perfect fit for the L40 Ultra
Color: L40 Ultra Accessories
I'm very pleased with this accessories kit. All the included items work perfectly with the L40, and are good quality, fit correctly, and cause zero issues. They install just as the OEM items do, and the L40 works exactly the way it did when it came out of the box. I was particularly pleased that even though it's a replacement, it came with another little screwdriver, as I'd misplaced the original.
These hepa filters fit snugly, stay in place, and work to take up dust and trap it rather than just spread it around the house. The mop pads appear to be good quality and get the job done. I like how they attach - easy to put on and take off, just like the OEM, so I can clean them easily and use them for a little longer. The main brush is so close to identical that I can't really tell them apart, and they work as advertised - little wrapping and tangling, and they deal with dog and cat hair without a hitch.
In all, this is a good value for replacement components that work and are good quality. Recommended.

These Mop Pads Made My Hardwood Floors Shine Again!
Color: L40 Ultra Mop Pad, Color: L40 Ultra Mop Pad
I picked up this 8‑pack of mop pads for my Dreame X40 Ultra, and they’re exactly what I needed. These attach with Velcro, so swapping them out is as simple as pulling off the old pad and pressing on the new one. No tools, no fuss.
My original pads lasted a long time, but nothing beats the feeling of putting on fresh, fluffy mop pads and watching the robot make the floors shine again. These are the same size, same fit, same performance as the originals.
🧹 Compatibility
Dreame and MOVA are basically sister companies, so these pads don’t just fit the X40 Ultra — they also work with a ton of other models, including:
- L40 Ultra
- X40 Ultra
- X50 Ultra
- L50 Ultra
- L10S Ultra
- L10S Pro Ultra Heat
- L10S Ultra Gen2
- L40S Ultra
- X30 Ultra
- L10 Ultra
- And yes — MOVA models like the E40 Ultra
If you’ve got a Dreame or MOVA robot, chances are these pads will fit perfectly.
🪵 Cleaning Performance
These pads leave my hardwood floors looking clean and streak‑free. The robot spins them with enough pressure to lift dirt, dust, and whatever the dogs track in. Fresh pads always make a difference, and this pack gives you plenty of backups.
💰 Value
Eight pads at this price is a steal. OEM pads cost way more, and these perform just as well. Great fit, great quality, great results.
⭐ Final Thoughts
Easy to install, perfect compatibility, and they make my floors look amazing. Couldn’t be happier with the purchase. I’ll definitely keep a pack of these on hand.

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.
