Finally, a vacuum cleaner with decent suction power! The installation of the battery pack was not as bad as many claim here ... The charging time is relatively long, but also makes the device but not directly limp as other brands. The detachable front with filter is very well resolved. The sucker can suck both dry and wet. The only major drawback is that it from the suction port everything blows left and right! This is particularly annoying when you want to clean a slightly larger area - since half flies gone for :-( why only 3 stars from me. Who can act that - a very strong buy recommendation due to the power!
