What actually breaks during a handover
Not the cleaning. The reporting path breaks first: the contact who received hazard reports has gone and the replacement does not yet know they are the recipient. Then approvals stop, so a periodic item falls due and nobody can authorise it. Then access arrangements lapse, because after-hours registers and contractor lists are held by the outgoing agent and rebuilt slowly by the incoming one. Each of those is invisible for a few weeks and then produces a consequence somebody notices.
Each of those is invisible for a few weeks and then produces a visible consequence. A hazard that was reported three times to nobody. A carpet extraction that was skipped because no one approved it. A crew turned away because the contractor list was rebuilt without them. All of it is preventable by treating the handover as an event that requires action rather than as an administrative change elsewhere.
