I feel that the most cost-effective is still the Sami magic mop on Taobao. The mop brand, after using it, feels good - it's a great mop. The task is completed, so you can do it, but don't you need your own photos and video materials? Qiaofeng mops should have them, but I'm not sure. It's very good, I've used it before - it doesn't shed hairs. What brand of spin mop is good? Sturdy and durable.
