I give this three stars. It's powerful and useful. But, you'll be lucky to find spare filters for it easily. I can only find one seller on amazon that has them in stock and the cost of the filter with p&p is almost as much as the machine itself!! To empty this machine you need gloves because all the muck sticks to the filter and does not lie at the other end of the dust container as with other makes. All this is not good for a machine that is powerful and capable of good suction! If you could get the spares more easily then this would indeed be a bargain at the price inc p&p.
