My advice is to agree to a schedule.

In our house we have the following:

“Clean 15”: after every meal, everyone takes 15 minutes to do as much clean up as possible in the kitchen and dining room. If there’s time left, you can tidy up elsewhere, do some dusting, whatever.

“Dirty 30” every other day, everyone does a half hour tidy up in the main areas of the house. Some reduce clutter, others may clean a bathroom. It doesn’t really matter what the specific job is, but it should take a focused effort of about 30 minutes.

“Hour of power” once a week. Everyone commits a full hour to housework. Whatever needs it the most, gets done.

The key rules are:

1. Everyone in the house participates at the same time.

2. Everyone gets as much done as they can in the time specified. No slacking.

3. At the end of the allotted time, everyone stops. - even if there is more that can be done, it can wait for the next dirty thirty.
