Wish there was a zero star option! I received the M7 Pro last week and have had nothing but problems since opening the box. First, there is very little information in the manuals that come with the device and the dust collector. Second, the M7 app doesn't work with Android phones. Third, the device runs out of power before I finish my house. Fourth and biggest complaint, the device doesn't get thrown in the trash. I have only run the device 3 times, each time the device is docked and emptied and the dust box shows a message saying the bag is full and needs to be replaced. The bag is empty and the device will NOT be emptied into the dust bin. I tried to "chat" with tech support on Proscenic website but it was useless. Then I wrote to the support, no answer. It was a waste of money! I will go to Costco to buy IRobot which is the first thing I should have done.
