Before getting the SharkVac, I wondered if we REALLY needed another appliance.  But the ease of having the SharkVac out and ready is a game changer.  It's so convenient for keeping our kitchen floors clean with 2 little kids.  And my 5 year old loves to use it too!  It's awesome that it vacuums and mops, and that the mop fluid is in the SharkVac so no need to add fluid each time or apply a fresh pad.
