I have both an aquabug and a zodiac wahoo. The Wahoo does a good job, but it is fussy to get working. You have to get the suction set up right, or else it either lies there dead, or climbs out of the pool. Once you figure out what setting to run it at, it works fine, it patterns well and seems to not get stuck at all. It does a good job with fine material, but sometimes it ends up just shoving large leaves around, as opposed to sucking them up. If I want my pool really clean, I vacuum it myself.
