Input: After searching for weeks to find a vacuum that would do the job, I ended up with this one. This is my fourth canister vacuum. And by far, it does much better at getting pet hair and debris out of carpet than either other previous ones did. The big disadvantage is how loud it is. It's very noisy. The noise level can't be ignored. If there's some sort of "air vent" somewhere near it, it's probably doing nothing. Also, if you don't empty it, every little bit helps.
Output:
Good Review
