About Green Caddy 自潔式拖把桶

Green Caddy係一款自潔式拖把桶，專為減少拖地時嘅用水量而設計。呢個桶只需2.5公升水，相比之下，傳統拖把桶可能需要超過10公升水。桶內裝有中空纖維膜濾芯，可以喺唔需要額外加壓或用電嘅情況下，將乾淨水同污水分隔開。呢個濾芯每分鐘可以過濾超過800毫升嘅水，並去除大部分細菌、微塑膠同雜質。傾斜嘅桶底設計可以將污水收集埋一齊，而中央嘅轉軸則可以喺沖洗同脫水功能之間轉換。呢個濾芯最長可以重複使用一年。

Unique Properties: The patented technique of clean-and-dirty water separation with an additional advanced decontamination cycle function. A filter is equipped within the mop bucket to revert the polluted water; the feature of this filter is that it can filter over 800ml of water per minute without additional water pressure while sanitizing 99% of the containing germs, microplastics, and substances larger than 1000 nanometers. This result shall surpass the general drinking water bacteria count standard of under 100. Furthermore, it can be used repeatedly for up to one year without purchasing replacements.
Dimensions & Packaging: The product is measured at 33.5 by 34.8 by 32.4 centimeters.
The inclined surface design allows dirty water to gather quickly which creates a liquid-level difference, and the 3D squeegee design helps exclude hairs easily. This improves the efficiency and time of the filter to separate the non-liquid particles aside and convert the dirty water in the bucket into pure water. The impurities, bacteria, and dirt contaminated when mopping the floor are filtered out and clean water is used every time the floor is mopped. A third-party detergent could be added to the water purification bucket. The detergent can be reused.

Production Technology: The bucket is made of PP materials, while the most critical part, the filter element, is made of the innovative development, the Pressure-Less Large-Flux Hollowed Fiber Membrane Filter. Since hollowed membranes are often applied on water cleaners, hemodialysis, or other medical equipment, it is without a doubt that the item has outstanding efficiencies of filtering and resisting acid and alkali (pH2-pH14), which is also suitable for environmental-cleaning applications. The high efficiency of the device can help decrease the use of water resources, filter out bacteria, and reduce the time for cleaning and working hours.
Design Challenge: Over forty materials and hundreds of combinations have been experimented with over two years of time prior to selecting a specific hollowed fiber membrane. However, the original hollowed fiber membrane filter could only filter polluted water and germs under added water pressure. Hence, our design team spent another year modifying the overall design and adjusting the membrane ingredients to finally create a product that purifies pollutions, germs, and microplastics effectively at a desirable high speed, without (or under very low) adding other sources of water pressure.
Research: From the initial designing stage to the search for the perfect filter material, two years of countless experiments have finally allowed the team to encounter the perfect material, the hollowed fiber membrane. However, the original filter could only function properly when there is electricity or with added water pressure. Our design team spent another year to find solutions to create a self-cleaning bucket that filters over 800 milliliters of water just in a minute and 99% of its containing germs and microplastics without any added water pressure or electricity.
Inspiration: Since traditional mop buckets usually could require over 10 liters of water to be filled, and the bucket of water would turn dirty in no time after several uses; not only will users need to change it constantly, water resources will easily go to waste as well. Our Revolutionary Self-Cleaning Mop Bucket is equipped with a unique structure and filter design that could require only 2.5 liters of water without changing or replacing. Our design will enable users to use the same bucket of water to rinse and clean the mop with recycled clean water.
Project Duration: The project started in September 2019 and finished in November 2021 in Taiwan.
Operation Flow: This simple-outlined design is paired with a hand-pressuring mop handle and has adopted an easy centrifugal method for washing and drying. In the middle of the bucket, a water-drawing center post is set up to effortlessly switch from the rinse function to the spin-dry function through the movements of the mop handle. At the same time, the filter can be cleaned simply by rotating removed from the bucket and rinsed under the faucet. Since the pandemic outbreak, more people have paid more attention to the cleanness of their surroundings; this product has been tested and shown to increase efficiency for cleaning while conserving water.
