First there was the Roomba, which is a clever little robot that wheels around rooms in your house and vacuums the carpets. It’s one of those “why didn’t I think of that?” concepts, and I don’t know how successful or popular the devices are, but I’ve always considered them pretty cool.

Add a new chapter to “why didn’t I think of that?” as the Auto Mower is released. Here’s a quick summary:

It works similarly to the Roomba robot vacuum in that it self-charges at a docking station, navigates on its own and can be set to run on schedule. You shallowly bury a boundary wire around the general perimeter of your lawn and any gardens to let the machine know its limits. It can handle inclines, rain and simply reverses itself when it bumps into things like trees.

The Auto Mower runs on a rechargeable nickel metal hydride battery that can mow for about four to six hours between charges. Since it’s quiet, you can set it to run at night. In fact, the company says it only needs to be set up once at the beginning of the season and then can be left on its own to mow and charge. Safety sensors stop the blades– which only spin while the machine is in motion– when the machine is lifted off the ground.

Sweet! I’d buy one if they cost less than $2,000– that’s a hefty sticker price.
