HYLA is not big. It can move smoothly (much better than many vacuum cleaner). But you need to find a place to store the tubing.
However, it's very very noisy. You cannot use it as air cleaner when you are at home. Since I have a new born baby at home now, I will bring my baby to the house club while my husband use HYLA as vacuum cleaner.
