Turbo, rotary, variable and multi function nozzles. A turbo nozzle spins a pencil jet in a cone, so you get the cutting power of a zero degree jet over the coverage of a 25 degree fan. On concrete, brick and heavy grime it will do in one pass what a fan nozzle does in three.

Match the nozzle orifice to your machine flow and pressure - this matters more with turbos than with fan nozzles, because an oversized orifice drops your pressure and a small one stalls the rotor. Ceramic seats last far longer than steel. Variable and multi function nozzles trade some outright performance for the convenience of changing pattern at the nozzle, which suits general contract work more than production cleaning.
