iRobot may own the market for autonomous indoor cleaning devices, but when it comes to taming that wild jungle you call a backyard, the new king of the hill may well be the LawnBott LB3500. This fourth-generation LawnBott from Kyodo America improves upon its predecessors in nearly every category: even though it weighs ten pounds less than the entry-level LB2000, it offers up a greater coverage area, increased cutting width, greatly improved incline climbing capability, longer runtime, and best of all, a Bluetooth radio for programming or direct control by cellphone. Of course, all these high-end features don't come cheap, and when the LB3500 does come to market (date: unknown), we imagine that it's gonna cost a good deal more than the current high-end, $2,500 LB3200. Check out the gallery below for some more angles.
Update: Wow! Reader John Locke somehow managed to send an email from the island notifying us that The Robot Store has the LB3500 listed at $3,699, on sale for "only" $3,249. Also available is the "Super" LB3500, which is really just a kit that includes two extra lithium-ion batteries and tacks almost $600 on to the price. Thanks, John, but we bet Jack and Kate won't be too happy when they find out you have Gmail access.
