clutterer

One who accumulates

A clutterer is someone who clutters—who accumulates and fails to organize possessions, creating disorder.

The term appears in self-help contexts for people who struggle with compulsive acquisition or difficulty discarding things: As a recovering clutterer, she now thinks twice before buying anything.

Less commonly, clutterer describes anyone who makes spaces messy or disorganized.
