The suction is great - haven't even needed to use the maximum power yet. My old hoover wouldn't vacuum all the hairs and fluff on carpets whereas this one does very easily, so my carpets are finally looking brand new again! This also doesn't scratch my wooden floors which my old one did which is another plus! The battery life isn't super long so wouldn't recommend for a huge house but for a smaller hourse or flat it is ideal (also doesn't take up much storage space)
