Pet hair and dirty water back on carpet

\015 I have a brand new bissell proheat. Used it today for the first time. Everything seemed to work however after I spray dn go back over the carpet to pick up the dirty water I am seeing wet pet hair back on the carpet in clumps. Also turned it off and placed it on the kitchen floor to troubleshoot and dirty water was coming out. This is a new proheat, why is it not picking up the dirty water and not letting it remain in the machine?\015 – Bissell 1698 PowerSteamer ProHeat Upright Wet/Dry Vacuum

Bissell proheat 12 amp

\015 The front end is dragging on the carpet. Have taken out and replaced both windows and still is dragging. What am I doing wrong? When this is going on there seems to be no suction though when I put a piece of paper under it when it’s standing upright I have suction. HELP!!!.Donna\015 – Bissell 1698 PowerSteamer ProHeat Upright Wet/Dry Vacuum
