There is a black plastic flexible ring that runs on the bottom of the top part of the canister with the perforated metal surface. The hair as you can see in the first picture, is going by that black rubber piece. Then it works its way around to the air intake, which is in the metal perforated structure. So anything that gets around that rubber ring makes it to the intake. It seems that the rubber piece cannot completely seal, otherwise the vacuum doesn’t seem like it would work. But maybe it’s supposed to be very close so only dust gets through and not large particles.
The square air intake shown in the front of the second picture is getting clogged up with pet hair that is getting past the rubber gasket in the second picture. It fills up each time I use the vacuum, causing an error that the air intake is blocked, and then I need to clean it out with a toothpick.
Any ideas?
