As professional cleaners we are often called in when clients give up on their darker hardwoods/ laminates. While they do take a little bit more work to get right, it is not impossible, it just takes practice.
First get a good floor care product made exclusively for laminates such as Bona X
http://www.florstor.com/BonaLaminate.html1) pre-vacuum the floor to remove larger dust/ debris
2) lightly spray the floor, remember a little goes a long way. Work in small sections to avoid the spray from drying.
3) work backwards, do not walk back over the damp floors until throughly dry
3) Use the microfiber mop in the same direction all the time rather than in a more common back and forth mopping motion as this action will cause some of the dust, ect to be redeposited back onto the floors
it may take a time or two to get used to this routine, however once perfected you will love your darker floors, I promise
