How do so many of them loose wheels? Are they designed that way?
Mopped/swabbed many a floor/deck in my day. Always hated when you would get a three wheeler and accidentally dump the buck out when trying to wring out the mop/swab.
Honestly I don't know, the mop bucket was broken when I got there. I think only 1 of the wheels actually rolled, so you had to push it across the tile. It did pretty fine until you stopped pushing and a broken wheel got lodged in between tiles. Then the water would slosh out all over the floor. But this new one was scientifically designed not to slosh. It was glorious.
Also there was this one time I went back to find a 100% straight-bristled and grease-free broom to sweep the dining room with! 8DD
