Can you leave pool vacuum overnight?

No, you should not leave a pool vacuum running overnight. There are a few reasons why this is not a good idea.

First, leaving the vacuum running overnight could damage the pool pump. The pump is designed to run for short periods of time, and running it continuously for an extended period of time can cause it to overheat and fail.

Second, leaving the vacuum running overnight could also damage the pool liner. The vacuum cleaner's wheels and brushes can scrape the liner, causing it to tear or leak.

Finally, leaving the vacuum running overnight could be a safety hazard. If someone accidentally falls into the pool while the vacuum is running, they could be caught in the vacuum's suction hose and injured.

For these reasons, it is important to turn off the pool vacuum when you are finished using it. If you need to vacuum the pool for an extended period of time, you should do it in multiple shorter sessions, rather than leaving the vacuum running overnight.
