Do not use those lawn rollers that you fill with water to weigh them down - they do not work!
The old fashioned, but very heavy, metal ones do flatten the lawn but unless you know someone with one then they are difficult to find (and are normally rusty).
Unless the electric ones are pneumatic then I cannot see them working, not that I have seen one. You need weight to flatten compacted lawns.
Cutting the lawn and then removing excess soil or filling the dips with soil does work...I have had to resort to the same but you still get bare poatches where the lawn mower hits the high points and then you have uneven grass!
