A power unit for a conduit cleaner. The conduit cleaner has a motor with a housing carrying a shaft that is rotatable about an axis. The motor operates i n response to the introduction of a pressurized fluid. The housing has inlets for admitting pressurized fluid and an outlet to permit the discharge thereof. A noz zle is connected to the housing and is configured to direct fluid from a pressurized supply to the housing inlet and direct fluid discharged from the outlet out of t he power unit. The nozzle has a substantially cylindrical outer surface. In one for m, the nozzle does not project beyond the cylindrical outer surface. Accordingly, a compact unit can be made according to the present invention. The absence of radially projecting structure also avoids protrusions that may intercept roots o r other foreign matter within a conduit and thereby interrupt free movement of the conduit cleaner through a conduit.
