Title: DRIVE WHEELS FREEZE, DON'T EXPECT CUST SVC
Review: I HAVE OWNED TWO UNITS AND DRIVE WHEELS HAVE FROZEN ON EACH. I SHIPPED THE SECOND UNIT TO IROBOT AND THE ITEM WAS THROWN IN THE TRASH SINCE MY RETURN WAS UNAUTHORIZED. THESE GUYS ALSO MAKE ROBOTS FOR THE U.S. MILITARY, LET'S HOPE THE SUPPORT IS BETTER FOR THEM!
