Plumbing-Free Water Tank
The built-in tank is the reason to choose this machine. It holds 1.3 gallons, or 5 liters, which is what one cycle uses, so the routine is to fill it before each load and let the drain hose empty into the sink when the wash is done. That makes it workable in rentals where you cannot touch the plumbing, in RVs and in kitchens where the sink is the only water source. AIRMSEN also includes a faucet connection, and one owner went further and plumbed it into the water and drain lines with extra parts and some basic handyman skill. The catch is the fill point. It sits at the top back of the machine, so on an open counter it is a quick pour, but under wall cabinets there may not be room to tip a jug into it. If your only free space is under cabinets, the faucet connection is the way to avoid that, or plan to slide the machine forward each time you fill it. The 60 inch inlet and outlet hoses give some freedom in where it sits, but it still needs to be within reach of the sink.
