Both the S7 and the irobot vacuum cleaners have recently become exceedingly noisy due to their advanced age; yet, we do not wish to immediately replace either of them. The S7 seems more aesthetically beautiful, easy to communicate with, and silent in operation. Unlike the iRobot, it doesn't make a lot of noise while it's cleaning, and there are spoken messages that explain the vacuum's current state and where it plans to go next. Disadvantages include a somewhat smaller trash can compared to iRobot's, and my impression is that iRobot collects more trash from the same areas cleaned by S7 and by wet cleaning than S7 does on its own.
