The Tetra is an a compact countertop dishwasher that cleans in minutes using only 1 gallon of water. With its own water reservoir, no plumbing is required. Instead, water is manually poured into the unit, and dirty water is easily removed via a greywater reservoir. It can be placed on a countertop and plugged into a standard electrical outlet. Tetra uses 80% less water and energy than existing dishwashers. Tetra can wash two full place settings, 10 plates or 12 pint glasses within minutes.
