We originally owned a Eufy 30c which was a ‚dumb’ version so no map drawing, LiDAR etc. Watching it run completely clueless and bumping onto furniture and walls was a pain but must admit it was doing its job and floors were always clean. It served us 6 years with only replacing a brush and filters. Still working this year so sold it on.
We now have Lubluelu which are a fraction of the cost of iRobots and they are great. The first one is going strong since April 2024.
