When looking for a vacuum to cover a large space it is recommended to look at either a commercial vacuum or a high-powered household vacuum. The important aspects to consider are the power of the engine as well as the size of the cleaning path.
Powerful vacuums can be found in both canister-based and upright models. Upright vacuums allow for quick mobility and easy maneuverability while the canister-based models have a larger storage for debris. Canister vacuums also tend to not have bags while some uprights do. This can play a role in the convenience and efficiency of a particular vacuum type.
