Well one of the main issues with the fluval canister is that they use the ribbed tubing which is prime location for gunk to accumulate. The gunk is held in place when the filter is continually running but once the flow stops, it loosens so when the the filter is turned back on, the loosened stuff shoots into your tank. It is very annoying to clean with a pipe cleaner, even after spending hours on it, there will still be gunk flying out of the outflow. This is one of the major design flaws with the fluval '05 systems. However, the benefits of the tubing allow it to avoid kinks and the flow through it is smoother than with normal tubing.
Restarting the filter with the outflow in a bucket is an idea, but then you would be trying to fit a bucket into your tank and then having to life it out, or detaching the tubing from the tank, in which you might as well just do a full clean on it.
