Manufacturing problem 2

I do not put a star even if I find quite effective vacuuming. The concern is that the room for holding the brush and vacuum hose is not strong enough and break after a few uses. I had already pointed out, Amazon was immediately changed the product but the same thing happens again. I regret that a piece that should be robust given its use yields like that so easily and quickly. My old vacuum cleaner at least 15 years with the same process that never broke.
