Honestly it's just worth it. Effortlessly cleans the floors. I have sealed marble floors and it's so easy to use. Sometimes I can see little circular marks from the mop pads. But I don't care because I can't see dog paw prints anymore. With 2 dogs and a baby this is it. This is the one. I use my own solution, though it is advised not to, and it works great. I won't be buying their solution because I don't like strong smells or toxic cleaners.
