Honestly curious, what kind of floors are you cleaning where you notice this, really deep carpets or something? I feel like the suction on my dyson v6 is perfectly adequate, better than any other cordless I've used and as good as an average bigger vacuum. We have mostly laminate floors and some really short carpets in the bedroom, and on either surface the dyson works well, pretty much gets everything visible after a single pass. I definitely don't feel a need to get a bigger vacuum for deeper cleans or anything.
