The Chinese start-up CleanseBot has developed a device of the same name that allows travellers to disinfect surfaces in rented accommodations and hotel rooms. Using UV light, 99.9% of bacteria, germs and dust mites in a room are killed. The robot can also be placed on a freshly made bed to kill all bacteria on the sheets by moving back and forth over the bed. It can also be used to disinfect electronic devices. The battery operating time of the "CleanseBot" is up to three hours.
