My Roomba i2 is literally possessed by demons

My i2 is possessed by unholy forces.

It worked fine for the first 4-5 months but grew crazier and crazier with time.

Here is behavior it exhibits now:

• Cleans indefinitely in a single carpeted 700 square foot room despite being set to 1-pass (last two cleanings were over 6 hours before I canceling the job)

• NOT following a discernible pattern, returning to the same spots and bumping into things in a confused manner, zig-zagging all over the place, not cleaning in rows at all

• Pausing the job to recharge multiple times and return to its base, despite having >50% charge remaining, sometimes only after a minute or two of cleaning, other times after an hour

I did a second full disassembly and cleaning of my i2 for the second day in a row, including:

1. cleaning all of the sensors, drive housing, filter/brush replacement

2. factory reset including pulling the battery for a long time - reconnecting

3. deleting and reinstalling the app

I'm not sure what else to do. There should be an option on the i2 model to completely disable the "smart cleaning" and return to "drunken sailor" method with a time limit or returning when the battery is getting low.

I would flip that toggle in a second. The software is perplexing and bug ridden. When I reinstall the app, there's a second "clean everywhere" favorite that shouldn't exist. It gets progressively worse with time, not better - and it's clearly downloading phantom data from the last app from iRobot despite wiping the software. You would think a factory reset on the robot itself would fix software issues, but no. I'm wondering if its hardware related, but it is not throwing an error.

Do yourself a favor and stick to older model roombas that actually work. My 600 series is still running without issue after over 3 years of daily cleanings. I literally forget its there, minus emptying the bin/knocking out the filter daily, and cleaning dog hair out of the brushes once a month.

The i2 requires constant attention and must be canceled and sent home every day, or it will literally clean indefinitely!

Edit: update - after removing the battery for a long time (10 minutes or so), cleaning the drive housing, and removing furniture the indefinite cleaning behavior stopped. It cleaned the room in 47 minutes without issue like it used to ages ago.

There are so many changing variables it's tough to know for sure, but when the indefinite cleaning returns, I'll try one or the other to see what is causing the issue.
