What does mopper mean?
A mopper is, in its most straightforward sense, a person who cleans floors or other hard surfaces with a mop. The word can denote a hotel or office cleaner, a janitor, or the member of a cleaning team assigned to mopping duties. In older, chiefly British informal English, it also means a person who mopes: someone who is unhappy, sulks, or repeatedly dwells on a problem. That second sense is rooted in the verb “mope” and contrasts humorously with the practical occupational meaning. Although the word is not formal, it remains readily understandable and is often used in narratives, workplace descriptions, or playful references to gloomy behavior. Its unusual range of meanings makes it more memorable than a straightforward job title: the same word can refer both to someone who removes dirt and to someone who seems unable to cheer up.
A person whose occupation or task is to clean floors or similar surfaces with a mop.
"The mapper was called upstairs to clean the guest room."
Common in everyday British and American English and sometimes used more broadly for any cleaner.
Informally, a person who mopes, sulks, or dwells sadly on their difficulties.
"Stop being a mopper and join the rest of us."
Chiefly British, informal, and now somewhat dated or humorous in tone.
The regular plural is used for multiple people employed as cleaners and, in the informal sense, multiple people who mope.
"Several moppers were working in the empty corridors."
One word can describe someone scrubbing a floor or sulking in a corner: a mopper cleans, while the older informal mopper broods.

Where does mopper come from?
The occupational word mopper is formed from the verb “mop” and the agent suffix “-er,” meaning a person who performs the action. A separate informal sense, referring to someone who broods or sulks, is formed in the same way from “mope.” These two derivations explain the word's contrasting cleaning and gloomy meanings.
How mopper is actually used
The occupational sense is familiar in British and American English. The sense meaning a person who mopes is mainly associated with older informal British usage and may sound deliberately humorous or old-fashioned today.
