Product Description
HOBOT-268/288 is a square-shaped window-cleaning robot with a vacuum
motor inside that uses suction to stick to glass surfaces. The device also has two
caterpillar wheels that can freely traverse window surfaces, and even walls. The
easily-replaceable lint-free cloth is used on the pad. Micro-fiber cloth is used to attain
superior glass cleaning.
An embedded UPS (Uninterrupted Power System) can prevent the robot from
falling off the window even when the power is off.
There are two advanced sensors added for enhancing HOBOT’s cleaning
performance and tightening its security while it works on framed and even frameless
windows. The pressure sensor monitors air leakage and the laser sensor detects the
edge of windows.
HOBOT has AI Technology that can calculate paths, auto-detect window edges,
and auto-clean entire windows. It also features a mode for manual operation.

How to clean caterpillar belt
When the device easily slips on the surface of the window, it is because belts are
stained with accumulation of dust and water after each use. It is highly
recommend cleaning caterpillar belts before putting the device away.

Step 2: Turn power switch on, the device’s caterpillar belts continually rotate for 3
minutes.

alert, and flash a red light. The user should take the device down from the glass
as soon as possible.
(3)The safety rope can be used to pull the device back. Gently pull the safety rope
at an angle close to the glass to prevent it from falling off.
How to clean the glass
Microfiber dry-cleaning cloth : it is specifically used for dry clean to wipe partial
dust, dirt off the outside of windows because of its lower friction and poorer water
absorbency.
Microfiber polishing cloth : it can be used for wet or dry clean and suitable for
dust-free exterior windows and interior windows due to its higher friction factor
and better water absorbency.

- 8 - HOBOT Technology Inc.
Spraying detergent on the glass makes HOBOT effectively polish window and
leave window shining. If the device slips and cannot move, please change cloth
to micro-fiber dry-cleaning cloth.
If there is water or detergent on the cloth or glass, the water or detergent will mix
together with the dust or dirt to become mud. Thus, dusty windows must be
cleaned with dry- cleaning cloth as the first step of cleaning glasses, no water or
detergent is needed, exterior windows especially.
Using HOBOT on sunny days or days with low humidity for best results.
The surface of window with water molecules becomes slippery and has
white streaks left on the glass so it is not suggested using the device to
clean exterior windows on rainy or high humidity days.
Remote controller
The device can be remote controlled from the front and back sides. To replace the
battery, just pull down the battery cover.
