Piper Jaffray analyst Troy Jensen upgraded iRobot to Overweight from Neutral and increased his price target to $78 from $63. Jensen said that tracking data shows iRobot is experiencing "exceptionally strong demand in North America," and he believes the demand is likely share gains for the new Shark and Neato products as well as better than expected demand for Roomba vacuums for the March quarter. Jensen also believes new product introductions in the second half of the year and increased marketing spending in Europe and for the BraavaJet will provide additional tailwinds for iRobot.
