It's not that big. Its about the height of a 2213. Just that it's squarish in design. You should consider it......since washing the canister will take place frequently. 2213 models don't have the valves to cut off the waterflow. I used to have one..always ended up with a wet floor during canister washing. Also must fill the canister manually after everytime i take it apart for cleaning...Furthermore, 2213 can't adjust the flow rate. 2226 can. Consider...
