Auto-ultrasonic spray

HOBOT-298 has AI Technology embedded that calculates paths and auto-detects window edges; you can clean your windows as easy as in one touch. HOBOT-298 also brings revolutionary bio-mimicry technology into play! The new patented invention carries a detachable water tank along with an ultrasonic spray nozzle which nebulizes water to mists then sprays it evenly on glass simulating the effect of human breath on the glass. HOBOT-298 is very water-conservation and eco-friendly, it can clean one square meter area with just one milliliter water or detergent. Additionally, the easily-replaceable microfiber cloth not only attracts dirt into fibers but also absorbs water to offer smear-free finish.

Bio-mimicry Technology
Ultrasonic Water Spray

Nebulizes water into 15 micrometer dense mist to dissolve the dust and polish the windows without leaving watermarks.

Power Cleaning

A powerful vacuum makes HOBOT stands on the surface of the glass while 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 balance.

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

HOBOT is carried by two caterpillar treads to move at 12cm per second speed – to be precise, HOBOT cleans one square meter in 2.4 minutes.

Large cleaning area

A 24×24 cm² micro-fiber cleaning cloth is attached on HOBOT to wipe off the dust. The large size cleaning cloth is highly suitable for homes, offices, cafés, restaurants and other kinds of small-scale businesses.

Laser Sensor

The laser sensor measures the distance between the glass and the device precisely while HOBOT robots freely work on frameless windows.

Safety Rope

The 4.5 meters long safety rope can take up to 150KG tension, please always tie the safety rope to the indoor fixture when using HOBOT.

Long Power Cord and Embedded UPS (Uninterrupted Power 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. The embedded UPS keeps HOBOT staying in position with alerting sound for 20 minutes in case there is a power outage.

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 alerts or when cleaning task is completed.

HOBOT Window Detergent

HOBOT Window Detergent is specially formulated to work with HOBOT-298 ultrasonic spray nozzle, pure water also works just fine too!

Replaceable Water Tank

In case the ultrasonic spraying nozzle is clogged, simply replace the entire water tank module or the ultrasonic spraying nozzle with just one screw driver, HOBOT will work as new again!

Nidec Brushless Motor and Metal Fan

High-efficiency brushless DC motor and metal fan bring long life expectancy, high durability and low noise.

Low Noise Design

(from 1 meter)
