Thanks I might look into the enjo.

I mop about 2 a week at the moment and I still get black feet from walking bare foot (I know DH calls me a gypsy because I hate wearing shoes at home!) Its gross and drives me nuts!! figure the streaks are actually spread out grime etc.

Do I need to mop more? What am I doing wrong! Will the enjo get rid of it?

I'm thinking scooting around my house on a towel might be the answer :S
