Roborock Dyad vs. Dreame H11 Max

Roborock Dyad vs Dreame H11 Max

I’ve been testing wet/dry cordless vacuums over the past month, and we’ll look at them in this comparison.

The Dreame H11 Max and Roborock Dyad are the first cordless wet/dry vacuums or hard floor washers I’ve tested, and the results have been positive.

But which option is better? I’ve put each through a grueling series of tests on various messes to find out.

Self-Standing without the Base: Dreame H11 Max

  • Self-standing even without the charging base
  • Large, easy to read LED screen
  • The open dirty water tank design is easy to clean
  • Decent run time of over 40 minutes
  • Ergonomic handle controls


  • It doesn’t turn as sharply as the Roborock Dyad
  • It needs more passes to clean dried stains
  • More expensive than Roborock

Dreame’s design is more traditional, only with a single roller. One downside to using one roller is it doesn’t provide as much agitation. So, consumers will need more passes to clean stains despite having more airflow. While the nozzle isn’t as bulky as Roborock’s, the Dreame H11 steering isn’t responsive.

The single tube design limits its turning radius, so it won’t turn as sharply as the Roborock Dyad. Vertical steering will be sub-par, with the fixed tube and single roller system not providing enough forward push. Since these machines only pick up everything in the forward pass, this can be a deciding factor.


Three-Rollers, Better Agitation: Roborock Dyad

  • Great for cleaning wet and dry messes
  • Above-average dirty water tank capacity requires fewer disposals
  • Excellent agitation on dry stains
  • Easy to steer around furniture
  • The open dirty water tank is easy to clean
  • Filter doesn’t get too dirty every after torture tests
  • Vertical steering is excellent


  • Not self-standing without the charging base
  • Bulky cleaning nozzle

Most hard floor washers (or wet/dry cordless vacuums) utilize one roller for debris pickup, but the Dyad has three. It’s the only one I’ve seen (so far) with this many rollers, and it helps with agitation and efficiency. Another benefit of having multiple rollers is that they propel the nozzle forward. So, despite being bulkier, it’s easier to steer around furniture.

The twin-axis steering system helps with this as it turns sharply, but the bulk hinders its reach under furniture, which is an issue with all hard floor washers. It has a twin water tank system, so clean and dirty water don’t mix. Roborock has larger water tanks than Dreame, which means fewer refills and disposals. The handle control makes it easy for consumers to toggle between the two power settings and the self-cleaning cycle.

Similarities between the Roborock Dyad and Dreame H11 Max

We’ll look at how these products are similar in this section.

1. Twin Water Tank System

Both Dreame and Roborock utilize a clean and dirty water tank system, so clean and dirty water are separate.

However, the liquid capacity varies with the Dyad having the larger capacity.

  • Clean water tank: 850 ml
  • Dirty water tank: 620 ml

Dreame H11 Max twin water tank system

Dreame H11 Max water tank capacity

  • Clean water tank: 700 ml
  • Dirty water tank: 400 ml

So it won’t require as many refills or disposals during usage.

2. Handle Controls

Dreame H11 Max and Roborock Dyad handle controls

Another similarity is the handle control placement. Both brands put it in the same location – the power and self-cleaning buttons.

One variance is that the Dreame only has one power setting, while Roborock has two.

Dreame’s second button is for the water absorption mode, which (frankly) is similar to its default cycle, so I don’t bother using it.

3. Interactive Screens

Dreame H11 and Roborock Dyad screen comparison

These products have interactive screens showing consumers real-time data like battery status, error codes, etc.

One difference is the H11’s larger screen with better readability than the Dyad’s smaller display.

Another variance is the battery status. Roborock displays it at five percent increments, while Dreame doesn’t.

4. Self-Cleaning Cycle and Charging Base

Dreame H11 Max and Roborock Dyad charging stand

The last similarity is the charging stand and self-cleaning cycle.

These wet/dry vacuums do well at keeping the roller(s) clean after the self-cleaning cycle. But please note that this feature will not work without the charging stand plugged.

Dreame’s base has storage for the extra roller, while Roborock does not. It’s a minor omission but something to consider.

5. Single Filter System

The Roborock Dyad and Dreame H11 Max utilize a single filter system with one primary filter inside the dirty water tank to keep allergens from leaking.

One plus for a wet/dry cordless vacuum is that water acts as a secondary filter, so there’s little risk of dust and allergens percolating.

Both products keep the filters clean since each has a mesh outer covering, protecting the inner paper element from large debris.

But Dreame’s filter is dirtier than Roborock’s after all the experiments.

Roborock’s filter is (slightly) cleaner, though there’s a noticeable build-up on the base.

6. Continuous Water Flow

The last similarity is the wet and dry functionality for both functions simultaneously, meaning water continually comes out of the sprayer.

There’s no way of shutting it off, unlike the Bissell Crosswave, which has a separate lever to spray water.

So I’d only recommend these products on sealed surfaces.

Differences between the Roborock Dyad and Dreame H11 Max

Next, we’ll look at the variances between these wet/dry cordless vacuums.

1. Number of Rollers

Dreame H11 Max and Roborock Dyad roller comparison

The most obvious difference is the number of rollers, with the Roborock Dyad having three and the Dreame H11 having one.

Roborock was thinking out of the box with their design, and it has several benefits.

First, it provides better agitation thanks to the larger surface area, and two additional rollers provide more scrubbing action.

Second, the three rollers propel the nozzle forward, making steering easier.

The Dreame H11’s single roller doesn’t offer much forward propulsion. Thus, steering suffers.

2. Steering Module

The following variance is the steering module. Dreame utilizes a single tube connecting the body and nozzle.

Dreame H11 Max steering module

One plus for the single tube design is it stands on its own even without the charging base. But the steering angle is compromised – it doesn’t turn as sharply as Roborock.

Roborock uses a more complex module with side-to-side movement.

Roborock Dyad steering module

This additional motion helps the Dyad steer around furniture better, but it prevents it from standing on its own without the charging base.

3. Dirty Water Tank Design

Aside from the volume difference, there are some subtle design variances with the dirty water tank.

Both have an open design with the bottom piece, making it easy to clean, but the top piece is different.

Roborock has a honeycomb-like outer filter piece with a detachable bottom that catches loose debris.

The bottom piece will catch loose dirt like Cheerios and hair.

Dreame’s upper filter piece has an open design with nothing to catch debris.

So most of the gunk will be inside the bottom container.

Avoid disposing of stuff like this inside the toilet bowl or risk clogging it.

Ergonomics Comparison

The Roborock Dyad is better than the Dreame H11 Max with ergonomics despite the heavier frame.

Its steering mechanism moves better around furniture, and consumers will not have any difficulty turning it even when it’s upright.

Dreame’s fixed tube doesn’t offer much with turning radium, and vertical steering is more challenging in tight spots.

Interface Comparison

Dreame H11 Max and Roborock Dyad

Both products have a similar design framework, meaning the clean and dirty water tanks are in similar locations and handle controls.

The display locations are also similar above the clean water tank, but Dreame has a bigger screen.

Airflow Comparison

I use an anemometer to measure the Roborock Dyad and Dreame H11 Max airflow. Check the table below for the results.

Roborock Dyad15.97 CFM18.52 CFM
Dreame H11 Max19.33 CFMN/A

There isn’t much difference with airflow, but the H11 Max has more at its single power setting than the Dyad in its max setting.

But airflow shouldn’t be a sticking point since these products use rollers that are excellent for picking up wet/dry messes.

Cleaning Comparison

Since these products’ wet and dry functionality operate simultaneously, it’s hard to do measured tests, so I’ll focus on the eye test with various before and after photos.

Overall, the cleaning performance for both is excellent on wet and dry messes.

Check these before and after photos for Roborock.

Worcestershire, and fish oil

It cleaned the trio of ketchup, Worcestershire sauce, and fish oil without any issues.

Edge cleaning is also excellent as it picked up this red wine spill.

I did the same tests with the Dreame H11 Max, which had similar success.

It picked up the trio with the same effectiveness as Roborock.

The impressive part for me is the effectiveness of the self-cleaning cycle at keeping the rollers clean.

Even with the huge mess, it successfully flushed away debris from the rollers.

There’s some hair on the Dreame roller, but the roller was clean despite the colossal mess it cleaned.

The result on Roborock is similar – clean rollers.

These rollers are also capable of picking up dry messes with efficiency. And with the ample clearance, both can pick up stuff like Cheerios.

Noise Comparison

The Dreame H11 produced less noise than the Roborock Dyad despite the higher airflow.

ModelDreame H11 MaxRoborock Dyad
Low75.2 dB76.0 dB
MaxN/A80.4 dB

It’s still noisy at over 75 decibels but not as loud as the Dyad’s loudest at over 80 decibels.

Maintenance Comparison

Even with the self-cleaning cycle, these products aren’t maintenance-free.

Junk will accumulate on the brush roller assembly and the charging base.

It’s essential to clean these areas to minimize unnecessary wear.

Dreame H11 Max dirt accumulation on inner wall

I’ll enumerate these areas/components that need cleaning.

  1. Roller: The self-cleaning cycle keeps the rollers clean, but disinfect them at least once a month using a mild disinfectant and rinse thoroughly.
  2. Roller assembly: Dirt and gunk will accumulate on the areas around the roller. Use a paper towel and brush to agitate and clean these areas lightly. Do this task once a month.
  3. Dirty water tank: Empty it after every mop cycle and rinse thoroughly before putting it back on the vacuum.
  4. Filter: These products’ simultaneous wet/dry function means there’s no need to clean this component as often. But if it gets too dirty, give it a thorough rinse, then dry it before reattaching.
  5. Charging base: Over time, the charging base will accumulate gunk. Please give it a visual check once every two weeks, then clean it with a paper towel to remove the build-up.

Which is the better option?

Each wet/dry vacuum has its unique selling points. The Roborock Dyad’s triple rollers offer better agitation and stain cleaning performance, while Dreame has the self-standing feature.

So which option should you choose?

To help you, I’ve enumerated reasons why you should select a specific variant.

4 Reasons to Choose the Roborock Dyad

  • Superb steering: The. Roborock Dyad’s steering is much better, even in tight zones. Its turning radius is sharper and goes around furniture with better ease.
  • More concise voice prompt: Its voice prompt is audible even with the motor running on full power.
  • Larger water tanks: The larger volume means less frequent refills and disposals.
  • Better stain agitation: The three-roller system offers better agitation and efficiency, so you’ll clean stains with fewer passes.

4 Reasons to Choose the Dreame H11 Max

  • Self-standing: It can stand independently even without the charging dock.
  • Larger LED screen: The H11 Max screen is larger, offering better readability than Roborock’s smaller display
  • More storage on the charging dock: The charging dock has slots for the extra roller and brush.
  • Efficient wet/dry pick-up: Its high airflow enables the H11 to pick up wet and dry spills even with one roller.

The Verdict: Roborock Dyad is the Better Performing Wet/Dry Vacuum

After testing these products extensively, the Roborock Dyad performed better in two critical areas – steering and stain removal.

Since my home is small, the former is a sticking point for me, and steering is crucial for usability.

The H11 Max performance is good and close to the Roborock Dyad, but lags with these crucial factors.

Yes, it can clean stains, but it needs more passes, thus affecting efficiency.

Consumers can force the H11 to turn sharply, but the movement won’t be as natural, and steering in tight zones will struggle.

Dreame should consider updating its steering module to have a better product. Otherwise, it won’t reach its full potential.
