Just ordered a Dolphin DX5. Waiting for it to come.

I've read the manual online, and it states:

"To prolong Wonder brushes or combined brushes longevity, it is recommended that they be kept wet at all times even when stored for a long period of time."

I was wondering what the best way to do that would be.

I'm in the Pacific Northwest, and we have a fairly short swimming season (about June to early September).

I assume I wouldn't want to actually keep it in the pool during the off-season just to keep the brushes wet.

Also, is there any problems operating it with the solar cover on? (Other than the fact that whenever I remove the solar cover, it dumps a bunch of debris in the pool)
