iGarden Pool Cleaner K60 review: An underwater marathoner

This is a review of two pool robots, one which is the most exceptional cleaning device I've tested to date, and one that's maddeningly frustrating and overly complex. You've probably already figured out the twist: Yes, they are same device, the iGarden Pool Cleaner K60. To start things off, just look at the thing: With its jet-black chassis and orange-trimmed wheels, the machine looks more like a sports car than a glorified leaf sweeper. Despite the evocative look, it still moves about courtesy of large wheels and treads that abut a pair of spinning scrubber. Its biggest selling point is under the hood: A fairly beefy 7500mAh battery powers the 30-pound robot to an epic running time of up to 6 hours, according to iGarden.
