I agree with everyone else. It does take time and she will get the hang of it. My baby still has accidents on the floor sometimes too and she is 10mths. Just give it some time. Also I have heard that they dont like to go on a wee wee pad that is already fairly soiled. I have to change the pads alot with Dolce because she is such a Miss Priss that she even lifts her leg sometimes so she doesnt get it o her feet.
Your baby will get the hang of it sooner or later, dont worry. Oh and I love Nature's Miracle, let it sit for a while on the linoleum and then clean it up, this usually lets it seep in and takes the smell away better.
