This was my first time using Shinebot and I was willing to return it if it didn't work properly. I have to say I was very impressed. It wasn't perfect, but it certainly worked well, as you can see in the dirty water photo I've attached. There are only two of us here, but I have a large wooden floor that has done its job perfectly. In several places I followed it with a dry, soft cotton mop so that the floor would not withstand water for long. It did a good job and I didn't use the cleaner this time thinking I might have to return it. Next time I'll add some cleaner and it should work even better. My floor shines! This is the goalkeeper.
