With this dishwasher you won’t need a plumber or a scrubby sponge. Heatworks’ Tetra countertop dishwasher is all electric, requiring no plumbing hook-up. It simply sits on the counter, plugs and cleans up efficiently using 3 liters of water & Ohmic Array Technology that sends a current through the water to clean without scrubbing. The company claims it cleans “50% more dishes using 40% less water in 55% of the time than the leading dishwasher brand.”
