This is a state-of-the-art ultrasonic dishwasher purchased on Makuake, a crowdfunding platform, in August of last year (2025). It uses ultrasound to vibrate water, and the resulting bubbles burst, removing dirt from dishes, vegetables, and tools, and can also be used to thaw food. After a meal, simply fill it with the required amount of water, turn it on, put in the dishes, add a small amount of detergent, and let it sit. After it's done, rinse lightly, and your dishes are clean! ^_^ It was very convenient, but I'm selling it because I'm renovating a used house and will be installing a dishwasher. For those who work in agriculture, you can fill a bucket with water, put the main unit inside, and easily remove mud from farming tools and vegetables. I've lost the instruction manual, so I'll write it here. It's very easy! As explained in the last photo: ① Plug in the power cord. ② Tap the red circle to turn on the power. ③ Tap the light blue circle to select a mode: "Dishes → Vegetables → Seafood" (The time is automatically set depending on the mode.) ④ If you want to create bubbles in the detergent water during washing, tap the yellow circle to generate bubbles from the main unit. ⑤ The power will automatically turn off, but if you want to finish earlier than the set time, tap the red circle again to turn it off. That's all there is to it! Please consider it! ^_^
