I've had this for about 6 months now.
As described it has 2 brushes that pick up the dirt etc. and as they carry on rolling the dirt is deposited in the containers fore and aft.
Very light to handle, easy to lift using one hand. Because of the light weight it does feels quite flimsy.
Unfortunately one brush is a spiral arrangement of bristles and just doesn't pick up nearly as well as the other brush which just has the bristles in a circular arrangement. You end up emptying the cleaner when one container is full to the limits and find the other one is still half empty (because the spaniel dog hairs etc. have wound around the spiral brush).
My mother has the smaller Bissell Sturdy Sweep, which only has one roller brush, and this picks up dirt better and has larger dirt containers so doesn't need to be emptied as often. The Natural sweep, in spite of being larger and costing more, actually holds less than its smaller sibling because 2 brushes take up room that could have been used for larger dirt containers.
I'm hoping that this breaks soon so I can justify buying a new different one! Even though it feels quite flimsy it has survived being slammed around quite roughly so the build quality must be reasonable!
I've only given it a generous 3 stars because one half of it works well and would get 5 stars but the spiral brush half only gets 1 star. 2 and a half would be my real rating.
