This is the robot vacuum cleaner "CLEAN Robot." It's a simple type of automatic vacuum cleaner with a design that only uses button operation. Since there is no manufacturer or model number listed, it is listed as **manufacturer unknown (no-brand product)**. The exterior is in relatively clean condition. It should work after pulling out the string in the back. Operation is unconfirmed. This is a new, unused item. It does not come with side brushes. No price reduction.
