Roomba’s software is continuously being updated and implemented in newest Roombas. When a
Roomba is serviced it is best practice to update the Roomba with the latest software code.

OSMO
Roomba’s have been manufactured with two different chips (E128 and DG256), and so there are
two software release to match the different chips. The OSMO Teal is used for E128 chips and the
OSMO Purple is used for DG256 chip. Determine the Roomba chip type from Roomba’s serial
number and then use the proper OSMO. Using the wrong OSMO does not harm the Roomba, it
just does not download software. Also, OSMO can only replace older software on the Roomba.
OSMO TEAL (E128)
- Roomba’s with barcodes.
-Roomba’s with serial
number with letter E or EA
OSMO PURPLE (DG256)
- Roomba’s with serial
