A good time to clean your shower sump pump, is while your better half is in the shower. Why then? Well, with fresh shower water running into the sump, it will help flush away any soap scum and debris as you do the following.

Remove four screws holding on the lid. The lid easily lifts off. Grab an old toothbrush - not your wife's - I was just kidding - don't even think about it - and do a gentle scrub inside the plastic sump well. See the soap scum build up? It will just pump overboard as you scrub.

You get to visually ensure the float switch and pump are working well, and inspect for clogs. The plastic filter is easily removed, and can be scrubbed out, removing hair or debris. I also used a piece of paper towel pushed inside the filter with the toothbrush, and cleaned it vigorously under hot running water.

After a shower, pour a little Mr Clean or Lysol lemon fresh disinfectant down the shower drain. It will help prevent soap scum buildup in the standing water, because the pump never completely empties the sump well. The yellow colour is a little Mr Clean. It also prevents any stale water odors from that sump.

Now, your spouse is happy and so is your shower sump. Oh, and don't accidentally put that toothbrush back in the washroom, but keep it in your toolbox for other small jobs.
