Samsung POWERbot Essential Wi-Fi Robot Vacuum: Let this robot vacuum create a clean, healthy living space for you, with CycloneForce technology for consistent cleaning power. Scheduling presets let you set the most convenient cleaning times.
All thought the powerbot has good suction power, suction means nothing if it can't get to the dirt! The power bot is odd it will not go across air vents, can't get under furniture or clean along kick boards. So I purchased a roomba 880 which has no problem with the above mentioned.

I purchased a roomba 880 and had it 1 week when the side brush stopped working so I returned it and bought a samsung powerbot. The powerbot is probably good on carpet but did not clean near as good (showing me that suction power isn't everything). I returned the powerbot and gave the roomba another try. Glad I did I have had this one for over a month with no problems and like I said it cleans so much better than the samsung.
