Love it, love it.... LOVE IT!!!!!!
It is over 3 years old and I still use it 1-3 times per week. It is exceptional on vinyl and hardwood floors, getting up dust & lint that is hard for me to get with a broom. The only maintenance I have had to do is replace the rechargeable battery, which I got at Amazon.com for under $40.
You do need to keep the brush clean and check the filter, but the maintenance is minimal.
If mine dies, I will replace it immediately. It saves me lots of time and effort with my big sweeper.
