Has your cabana boy, Sergio, been shirking his aquatic responsibilities, sipping Mai Tais and tanning instead of skimming leaves? Well, pool possessors, it may be time to fire the laggard and replace him with the new Polaris 9300xi Sport. This newest Polaris poolbot can be programmed to perform its janitorial duties for up to six hours at a time of your choosing, and has a remote control for spot-specific scrubbing. Not only that, it combines water-jet propulsion with wheels that can climb walls and steps to spruce up every nook and cranny of your backyard basin in true Spiderman-style. Of course, such underwater robotic wizardry doesn't come cheap, as the 9300xi has an MSRP of $1499. That makes the iRobot Verro 500
and its $999 price look like a robot bargain by comparison, but it's still cheaper than Sergio, right?
