Very nice device, simple installation and use, hold a charge well, and is very powerful for wireless. By cons, in what has been said about the battery time span, as are 3 speeds, the battery life time is determined as follows, mini, "up" 45 minutes, means " up "35 minutes and turbo," up "25 minutes. These times are given in the brochure and the "up" which means over, I have not checked yet I am in turbo mode serves all day, but to get to 25 minutes it takes the space. The downside is the battery charging time 10 hours, but it is not obliged to wait for the first day I got served without recharging and'm falling down, I put the camera charge and 2 hours after I was able to use it, so 10 hours is the maximum time to recharge. Beware of free carpets, as the brush is electric, fringes tangled in it. On the brochure, there has written two type of battery, a battery of 18 V and 24 V, it is of course the 24 V I, because for 18 V sounds less long time, remove 10 minutes at each speed.
I recommend this machine but not the packaging on which stuck my address, which means that it is on the packaging of the device that has stuck my address, it was not packed in a cardboard box for protection. Fortunately he arrived in perfect condition, thank you post.
