With the patented dual ultrasonic spray nozzles, the Edge-Leakage Sensors, and the Creative Voice function, the HOBOT-2S will redefine your window cleaning experience because it couldn’t be easier! Our ultrasonic spray nozzles nebulize water into fine mist particles, employing biomimicry design concepts to imitate the human action of blowing a breath onto the glass before cleaning it. The innovative Edge-Leakage Sensors offer more accurate detection, allowing the robot to move effortlessly on any vertical surface. With the HOBOT App, you can now replace the default voice prompt with any sound of your choice, creating more fun and a personal touch to your robot. You can also update the firmware easily through the App to stay up-to-date with the latest features.

No more spraying in advance, HOBOT-2S will take care of everything for you now!

Everyone can enjoy the view through the spotless windows with ease!

Biomimicry Technology Dual Ultrasonic Spray

The ultrasonic spray nozzles can nebulize water into 15μm fine mist particles to deliver unparallel, cleaning results without leaving water stains, and clean 1m2 only with 1.4ml water consumption.

Strong Suction & Ascending Power

While the strong suction power positions HOBOT firmly on vertical surfaces and removes dust and dirt effectively, the 7 kg ascending power allows HOBOT to move steadily up and down without skidding.

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.

Multi-surface Cleaning

With the high volume centrifugal pump that consistently supplies negative pressure, HOBOT is capable of overcoming small air leakages and working smoothly on various surfaces.

Edge-Leakage Sensor

The Edge-Leakage Sensor technology can detect air leakage caused by the slight lift around the window seal or the edge of the frameless windows.

Cleaning Deep into Corners

HOBOT-2S introduces extended cleaning cloth deep into corners.

Large Coverage Area

The size of the microfiber cleaning cloth is 24×24 cm; the large size makes HOBOT suitable for homes, offices, cafes, restaurants, and others small businesses.

Efficient Routes

The two caterpillar belts attached to HOBOT moves quickly at 12cm per second; in other words, HOBOT can clean 1 square meter area in 2.4 minutes.

Intelligent Route Planning for Thorough Cleaning

HOBOT has auto edge detection and is also preprogrammed to work in zigzag routes first horizontally then vertically, cleaning thoroughly without missing a spot.

Long Power Cord

The power cord is 5 meters long, allowing HOBOT to work on large areas and surfaces far away from power socket.

Extra Secure DC Power Connector

HOBOT will stay wired through the extra secured DC power connecter to secure you a carefree experience.

Embedded UPS System

In case of power outage, the embedded Uninterruptible Power System (UPS) keeps HOBOT in position for 20 minutes with audio alert.
