I purchased this vacuum/wet mop because I needed a high quality, powerful, lightweight cleaning solution that would allow me to keep up with floor cleaning without exacerbating the pain from 3 spinal injuries and be easy to use when my movement disorder flares. It has been a great purchase.  The only thing I wish it had was a way to turn the brush roller off for use on hardwood and tile surfaces.  It can push heavier debris out of the back cleaning head if its not centered near the intake.  Would I purchase it again?  Absolutely.  Doubt I will ever need to.
