In the US (although from the term "binman" I believe you are not US), residential trash pickup and street sweeping are generally jobs that are mostly driving a vehicle. Dense urban areas still use trashmen on the back of trucks.
Those professions are both solid blue-collar jobs. Many of them are union jobs in the US. They are looked down on for a couple reasons, IMO: Advancement. What does "moving up" mean? Most people don't want the same job for 30 years. Second, dirty/smelly. Those are not considered attractive working conditions.
Would I do either? I might consider starting a business as an independent street cleaner. There are many businesses that contract out having their parking lots cleaned. Add pressure washing services for difficult to clean areas, or benches etc. You would probably be working a lot at night when the parking lots are empty.
As a child, and even now at age 55+, I am still fascinated by heavy equipment operation. That was the job I wanted as a kid. I ended up being a computer engineer. I joke, that my "retirement job" will be working at a rental center that rents backhoes. I could still "play" with them but don't have the cost of ownership.
