I was extremely excited to use this product. I live in an apartment and was happy to have this. I like the sleek look of the product but I am very disappointed. The vacuum does not really clean in any sort of pattern. It's just random and when it hits furniture it does redirect itself but doesn't really come back to the area. It does run for about 45 minutes but it is loud so I can't really run it while doing work. I  like to use it in open spaces because it bumps into the furniture and just seems to repeat where it has already cleaned.
