Looks nice, great idea and design, but there are problems. The vacuum software has serious problems and will frustrate you. Vacuum can very rarely do all the work. If a little thing happens like you pick it up or it gets stuck, forget it, you have to start your work over. The lidar gets stuck climbing up and down while trying to dock, forcing the job to start over. For the price it's SUPER. I promise you will be disappointed. I've tried MANY vacuum robots and the Roborock s7 still wins.
