just another example of how the Chinese tech is overtaking US. Roomba invented robot vacuum and owned almost 100% market share for years, now it's a foot note near bankruptcy with vacuums that are years outdated.
I wasted thousands of dollars on 3 different Roomba over the years, they all sucked (no pun intended) and required more maintenance than they are worth, getting stuck, not able to auto dock etc... Then I tried a Roborock and it was everything I imagined what a robo vacuum should be - lidar navigation, anti hair tangle brush with no maintenance, auto empty, 100% perfect auto dock every time, and an amazing app that shows you exactly what the robot vacuum did...that was about 5 years ago and I never looked at a Roomba again.
Fast forward to a year ago when I finally upgraded to the wet mop version, and it was another eureka moment, the thing just works perfectly. One of the headache that make wet mopping not worth it is you have to clean the mops afterwards, but with this one it auto clean and auto dries, so the only thing I needed to do is empty the dirty water, give it a quick rinse, and fill the clean water bucket. It mopped floor like a pro.
I am constantly amazed at the amount of tech that got packed into this thing and how well it works.
PS my old vacuum only Roborock is still going strong at my mom's place, she still calls me quite often and tell me how amazing that thing is (~5 year old tech).
