I seem to be cursed with mops. This is unfortunate, seeing as how I have three small children that constantly spill things on the kitchen floor (along with their father and his near-constant coffee spilling . . .), leaving me with a kitchen floor that more or less ALWAYS needs mopping. I should do it every day. I don't.
Partially this is because I really don't like mopping, but also it's because I never seem to have a satisfactory mop. I prefer the sponge mops, because they're simple to use and light. A bought me one a few months ago. I mopped at least once a week because it was so easy and worked so well . . . until it didn't. There was this weird design flaw where the inside part kind of untwisted and the head fell off and there was no way to thread it back on because the screw part was on the inside.
I only know this because I asked A. to put it back together for me and he spent, no lie, 45 minutes messing around with the thing before I finally grabbed it and threw it in the trash. I wasn't even the one trying to fix it and it was making me mad.
We had another sponge mop handle in the shop that just needed a replacement head. That mop was purchased at the grocery store. I went to the same grocery store and bought the same brand of mop head as the one we got before, the only kind of replacement head they had.
It didn't fit. OF COURSE IT DIDN'T. They probably change the design every few months or something so you have to buy a new mop.
This left me with a string mop the MiL had bought awhile ago. It had all these screw parts I couldn't figure out and it was so long that it didn't even fit into my bucket.
THIRD FAIL AND SCREW THIS.
I ended up on my hands and knees scrubbing the kitchen floor with the useless new replacement head because I couldn't return it and it works okay as an extra-long sponge. There was a lot of swearing.
But at least my kitchen floor is clean now. For about an hour.
