OVER 50% of the tall buildings completed in 2017 were in China - and demand for skyscraper window cleaning in the country is now seemingly on the rise!
Pufeng Intelligent Technology, a startup based in Xiamen, east China, has developed an "autonomous window-cleaning robot" able to withstand winds of up to 60 miles per hour.

Containing over 150 sensors and six different propellers, the robot attaches to tall buildings and scales them using suction cups.
It can work for four hours and clean 1,290 square feet of glass (around 120 square metres) in 60 minutes. The manufacturer claims this makes it “10 times more efficient” than a human undertaking the same task.

In 2016, an estimated 400,000 people worked for window-cleaning companies in China.
In Shanghai alone, there are 3,000 different window-cleaning companies, almost all of which were founded in the last two decades.

High-rise window cleaning, however, does present considerable risks as many workers still lack the costly but necessary health and safety training. There are no reliable statistics for this specific sector, but around 600 lives are lost to falls in China’s construction sector annually.

After its successful outing this month, Pufeng Intelligent Technology hopes to launch small scale mass production of its robot and start marketing its product to developers within the next six months.
