Bubble Cycle / Washing extenders installation

We discover the elder people is hard to handle the washing liquid container which are upward 4 kgw. That is hard to take the bottle top by one hand, and pour the bottle by the other. And the washing extenders emphasize the green issue for the environment. But the problem of replenishing is troublesome and inconvenient. That is the main reason that washing extenders are not universal and diffusive, and the reason that users would rather buy a pail of the new washing liquid than use the washing extenders with the old one. So, we design a washing installation suits users and the extenders.
