Here is another robot that can help you keep your house clean. Mofa is a compact robot that cleans floors with microfiber materials attached to its bottom. The robot can get dust, pollen, and particles off of your floor. It does not make a noise or exhaust gas. The device measures 235 x 80 x 235mm and weighs 1.1 lbs. It can run for 1.5 hours on battery. How it stacks up against other robotic vacuums is anybody’s guess.
