Very happy with the Dreame L40s Ultra robot vacuum. Great features, detachable mops, self-cleaning mops, and vacuum empties itself. The app is good too, lots of settings like vacuum first, then mop, so your carpets don't get wet. There is a learning curve with the app and setting up the map of the house, but once that is done, set up a schedule and let the robot do the cleaning. Our floors and carpet look great!
