However, on large expanses, the robot is superb, albeit slow. It struggles if it does not have much space to maneuver. In use, the robot prefers larger window panes.
#Hobot window cleaning robot reviews windows
If your windows are really dusty or dirty, then I would recommend doing the dry cleaning several times before using the wet clean to make sure that there are no streaks or smears. It takes about 2 minutes, 24 seconds to clean a square meter of glass. The 298 follows a structured zig-zag path across the window spraying ahead of it as it goes. Hobot says that the robot will clean up to one square meter using one milliliter of water. The wet clean uses the ultrasonic spray to intermittently spray a tiny amount of fluid onto the glass ahead of the robot. Hobot recommends that you dry clean the windows first using the cloth, before using water, to prevent any smears as the water mixes with the dirt. Fix the safety cord carabineer to a safe place to ensure the robot will not be damaged if it falls.įill the water tank up with water, fix the cleaning cloth onto the cleaner, place the Hobot onto the window, and switch on the power. If the power is interrupted, the robot will stop and beep, and red and blue lights will flash. The battery is a UPS so that if the power fails, the robot will not immediately fall off the window, but will stay attached to the pane for up to 20 minutes. You do need to fully charge the battery on the robot before using it. There is also a power switch on the robot itself if you do not like using the remote control. The remote control lets you manually control the direction of the robot, or select the mode of direction. Plug the power adapter in with the extension, hold the robot against the window, and use the onboard switch to start the vacuum suction. The robot has a detachable water tank for water for the supplied window detergent.

There is also a spare electrostatic water nozzle. The power adaptor has a 4m long cord so you can clean the furthest reaches of the window pane. This is so that if the robot falls off the window, it does not fall onto the ground. The robot has a safety cord that you attach to a point on your window frame. Inside the box is the robot, three cleaning cloths, a bottle of window detergent, a remote control, and the power adapter. It sticks to your window by suction and will clean your windows using an ultra-fine mist - without any intervention from you. It is a compact cleaning device unit under 9 inches square and 4 inches high (240 x 240 x 100mm). The Hobot 298 is an impressive-looking window cleaning robot designed for small to medium offices that may not have the budget for regular window cleaning services.
