Drain Portable While Upstairs

I always dump my dirty water down the clients toilet...just make sure not to leave the toilet looking dirty when you leave.

1)  How do you get it into the toilet?  Is there a drain hose that I am missing?
Oops, I think I just figured it out.  I called a local supply house and they told me to simply drain it in a bucket.  So simple.  I feel stupid!
2)  Don't I lose pressure if I have such a long run of hoses?
Also, they told me 50' should be OK!

I have a Ninja Portable and wondering how does everyone drain there units when upstairs?   Is there a way to drain the unit into a tub or something?  I believe that I am missing something in my novice carpet cleaning experience.  Is there a drain hose that I can purchase or does everyone simply leave the machine downstairs and attach a long hose tor each upstairs?  I usually just take my machine out back and let it drain into the yard.  That is probably wrong, too.

Help.
