• Autonomous Robot Can Clean Floor Size of Football Field in an Hour

02 November 2021

Launching at The Cleaning Show 2021, Rex the robot uses lidar technology to clean 4,032m² - or the size of a football field - in one hour, the highest cleaning efficiency in its size class.

Rex is a king-sized, autonomous cleaning robot targeting commercial and industrial settings, with complete remote handling.

Lionsbot, a Singapore-headquartered smart robotics company, conceptualised Rex during the pandemic with the aim to both empower the cleaning workforce and to keep them safe.

The first Rex robot will be deployed at National Gallery Singapore in December 2021.

"By making robots that cleaners love to use, we aim to give our cleaners superpowers by easing their workload as one cleaner can operate multiple robots at a time."

Cleaning for Airports, Warehouses, Convention Centres and Car Parks

Despite having the same footprint as other robots in its size class, Rex has a 23 per cent bigger cleaning width, holds 23 per cent more fresh water, and has 30 per cent more cleaning efficiency. 

The robot has a battery runtime of up to six hours and a max speed of 1.4m/s, and can clean 4,032m² in an hour – the equivalent of a football field. It has two 16-inch brushes that deliver up to 80kg downward brush pressure, as well as chemical and defoamer dosing functions. Rex is also the first robot in its size class to be equipped with auto-docking capabilities. After each cleaning cycle, it automatically returns to the docking station where it charges and manages its solution levels with automated rinsing and water exchange. This allows robot operators to maintain the Rex with ease without compromising on efficiency.

The autonomous floor scrubber can be operated via three methods – the LionsClean mobile app, a touchscreen interface on the robot’s body, as well as manually with its handlebar.

Rex is powered with a high-definition precision lidar sensor. With 32 lasers, four depth cameras and three sonar sensors, it has a scan coverage diameter of 200 metres, enabling it to scan its environment comprehensively and optimise its cleaning path accordingly. Additionally, Rex’s active obstacle tracking offers a level of safety while providing consistent high-quality cleaning with better localisation and greater accuracy.

“Wonder and Disbelief Reminiscent of Sci-fi Movies”

Ambient lighting and in-built speakers on the machine contribute to the robot’s personality, designed to conjure up feelings of wonder and disbelief reminiscent of sci-fi movies while not compromising on performance.

Dylan Ng Terntzer, CEO and Co-Founder of LionsBot, said: “We are thrilled to unveil the Rex to the world. It is jam-packed with technical prowess and we are confident that every operator will love to have a Rex as their day-to-day work companion. At LionsBot, we refuse to stick to the playbook when making robots. We always strive to develop robots that are fun and exciting. Leveraging our track record with the LeoBot, we also want to ensure that our robots are easy to use for everyone. By making robots that cleaners love to use, we aim to give our cleaners superpowers by easing their workload as one cleaner can operate multiple robots at a time.
