The deep cleaning included the hygienist, Karla, using a water pic, hand scaling, and finally polishing my teeth. It took two separate visits - about 5 hours total - to do all that. The hand scaling was probably the worst part - the hygienist had to really put some weight into the job and actually had to stop to rest her hand during the second visit.
