This robot vacuum cleaner is made of cheap plastic that feels like something you'd get from the Dollar Store. It gets stuck very often or just goes in a small circle. It has nothing to "sweep" stuff to it and the compartment that holds what it does vacuum up is SO small that you have to empty it every few minutes. The cleaning path on this is about two inches wide and the suction is not very strong at all. Most of what is goes over is left on the floor. Do not waste your money on this.
