Query: Very Disappointing product!

I was very excited to get this product but I have returned it because it doesn't do the job. On the tv commercial it shows a woman effortlessly swiffing it around the floor, but in reality it is really hard to push when it is washing. My shoulder ached after doing one small room, it would have been easier with swiffer mop. I think they have used false advertising for this product.
