We've seen iRobot (NASDAQ:IRBT) make the grade in Home Ec, but has it got what it takes to pass woodshop? Yesterday, the consumer and military robotics specialist rolled out the iRobot Dirt Dog.

Essentially, we're talking about a $130 robotic vacuum cleaner. It's similar to the popular iRobot Roomba, only it's equipped with a larger bagless debris bin to pick up small nails, sawdust, and other pieces of debris that tend to build up in workshops and garages.

Hitting stores with ample time for the holiday shopping season, this is just the kind of gift that one can picture selling briskly at some of the company's retail partners like Sears (NASDAQ:SHLD), Lowe's (NYSE:LOW), and IAC/InterActive's (NASDAQ:IACI) Home Shopping Network.

The company has moved more than 2 million Roomba automated suckers. It also rolled out its Scooba floor-scrubbing robot this past winter.

Perpetually expanding its offerings is essential, as iRobot attracts imitators in a hurry. As a Motley Fool Rule Breakers newsletter recommendation, it's been a disappointing performer since going public last year. A cynic would argue that even though the company will begin selling its Dirt Dog tomorrow, it's been a bit of a dog on the trading floor, too. Unfortunately, that's one floor that the machine can't clean up.

The stock's languished trading provides a sharp contrast to the dynamic company that continues to grow sales on the consumer front as it wins military contracts for its lifesaving PackBot bomb-sniffing robots. That promise and potential is why the stock remains an active pick in the growth stock newsletter service. Patience is what investors need as iRobot recharges its battery.

Every Dirt Dog has its day.
