Has lots of suction, it's picking up but it doesn't go into the container, I took off the brush shield and took out fuzz but the black shutter is closed and will not open, how do I get it to open? I think when it's running it is staying closed the vacuum gets really hot on the hepa filter side and seem to be stuggling.
