Is that a vacuum cleaner that can suck water, or are there vacuums that use water to clean the exhaust like scrubbers on ships do?

There is actually, it’s called Rainbow Vacuum. They used to (maybe still do?) sell them door to door MLM style but the vacuum is actually good in my experience with them.

My mother has one of these, but I didn't know its name until now! I actually remember the salesman coming to our home and showing us how it works. It's still going strong ~25 years later. I'm currently using a Miele something, but I'm always a little weirded out by the fact I have to change vacuum bags, because when I grew up we would just flush the dust down the toilet after vacuuming.

Now that I know what my mother's vacuum is called I'm a little tempted to get one myself...

Funny thing as it pertains to this thread is the Rainbow salesmen used to sell an air freshener or early essential oil to add to the water. I can recall the smell perfectly now

Probably works like a water pipe aka bong

To sibling comment: bongs cool down smoke, not filter it

[krageon]

If they only cooled it down, the water wouldn't be so incredibly disgusting

I tested this in college, they definitely also filter it. Just not very well. But 3+ chamber bubblers do filter fairly well.

Still, if you’re looking for that, edibles and temperature-controlled vaporizers are way to go.
