The Dreame L10s Ultra, L10s Ultra Gen 2, and L10s Ultra Gen 3 have very similar names, but that does not mean every replacement part is interchangeable.
Based on Dreame’s official accessory listings, some parts are clearly shared across all three generations, while others are separated between the original L10s Ultra and the newer Gen 2 and Gen 3 models.
The safest way to buy replacement parts is therefore to check the exact model generation and the official compatibility list for each individual accessory, rather than relying on a generic label such as “L10s Ultra compatible.”

Quick Compatibility Table
| Accessory | L10s Ultra | L10s Ultra Gen 2 | L10s Ultra Gen 3 | Official-Source Finding |
|---|---|---|---|---|
| Main brush | Supported | Supported | Supported | Shared across all three |
| TriCut brush | Supported | Supported | Supported | Official compatibility across all three |
| Mop pads | Supported | Supported | Supported | Shared official part available |
| Dustbin filter | Original-model listing | Gen 2/Gen 3 listing | Gen 2/Gen 3 listing | Gen 2 and Gen 3 shared; original model separated |
| Dust bag | Original 3L listing | 3.2L listing | 3.2L listing | Gen 2 and Gen 3 shared; original model separated |
| Side brush | Original-model part | Check exact listing | Separate Gen 3 listing exists | Generation-specific checking recommended |
The Main Brush Is Officially Shared Across All Three Models
The main brush is one of the clearest cases.
Dreame’s official accessory listings include the L10s Ultra, L10s Ultra Gen 2, and L10s Ultra Gen 3 in the compatibility list for the same replacement main brush.
That means an official replacement main brush listed for these three models can be treated as a shared part.
Verdict: L10s Ultra ↔ Gen 2 ↔ Gen 3 officially shared
This is also a useful reminder that a newer generation does not automatically require a completely different accessory.
The model generation matters, but compatibility has to be checked part by part.
The TriCut Brush Is Also Compatible With All Three
Dreame’s anti-tangle TriCut Brush is also officially listed as compatible with the original L10s Ultra, Gen 2, and Gen 3.
The TriCut brush is not simply another name for the standard main brush. It is an alternative brush design intended to reduce hair tangling.
For users considering a replacement or an anti-tangle upgrade, Dreame’s official compatibility information supports all three L10s Ultra generations.
Verdict: L10s Ultra ↔ Gen 2 ↔ Gen 3 officially compatible
Mop Pads Can Be Shared Across All Three Generations
Mop pads are another part for which an official shared accessory exists.
Dreame’s official listing for mop pad part number 20010100000872 includes:
- L10s Ultra
- L10s Ultra Gen 2
- L10s Ultra Gen 3
among its compatible models.
This means that, for this official mop pad, the three generations are explicitly listed together.
Verdict: L10s Ultra ↔ Gen 2 ↔ Gen 3 officially shared
When buying third-party mop pads, however, it is still worth checking that the seller explicitly lists your exact model.
A product that looks physically similar is not the same thing as an officially confirmed compatibility listing.
Filters Are Where the Generations Start to Split
The dustbin filter requires more caution.
Dreame has an official filter listing for the original L10s Ultra.
Separately, another official filter listing includes L10s Ultra Gen 2 and L10s Ultra Gen 3 together.
The original L10s Ultra is not included in that Gen 2/Gen 3 filter compatibility list.
That does not prove that an original-model filter is physically impossible to install in a later model.
It means something more specific:
Dreame’s official accessory listings do not currently confirm one filter as shared across all three generations.
For that reason, it would be misleading to treat every filter advertised as “L10s Ultra series compatible” as automatically interchangeable.
Verdict: Gen 2 ↔ Gen 3 officially shared; compatibility with the original L10s Ultra is not officially confirmed as the same part
For filters, always check the exact model names listed on the product you intend to buy.
Dust Bags Also Separate the Original L10s Ultra From Gen 2 and Gen 3
Dust bags show an even clearer generational distinction.
The original L10s Ultra has an official 3L dust bag listing.
Dreame’s later Gen 2 and Gen 3 documentation and accessory listings use a 3.2L dust bag, and an official dust bag product lists both Gen 2 and Gen 3 as compatible models.
So the safest interpretation of the current official information is:
L10s Ultra Gen 2 ↔ L10s Ultra Gen 3: shared official dust bag
Original L10s Ultra ↔ Gen 2/Gen 3: do not assume they use the same official dust bag
A marketplace listing that simply says “L10s Ultra dust bag” may therefore be too vague.
Check whether it specifically lists:
- L10s Ultra
- L10s Ultra Gen 2
- L10s Ultra Gen 3
and verify which generation you actually own.
Verdict: Gen 2 ↔ Gen 3 officially shared; original L10s Ultra should be checked separately
Be Especially Careful With Side Brushes
Side brushes should not be treated as universally interchangeable across the three generations.
Dreame offers an official side brush for the original L10s Ultra.
Gen 2 appears in separate official accessory compatibility listings, while Gen 3 has an official side-brush product that specifically includes L10s Ultra Gen 3.
Gen 3 also uses a newer extending side-brush design as part of its edge-cleaning system.
For that reason, the safest rule is simple:
Buy a side brush only when your exact L10s Ultra generation is listed as compatible.
This is especially important for Gen 3.
Verdict: Check exact generation; a separate official Gen 3 side-brush listing exists
What Should You Check for Each Model?
Dreame L10s Ultra
For the original L10s Ultra:
- A shared main brush is officially available.
- The TriCut brush is officially compatible.
- A shared mop pad is officially available.
- Use a filter listing that specifically includes the original L10s Ultra.
- Use a dust bag listing intended for the original L10s Ultra.
- Check for explicit L10s Ultra compatibility when buying a side brush.
Do not assume that a part labeled for Gen 2 or Gen 3 is automatically the same part.
Dreame L10s Ultra Gen 2
For Gen 2:
- The official main brush is shared with the original model and Gen 3.
- The TriCut brush is officially compatible.
- The official mop pad can be shared across all three generations.
- Gen 2 and Gen 3 share an official filter listing.
- Gen 2 and Gen 3 share an official 3.2L dust bag listing.
- Check that the side brush specifically lists L10s Ultra Gen 2.
Dreame L10s Ultra Gen 3
For Gen 3:
- The official main brush is shared across all three generations.
- The TriCut brush is officially compatible.
- The official mop pad can be shared across all three generations.
- The filter is officially grouped with Gen 2.
- The 3.2L dust bag is officially grouped with Gen 2.
- The side brush should be checked carefully because Gen 3 has a separate official listing and a newer extending side-brush design.
Why “L10s Ultra Compatible” Is Not Specific Enough
This is the main problem when shopping for replacement parts.
All three products contain the name L10s Ultra, but official accessory compatibility is not uniform.
The current official-source picture looks like this:
Main brush: shared across all three
TriCut brush: compatible across all three
Mop pads: shared official part available
Filter: Gen 2 and Gen 3 grouped together; original model separated
Dust bag: Gen 2 and Gen 3 grouped together; original model separated
Side brush: exact generation should be checked
That means a third-party replacement kit advertised as:
“Compatible with L10s Ultra / Gen 2 / Gen 3”
should not automatically be treated as fully verified.
Each included component may have a different compatibility range.
A kit could contain a mop pad that works across all three generations while including a filter or dust bag that does not have the same official compatibility coverage.
How Compatibility Is Classified on This Page
This page prioritizes Dreame’s official product pages, accessory listings, and official regional stores over generic marketplace claims.
The following terms are used deliberately.
Officially shared
One official accessory explicitly lists multiple target models as compatible.
Generation-specific check required
Official accessory listings differ by generation or a newer generation has a separately listed part.
Not officially confirmed as shared
Available official information does not support treating the parts as one interchangeable item across all models.
Importantly:
“Not officially confirmed as shared” does not mean “physically impossible to fit.”
It means the available manufacturer documentation does not provide enough evidence to make a broader compatibility claim.
When official evidence is incomplete, this page does not guess.
Regional Listings Can Differ
Some of the compatibility evidence used here comes from Dreame’s official stores in different regions.
Product numbers, packaging, accessory bundles, and even compatibility lists can vary by market.
Before ordering, check the actual product listing available in your country and confirm that your exact model appears in its compatibility list.
This is especially important when buying from third-party marketplaces or importing replacement parts from another region.
