The hoover battery is fine, lightweight. 
However it is not good if you have pet fur or long hair as every time I use it I have to cut the hair out which takes away the convenience. I know it is not anti hair wrap however I have a shark which isn't anti hair wrap and only have to remove the hair about once a month and it's only my long human hair not pet hair, this Samsung vacuum almost wraps every bit of hair around it every time.
