Original equipment quality
Color: L40 Ultra Accessories
Perfect set. I held back on this review until I had to chance to try everything, and it is "OEM" quality in every way. The mop heads fit securely and are the right size and texture. The filters are exactly right and appear to be high quality materials and snug up properly. The rollers fit correctly and last as long as the originals. The brushes appear to be the same thing. Finally, the bags themselves fit well and snap shut for disposal. I would be hard pressed to tell the difference, and moreover the cost difference from original is extreme (4X or more). I'm ordering another set.

Good value bundle, everything you need
Color: L40 Ultra Accessories
I got this accessories kit for my robot vacuum and it’s actually really convenient to have everything in one pack. Instead of ordering parts separately, this includes pretty much all the main things you’ll need over time — brushes, mop pads, filters, and dust bags. The pieces fit well and are compatible with the machine as expected. Installation is simple — everything swaps out easily just like the original parts, so no issues there. Kits like this typically include the same core parts (main brush, side brushes, filters, mop pads, dust bags), which are meant to be replaced regularly to keep the vacuum working efficiently. The quality is decent overall. The mop pads absorb well and clean effectively, and the brushes pick up dirt without any problems. It may not feel exactly like the original brand parts, but for the price, it does the job. What I like most is the quantity — having multiple replacements means you don’t have to think about buying more anytime soon. It’s especially useful if you run the vacuum often.

OEM Quality at a fraction of the cost
Color: L40 Ultra Accessories, Color: L40 Ultra Accessories
I have a Dreame x50(Main floor)and a Dreame x40(Top Floor), for over a year now. I use them each 3x/week in mainly mopping downstairs(vacuuming area rugs & floor) and mainly vacuuming upstairs(carpet) and some mopping(2 bathrooms and one bedroom); so I know a little bit about accessories and what they can and cannot do. Even though these are for the Dreame x40, some of the parts fit both the x40 & x50 perfectly. As the 1st pic shows, the mop pads, corner brush, and dust bags fit perfectly on both. However the main brush, and filter insert are different. But these all fit in the x40. The only slight problem, as I pointed out in other reviews, these new filter cartridges are dark gray, not white, so can’t see the dirt as much, when cleaning them. They easily slip in and feel sturdy as the OEM. The product on left of each pic is the OEM, right is this product. The quality and design is the same as the OEM, and far less expensive. I recommend these if you own either machine.

Asurion Plan is a Must
This protection plan is definitely worth it. I returned my car vacuum after having it one year because it was not holding a charge. I received a email with a gift card the following day. So I purchased another one. And I also purchased the product protection plan.
