Upright vacuums are not better than canister vacuums. They both have their pros and cons, and it is up to individual preference which type is better for your home. An upright vacuum cleaner is great for thick carpets because the weight of the vacuum adds to the cleaning power. However, upright vacuums can be more difficult to maneuver and steer, and depending on the design, they may not fit under low-built furniture. A canister vacuum is easy to maneuver, and it fits under furniture and appliances. Still, the cleaning performance is not quite as good when it comes to very challenging surfaces like thick and dense carpets.
