A hot reaction recoilless to judge the reliability of the product over the long term (including the life of the battery). Bluffing, nothing to do with the classic small handhelds. The suction power is much greater. Tested particular on the couch squatted by my angora cat in full moult, nickel result. If empty the tank simply by opening the bottom, it falls directly into the trash without having to put your hands. With its nice look, I feel I'm being trigger-happy!
