Tuvie says ”Nanophea Robot vacuum cleaner is a domestic floor cleaning robot, futuristic, autonomous and very intelligent. It’s not like the other existing robotic cleaners because it works only on nano surfaces covering with a very little amount of water. This unit uses nano-technology (Nano Lotus Effect) to make cleaning easier in the future. The Nanophea design itself was inspired from the lotus leaf.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 such as your sofa or bed. This robotic vacuum cleaner is equipped with a smart scanner at the front of its body to detect a dirty area”.
