The original model of this vacuum cleaner belonged to him before anyone else. It performed well and without any issues or errors. This is why I bought the new Mop 2 Pro vacuum and why I hate it so much. The vacuum's buggy software is a frequent source of annoyance; for example, increasing the number of passes is impossible when selecting zone cleaning. This function was present in the original, most basic model but is absent in the Pro. This is complete bullshit. These are minor annoyances compared to the times he smacks the wall because he can't get his bearings when cleaning. Requests to locate the docking station provide no results. The map is oddly mirrored, and a game is drawn on top of it. You'll need to power it down, transport it back to its charging dock, and begin the cleaning process all over again. What do these Lidar types who like to put on a show want to know, anyway? In sum, I was underwhelmed by the vacuum cleaner, and the software clearly had to be developed by a bunch of scumbags. If anything, the firmware is up to date.
