Last night my wife and I were informed that our newly purchased home has a root problem in the main line. Obviously, we weren't too excited about this news. The folks from Roto Rooter pulled out 3 lbs. of roots as well as some raw sewage. The roots are out, but some of the sewage remains on the basement floor. I am considering going to purchase a wet/dry vac to clean the floor tonight and wanted to get some opinions on the way to go. On one hand it would be nice to have a good model for future use. On the other hand, it's first use will be for raw sewage. Maybe that should be it's only use? Would you recommend getting a model to last a while or just for one nasty job? What type of wet vac would you recommend?
