What does clogger mean?
A clogger is, at its most general, an agent noun formed from the verb 'to clog': someone or something that blocks or obstructs a passage, channel, or mechanism. In everyday usage it appears most often in practical contexts — hair, grease, wet leaves, and debris are all described as cloggers of drains, pipes, filters, and machinery. The word also carries two older, regionally distinct senses rooted in northern England: a clogger could be a craftsman who made or sold clogs, the traditional wooden-soled shoes once worn by mill and factory workers, or a performer of clog dancing, a lively step dance performed in those same shoes. These occupational and folk senses have largely faded as clogs fell out of everyday wear, though they survive in heritage and folk-dance circles. Today the word is informal and concrete rather than formal, useful when naming a culprit rather than describing the blockage itself.
A person or thing that clogs, obstructs, or blocks something.
"Grease is one of the worst cloggers of kitchen drainpipes."
Informal register; often used attributively before the blocked item, as in 'pipe clogger'.
Chiefly in northern England: a maker, seller, or wearer of clogs (wooden-soled shoes), or a performer of clog dancing.
"Her grandfather worked as a clogger, cutting wooden soles for the local mill workers."
Historical and regional; survives mainly in folk heritage and clog-dancing communities.
Regular plural; used for both the obstruction-causing sense and the historical occupational/folk sense.
"Wet wipes and fat are among the most stubborn cloggers of city sewers."

Etymology of clogger
Clogger derives from the verb 'clog', which entered Middle English in the fourteenth century, probably from a Scandinavian source related to Norwegian 'klugg' meaning a lump or mass attached to something. The verb originally meant to encumber with a heavy weight or lump, later extending to blocking passages and channels. The agent-noun suffix '-er' produced 'clogger' in the sense of one who or that which clogs, while the occupational senses relate to the noun 'clog', the wooden shoe, itself named for the chunk of wood forming its sole. Cognates include Scandinavian words for lumps and clods.
How clogger is actually used
The agent-noun sense ('something that clogs') is common in informal technical and household contexts. The senses relating to wooden shoes and clog dancing are regional to northern England and are now largely historical or folkloric in register.
