I've had this for a couple of months now. I honestly haven't found a problem with it. I'm pretty analytical and discriminating, and I think that if you think you would appreciate this product as described, you will be pleased. I use the Mint after I use my Roomba. I have an open concept home, and my kitchen, dining, and living room are basically one room of about 800 square feet. It handles the entire area with no problem at all - wet mopping (which takes more effort for the machine.) I read some reviews that suggested the machine gave off so much water that it would be bad for hard wood floors. I'm pretty careful with things, and I really don't see this as a problem. It is just like a damp mop and it doesn't get the floor wet anywhere. I like using it in the winter to increase the humidity in the house. (Also, our dog tracks a lot.) I think in the summer it will be sufficient to use the dry setting. As an experiment, I put it in the mud room one day, and the mudroom was literally muddy. It did a fine job. Super easy to set up. You can't set it to run at some future time like you can the roomba, but that is okay because the mint is quiet.
