This is an ultrasonic washer, convenient for removing stains from clothes. You can remove stains by slightly wetting the garment and using it in a sink or a bucket! It's rechargeable, so you don't need batteries. I bought it about 3 years ago and used it at first, but I couldn't get the hang of it because I'm a bit lazy. I've been storing it in the box. * The instruction manual is slightly folded at the top, but you can read it without any problems. Please refrain from purchasing if you are concerned. * Shipping will be done by taking the item out of the box, wrapping it in bubble wrap, and shipping it carefully. * Returns are not accepted after receipt.
