the hoover things are gravel cleaners, I use one when I do my water changes as I think, do most people here. You can also get battery/air pump powered ones, that will clean the gravel in between water changes without removing water. I have one, and it works OK, but i rarely use it as I find that the tanks don't get dirty enough to use it in between water changes!!
I don't know what the other thing you mentioned is, but I'm always dubious of things that claim to miraculously remove ammonia/nitrite. they rarely work, and cost you unecessary money!!!
