Bests & Worsts Reviews from Amazon

Was on the verge of returning this. First impression was the utterly novice garbage app with Chinese characters everywhere. I'm guessing roborock paid bottom dollar for software 'talent' and passed the savings on? Can't integrate with Alexa because the app is gibberish. Zero stars on that count. Next, I try it out, and this thing is LOUD. This would be my third robot vac and it is by far the loudest ever. The motor is loud and it makes awful screeching noises on the hardwood floor as it turns. After this double whammy, I prepared to return this back to the Chinese garbage factory whence it came. Decided to try it out a couple more times first and noticed that this unit doesn't get stuck like the others I've had. As long as I'm not around to hear the awful noises it makes, it actually cleans quite well and reliably. I use the button to start it; the app is complete garbage made by Chinese zero-talents with no knowledge of user experience and localization. But as long as I don't have to look at that abomination of an app, the vacuum works surprisingly well. And so I've decided to keep it. I can go out on an errand, start it up (using the button, not the crap app), and return each time to it neatly parked, dustbin lightly occupied because it got most of the dirt last time it ran. To add, this unit has the most graceful way of navigating obstacles that would have certainly stopped my other units in their tracks. It seems to be quite adept at untangling itself from a stray cord I forgot to put away, or finding its way out of a tight space. Maybe roborock should use it to clean out their garbage app team next...
