I can speak only for this unit. As Philips has re-established a great household helper. The cyclone technology works very well. The level is clearly visible through the Plexiglas container. Due to the strong suction force, it is necessary to reduce the engine speed by means of rotary knob, if you can push the nozzle is very difficult on the carpet (according to Operating Instructions). This is with me almost on the lowest speed and yet sucking tidy. It's also nice that the connecting cable is longer than with other models and thus the radius of action is increased. To remove the collecting container it is necessary this ertsmal of the machine (above) wegzukippen before you can lift it out then. Unfortunately is not in the description, for a while took me the rauszukriegen. The container then I clean after tipping a long brush (also not included). Not attached to the container the foam filter in cleaning forget these can be easily tapped. I can only recommend this sucker.
