DiamondGirl - Can I ask where you got your electro static mop from and what brand it is?
My electrostatic mop is the 'OATES' brand and is orange (all their products are colour coded). It wasnt cheap, but its really good at attracting the dust and rubbish on the floor. I got the extra wide brimmed version. There are other brands available that claim to do the same thing, but I dont know if they are any good. Oh, and I got it from Bunnings. Technique is important, you must keep it flat on the floor with the brush hair facing outwards while 'dry mopping' to keep the brush statically charged and therefore best able to attract the most dust.
