A popular vacuum configuration these days is the bagless vacuum. I love it since I save money by not using these vacuum bags. All the dirt goes into a canister and you empty it out as needed. One item that some may overlook is the filter. In my vacuum, there are two filters. One is a Hepa-filter located beside the canister and the other is a located on the side. I make it a point to clean this out everytime I empty the canister. If you find that the suction is not that good, you might want to check out your vacuum filters and replace it if needed.
