This robot vacuum is pretty low tech, but does a relatively good job.  If there is a room you don't want it in, you'll need to watch it carefully or ensure that you have a barrier in place to keep it out.  It is quieter than a standard vacuum cleaner, but is far from silent.  The chamber is big enough to collect dust for a few days, and it doesn't take too long to charge.  Overall,  it helps manage dust and debris, but you do need to keep an eye on it to keep it away from high pile or fragile rugs.
