Thanks for finding that. I guess I am to old to be tech savvy. There was another pic that shows both devices. The pipe has holes drilled in it to suck up muck it is attached to unistrut the flat plate behind it is to scrape the muck and keep it by the pipe. There is a yoke attached then a rope. You hook the flexible hose to the intake of the pump set the device in the pond and slowly pull it across the sweep of the hose if your muck is really deep it will work its way down I then pull it enough to get it back to the top of the muck and let it work back down.
