We've had one for several years.
Here's how we rig it so that we can use the same hose to run the eductor and flush the tank at the same time.
Because of the water demand, we prefer not to use when away from home. The old 3in corrugated hose is just fine.
At home it is excellent. In town, you could run the discharge hose to a convenient sewer clean out. But we are out in the county, on a septic system. It is about a 100ft run with a 3 1/2ft rise to the septic clean out we prefer to use. Because of the cost, we did not buy any extra hose, other than the piece that it comes with. We did buy 10 lengths of 1" pvc pipe. Bigger is not better. We glued a union on one end of each piece. That allows us to assemble/dissemble a run from Miss Winnie to the clean out. (One of these days we will entrench the assembly to make it permanent, just haven't.) . Normal water pressure handles the distance and rise just fine. Caveat: if you go this route, plumbing el's are not your friend. Use 45's or lazy sweeps.
It is interesting to watch in operation. The knife blade nozzle opening just slices up anything that flows out of your tank. Except Shopkins. Don't let your granddaughters flush Shopkins!
Our two cents.
