Roborock S8+/S8 vs Dreame L40 Ultra

The Dreame L40 Ultra is much more feature-rich than the Roborock S8+/S8, but the Roborock has the edge performance-wise. The L40 Ultra's base station can empty its dustbin, refill its water tank, and clean and dry its mopping pads with hot water and air. The obstacle avoidance system is also much more advanced than the S8, with an RGB camera, LED light, and a more advanced sensor. That said, the Roborock is more effective on every surface type and offers better mopping performance. These performance differences are mostly due to the L40 Ultra's haphazard pathing, which yields inconsistent results.
