Roomba i9. Its predecessor (can't remember the model) lasted for 12 years and its random cleaning algorithm was great. I only bought the i9 because the old ones battery stopped charging and there were no more replacements. It was not smart and worked perfectly via infrared remote. The i9 tho, let me tell you: you can't place it farther than 2m from the router because otherwise it loses WiFi permanently. 2nd battery within 5 years. IRobot demands an account login for every use of the app. I ask you, why would I login to an app? This is a robot, I press button and machine goes brrr - anything more and I get irritated. When it's done, it beeps. Sometimes directly after, sometimes 2 hours after, sometimes in the middle of the night. The cleaning is nowhere near as complete as the old, random algorithm. I will never buy IRobot again.
