Xiaomi Robot Vac Gen 1 Issues with Drive

My Gen1 Mi Robot Vac started behaving strangely lately.
Main problem is that it is now getting stuck on rug edges, pens etc etc - way more often than it ever did. Before, it was something out of the ordinary not to find it at the dock after cleaning. Nowadays its almost every time I have to go search for it.
Do not know if its one of the later firmware updates (don't want to do a hardware reset to find out) or just drive motors are getting tired or something else.
Feels that the wheel mechanism just does not have enough power to go over obstacles. Or, maybe it is now somehow tied with the fan control - if chosen a quiet fan setting, maybe it is sending less power to the wheels too?

Anyone had experience with something like this? I will probably retire it next week, just dont want to get rid of a thing that works great otherwise

    May as well reset it to rule out software, if you were going to decommission it anyway…

    • not for another 6-12 months =) I run Valetudo on it for Home Assistant automation. But it started well before I started playing with it

      • Try a new battery too, maybe the original one is not up to snuff? I used to find mine randomly all over the place, I think it wanted to get home but it "Cannae Do It Cap'n, It Doesn't Have the Power" :)

        • yeah, battery is not at its prime - cannot finish the house clean on one go on balanced fan setting.
          But should still be ok in the beginning/just off the charge state.
          Its works fine most of the time, but when it gets near the rug edges, problems happen

  • when was the last time you replaced the brushes and gave it a proper clean?

    I did a full clean and noticed the sound improvement straight away

    • Main brush not for some time (8-9 month I think). Side brush maybe 6 months ago. But I dont use it every day. Now that its on auto pilot through home automation, will be used more.
      Its not so much the brushes, but feel like it cannot climb over obstacles as well as it did before

  • Did you have any luck with this?
    We have the original Mi Robot Gen 1 and have been pretty happy with it, but lately find it gets stuck trying to climb onto rugs. It used to happen ocassionally, but it seems to be a lot more frequent now. Firmware is 3.5.8_004028
    I'm not sure if the newer models with 20mm climbing as opposed to ours being 15mm would be less problematic.

  • Seems to be the firmware 3.5.8_004028

    Mine lost English voice 🤬

  • gave up and sold mine. Have Viomi s9 from one of the recent deals. I like it but has its own quirks
