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

Energy Efficient

Handwashing dishes uses 10x the amount water than dishwashers. With Tetra, you'll save water, energy, and your relationship.

Compact Size

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

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 — easily clean baby bottles and wash plastic storage containers without melting, clean fruit, or run a load of wine glasses on a gentler cycle. All in just minutes per load. And since there are no metal heating elements inside to rust, the hot water is purer than water from any other dishwasher available in the industry today.

Did you know that handwashing dishes takes 10 times more water than using a dishwasher? If a 2-person household were to switch from handwashing to a dishwasher for one meal a day, they could save 1500 gallons of water in a year.

Preorder is slated to begin in 2021.

We've spent the last year conducting market research and working with industry partners and engineers to bring Tetra to life and anticipate a high demand. Get updates on our progress by providing your email address below.
