Thanks man! What do you think about the Hepa filters in Roomba robot vacuums?

  As far as I can see, they have dust reemission class B in EU, which means they are OK, but probably leak some particles. It's understandable. On a small machine with little power, if they put a better filter (more resistance) the vacuum is not going to have much suction.
