I only use the bagless vacuum for 4 years. Their disadvantage remains even when the frequency with which you have to empty the dirt tank. The bags vacuums can store much more dust, but I was tired of changing bags (always) laborious and expensive. I have "fun" to clean my house with this Philips model (which I personally find very design), and the power blew me away compared to actual consumption. Before, we thought the aspiration of a aspi its wattage, but the situation changed now really. Noise still remains a bit too high for my taste.
