Lots of companies make soft rollers, and as you would assume, they vary from brand to brand. A lot of bias and unproven criticisms of soft rollers float around on here, but the idea is not bad. In fact, many of the well-designed ones are excellent for dusting fine dust and debris off floors, which was their intended purpose. With companies such as Samsung, LG, Dyson, and so forth, they put their soft rollers through rigorous testing to ensure that they do not damage floors or scatter debris. If they really did scratch hard floors and scatter debris to any significant degree, we would certainly be able to source reviews of folks complaining about that, but that has not been the case. There is not some "marketing" conspiracy; they are popular because they are nice attachments to have and they work for their intended purpose. It is not that complicated. I guess if you are sucking razor blades, sand paper, thumb tacks, and so forth into your soft roller, you may scratch your floors. Likewise, if you have delicate flooring, just be mindful of what you use on them period. In any normal environment, a competently designed soft roller is far from a damaging tool for carpet. I have even seen the user on this post who said that soft rollers damage hard floors make a video advocating for a soft roller, but that was just because it was from a brand that he likes. Despite my lack of hate for soft rollers, I dislike the Shark DuoClean designs for a couple reasons. First of all, they tend to break easily. A lot of them have issues with the front rollers not spinning due to the pulley coming loose on top of other issues. Also, although it is nice to not have to change between a carpet head and a hard floor head, the head itself is does not have the "floating" design of some of the more premium hard floor rollers. They are safe on most floors, but I would be careful with delicate flooring and large debris, as that could be an issue. They are not as delicate on flooring as some better and more expensive brands. You should definitely look at the LG CordZero A9 Ultimate , which is better than the Dyson in many ways. For example, every part of the bin can be washed down to the cyclones. It also comes with a charging stand that can be configured in numerous ways, two batteries, a miniature power nozzle, a carpet/universal nozzle, obviously the soft roller, a telescoping wand, and onward. It is one of the more powerful cordless vacuum cleaners on the market and honestly one of the better deals out there. You can look elsewhere for their various models, just make sure you get one with the attachments that you want. I know Costco often has good deals on them. I hope I provided some realistic insight into the world of soft rollers! Answer from JohnnyHucky on reddit.com
