The answer to 'vacuum water damage' is that vacuuming up standing water or excess moisture from a water damage incident is generally not recommended. Trying to vacuum up water can damage the vacuum cleaner and potentially spread the water to other areas.
Instead, the proper steps for dealing with water damage are to first stop the source of the water, then use absorbent materials like towels or mops to soak up as much of the standing water as possible. Dehumidifiers, fans, and air movers should then be used to dry out the affected area. If the water damage is extensive or the area cannot be fully dried within 24-48 hours, it's best to call in a professional water damage restoration company to properly assess and remediate the situation.
