      ...the Roomba is apparently really user-servicable??? The screws stay in the backplate, the motor modules are completely removable... I love this????pic.twitter.com/RKpvhSWl9F

      The motor module itself is far less user servicable dangit. I'm unsure if the issue is that there's cathair in the motor or the motor just went bad but either way there's way too much friction in the motor itself, I just don't see a good way to replace it without breaking this.pic.twitter.com/xdzwzub17R

      This is a 4 year old model too, I think? And they stock the replacement parts still and its that easily removable motor assembly? This is so not what I expected when I opened this up. TIL iRobot makes things modular and easy to replace.

      Not just replace, upgrade too! I replaced the dustbin assembly on mine with a newer design and the improvement is quite noticeable. Oh yeah and at least my model has a serial port hidden under the faceplate and they publish the protocol to control it, including manual driving.

          Spec for 500 series is here: https://www.irobot.lv/uploaded_files/File/iRobot_Roomba_500_Open_Interface_Spec.pdf … And they sell you the cable: http://store.irobot.com/default/parts-and-accessories/create-accessories/communication-cable-for-create-2/4466502.html … They also sell a version specifically meant for hacking: https://www.irobot.com/About-iRobot/STEM/Create-2.aspx … Also mine had this sticker on the package.pic.twitter.com/AAAxXPxAxQ

          Oh you have one of the serial ones, nice. I did not expect irobot to be such a decent company tbh? I'm so used to things being deliberately unserviceable and this is such a breath of fresh air

          Yeah, it's a rare sight. Honestly I'm very happy with mine, even when I had a nominally non-user-serviceable failure it was pretty easy to diagnose and fix (charging diode on the mobo was leaking reverse current, making it think it was charging itself and preventing normal use).
