When the board opened with Window, I did what a lot of solvers would do and parked it under household chores. I was half-expecting the next clue to be something like Dishes or Laundry. Then Pipe arrived and pulled my brain toward plumbing or DIY projects instead. By the time Dry showed up, I was juggling errands, tools, and laundry in my head with no clean category to put them in. Street made things even stranger. Window, Pipe, Dry, Street — that sequence had me flirting with ideas like things you wash, types of jobs, even places you see signs. None of those felt solid once I tried saying each clue aloud. The pattern finally clicked when I stopped chasing topics and started testing the same word after every clue. Window cleaner → spray used on glass Pipe cleaner → craft wire once used to scrub pipes Dry cleaner → service that cleans clothes with solvents Street cleaner → vehicle that sweeps debris off roads Vacuum cleaner → appliance for floors and carpets Once I heard that rhythm — window cleaner, pipe cleaner, dry cleaner, street cleaner, vacuum cleaner — all the earlier theories collapsed at once. Household chores, plumbing, and "things you wash" each miss at least one clue, but "words that come before 'cleaner'" fits every clue naturally. That clean fit is what locks in the connector.
