Pros are quite effective picking up dirt. Can be used for hard and carpeted floor. I could vacuum 3-4 rooms without having to recharge. I like that it had a switch on off instead of having to press the trigger all the time causing pain of finger and thumb.
It is quite quiet too and reasonable price.
Cons are it is heavier than expected. Due to weight of battery. Battery can fall out spontaneously.
Well time will tell how effective it is medium to long term.
