I don’t think they come in “buy it for life” varieties.

The closest thing would be a wet/dry shop vac. They won’t apply soapy water to the floor you’ll have to do that separately, but they start around $50, there are a million attachments for different applications, and they will last for ages.

For casual domestic use with a good life span I recommend Tineco. They’re a little bit on the expensive side but they go on sale all the time. Cordless convenience decent battery life, “self-cleaning” functions.

The Rose Anvil did a really good tear down on a pair of doc martens. The consensus in this thread already makes a clear case but this is pretty informative.
