So called because he was always sweeping. One day he saw Revata in his cell and thought him an idler. Revata read his thoughts, and, wishing to admonish him, asked him to return after a bath. When Sammuñjaní did so, Revata preached to him on the duties of a monk. Sammuñjaní became an arahant, and all the rooms remained unswept. The monks, reported this to the Buddha, who, however, declared him free from blame, since there was no need for him to continue sweeping. DhA.iii.168 f.
