Kreepy found Dead in Pool

Mr. Krauley was found floating face up in the pool today. He was getting old and after several body transplants, he became too feeble to do his job anymore. If one year of a pool cleaner's life is like 7 years of a human's...he was at least 98 years old...

Now I want something that will do the job for me--quietly, efficiently and no sass. I have no objection to something simple or something new tech. I no longer try to impress my guests with the latest kitchen or pool gadgets, so something good but humble is fine too.

We have hopes of traveling now and then and want to empower our pool to take care of itself. Our pool pump automatically runs on a timer. Occasionally I'll have a neighbor check and make sure the water and salt level is O.K. We have a screened in pool area, so leaves are not an issue--dirt and sand are our foes..
What kind of pool cleaner can:
Operate without Supervison

Do a good job using existing suction port, returns and/or pump

Doesn't look funky...I want the pool to stand out--not a weird looking cleaner

Quiet, discreet...

Should I consider another Kreepy Krauley (now there is also a Kreepy Kruiser--anyone know the difference between those?)or one of those low pressure cleaners like the LETRO LEGEND II or a suction German engineered oneThe Pool Cleaner (I like how the word "Poolvergnuegen" rolls off my tongue...)

I guess a robotic cleaner means someone has to be around to put it into the pool and then take it out again, huh? I might want to be a bit of an absentee pool owner now and then...

Since my bedroom sliders are right by the pool....do any of these guys make obnoxious noises?

Thanks for any guidance oh pool gurus....I've learned so much on this forum and learned to 'relax' a bit with my pool. It no longer intimidates me like it used to....maybe the mojitos helped out with that...;)
