iRobot Scooba 6051 with Battery, For Parts or Fix Nothing Looks Bad Needs Charger! Honestly this looks like a brand new iRobot. I’m going to confuse you very much with the model. Yes the model number is 6051 witch is the warranty model for 6050 or 390 if you need any parts please buy iRobot 390 parts! I had to dig around for a long time to find anything about this model. I found out that this model is the warranty model to a 6050 witch in itself is also hard to find. Not sure why. So...mewhat I guess you could say it’s a rare model. I have not seen another 6051 before. It comes with a battery, it is a iRobot battery inside it. If you have a charger this should would no problem looks really clean. Please send me a message with any questions you have, thank you for looking at my listing!
