I got a iRobot roomba i7+ with self emptying base for cheap ($350), ive been using it for about 3 years now and its alright, but the mapping system sometimes creates 'hallways' that don't exist. I also got a iRobot roomba i1+ from goodwill for $10, which i keep in my basement. Its a bit stupider and you cannot tell it to vacuum a room twice but for $10 i cant complain.

If you have that much money you are willing to spend on a robot vacuum I recommend getting a Roborock
