Robot unable to clean Kitchen

We bought L50 ultra CE in July. After just 2 months of use we are seeing that the robot is unable to clean the kitchen. If I bring the dirt in centre for it to vacuum, it pushes it in the corner and the dirt remains there forever. Additionally, it is leaving brown mop stains everywhere.
Maintenance wise, we clean the robot every 2 weeks. Kitchen is the first room it cleans when we start cleaning out house so we are sure it's not about unclean mop pad from another area.

I bought it yesterday its inferior compared to old L10s pro ultra. The navigation,mapping and dirt detection was much better i think in L50 the camera is not there thats causing improper image processing.

I expected when i buy higher version i get better features but here they increased suction and gave a extendable hand but poor mapping and dirt detection. Also it just wonder around carpet because it dont konow ita carpet while moppiny
