A new and improved water wand apparatus includes a handle assembly which includes a tubular member which is adapted for conducting water flow in a first direction from a source end to a nozzle end in the tubular member. A nozzle assembly is connected to the tubular member and includes a nozzle-containing wall which includes a connection aperture for connecting to the tubular member. The nozzle-containing wall also includes a plurality of nozzle channels. The nozzle assembly also includes a truncated conical wall assembly connected to the nozzle-containing wall. An apex wall assembly is connected to a narrow end of the truncated conical wall assembly and serves to block water flow in the first direction causing pressurized water to exit from the nozzle channels in a second direction. The tubular member is substantially straight, and the tubular member and the nozzle assembly 16 are symmetrically disposed around a longitudinal axis. The nozzle-containing wall is perpendicular to the longitudinal axis. The nozzle channels are arrayed in a circular pattern on the nozzle-containing wall symmetrically around the longitudinal axis. The nozzle channels are oriented in the nozzle-containing wall in a range of spray angles ranging from 0 to 60 degrees with respect to the longitudinal axis. A manually-operated valve assembly is connected to the tubular member for controlling water flow through the manually-operated valve assembly, the tubular member, the nozzle assembly, and out the nozzle channels.
