I use the cordless hand vacuum cleaner now since about 3 weeks, mainly for the absorption of cat litter and cat hair. With the suction I am very satisfied (he also has 18 V). Charging the battery is very fast, because the sucker though often but always is short in use. This seems for the lithium-ion battery - unlike the NiMH batteries - to be a problem. The cleaning of the teat is easy when you, apart from the electrostatic charge, by the fine dust from sticking to the housing times. Some minor drawbacks there are: The price is very high, the sucker is not very quiet and the air is so strong that this fluff are whirled and my two cats flee. From my perspective, the sucker is nevertheless highly recommended. If he should have a lifespan of more than one year nor now, then I'm satisfied.
