with many a dusting with a separate cloth now omitted. Only with especially sensitive surfaces should be on the brush care not flat set up the whole area, because they can be fixed eye by the high suction force from time to time. Therefore, better keep a slight angle when vacuuming. But can damage or scratch to you with the brush no surface because the brushes inside the entire surface a velvety reference has.
