It means your roomba is efficient, value for money! I mop the floor everyday, and yet the tribolite that I've received for only 2 weeks, is almost full already. Now I worry about the cost of changing the filter, makes me want to switch to a roomba instead.
BTW,mosmos, thanks for ur tip, I got my 10 percent from IRobot, but they're taking a long time, took them 2 days to ship from warehouse, and I've been waiting for the last 9 days since, still no news from vpost.
