I'm selling this item as I haven't used it in a while, after using it for about two years. *This product requires a battery replacement.* Due to an error display (red light when charging, 5 beeps), the battery needs to be replaced. Replacement batteries are not included. Separate purchase required. It was working fine before the battery error occurred. There is no instruction manual. Quoted from the product HP below: Easy Automatic Cleaning The Eufy RoboVac 11S is a robot that automatically cleans your room. You can select various cleaning modes to suit your room, and you can also set the cleaning schedule. It allows for hands-free cleaning. A Cleaning Experience Like Never Before By reviewing the design in detail, we have achieved cleaning with a quietness similar to that of a typical microwave oven. Also, the Eufy RoboVac 11S, which is about 7.2cm high, cleans in places that are difficult to reach, such as under furniture, in your place. Slim but Powerful Despite its ultra-thin design, the Eufy RoboVac 11S, equipped with BoostIQ technology and delivering a maximum suction power of 1300Pa, can suck up all kinds of dirt and dust attached to floors and carpets. Even Where Your Hands Can't Reach Equipped with a 0.6L large-capacity dust container, and by making the most of the 100 minutes (*1) of continuous operation, it can suck up dust and dirt throughout the room. Premium Design The top surface is made of scratch-resistant tempered glass cover. The beautiful appearance and high strength of the Eufy RoboVac 11S body are both achieved. In addition, a 3-layer high-performance filter is used for cleaner cleaning.
