Vacuumer sled is and will remain the star vacuum cleaner thanks to Philips. It's always difficult to choose a brand but with Philips is a quality assured gag over several years. This vacuum Performer Expert is class A, with Max Airflow technology for maximizing airflow, a large capacity bag, TriActive Max brush all floors and a HEPA filter 13 for cleaner air in less than allergies. To summarize, a beast of competition combines efficiency and longevity. It is effective on all soils, it tracks down the dust in every corner with incredible suction power and ended allergies with its high level of filtration. It is handy, lightweight and low power consumption. The only negative point: it is a bit noisy when the servo amplifier is at its maximum. I highly recommend it.
