Beatbot's smart skimmer comes with a sky-high price tag, but aside from its competently designed app, it doesn't outperform one of its simpler and much less-expensive competitors. While testing the Beatbot iSkim Ultra, it occurred to me that a pool-skimming robot probably just isn't a very good idea. I'm not saying that the Beatbot iSkim Ultra is a bad product per se, just that, for most pool owners, robotic skimmers probably aren't a worthwhile investment. If you have a pool pump with a thru-wall skimmer, you almost certainly don't need a robot for the job--unless perhaps you live in such an extremely tree-laden environment that the wall skimmer can't keep up. Even then, I can't see how you would ever be fully satisfied with your investment in a pool skimmer which, to be frank, isn't cheap. A'rocket' button lets you double the Beatbot iSkim Ultra's speed, which is about as much fun as you can have around the pool without getting in.
