Years ago, I heard a joke that the only tools a homeowner needs are two fold. Duct Tape and WD-40. If it moves and you don't want it to, use duct tape. If it doesn't move and you need it to, use WD-40.
Very funny, I know, but what household can function without both things?
So, while they don't do every household task, they are indispensable.
I wish to include another tool that no household should be without-- the under-appreciated seam ripper.
The seam ripper is a sewing tool that can be found in any sewing section part of a department store or even a quilt store. They can be purchased for 98 cents or you can go all out and purchase an ergonomic styled one that is slightly bigger that the one pictured. The classic model is about half the length of a Bic pen and just as slim. The ergonomic designed one is slightly thicker.
Now, what does the seam ripper do?
The seam ripper was designed with a hook on the end that you slip under stitches and gently yank the stitches out. This destroys the stitch, but leaves the fabric intact.
The seam ripper is great for cleaning things that have hair wrapped around them, like the rollers on a vacuum, used hairbrushes, grates in fans, etc.
This simple tool is so useful that I keep one in my sewing area, one by my hairbrushes and one by the vacuum cleaning supplies.
