I believe that this cordless vacuum stick is much better than others, but battery life still not the great.I have bought it for my car cleaning, but one fully charged battery was not enough on low level of suction. I needed to charge the battery on more time.
Overall is very nice design and brilliant filtration of Hepa filter.I like that the main brush head has a motor, but it of course use a power.
If you want to clean a small areas of surface it is the good choice. I recommend :)
