Winbot WA3 is an intelligent wireless robot for cleaning windows. With a 3,000 mA battery, it runs for 50 minutes and cleans a total area of about 16 sqm. It has a programme for thorough cleaning, the N- and Z-shaped cleaning process, which automatically increases the cleaning effect. When the battery is low, the robot automatically returns to the charging station. A vacuum real-time detection feature increases safety and sends a reminder when there is not enough intake air.
