Little maintenance is necessary for pond vacuums but they benefit from being stored in a clean and dry condition, including the debris basket.

Hand pumps may need their valves replaced at intervals so look out for service kits.

Powered pumps are not used as often as filter pumps so they don't need the same care, and any fault and subsequent delay in repair is not so critical. However, it's still important that electrical connections and cables are checked before each use.
