Inventing a washing machine that doesn't require electricity.

The "green" washing machine could revolutionize households in the near future.

Despite the rapid development of science and technology in recent years and the significant improvement in the overall quality of life, many places around the world still face basic daily challenges.

A specific example is washing and drying clothes. Using automatic washing machines instead of manual labor remains a luxury in places without abundant water resources or sufficient electricity to power them.

GiraDora models also come in a variety of colors.

Laundry, seemingly a simple task, is actually a problem in many disadvantaged areas around the world.

In arid towns and villages far from water sources, laundry was considered a time-consuming and arduous process, not to mention its long-term negative effects on the health of the workers.

This strenuous work causes a range of ailments such as tendonitis, chronic back pain, painful and dermatological problems in the hands, and especially asthma.

Because of the distance from clean water sources, residents have to spend hours transporting enough water for each laundry cycle. According to research by a pair of students from Los Angeles, USA, along with related organizations, residents of Lima, a town in Peru with a population of 30,000, wash their clothes an average of 3 to 5 times a week.

Each wash cycle can take up to six hours, including fetching water, hand washing, spinning, and drying. Therefore, Alex Cabunoc and Ji A You, the researchers who published their study, invented GiraDora, a washing machine that doesn't require any external power source and consumes only one-third the amount of water compared to traditional hand washing.

GiraDora is a solution that supports disadvantaged families.

Each wash cycle with GiraDora takes only 3 to 5 minutes. GiraDora also integrates a spin-drying function. According to Cabunac: “People now spend too much time, energy, and resources on the most basic and essential things in life. Cooking and laundry now take up too much precious time, time that could be used for productive work to free themselves from poverty.”

The success and usefulness of GiraDora has inspired many new versions, including Up-Stream, which costs only $4.

The success and future of "mechanical washing machines"

Drumi is a more "urbanized" version, aimed at affluent families. It costs $180 USD (approximately 4 million VND) and can be ordered now. The manufacturer plans to begin shipping Drumi to homes in November 2016.

The GiraDora is priced at $40 (approximately 1 million VND) and targets families with incomes ranging from $4 to $10 per day. The team is currently continuing to experiment with new device models and research needs in various regions around the world, including Africa, South America, and India. Therefore, GiraDora is not yet officially available for sale to the general public.

Although not yet released, BMW promises to be a useful device for those looking for motivation to exercise.

If you don't fall into the aforementioned disadvantaged group, you'll have options for the general public such as Drumi, BiWa, and BWM.

BiWa is still in development and is likely aimed at those who want to save time as much as possible, as it can help users exercise, do laundry, and get to work all at the same time.

How to use and the structure of GiraDora

GiraDora's structure is quite simple:

The usage is equally simple:

Beyond investment and charitable grants, GiraDora and many other smaller inventions have truly helped to ease the burden of difficult lives for some people.
