WindEveryone can enjoy the view through the spotless windows in ease!

HOBOT-298 brings revolutionary bio-mimicry technology into play. The new invention carries a detachable water tank along with an ultrasonic water spray nozzle which nebulizes water to 15um mists then sprays it evenly on the glass like the effect of human exhales on a glass surface. The volume of the water tank is 40ml, which enables HOBOT-298 to clean a 40m2 area with water or detergent.

No more spraying in advance, HOBOT-298 will take care of everything for you now!

Inherited the sleek square exterior from HOBOT-268 and 288, HOBOT-298 carries Nidec brushless motor with metal fan for extended durability and lower noise. Window cleaning has become the easiest thing ever.

Power Cleaning

A powerful vacuum makes HOBOT robots stand on the surface of the glass; meanwhile, it sucks out the dust and removes the impurities.

High reliability design

An auto-adjustable pneumatic pad automatically controls the driving force and keeps the force between caterpillar treads and cleaning cloth in proportion, so extremely dirty glass surface does not interrupt HOBOT robots' task of cleaning the whole window and make it slippery.

AI Smart Route Plan for Thorough Cleaning

Auto edge detection with AI smart route plan – Zigzag path in both horizontal and vertical directions in a cleaning cycle.

Efficient Movements

Two caterpillar treads are attached to HOBOT robots which are quick to move at 12cm per second. To be precise, HOBOT robots clean one square meter in 2.4 minutes.

Large cleaning area

A piece of micro-fiber cleaning cloth with 24x24 cm is attached on HOBOT robots. The large cleaning cloth is highly suitable for homes, offices, cafés, restaurants and other kinds of small-scale businesses.

Laser sensor

The laser sensor is used for measuring distance and height, which enable measure precise distance while HOBOT robots freely work on frameless windows.

Long Power Cord and Embedded UPS System

The power cord is as long as 4 meters that allows HOBOT to work on a large area or even when the power outlet is far from the window. Embedded UPS keeps HOBOT staying in position with alerting sound for 20 minutes.

Bluetooth APP Remote Control

Stay in control with your smartphone, HOBOT App not only works just like the remote control, but also send notifications such as alert or when cleaning task is completed.
