I use this for quick cleanings (mainly pet hair) in between main cleanings. The lightness and cordlessness make this a snap. The machine maneuvers well and collects dirt very well on floors and also well on my low-pile carpet. The battery easily lasts 2 cleanings of my 1800 sf space. Emptying the collector is easy. This is a single-button unit: there is only off and on. The beater runs all the time and has no manual height adjustment. I do find the need to clean the machine a bit more thoroughly fairly often, especially the beater bar; however, the relevant parts are easily accessible. It would be nice if the beater bar could be shut off for hard surfaces or adjusted for carpet pile. There are no hand controls (probably to keep the cost down). An attachment for cleaning non-floor surfaces would be nice.
