This is honestly one of the best purchases I've made. I have had mine for about one year and I've had no issues whatsoever with the quality of the product or it working every time. I think some things to note: this is not meant (in my opinion) for a whole house cleaning. I think a dry sweeper + wet mop or a cordless Shark + wet mop may work better, but for those sudden jobs, quick touch ups, or cleaning up after pets, this is exceptional. 

As an example, this vacuum can be used to clean up after my kittens, sucking up hair, any dust, and litter that inevitably gets tracked on the hardwood flooring. Then, I can do a quick mop at the same time. It's perfect! Plus, since anything vacuumed goes straight into the disposable pad, you never touch it and it never gets into the rest of a more expensive vacuum, where I wouldn't want kitty litter to be!
