I purchased the robotic vacuum cleaner for my small appartment where I stay during the week while working. This little machine is great! This cleaner costs half of the other brand in local stores. I just turn on and forget it. When I come back to the place all I do is dump the collecter into the trash and plug the vacuum back in to charge. I can use the remote control to clean the particular spots that it missed. Overall, I'm really satisfied with my purchase on Overstock.com. Shipping was lightening and almost free!
