I've owned an 880 and 960 and these beater bars kept having to be replaced constantly. They are not "tangle free" as advertised. Something as minor as a long piece of string would rip up this bar leaving large gouges in the small flippers and eventually render then ineffective. And if a solid item got stuck, like a hair clip perhaps, the extractors would just keep spinning and rip up the flippers. The bristle brush would allow more space for larger debris to pass through. And the price?? For just one set of the extractors, is ridiculous. Nevertheless, for this reason alone, I prefer the late 600 and 700 series which still use the sturdier, effective and less expensive bristle bar and flexible brush. Sure I had to clean it once every 1-2 weeks but it only took a few minutes, or they were cheap enough to replace just once a month. These "tangle free" extractors had to be changed much more often along with the HEPA filter, another disaster. The HEPA filters for the 700 series are much much cheaper and just as effective. If Roomba could at least go back to using the bristle brush on the more advanced models, I'd definitely upgrade.

This model robot has been pretty durable and reliable. Although I'm pretty annoyed at how iRobot treats rollers like printer ink cartages - each newer model requires more replacements and more "subscription" income for iRobot. People are tearing up the internet complaining about the rollers on the new models, I feel fortunate I didn't "upgrade." This model's rollers have only required replacement once a year, although I do have to clean them carefully before every use. If my arthritis gets worse I will have to throw out all of my Roombas. This set of rollers I'm buying now looks identical to all my old ones I've been buying to years, fingers crossed.

I am on my 4th Roomba, growing along with each generation of models. I now have the Roomba 980, and am loving it. I have the GeoFence setup to start cleaning when I leave the house. I come home to a fully vacuumed quiet house, and a docked Roomba. More homes are leaning towards hard surfaced flooring (Wood, tile, and/or vinyl) not needing to be beaten. I would like to see the option of a brush style roller when purchasing new rollers.

These were better than the original. They seem to pick up more dirt than original rollers.

These work great, but if you have long hair beware, it will easily damage these rollers. The hair gets wrapped around the rollers and cuts through the rubber.

It seems to me that even though to original, 3 years old extractors were functional, the newer one do clean much better. I don;pt think that the decign changed, but that the older ones just wore down and the newer ones held a better vacuum.

5 dogs, 2 cats, large house. Need I say more? This is a life saver!!

Bob cleans from 12:00 am -3:30 am & the downstairs is always clean! We are considering purchasing another for the upstairs. We are perfectly content with Bob
