Chosen a CES 2019 Best Of Innovation Award Honoree and CES 2018 Editors’ Choice

Energy Efficient

Save up to 80% water and energy each time you wash dishes.

Compact Size

Fits anywhere in your rental, home, business or RV for added convenience and comfort.

Water Purity

No heating elements ensures no mineral or sediment build up.


Tetra is powered by Heatworks' patented Ohmic Array Technology.

This allows for precise temperature control — you can easily clean baby bottles, wash plastic storage containers without melting, cook seafood, clean fruit, or run a load of wine glasses on a gentler cycle. All in just minutes per load. Since water is used as the heating element, the hot water is purer than water from any other dishwasher available in the industry today.

"Tetra takes just 10 minutes to wash dishes. It requires no plumbing hookup—just pour in half a gallon of water. It can also cook food sous vide, and because it heats water up to 180ºF it can even sanitize baby bottles."
