I just cleaned the floor this morning but with the robotic vacuum for just ten minutes I checked the collection box, I can find loads of dust in it, it can even pick up a LEGO block and a small real brick (see photo). , light weight and low noise, will recommend to friends! It's really functional! My house has two floors, I plan to buy another one!
