My ShopVac Vac N Vac is the vacuum that I chose because I can use it for wet and dry and it has two different size canisters,the large canister has casters to make it easier to move from one place to another I use the Vac N Vac as a regular vacuum cleaner it is slightly inconvenient to not have a regular vacuum but the power of the ShopVac is great and it cleans up any mess that my family can make.  Until I bought this vacuum I have never had a vacuum that has had enough suction power for me and this is something that all ShopVacs have.  And having a second canister that is larger all I have...
