ROOM Shampoo, let anyone wash their hair anywhere hassle free. Room Shampoo is specially designed for the elderly and disabled people which find it difficult to find a place to bath and wash their hair. By simply plugging Room Shampoo to a household vacuum cleaner (with suction power of 400W or more), the ROOM Shampoo can wash and suck dirty water simultaneously. Water will not spill out and the user can just sit or lay down on the bed for a thorough cleaning. ROOM Shampoo is a patented product with a special design which also reduces the use of water. It normally consumes 1L of water in one wash. Longer time and more water might be required for users with longer hair.
