A spray device for cleaning residue from a filter member. In one embodiment, the spray device includes a tubular stem telescopically slideable in a sleeve. A coil spring surrounds the stem and resists movement of the stem out of the sleeve. A tubular halo with nozzles is fastened to the end of the tubular stem so that when a pressurized fluid is applied to the stem, the stem is forced out of the sleeve against the spring force, thereby causing the halo to travel along a cylindrical filter surface. The pressurized fluid is also jetted from the nozzles and cleans the cylindrical surface. When the pressurized fluid is removed from the spray device, the spring retracts the stem and the halo back to a rest position. In another embodiment, the halo is replaced with a nozzle head that moves within a cylindrical filter surface to be cleaned.
