I bought this vacuum to replace my old Black and Decker (the older model). I thought the wall mount was the same, but it has changed it is necessary to re-drill the holes in the wall. The old model is reloaded alone, it was enough to put him in the wall mount. For this new model we must put the charging socket by hand (it takes a second) ... I thought it was a minus, but in fact it is more because like this, the craft Charging is not all the time but just automatically when one decides. The suction power is excellent, and the autonomy of the batteries. The only downside is that it is quite noisy in the treble ... to my ears to me ... but maybe I'm a little too sensitive of the sheet (lol)!
