In case you're interested, Ryobi sells dual roller power head separately.

Thank you for the video... I have a question. If you use it on a hardwood floor, will the vacuum cleaner brush keep spinning and scratch the floor?

How is that Ryobi holding up? I’m thinking about getting a non brushless version but I’m not 100% sure.

For some of the Dyson range you can get an aftermarket adapter to use Ryobi batteries with it. It's all swings and roundabouts though. It's going to be handy if you want a quick change battery setup on the Dyson, but it's unknown if there's a chance you'd overheat the vacuums electronics if you were to run a few 5Ah Ryobi batteries through it back to back on the Max setting. Ryobi batteries aren't particularly cheap, but if you use Ryobi power tools, you're already going to have batteries and a charger kicking about. The adapters can cost as much as an aftermarket Dyson comparable battery, but again, if you're already using One+ batteries you'll not have to buy another dedicated Dyson battery. Aftermarket Dyson batteries tend to be questionable quality (For every well made one on the market, there's at least another that's over advertising the capacity and using old recycled laptop cells), but there's a fairly good chance that even a cheep aftermarket Ryobi lithium pack will outperform the stock Dyson battery. The Ryobi packs will slightly under volt the Dyson cleaner, but apparently not enough to cause any noticeable change in suction. So as you see, it's plus and minus's all round, but it's at least handy to know that these adapters exist purely in case they'd fit better for your particular use case. They're also available for a few other cordless tool batteries too for folks who've bought into something else, like the Makita or Milwaukie range.
