Very efficient, easy to use.
Replacement for my old S8 cat n dog hoover , does a good job picking up the pile on my old carpets, not much resistance pushing forward pulling backwards just enough to let you know the roller is biting. My hoover is one of the last 2200 watt versions , I rushed out and bought it dis punted from a curry store when the government announced the EU were reducing motors to 1600 watts, in 2014 , then down to 900 watts in 2017 , so mine is 12 years old used a few times a week still very strong , so toes it works the roller very well
