I bought a new Bona hardwood floor mop a while ago. I hate the new design!  While I get that try curved mop head is probably supposed to be helpful, it is not good for getting straight To the floor/wall intersection. Also, since there is no Velcro at the ends of this curved Section, the mop surface can’t attach all the way which causes issues with it
Flopping around. 
I really wish they had not changed the design and would give practically anything to get the old way back.
