This is my first time using a 3-in-1 vacuum, and I am absolutely in love with it! Before you use it, remember to charge it for at least 4 hours first. There’s a “charging station” that comes with this vacuum. All you need to do is very simple: attach the vacuum to the station and wait. 

Once it’s charged, simply pour water and hydrovac concentrate into the “clean solution tank”. The power button is on top of the handle. Do not remove the plastic cover from the brush roll (otherwise the vacuum won’t work).

There are 2 modes in total: hard floor mode and stain boos mode. They both worked great! They successfully removed messy stain on the floor. Also, the vacuum itself is not heavy to carry around. The noise is not loud either. Overall, it’s efficient, light and definitely can remove stains easily!
