Polaris robotic cleaners

Sorry I’m advance for the long post...

I previously knew nothing about these cleaners until a couple weeks ago. I was given a Polaris 9300 sport. It had only one wheel working and after tearing it apart, I saw that it needed a motor for one of the wheels.
I found out pretty quickly that you can just buy a motor for one wheel and have to buy a whole motor assembly at $350. (Not going to happen)

I was able to find a unit for sale in my area for $150 that had no power supply so I took the risk that it worked, and worst case, I could make one out of the 2 of them.
It works great! (in my bathtub because I’m in Canada and my pool isn’t open)
So now I have a working machine and a parts machine!

Fast forward to the other day and a P93 came available at $120 and it had the symptoms of needing a new cord (which I have from my parts machine)
I replaced he cord and it works great!

Now for my question:
Which of these machines in better? I’m going to keep one and sell the other.
The P93 looks better (white vs the little bit fading blue)
Which one of these models was released first?
They are very similar, I have only seen a couple small differences in the 2.

Manual cleaning is better, you never miss a bit and it's quicker.

And all that stuff goes through your system and have to backwash... I like the convenience of a robot.

Didn’t mention manual cleaning in my post.. but “thanks” for your opinion

Hence my comment, I have owned pressure side cleaners, including a Polaris, electric bots like dolphin and aquabot and flapper cleaners.
Not to mention my customers cleaners.

Most disturb the water in their quest for the perfect clean, the fine silt is blasted back into solution. When you start cleaning the water is crystal clean, but after the water is not so sparkling as the silt has been stirred up back into solution. Yes leaves have been collected but not the fine stuff which settles back to the floor the following day. So the cycle continues, using more electricity and the expense of a pool cleaner, possibly a booster pump as well.

I use skimmer socks to stop the bigger stuff and cotton towelling catches the really fine stuff, so not much reaches the filter.

The reason dirt gets on to the pool floor is the skimming action is poor and pump runs too short.
I sold my cleaners and that was after timing how long the clean took including cleaning filter bags etc. Manual was cheaper, quicker, more thorough.
