I tried placing it in a tiny corner (around 0.5 m width) between my desk and wall, it still works well but took longer time navigating to home. Obstacle evading performance: excellent! My home has couple of sliding doors with wide base. The vacuum robot did very well in cleaning those base and corners without stuck any time.
