AJ,
I can explain what happened. First of all the vacume cleaner eats most likely about 12amps all by itself, when the cleaning lady plugged it into the UPS it most likely tripped its circuit breaker. At that point the UPS would go to battery power, but still couldn't supply enough power for the vacume (which has a much more "agressive" power supply than a computer does) cleaner and the computer equipment and simply shutdown due to an overload. The UPS doesn't know what "electically" is connected to it, so it tries to power everything connected to it.

Some ideas, buy a bigger UPS so that you can have her vacume even if the power fails, or tell the cleaning staff to stay away from sensitive electronic equipment. Another idea is to buy some of those cheap plastic plug inserts that make outlets childproof so that no one else can plug devices into a mission critical UPS device.

Any UPS product would have had the same problem.

BTW - other devices to watch out for, or "Power Monsters" as they can also be known as are:
Microwaves, Quartz foot type heaters, and any big device like vacume cleaners. (should never be plugged into a UPS).

Don't get mad at the product, and I am sure that the cleaning lady didn't do it on purpose.

Steve...
