We bought this vacuum there just 3 months. After a good first impression of power and silence, we quickly became disillusioned by seeing how fast the filters clog. We have 3 kids, no pets, we pass the vacuum cleaner about once a week and sadly at each pass, the power decreases drastically when the apartment is not fully cleaned. We must empty the tank during passage if the hair a bit long of our girls blocking suction. It should also wash (and let dry filters for several hours) after each pass or you risk nothing ... suck the following week (following the procedure which is quite well explained in the user guide, this is no problem)
In short we are very disappointed. After reading many very positive feedback, we are stuck with a vacuum cleaner that sucks very well indeed, but only when it is perfectly clean. If it must be washed fully with each use, what mess of time and water!
