I got the Roborock Q Revo a little under a year ago, as an upgrade to a Neato Botvac 80 that had just broken down. Robot vacuums have come so far in ~8 years they're very nearly an entirely different product.

I think OP's issue with Roomba is simply that it was a Roomba (depending on when they tried it); I did a lot of searching before deciding on the Q Revo, and it seems like iRobot had been relying on the Roomba brand name for some time and until very recently was still playing catch-up. Not sure they have caught up when it comes to navigation and the control app.

Also a happy Q Revo Pro customer. No mic/camera, but with the lidar the auto location and pathing is shockingly efficient. And vacuuming might be easy, but mopping is a pain that I never have to deal with anymore. The difference between a pure vacuum and a vacuum plus mop on hardwood floors is night and day, especially with two pets.

After initial setup the Q Revo does not need internet connectivity. So you can set it up using an ephemeral hotspot and afterwards control it exclusively with the buttons on the top of the unit. Any errors are spoken by the device.
