Yes i have a 581 and 880 too and it is great, added a Thinking Cleaner Wifi module that actually does more than the 980 does unfortunately only available for 5xx and 6xx models,... wish there was one for the 880 because that would have made it complete for me... The 880 is cleaning the best the 581 is more for…

Hell, $650 doesn’t sound worth it either when you can just do what we do instead. Never vacuum.

I have the 880, it is fantastic and picking up the fine dirt and tons of cat hair we have in our home on all our hardwood floors. The $675 price tag was daunting at first (Now $650 on Amazon), but has been well worth it.
