When I hoover our bedroom I get nearly a full hoover each time. It doesn’t matter how often I hoover. I used the carpet cleaner to wash the carpets this week and hoovered the day after and still got nearly a full cylinder.
We have a cat but a lot of it is dirt/ fluff not cat fur. I have 3 different hoovers and same result with them all. Carpets are around 2 years old and no shoes upstairs so can’t see where all the dirt is coming from?
