Works - barely. There were absolutely no instructions, although it's not difficult to find out, I'm just reporting. After watching a few videos I figured out how to disassemble the canister, put this pup in it without breaking anything, put it all back together and put it back in the vacuum frame - wouldn't snap. After several attempts I managed to keep the thing in place, but every time we use the vacuum I wonder if the canister will fall out. I haven't cleared it since I installed it, a little reluctantly, but there comes a day when I have to. I just hope I can get the canister to stay again. LAUGH OUT LOUD. OK, that's my review.
