I’ve done quite a few other teardowns as well: https://syonyk.blogspot.com/search/label/Teardowns
Mostly battery packs, but there’s some other stuff in there.

Great writeup! I don’t have anything to add on the technical side, but I think the cat is holding a collapsible telescope, rather than a lint roller. You can make out the eyepiece and the three-section body, and it even looks like there’s a crescent-shaped “reflection” molded into what would be the front lens.

That is certainly possible!

I wonder if that expansion port is for the i7+ where it can auto empty in to the bin.

Nice teardown. The golden circle in the brush roller compartment is a piezo electric debris sensor, it detects the impact of larger debris like pebbles, cereal, etc on the plastic of the compartment and is used by the system to detect areas where extra power/time needs to be used.

The floor sensor detect movement of the robot over the floor (XY velocity vector) to be used in VSLAM. It works like an optical mouse.

Anybody knows what piezo debris sensor is used in the roomba 671?

Hi I have a Irobot 7 whit dead left wheel, do you have the schematic circuit for casuality?

Hi. Mine stopped charging. Even with a new IRobot battery. Can I send it to you? How can you find people that fix them. I’ve never had problems till this i7 and I love the darn thing.

No, sorry. I don’t repair them. They’re consumer electronics, you buy a new one.

Just saw this teardown, excellent. I hate the lame YT ones where you have to watch someone fumble around for what seems like forever, then provide no real info. Now we need a software teardown. Of course,very not trivial. But from what I’ve found, the software is as cool as the hardware. It makes heavy use of AWS cloud services,Kinetics and Lambda being the more interesting. Oh, right, I’m an EE and CS guy, love hardware and software. Keep up the good work!

Oh, forgot. Back to your battery pack terminal comments, many include terminals for a thermistor to monitor temperature for controlling charge rate. I’d expect the same for this one, required for fast-charge.
