A spray can to represent spray paint, insect spray, or spray lubricant.
There's a power plug but no power socket.
There's no staples or stapler.
There are no appliances—no oven, microwave, toaster, mixer, washer, or vacuum cleaner.
There's no traffic cone.
I believe those are all trademarked. Unicode tries to avoid those.

Interesting idea! I wonder if there'd be any interest in getting wider coverage of other bitmap paint tools: rectangular selection, lasso, paint bucket...
> There's a power plug but no power socket.
That's problematic from a localization perspective, as electrical sockets vary widely from country to country, and some of them may be difficult to recognize as a socket at a small size. For example, some European countries use a socket which is made of three circular pins in a straight line -- it'd just look like an ellipsis.
Besides, there isn't a lot of symbolic meaning that's conveyed by a socket that couldn't be expressed just as well with a plug.
> There's no staples or stapler.
Maybe. There isn't a lot of symbolic meaning to these either, though.
> There are no appliances—no oven, microwave, toaster, mixer, washer, or vacuum cleaner.
A lot of those will just look like white boxes at text size, and -- again -- they don't have a lot of symbolic meaning.
You might be able to make a case for an upright vacuum cleaner, though, since that's visually distinctive and is associated with cleaning.
> There's no traffic cone.
Oh, I like that idea. It's got some symbolic meanings, too, like "warning" and "under construction". There is already a construction sign (U+1F6A7), though.
For cleaning, a broom is probably better than a vacuum cleaner.
A broom already exists 🧹
The Bluetooth logo is two runes, which perhaps could have a zero width joiner between them in iOS emoji abuse style.
The traffic cone would be good for VLC! They could give rename their app so the name matches the icon :-) That got me thinking: are there any common apps that use emojis in their name?
The mouse pointer symbol.
