Question about Mammotion Luba mini AWD 1500

If you are referring to the cutting edge, the Luba Mini leaves a wider strip unmown than its big brother, the Luba 2. This is not a problem in open areas, as the Lubas can simply mow overlapping. However, if the mower drives along a wall where an overlap is not possible, a strip of mown lawn will remain (due to the distance between the edge of the cutting disc and the edge of the robot lawnmower). With the Luba 2, this is less due to the design.
There is an interesting review about this on YouTube: https://www.youtube.com/watch

The robot lawnmower does not offer a specific function for "automatic edgeless cutting" in the conventional sense, but it can perform precise edging automatically. This means that it cuts the edges of your lawn cleanly without you having to activate a special edging mode.
