Thank you for viewing. I purchased this along with a Roomba, but my dog is scared of robot vacuums, so I've decided to sell all of them. I have used a Roomba, and this item is New and unused. Brand: NARWAL Model Name: Freo Z Ultra Color: Galaxy Silver Product Dimensions: 35 cm length x 35 cm width x 10.9 cm height The Freo Z Ultra is a high-performance robot vacuum cleaner equipped with the latest dual cameras and dual CPUs. This robot vacuum cleaner is equipped with a SoC that handles 3D games, enabling up to 4 trillion calculations per second, and performs AI functions such as spatial recognition, depth calculation, and object recognition overwhelmingly smoothly. This allows for concentrated cleaning without spreading dirt to other areas. No smokers in the family. Pets are present. Thank you.
