HOBOT-298 window cleaning robot is designed for cleaning hard vertical surfaces such as mirrors, glass, tile, window film, not to mention ordinary windows. Its removable water tank, gyroscope, and lasers are impressive features that make HOBOT-298 top of the market.
HOBOT-298 Ultrasonic is a window cleaning robot that features a separate water container and special nozzles that spray liquid onto the glass surface in front of the wipes. This solution is innovative and practically negates the manual wetting of wipes during robot cleaning on window openings (although pre-wetting is still necessary). This review will allow you to take a closer look at the HOBOT-298, find out its characteristics, functionality, and also pros and cons compared to competitors.
The US model is presented in white. If you look at the window cleaning robot from above, it is practically no different from the previous HOBOT 268 and HOBOT 288 models. The only thing that catches your eye is an additional fixed water container located on the side. This is the main feature of HOBOT 298.
The container is removable and can be removed and replaced with a new one if the ultrasonic nozzles become clogged and stop spraying water. The volume of the water container is 50 ml. The manufacturer indicates that the nozzles are very economical and consume 1 ml of water per 1 sq. So one fill of the water tank is enough for a glass façade of up to 250 square ft, which is impressive.
The bottom of the robot-wiper has a standard design: a cleaning cloth with dimensions of 9 * 9 inches is located over the entire area, tracks are installed on the sides for moving the robot, and an engine is located in the center (behind the ventilation holes).
The first thing to talk about is the navigation of the window cleaning robot HOBOT-298. The device is oriented in space due to the installed gyroscope, while the edges of the surface to be cleaned are determined by the installed laser sensor. It is important to note that this automatic wiper is capable of cleaning not only windows but also frameless vertical surfaces such as glass doors.
The robot moves along the surface with N and Z-shaped movements. The installed tracks allow achieving not only good traction with the surface but also a high travel speed - up to 5 inches per second.
The most important change is the installed water tank with special spray nozzles. Ultrasonic spraying allows you to achieve an economical, but at the same time, sufficient liquid consumption for cleaning glass. The detergent with water turns into a mist with a molecular size of no more than 15 microns. This is really impressive.
