A conduit cleaner, particularly adapted to clean sewer lines and remove tree roots therefrom, includes a tube connected to a hose supplied with pressurized water, a jet nozzle on the tube's other end, and forward and rearward guides separated by an intermediate brush. The guides and brush are severally mounted on the tube for independent rotational and limited sliding movement relative to the tube. The jet nozzle has a plurality of openings, which direct jets of discharged water rearwardly toward the distal ends of the brush's bristles. In use, the conduit cleaner is pulled rearwardly through a conduit while the water jets continuously flush the brush. The cleaner has been found effective to dislodge accumulated caked materials, and, with relatively stiff tine-like bristles, to shear tree roots which have penetrated the conduit.
