how about a central vacuum
If you want a powerful hose cleaner, nothing beats a central vacuum, and you don't have to have pipes to use them. Some central vacuum units have a utility valve built in and for those that don't, you can simply attach a utility valve to the in-take. If you get an electric central vacuum hose you can use any power nozzle you want. This set up is more powerful than any portable canister cleaner. As far as I know, the most powerful single motor central vacuum unit is the Drainvac Viper, I have this unit and it's awesome.
