OK so you are in the market for a new vacuum cleaner but you have no idea either to go bag less or not. I was in this same situation trust me it's a good question to dwell on especially when you have used bag vacuum cleaners in the past.
Each side has its pros and cons but let me just tell you right off the bat that bag less is the way to go hands down! I have used bag vacuums since who knows how long and after getting a bag less vacuum I will never go back to bags again. Bag less vacuums are so easy to operate and maneuver no more replacing bags when they are filled to the brim no more worrying where to throw out vacuum bags and better yet no more worrying where to buy vacuum bags yes that's right your worrying about finding a store that sells vacuum bags is gone when buying a bag less vacuum.
Also bag less vacuums store much more dirt than the bag vacuums which saves you constant trips when emptying the canister. Some positives about bag vacuums are that they are very cheap now a days and you can get them for a bargain because bag less vacuums are currently dominating the market. A negative toward bag less vacuums is that they are very expensive depending on the brand of vacuum of course but that's a whole other topic. Negatives toward bag vacuums are that they don't have the sucking and cleaning power that the bags less vacuums have.
Now that I have my bag less vacuum it is night and day when it comes to the amount of dirt my bag less vacuum picks up compared to how much dirt my bag vacuum picked up. The bags less vacuums have very strong brushes and very strong sucking power to really get that dirt that is sitting in your carpet. So this decision is entirely up to you but I have experienced first hand that bag less vacuums are much more superior in performance when comparing to bag vacuums. So if you don't mind dishing out more money in the very beginning for a bag less vacuum I would definitely suggest it. But if you cant afford a bag less vacuum up front that's fine to either one gets the job done. I just tend to lean toward bag less also because of the ease of operation when using bag less. Also no more wasting money on bags for the vacuums as well which can be a pain in the neck when your vacuum takes special bags that are hard to find.
