So very disappointed with this Numatic . I bought it as we've got a lot of dust at the moment with our building works. Sadly it's not coping at all. Just over a week and the red button keeps coming on. I've changed the bag despite it not being full, checked for blockages in the hose, checked the HEPA filter and that's also fine . I was wanting to use this on a daily basis but it doesn't cope at all.
Arrived quickly. Very well priced
