I know this is old
I saw this thread earlier today that I didn't even knew it existed so I thought I would share my own opinions on these Optiflows. I've used all the Optiflow models before at my old vacuum store when these were out in like the late 2000's. I actually liked the silver MC-UG775 model the best than the green MC-UG787 model because I find it cleans carpets a little better than the green model with a steel bottom plate and a 3-row steel brushroll. The blue MC-UG773 and the Ultra-Pro model cleans just about the same as the silver one because all three use the same design but the silver model offered a switch on the handle than on the body, it has a vac gauge light, and it has a switch to turn the brushroll off than the other two.
I see some members were wondering how these competed against like Miele, Kenmore, Kirby, or a tandem air vacuum. Well I've used all of them before so here's what I thought;
Panasonic vs Miele: vegassucks said before they were both equal, I will have to agree because they both perform very well. But I perfer the Panasonic because it's a little more simple to use.
Panasonic vs Kenmore intuition: Oh definitely the Panasonic was way much better because it does better on carpets, it's more quiet, and I can feel the Panasonic was more durable. Plus the parts are also much cheaper to get than the Kenmore.
Panasonic vs Kirby: The Kirby is way much better on carpets but using the hose on the Panasonic was much more easier but it doesn't have enough airflow like the Kirby.
Panasonic vs Tandem Air Riccar/Simplicity: The tandem air machines does WAY better on carpets but I like using the hose better on the Panasonic.
But overall they were the most expensive Panasonics I have ever seen because they were sold between $500-$900. But I think they were the best models that Panasonic has ever made. So yeah that's my overall thoughts on these, if anybody asks what is the best Panasonic I have ever used, I would say the silver MC-UG775 was the best one I have ever used.
