We really like this vacuum for several reasons.  It has a huge canister that does not have to be emptied after cleaning every room.  Because we have pets, we vacuum lots of hair and smaller canisters fill up way too fast.  It is powerful, has 3 great settings (hard floors, carpet, area rugs) and other nice features such as easily removing the wand for edges and the canister is so easy to completely empty.  Because it is a Shark and we own other Sharks, it is bigger and bulkier than I expected, but otherwise we like everything about this vacuum!
