Help, the cellar has been slimed

Well, some of the water is out of the cellar. What was left was a mucky, muddy slime of water and dirt. The pump couldn't seem to pump this heavy water out of the cellar. (I think the pump was too weak.) We started cleaning up with a mop and worried it would take forever. One of our new neighbors walked by and offered us their industrial (wet/dry) vacuum to use. It works. We didn't quite finish it today, but kept up until hunger hit is in the evening. I will take tommorrow off of work as well and finish sucking up the goo.
