This unit uses nano-technology (Nano Lotus Effect) to make cleaning easier in the future. Powered by a rechargeable lithium-ion battery, Nanophea Robot vacuum cleaner will automatically return to its charging station when it runs out of power, thanks to its infrared sensor. Nanophea diffuses the water and spread it around, these bright pearl-liked water drops attract dust particles which then sucked into the receptacle. This cycle repeats itself using the same water which has been filtered. Nanophea only measures 12 centimeters (4,7”) in height, thus allow it to move freely under furniture. This robotic vacuum cleaner is equipped with a smart scanner at the front of its body to detect a dirty area.
