Yeah if your vacuum does enough for you with its Internet access restricted, then there’s probably no good reason to install valetudo. I chose to install it on mine because 1. paranoia, 2. I don’t have a good firewall solution set up yet, and 3. a lot of features on my vacuum are disabled if it can’t phone home, but valetudo re-enables those features.
I literally just installed this last weekend, so the docs are still pretty fresh in my mind. I still recommend you go read through that site to get the full picture and make your own informed decision, but here’s my tl:dr.
Valetudo, first and foremost, is intended to enable select models of vacuum robots to operate cloud-free. It’s not intended (nor is it feasible) to offer feature-parity with the manufacturers’ firmware/apps/cloud services. But in my limited experience, the only feature my robot is missing after installing valetudo is the ability to live-stream video from the onboard camera, which isn’t a big deal at all for me (and is something that the dev specifically won’t support). Everything else works flawlessly so far. It also allows you to configure just about anything the robot supports configurability for, like pathing algorithm adjustments, obstacle avoidance sensitivity adjustments, and a whole host of other things. I’m not sure if the manufacturer’s app even allows that level of configurability (because I never installed it), but I definitely feel like I have full control over my robot, and it functions flawlessly at performing its job of keeping my floors clean.
I think the biggest thing to be aware of is the rooting/installation process may require some soldering (not of the robot, just some through-hole soldering on a separate breakout board to make connecting to the robot’s debug port more foolproof), and requires comfortability in a Linux terminal. If those things aren’t in your wheelhouse, I’d say this project probably isn’t for you.
If you have a robot vacuum, and the robot vacuum makes a persistent map (as opposed to the older “dumber” models that just bounce around randomly), they all send that map back to some remote server. In fact, most of those robots won’t even enable the mapping feature unless they’re connected to the Internet (which is absolute bullshit considering most of those robots generate, process, and store that map locally, so there’s literally no reason to send it off somewhere).
So your options are to just use the robot without ever connecting it to the Internet and be happy with the reduced featureset, root the robot and install Valetudo on it, or just vacuum manually. But until manufacturers are forced to let us actually own the smart devices they sell is, under no circumstances should you ever let one touch the Internet.
That’s not true, there’s definitely ways to render the skin to the point where it’s all crisp, no slime, without burning it. It’s hard to do when oven roasting but possible, but it’s pretty easy to do when pan-searing.
