Protects the floor but not the back!

By cons, this brush is completely obsolete compared to what is done by brush:

- No flexibility !! as long as you do not penchiez as the right angle, the brush off the ground. Unable to suck in the corners, under furniture, etc. In short we really loses suction efficiency and height of the brush, sometimes in bad wielding a hard plastic corner could still scratch the floor.

- Aspiration average low! One central suction flow path, a very dense brush curtain at the front and at the rear. Dust can hardly be sucked by the sides.

= Disappointed overall. Any base brush included with the vacuum cleaner has resolved these problems long ago. 20 years we go back with this brush, but hey the floor is not scratched ...
