Stable income: Somewhat stable

Office cleaning as a side hustle can provide a moderately stable income for most people who try it. Based on online research and personal insights, many individuals consistently earn from office cleaning gigs, with some fluctuations depending on the number of clients and contracts. While it may not offer the same level of predictability as a traditional job, it can still serve as a reliable source of income. I'd rate it a 3 out of 5 because although there may be some variability in earnings, overall, office cleaning can provide a decent baseline income for those who pursue it.
