How does the 770's suction compare to the 650?

also interested in this.
for some reason the 700 series has passed me by, as you can pick up 600s for next to nothing and the 800s (i've found) are a big step forward from the 600s. The 700s always felt like a bit of a no-man's land to me, and aren't much cheaper than the 800s. Is there a good reason to consider them?

I have 665 and 805.
As the 7xx is the last brush model and as the brush seems to work better for short pet hair on our area rugs, I am interested in any improvements over the 6xx series.
(Would only buy a cheap used one)

I have 2 800 series robots and a 960 on it's way, I briefly tried a Neato D7 and the brush was the #1 reason I returned it. Unless you wanna spend a ton of time cleaning those brushes I would avoid them. The rubber brushes on the 800 and up are by far a better design IMO.

From the sparse reviews available, it appears the 770 shares many of the Roomba 805's smarter AI, navigation system and advanced wall sensing capabilities.

I have no problems with brush hair and would like to see a comparison of suction.

Im not a fan of the 2 small hepa filters on the 7xx. I prefer the 6xx bin. I reckon the hepa filters restrict air flow too much. Hence on this forum people have been trying to hack the filter to improve suck.
