Exceptional Value – Identical Quality to OEM Parts!
Color: L40 Ultra Accessories, Color: L40 Ultra Accessories
I recently received this replacement accessories kit for my robot vacuum, and I couldn't be more impressed. To be honest, I was a bit skeptical at first—usually, when you buy third-party bundles, you expect some trade-off in material quality or fit, but that is absolutely not the case here.
Packaging & Delivery
The kit arrived exactly as described and was packaged very securely. Everything was organized neatly inside the box, ensuring that the side brushes weren't bent and the HEPA filters remained pristine during transit. It’s clear the manufacturer took care to make sure the product arrives in perfect condition.
Quality & Performance
After comparing these parts side-by-side with the original factory components, I genuinely cannot see any difference in quality.
• The Main Brushes: The rubber material feels durable and has the same flexibility as the original, picking up hair and debris without any issues.
• The Mop Pads: These are thick, absorbent, and the Velcro backing aligns perfectly with the vacuum’s mop plates.
• Filters & Bags: The HEPA filters fit snugly with a proper seal, which is crucial for maintaining suction power, and the dust bags are made of a thick, multi-layer material that feels very reliable.
Final Thoughts
This set is a fantastic value. Buying these components individually or from the name brand would easily cost double or triple the price. You get a massive supply of consumables that will likely last me over a year. If you are looking for a way to maintain your vacuum’s peak performance without overspending on "official" replacements, this is the kit to get. Everything snaps into place effortlessly and works perfectly.
Highly recommended!

Great Vacuum Kit
Color: L40 Ultra Accessories, Color: L40 Ultra Accessories
I'm not sure if I didn't read carefully enough, or if the title/description changed afterward, but I got this for our Dreame X50, which is similar to the X40 but not quite the same. It looks like everything in this kit will work with ours, except the rollers. The rest of it, the bags, the filters, and the brushes, look the same though, and I can confirm that the mop pads work. Overall, it looks like a great set, full of everything you'd need to freshen up the robot that keeps your house fresh.

Great replacement mop pads that hold up well through multiple washes
Color: L40 Ultra Mop Pad
I've been really happy with these replacement mop pads for my x30 Ultra Dreame robot vacuum. They snap on and off easily without any tools, which makes swapping them out between cleaning sessions quick and hassle-free. The microfiber material feels dense and absorbent — comparable to the original pads that came with the unit — and they do a solid job picking up grime on my hard floors, including tile and laminate.
Getting 8 pads in a pack is a great value. I rotate through them regularly and toss a few in the washing machine at a time, and so far they've held their shape and absorbency well after repeated washes. No fraying or velcro attachment issues yet.
My only minor complaint is that the fit can feel slightly less snug than the OEM pads, but once the robot is running, they stay in place fine and perform just as well. Overall, a solid third-party option that saves you money without sacrificing cleaning performance.

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.
