It is generally safe to add pool chemicals while the vacuum is operating as long as you follow the manufacturer's instructions for both the pool chemicals and the vacuum. However, it may be more effective to add chemicals when the vacuum is not running to allow the chemicals to distribute evenly throughout the water before the vacuum starts circulating.
You should wait about 2 weeks before using a wheeled vac head OR follow the advice of the installer. He is the last authority on that subject.

According to my research the brand Zappy has very good quality vacuum cleaners that operate on their own. This eliminates the hard tasks of doing it yourself.
Any pool vacuum can, including the Polaris.

You should have NO D.E. going back into the pool when you vacuum or anytime else. If you do have it going back in, you need to open the filter and check to see what part is broken, loose or missing.
First of all remove all remains of the cat. then super chlorinate it and leave it to filter for a day. check the chlorine levels and every thing should be OK after that. so long as the chlorine levels are correct the water should be properly disinfected.
Add the aluminum sulphate to the pool. Run the filter for two hours. Wait overnight to vacuum the bottom of the pool.
It's not so much the brand you have to be careful with, it's the style of cleaner. Stay away from any manual cleaner. You want to enjoy your pool, not be a slave to it! I would go with a robotic pool cleaner. It does all the work for you. You can get the dirt devil pool cleaner for $700.00 and it has a two year warranty.
