This industrial and scientific cleaning tool is a game-changer for every janitorial and sanitation supplies. Based on my observations the waterproof feature made it easy for me to clean any mess on my floor without worrying about water damage to the device... The suction power efficiently picked up even the tiniest dust particles, leaving my floor spotless. The only con is that the device is quite heavy, but its performance outweighs that minor inconvenience. I highly recommend it..
