I tested the vacuum cleaner Philips FC6170 PowerPro Uno received for testing by Philips. FYI, I have an apartment of 84 sqm, tiled floors throughout except soil 3 bedrooms are parquet. I find it very efficient in terms of power. It slides perfectly and standing is very convenient. Regarding autonomy, no problem making the whole apartment. Question maneuverability, it goes very well under the chairs and table, even low. By cons, hard to suck in my buffet it accesses only the first ten centimeters.
Conclusion For me it is a very good vacuum cleaner for large surfaces, against lacks the handheld unit, which would make baseboards, corners of the ceiling, etc. Either you need a hand vac squeegee with complement, or see if the model below, the FC6168, which provides him with a hand vacuum is sufficient for large areas (in power and autonomy).
