bought one as recommended as we've got pets and 3 long-ish haired girls in the house.. i was getting sick to death of having to take the scissors to the brush roll every time i vacuumed to get the hair off.
This thing, that is SUPPOSED to prevent it, is exactly the same as the last one... doesn't prevent it at all,, still having to cut it free every time.
anti hair wrap my arse.
