DreameTech T30 Review

DreameTech T30 Review

A lot has changed since DreameTech released the V10 sometime last year. One of which is the new T-series culminating in the latest T30 we’ll look at in this review.

Based on my tests, this model currently has the most power and runs the longest at 91 minutes. Dreame told me that they aim to challenge the Dyson V15, but is it really that good? I’ve tested the V15 extensively, and it was one of the best-performing cordless stick vacuums. How does the Dreame T30 compare? Find out in this review.

Is It Better Than The Dyson V15 Detect?
  • Ergonomics - 95%
  • Surface Cleaning - 99.25%
  • Deep Cleaning - 94%
  • Quality - 94%
  • Design - 94%
  • Value - 96%


The DreameTech T30 is a solidly built cordless stick vacuum that performs well, especially on carpet. It rivals more expensive brands like Dyson, Tineco, and Miele with surface debris pick-up but lags a bit with embedded dirt. My primary concern for this product is its subpar steering and filtration, but that’s about it. If price is a deciding factor, then give this brand a long look.


  • High-end suction and excellent airflow
  • Excellent at cleaning surface debris on carpet
  • One of the best at picking up long hair strands
  • Lengthy run time – up to 91 minutes with suction-only tools
  • Automatically increases suction on carpet
  • The smart screen provides real-time data with run time, error codes, and more
  • Much cheaper than the Dyson V15 Detect


  • Quite noisy
  • It doesn’t have a fully sealed system
  • Not as good on hard floors
  • Short warranty (only one year)

Introduction to the DreameTech T30

One feature that intrigued me and why I agreed to do this review is the smart screen feature. Screens aren’t an entirely new feature, but I like Dreame’s usability and the contrast it brings to the table.

The colored text/graphics and black background provide excellent readability, and its position behind the motor gives users easy access to information.

The T30 has a sensor that counts debris and displays that information on the smart screen through a line graph.

It doesn’t measure particles like the Dyson V15 but only shows quantity like the Tineco Pure One S12.

This feature provides a visual cue on areas that are clean and not. However, it only seems to detect larger dirt particles.

I tried in on dusty zones, and the sensors don’t seem to track smaller particles better than larger ones.

Dreame Space 5.0 Motor

This variant has the Dreame Space 5.0 motor, spinning at a dizzying 150,000 RPM (25,000 more than the V15 motor) that generates up to 190 air watts of suction.

Now realize that RPM isn’t a sound basis to determine how well a vacuum will clean. To prove this, I tested the T30 suction versus the Dyson V15 Detect using a vacuum water lift gauge.

The T30 had an impressive 94″ of water lift, but six less than the Dyson V15 (100″).

So having higher RPMs doesn’t always equate to higher suction, as evidenced by this test.

But the T30 is on the upper echelon in terms of suction. It is higher than the V11 Outsize and V11 Torque Drive, which is impressive for a mid-priced cord-free vacuum.

Please note that I did the tests at the highest setting. I’m still fine-tuning the testing process, so bear with me if there are inconsistencies.

90-minute run time

Another selling point of the Dreame T30 is its lengthy 90-minute run time, thanks to the 2900 mAh Li-ion battery.

I tested it, and the claim is valid as it lasted for up to 91 minutes but with suction-only tools.

However, it lasted up to 55 minutes with the main nozzle – much shorter than the V15’s 85-minutes.

The battery is detachable, but it’s impossible to charge it separately because the charging pin is located behind the handle. This is one improvement that Dreame should look at in future releases.

Another unique feature I saw with the T30 is the LED-equipped crevice tool, helping to visibility and tracking dirt.

It’s the first of its kind I’ve seen and tested. Illumination isn’t too bring, but it still provides better visibility than something without it.

Dustbin design

DreameTech T30 dustbin

The T30 retains the same dustbin design as older T10 and T20 variants with a 0.15-gallon (or 0.66-liter) capacity. For cordless vacuum standards, it’s average, slightly smaller than the Dyson V11.

It has the same trap door design as the older models, but not the hygienic system or a Dyson.

One plus is it is fully detachable, and users can disassemble the different components if needed for a more thorough clean.

There are two primary filters – a pre-motor and post-motor HEPA. However, it doesn’t have a fully sealed system. I tested it using a fog machine, and there was a slight leak at the exhaust.

Trigger lock

DreameTech T30 Trigger Lock

One feature it has over the Dyson V15 is this electronic trigger lock behind the motor.

What it does is keep the motor on without having to squeeze the trigger, which improves usability when cleaning floors.

Ergonomics and usability

The T30 utilizes a similar design as the Dyson V8 but slightly heavier (3 pounds and 15 ounces vs. the V8’s 3 pounds and 7 ounces). So expect the same type of handheld ergonomics above floors.

However, the trigger lock gives it a slight advantage over the Dyson V8 because there’s less arm and wrist fatigue, plus the inclusion of a flexible hose makes the T30 better for handheld use.

Cleaning nozzle design

Dreame only included a single floor cleaning nozzle – the anti-tangle brush with the V-shape brush pattern and combs above to untangle hair. It doesn’t have a soft roller attachment included.

This design does work and one of the best (perhaps the best) at resisting hair tangles on carpets and hard floors.

While it picks up on hard floors well, it isn’t as efficient and doesn’t steer as well as a soft roller attachment.

The steering feels stiff, and it doesn’t turn as sharply as a Dyson, which is its biggest drawback.

How much power does the DreameTech T30 have?

I used an anemometer and vacuum water lift gauge to measure power.

Here are the results after the airflow test with the cleaning nozzle.

  • Low: 27 CFM
  • Mid: 30.64 CFM
  • Max: 41.91 CFM

And extension wand.

  • Low: 28.52 CFM
  • Mid: 36.95 CFM
  • Max: 58.35 CFM

The drop-off between the T30 and V15 is more significant with the airflow test than on the suction test – up to 22%!

It was much closer in the suction test, with the T30 having an excellent 94″ of water lift, only 6% less than the V15’s 100″.

Cleaning performance

Next, we’ll look at how well the T30 cleans floors. To check, I put it through my usual series of tests on debris types such as quaker oats, quinoa, coffee grounds, pet litter, sand, and hair.

  • Overall: 97.93%
  • Hard floor: 98.05%
  • Sand on hard floor: 99.8%
  • Carpet: 99.9%
  • Deep cleaning: 94%

The first thing that stands out is its performance on carpet, which is A+. It did better on this surface versus hard floors, which is expected since it only has the standard brush attachment.

Hard floor results

DreameTech T30 hard floor results

  • Quaker oats: 93.2%
  • Coffee grounds: 100%
  • Quinoa: 99.6%
  • Pet litter: 99.4%

It did the worst cleaning quaker oats, picking up only 93.2%. The problem isn’t pick-up but the lack of clearance. There isn’t much with the T30’s cleaning head, so a small portion of it was snowplowed.

Another issue is the lack of efficiency versus a soft roller attachment. I’m not a big fan of using standard nozzles for cleaning hard floors for this reason.

Sand on hard floor

Despite not having a soft roller attachment, the T30 still picked up sand well with a 99.8% average. But I had to use the max setting to achieve this score, highlighting the brush’s inefficiency.

Sand is one of the most challenging particles to clean on hard floors and requires exceptionally high airflow or agitation to pick up.

Edge cleaning

The T30 excels at cleaning edges needing only a few passes to clean this area.

It wasn’t as good in the quarter-inch crevice pick-up test, where it left some debris on this area.

Hair wrap test on hard floors

Next, we’ll look at the T30’s capability at resisting hair tangles on hard floors, and the results were excellent.

I used hair strands between five and twelve inches to torture-test this stick vacuum.

The results speak for themselves here. It picked up 100% in all the tests, much better than the Dyson V15, where twelve-inch strands wrapped on the roller and axle.

Carpet performance

This vacuum will do better on carpet due to the brush design and high suction. The results on low and mid pile carpet are proof of its capability. Having high suction and a good seal is essential to clean this surface well.

Low pile results

DreameTech T30 low pile results

  • Quaker oats: 100%
  • Coffee grounds: 99.2%
  • Quinoa: 100%
  • Pet litter: 100%

These are nearly perfect scores on low pile carpet – at par with the more expensive Dyson V15 Detect and V11 Outsize.

Mid pile results

DreameTech T30 mid pile results

  • Quaker oats: 100%
  • Coffee grounds: 100%
  • Quinoa: 100%
  • Pet litter: 100%

The T30 aced all the tests here with a straight 100% overall score. Again, the above-average airflow and brush dynamics are important factors why it picked up well.

Deep cleaning test

To check how well the Dreame T30 does at cleaning embedded dirt, I rubbed 100 grams of sand on mid-pile carpet. It picked up an average of 94% on two tests using the max setting, which is worse than the Dyson V11 Torque Drive, Outsize, and V15 Detect, but one of the best at its price bracket.

I also tried using the low and middle settings, and the results didn’t taper off much.

  • Low: 91.4%
  • Auto: 93.5%

It’s a decent percentage, but a notch below the V15 Detect on these settings. But considering the price difference, this vacuum is something to look at if Dyson is too costly.

Hair wrap test on carpet

Like on hard floors, the T30 is excellent at picking up hair on carpet. It successfully resisted hair strands – even 12-inch long hair without anything wrapping on the brush – better than the Dyson V15 Detect and Shark Vertex.

Hair wrapped on the brush initially, but hair eventually untangled after around 30 seconds.

Consider this cordless stick vacuum if you need to clean pet hair on either surface. If it can clean long strands, shorter ones shouldn’t be an issue.

How long will the DreameTech T30 run?

Dreame claims a 90-minute run time, and tests prove this figure to be accurate – 91 minutes to be exact, but only with non-powered tools.

Slap on the main nozzle, and that number goes down to 55 minutes.

How noisy is the DreameTech T30?

To check noise levels, I use a sound meter in each power setting, and here are the results.

  • Low: 71.4 dB
  • Mid: 72.4 dB
  • Max: 78.3 dB

This vacuum is loud, which shouldn’t surprise you since most high suction cordless vacuums will produce a lot of noise.

Availability of parts

DreameTech being a new brand means parts availability will not be as abundant. The good news is that this company has been active with product releases, which means it is committed to improving. However, I don’t see much with parts availability on Amazon. Most of the accessories sold are for robot vacuums, but not stick vacuums. Only time will tell if this changes.

Does the DreameTech T30 offer good value?

The high suction and superb carpet cleaning results at its price make the T30 an excellent value-for-money alternative to the Dyson V15.

Realize that the T30 won’t steer or deep clean as well as the V15 Detect, especially in the low and auto settings.

Hard floor performance is decent, but I’d prefer using a soft roller on this surface. But that’s my preference, and the T30 can clean this surface well enough to warrant consideration.

This vacuum isn’t without its flaws. I’ve highlighted two, but the difference between this and the V15 Detect as wide as the price difference would suggest.

5 Reasons to consider the DreameTech T30

  1. High suction: The T30 only trails the V15 Detect with suction with up to 94″ of water lift.
  2. Excellent performance on carpet: This vacuum will clean carpets well thanks to its high suction, solid brush dynamics, and seal.
  3. Superb hair pick-up on both surfaces: The results speak for themselves with the T30. It was the best so far at resisting hair tangles, even from 12-inch hair strands.
  4. Handheld ergonomics: Usability above floors will be better with the flexible hose and trigger lock.
  5. Lengthy run time: It lasted up to 91 minutes in my tests – an impressive number from a single battery.

The Verdict: Value for Money Alternative to the Dyson V15

Despite its flaws with steering and filtration, the DreameTech T30 is an excellent option to consider if the Dyson V15 is too expensive. The price difference is a good enough reason to contemplate this option if you don’t mind the downsides I’ve outline in this review.

Being a Xiaomi-backed firm does help as this company is known for manufacturing high-quality products.

Only time will tell if it’ll be popular enough that third-party manufacturers will start selling parts like the battery. For now, as it stands, the T30 is a decent Dyson alternative that won’t break the bank.
