I can compare because I have three different brands of robot vacuum cleaners. This vacuum cleaner behaved in a very poor manner. What precisely was disliked: 1. The application is very "raw," with some features completely inactive. For instance, it is not possible to create a 3D map or divide an apartment into rooms. 2. The vacuum cleaner can ride wherever he wants. It has the ability to leave a location and arrive to an empty location right away. frequently stops moving for three seconds before breaking off in a completely new path. I've never seen such a peculiar movement algorithm before. 3. Despite having a fairly high price and the stated features, it collects twice as little trash as other vacuum cleaners. I bought it since it had great advertising, but I wouldn't suggest anyone purchase this item.
