Hot tub maintenance between guests?

Hello, My wife and I have a hot tub at our vacation home. We often rent to guests and are not able to be there between guest stays. We have a maid service to take of the house, but they don’t do hot tubs. Anyone here have a solution that works for them? Posting because we just had a guest complain about our hot tub not looking like it was ready for use. Thanks for you replies.

@fishtayl We have a pool and spa maintenance crew that comes once a week to take of chemicals etc. We also have our house keepers, check on the spa, to make sure its not in disrepair after the guests check out.
