Why is home sweeping robot technology not suitable for solar cleaning

Advanced household sweeping machines use visual slam technology with cameras as eyes, but why can't this technology be used to clean solar? because the visual slam needs a large number of distinct characteristic values to achieve positioning mapping, and each solar panel is identical, which cannot achieve high-quality mapping. Without high-quality maps, equipment safety and cleaning quality cannot be guaranteed. Household sweepers can also use laser slam technology to achieve positioning mapping. Because the solar array has no reflective surface, laser slam technology cannot be used so Kwunphi's use of semantic vision to solve solar cleaning is the world's first.
