I love my Roomba. So it is nice to see NASA working on new uses for them.

After facing a number of dissapointments over failed Mars missions, NASA has decided to use an already proven technology for the exploration and collection of soil samples on the surface of the planet. "We've ordered 1,000 Roomba robotic floor vacuums from the Sharper Image," said Johnson. In a move of what could be considered fiscal genius, NASA also opted for the five year extended warranty. "How can we lose? If the project is a failure, we just make them replace the non-working units and we can sell them on eBay. Have you seen how much money people will pay for crap with an official NASA sticker on it?" [Trial and Error]
