We had the v6 and it was ok but packed up after 6 months light use.
That's complete garbage. Anything that uses a bag will lose suction as it fills up, because the bag is the filter which clogs over time as there's less airflow due to the bag filling with dirt.
I wouldn’t go that far, just not fit for purpose. (y) 🏼
We have an air ram and it’s amazing. Its better than our old Dyson corded vacuum which we never use now.
