With circles, corners cannot be cleaned. That's why Neato introduced the D-shape over 15 years ago. The D-shape allows the vacuum cleaner to have a brush directly at the edge, instead of between the wheels like round robots. This design also accommodates an extra-large dirt bin, allowing for less frequent emptying. The result? Deep cleaning in no time, from corner to corner and edge to edge. With 200 minutes of runtime, it has an 85% longer battery life than the D6, making it perfect for medium to large homes and apartments. While it covers a large area, if your robot runs low on energy, it will pause cleaning to recharge briefly and then finish the job. With its suction power and ultra-efficient HEPA filter, it captures up to 99.5% of allergens and dust particles. Neato gets the job done, whether in energy-saving Eco mode or powerful Turbo mode.
