This item is a junk item! Roomba i3 Error c510: "Could not connect to Wi-Fi network" is displayed on the smartphone. I tried repeatedly, and tried to initialize it, but eventually, the power wouldn't turn on. I bought a new one and tried replacing the battery, but it didn't work, so I put the original battery back in. I'm looking for someone who is good with machines and can disassemble them. The dustbin has been washed and wiped where possible, but it is not perfectly clean. I will include a new filter. iRobot Product Name: Roomba Roomba Model Name: i3
