AQUA Dishwashers "ADW-L40B" and "ADW-M28B" Launched, Achieving High Cleaning Power with Approximately Half the Water Usage of Conventional Models

AQUA Corporation (Headquarters: Chuo-ku, Tokyo; Representative Director and CEO: Jingguo Du) will launch its large-capacity tabletop dishwasher "ADW-L40B" and slim model "ADW-M28B," which support both tank-type and branch water tap-type water supply, on Wednesday, May 13, 2026.

AQUA dishwashers powerfully spray high-temperature, high-pressure water jets while the upper and lower nozzles rotate 360 degrees, thoroughly washing away greasy stains that are difficult to remove by hand. Furthermore, they are characterized by higher water-saving efficiency than handwashing, as they wash by circulating a small amount of water like a fountain and only replace the water during rinsing.

The latest models to be released this time offer more choices in "water supply methods" and further improved "water-saving performance." In addition to the previously adopted "branch water tap type," a new "tank type" water supply method, which requires no installation work, has been added, allowing for installation tailored to various living environments. Moreover, through water flow control, the water consumption per use is approximately 5L (※1) for "ADW-L40B" and approximately 4.5L (※1) for "ADW-M28B." Compared to our conventional models (approximately 10L to 10.5L) (※2), we have succeeded in reducing water consumption per use by about half.

These products, equipped with high cleaning power and water-saving performance, can help streamline household chores.

※1: Water consumption per use for the tank type. For the branch water tap type, "ADW-L40B" is approximately 6.8L, and "ADW-M28B" is approximately 6L.

※2: Water consumption for conventional model "ADW-L4A" is approximately 10.5L, and for "ADW-GM3" is approximately 10L.

【Main Product Features】

① Cleaner than handwashing! Supports "tank type" for immediate use after purchase & convenient "branch water tap type" for automatic water supply

② Achieves even greater water saving! 40 dishes (※3) equivalent to 5 people can be washed with approximately 1/15 of the water used for handwashing (※5)

③ Two sizes and two colors to choose from, according to installation location and lifestyle

●Cleaner than handwashing! Supports "tank type" for immediate use after purchase & convenient "branch water tap type" for automatic water supply

The upper and lower nozzles rotate 360 degrees, powerfully spraying high-temperature, high-pressure water jets. This powerful water flow not only blasts away stubborn dirt during washing and rinsing but also sterilizes (※9). Washing with hot water up to approximately 75℃ allows for thorough cleaning of greasy stains that are difficult to remove by hand.

Furthermore, there are now two water supply methods to choose from: the "tank type," which requires no branch water tap installation and can be used immediately after purchase, and the "branch water tap type," which provides automatic water supply without hassle, allowing for installation tailored to various living environments.

●Achieves even greater water saving! 40 dishes (※3) equivalent to 5 people can be washed with approximately 1/15 of the water used for handwashing (※5)

Handwashing requires a large amount of rinsing water, but dishwashers save water by accumulating a small amount of water and circulating it like a fountain for washing. During rinsing, the water is replaced, and less foam is generated, achieving high water-saving efficiency. Because it is used daily, it is designed to be gentle on both household finances and the environment.
