With my old vac I had to empty it every 2-4 vacs, the new one we will have to wait & see

Lime & Berenice - We got a Kirby 2 weeks ago. It's sooo good. We told the sales guy he'd have to throw in some extra bags & the heavy traffic spray. So I think we have 3 or 4 spare bags, but the bags arent that expensive from them anyway seeing how long they last before needing to be changed
