My iRobot Roomba 4150 started to exhibit a behavior that I hadn't seen before. After starting up, the robot would "wiggle" as it went forward for a few feet, then turn, then move forward a few more feet while wiggling. After a few turns, it would stop and issue a double "uh-oh" sound. After cleaning and removing the vacuum brushes, the behavior was still hapening, so I decided it must be a problem with the sensors or motors on the robot. The robot's wheels would still turn manually, and they would pop up and down into the body as normal. I tried cleaning the clif sensors and that didn't fix the problem. Finally, I blew compressed air into the drive wheel compartment and that fixed the problem. Aparently, the rotary encoders on one of the wheels had gotten jamed up with dirt. <\/p>\n
The iRobot website did mention an OSMO update <\/a> that is supposed to fix this issue, but according to the serial number on my roomba, it had already received the update. I guess removing the debris from the wheel is the better solution.<\/p>\n","protected":false},"excerpt":{"rendered":" My iRobot Roomba 4150 started to exhibit a behavior that I hadn't seen before.
