By far the most disappointing for me has been the Roomba x2. I love the concept and when the first one didn't live up to the hype I somehow convinced myself the newer version surely had the bugs worked out. Neither lasted working in my house for longer than a few weeks. Not because they were broken but I spent more time dealing with them than I did just vacuuming. Haven't tried another robot cleaning device since.

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.

Roomba as well. Awesome at first when we bought our first home.

But then we filled it with stuff and got a doggo. Those hairs fast-track the process of jamming the wheels and sweeper. Why do we need a robot vacuum when we still have to vacuum by hand?
