22 such as a bolt that is threaded through the roller 16 alternatively linear bearings that allow for smooth rotation of the rollers 16 may be employed as will be appreciated by one skilled in the art the present invention may be scaled or otherwise altered to accommodate various sizes and types of conduits for example the support arms 18 and placement of the rollers 16 thereon may be altered to produce varying offsets the angles between support arm pairs may also be altered to accommodate different sized hoses for example larger diameter hoses will require a larger offset to yield a large bend radius to prevent hose kinking referring now to fig2 the present invention as employed on a conduit opening 8 is shown more specifically a fluid nozzle 26 and hose 20 which is adapted selectively engage the rollers 16 of the present invention are shown in operation inside the culvert 12 within the culvert a plurality of jets 24 are used to perform high pressure treatment or cleaning of the culvert 12 the high pressure fluid 24 is created by a nozzle 26 wherein the fluid is supplied from a truck or other fluid supply source via the hose 20 the rearward force of some of the jets 24 propels the nozzle 26 further into the culvert 12 and directs waste out of the conduit 8 thereby cleaning the selected portion of the conduit 12 once complete a spool on the truck is activated thereby rewinding the hose 20 and removing the hose 20 and nozzle 26 from the culvert 12 in one embodiment of the present invention a.
