The company is reporting major financial problems and an uncertain future. How did things get this bad for the former robot vacuum leader? And will your Roombas continue to function?

As of March 14, you can get the iRobot Roomba (Q0120) for just $129.99, down from $249.99, at Amazon. That's a 48% discount and $120 off the list price.

Robot, the creator of the Roomba and the company that popularized robot vacuums in the first place, told investors on Wednesday that it has "substantial doubt about [its] ability to continue." Beyond declining sales — the company reported that revenue decreased 47 percent in the US over the prior year in its fourth quarter earnings — iRobot is also struggling to pay off its debts.
