I've given lots a go . I really don't like the ones with strips (they have a name apparently), if you don't have much strenth maybe for for the cotton thready type ones that has a squeeze thing that you push down over the top. The head isn't too big - just don't leave it on water overnight cos it can swell a bit.

I also have one of those flat sponge thingo ones - they are ok too.

I will NEVER make a decent mop salesperson.....
