The Shark Hydrovac takes me more effort to keep the floors clean. The canister filled with dirty water and debris smelled really bad when left for a day. Like I was walking around wondering what is rotting?? Also, the self cleaning cycle when done, if there's water left in the clean water canister,  the water spills out all over the floor. Also, I don't think the liquid cleaner smells good. The vacuum feature is a good one. The filter was also very disgusting when I tried to clean it. Water, dirt and hair mixed together dint mix well
