I am using the vacuum for about 2 weeks. .. and Im very disappointed. The running time to clean about 240 sf on wooden floor with 2 small area rugs is about 40 minutes. Recharge takes 1.5 hr.... Getting stuck all the time on literally nothing. It can get behind the furniture, but can't get out. ... or get stuck between chair legs or even when trying to get on area rug (which is not tall at all - short short hair) The corner brush is a joke - it is so soft and flexible that doesn't do the job. I used the vacuum about 4 -5 times and I can throw the brush away. I use to have 500 series and this was much better . I was expecting probably more for newer and more expensive model. I Do not recommend this product.
