My wife opened the box and used it Day 1. Said the assembly took like a minute since only 1-2 things to snap on and off she went. Loved being able to vacuum and steam our wood floors all at once and loved the way it all turned out. Made sure to show me how to clean and change the rollers as soon as I got home! I didn't realize it has a roller cleaner as part of the unit which is pretty neat! #sweepstakes
