It is my opinion that virtually none of the small plug in UPS systems marketed today do anything to clean up the power. They are virtually all 'off line' UPS. About all they do is add some surge suppression that you can get from a plug strip.
Good point.
Although at 1500VA, it isn't so small for domestic back-up. It is probably a free-standing unit and, given that it is from a commercial organisation, a bank, it may be double conversion.
Sometimes we supply a UPS as part of a system. I don't recall any that were not true on-line systems. Sure, they are normally a bit bigger and mostly three-phase. But that last one we did, part of a lighting system, was just 1.5 kVA.

I personnel gave up on running my battery back up. However I don't do things at home that would be 'lost' without battery back up. Obviously if you are doing work that can be lost due to a power failure a UPS is a good idea, or you could just remember to hit 'Ctrl S' more often.
I use a laptop at home and at work.
A mains power interuption is a bit inconvenient in that peripherals stop working but data loss isn't a problem.
But, earlier this year I had my laptop stolen at an airport. Obviously I was a bit hacked off about it. Data loss wasn't such a big problem in that most of it was backed up on a server and most of my emails are copied to my PA.
What was annoying, and continues to be, is that my shortcuts and customisations were lost.
One click to get the phone directory - gone.
One to get the projects database - gone.
One for standard documents - gone
To name but a few.
