Once I received it, it was partially charged, so I went ahead and started scrubbing right away. It was able to clean the soap scum off my tub and shower walls very quickly. You do need to add a little bit of your own elbow grease with some pressure, but it does clean extremely well. The only downfall is I wish the charge lasted longer. It does last long enough for a normal, weekly, deep cleaning.
I was also able to scrub my toilet sinks, and I did my mirrors with the glass mirror pad. I haven't used all the attachments yet, but I have used 4 of them and they work great.
Charging takes a couple hours. Get back to a 100% from 0. I do like the wall hook it came with, so I'm not trying to find another place to the store a clean product.
