[origin: EP3662804A1] To provide a cleaner head and an electric cleaner (1), which can quickly remove dust having entered between the brush hairs of the roller brushbar using the rotation of the roller brushbar. A cleaner head (26) includes: a cleaner-head body (32) having a suction opening (28) that is provided in the bottom face, a suction chamber (63) that connects to the suction port (28), and a relay pipe (66) that connects to the suction port (28) through the suction chamber (63); a brushbar (29) that is disposed in the suction chamber (63) that is rotatably supported by the cleaner-head body (32), and that has brush hairs (65) extending in a normal direction; an electric motor (31) contained in the cleaner-head body (32); a power transmission mechanism (51) that transmits drive force from the electric motor (31) to the brushbar (29); and a brush-hair dust-remover (55) that protrudes from the inner wall face (71) of the suction chamber (63) to be in contact with the brush hairs (65) and restricts air sucked into the relay pipe (66).
