When I first saw the word "Window," my mind went in a few different directions. I thought about things like "panes," "glass," or even "screens." It was a bit too broad to make a solid guess right away, but I kept the idea of maintenance or structural parts of a house in the back of my head. I wondered if the theme might be "Parts of a Building."

Then the second clue, "Pipe," popped up. This made me pause. A pipe and a window don't have a lot in common structurally, but they both need maintenance. I briefly thought about "plumbing" or "repairs," but "Window Repair" and "Pipe Repair" felt a bit clunky. Then I remembered "Pipe cleaner"—those fuzzy wires kids use for crafts. I checked if "Window cleaner" was a thing, and of course, it is.

By the time "House" appeared as the third clue, the pattern started to feel much stronger. "House cleaner" is a very common term. At this point, I was fairly certain the connection wasn't about the objects themselves, but rather a word that follows all of them. I was looking for a common denominator that turned these nouns into a job or a specific tool.

When "Street" came out as the fourth clue, it sealed the deal. A "Street cleaner" is those big machines or people who keep the city roads tidy. It fit perfectly with Window, Pipe, and House. I didn't even really need the final clue to know where this was going, but it's always good to have that confirmation.

The final clue, "Vacuum," was the easiest of the bunch. A "Vacuum cleaner" is a household staple. Seeing all five words together—Window, Pipe, House, Street, and Vacuum—it became crystal clear. Every single one of these words is a prefix to the word "cleaner." It’s a classic Pinpoint puzzle where the link is a common suffix that changes the meaning of the clues into specific roles or tools.
