i was sweeping our hardwood floors daily so my husband bought me this roomba....i love it!  just push a button and it does all the work.  the only issue i had was when it would go into our kitchen and get stick under the counters.  i simply placed the virtual wall in my kitchen and problem solved!  it does a fantastic job (better than i could with a broom and dustpan).  when it is finished, it even goes back to the docking station.  i simply empty the contents at the end of every day.  i am able to program it to clean when i am away if i deisre.  can't say enough about this vacuum.
