Thank you for viewing. This is the ECOVACS DEEBOT OSMO Slim11 robot vacuum cleaner (Model Number: DK3G.11). ◇ Contents Robot vacuum cleaner body Mop Mop plate Remote control Charging dock Outer box ◇ Condition I performed a simple cleaning in preparation for the sale, but the main unit has scratches and dirt from use. When the vacuum cleaner body is placed on the charging dock, the power lamp on the main unit blinks and a beep sounds twice, but then the lamp turns off. Also, if you repeatedly press the power button the instant the power lamp comes on, the main unit starts to operate for a moment, but then it stops immediately. It seems that the battery does not charge even when left on the charging dock, so it is likely that the battery is completely discharged or the battery is defective. Please purchase only if you understand that this is a junk item. How about this opportunity? Thank you for your consideration.
