Completely agree. My mop was about a tenner a few years ago. Not even sure where it was from now as I've had it so long, but like yours it has a removable pad that can go in the washing machine. I throw it in with the towel I use to dry the floor (can't leave the bloomin' kitchen tiles to air dry as they just go streaky
) the towel I use to dry the cat when she comes in soaking wet and the floor mats.
Everyone is becoming so much more conscious these days of plastic use and trying to cut down and reuse things, but the amount of waste she has would fill a landfill site on its own.
