Xiaomi Dreame T30 vs Dyson V15: At first glance, you will find the first one is significantly cheaper. The question is, “Which is better value for money?”
If you don’t mind splurging on a high-quality stick vacuum, I highly recommend the Dyson V15. It has unparalleled suction power and can suck up dust like a champ on any surface. It also has a great filter system and a good set of attachments.
The Dreame T30 is a great addition to Dreametech’s line, and I’d like to say it’s worth the money. Not to mention other factors, this machine’s powerful suction and incredible performance are enough to make it an excellent choice for any homeowner. Of course, these are insufficient to defeat the Dyson V15.

Xiaomi Dreame T30 vs Dyson V15: Differences
The Dyson V15 wins 3-0 and draws once against the Dreame T30. Aside from cleaning performance, the V15 outperforms its competitor in every category, including design and usability, dust cup capacity and filtration system, and utilities.
Cleaning Performance
Winner: Tie
Suction Power
The Xiaomi Dreame T30 and Dyson V15 produced maximum suction power of 190AW and 230AW, respectively. On paper, the second one should perform significantly better than the other in terms of cleaning. However, my testing found very little difference.
Hard Floor
The Dyson V15 comes with two floorheads: Laser Slim Fluffy and High Torque 2.0, which are designed for vacuuming hardwood and deep cleaning carpets, respectively. Meanwhile, the Dreame T30 is only packaged with a V-shape roller floorhead, which was, in my opinion, ideal for deep cleaning carpets.
The Dyson V15’s Laser Slim Fluffy Head has a soft roller that is removable and washable. My testing showed that it could pick up all the dust and debris easily and smoothly on my hardwood floor without scratching it. I also found a switch that is used to turn a green laser on, which came in handy in vacuuming poorly lit areas.
As for the Dreame T30, it pushed a fair amount of debris to the back, resulting in parts of the mess that didn’t get vacuumed up. I made more than two passes and still couldn’t get rid of everything, and I thought using the combination tool would be more effective.
Carpet
I found that the Xiaomi Dreame T30 worked great on carpets, with nothing left behind after just one pass. Similar outcomes were also obtained by using the Dyson V15 with the High Torque 2.0 floorhead. That’s what sets them apart from most cheap sticks.
Hair Removal
Both the Xiaomi Dreame T30 vs Dyson V15 were able to suck up most, if not all, of the hair I dropped on the floor and carpet. With the V-shaped roller, the Xiaomi Dreame T30 did a wonderful job at preventing hair wrap.
The Dyson V15 could also limit hair wrap problems thanks to the polycarbonate teeth system on its motorized cleaning head. It wasn’t as perfect as the Dreame T30’s spiral brushroll, but it worked.
Design And Usability
Winner: Dyson V15
Dimension And Storage
The Xiaomi Dreame T30 vs Dyson V15 dimensions are 49 x 13.6 x 9.8 and 49.6 x 10.5 x 9.8 inches, respectively; there is not much difference here. They fit easily under my coffee table and couch, but I usually attach them to the charging dock after each cleaning session. That way, the machine will be automatically fully charged and ready for the following vacuuming session.
There is no way to store attachments on the Dreame T30’s body, while its charging station only has room for two accessories. That means you’ll need to store the two other accessories somewhere else.
The Dyson V15, better yet, comes with a wand clip that allows storing two attachments on board, whereas its wall charger can hold two other attachments.
Weight And Maneuverability
The Dreame T30 weighs 6.3 pounds, while the Dyson V15 weighs 6.8 pounds. I didn’t feel this 0.5-pound difference in my hands because they were both as light as a feather. When converted to handheld vacuums, they are even lighter (under 4 pounds).
In terms of maneuverability, the Dyson V15 prevails since it has a swivel head, while the Dreame T30 doesn’t. With the help of the attachments (low-reach adapter and flexible elbow joint, respectively), I was able to slide the Xiaomi Dreame T30 vs Dyson V15 under my interior without bending over.
Battery Life
The run time of a cordless stick vacuum depends on various factors, but the chosen suction setting is the biggest one. I tested the battery life of these machines and found the following:
| Mode | Xiaomi Dreame T30 | Dyson V15 |
| Eco | 49 mins | 71 mins |
| Auto | 25 mins | 34 mins |
| Boost | 10 mins | 8 mins |
The V15 comes with a 3600 mAh seven-cell battery, Dyson’s latest and largest battery technology. On the other hand, the 2900 mAh Li-ion battery powers the Dreame T30. That’s why the Dyson V15 could last longer in most cases.
The manufacturer said that the Dreame T30 could run for up to 90 minutes on the Eco setting, and as you can see, my results were far behind their statement. Perhaps dishonesty in advertising is quite common these days. Anyway, its battery life was sufficient for me to complete the vacuuming session without having to recharge in the middle.
The battery of both is detachable, but I couldn’t charge the T30’s separately since the charging pin is located behind the handle. The Dreame engineers should consider this for future models.
Dust Cup Capacity And Filtration System
Winner: Dyson V15
The Dyson V15’s dust cup has a capacity of 0.75 liters, while the Dreame T30 comes with a 0.66-liter dirt bin. The difference is negligible, and I found myself frequently emptying them during testing. Although the procedures for emptying these dust canisters vary, they all share the benefit of being simple and “no contact with the dirt.”
When it comes to the filter, the duo has a washable HEPA filter. But this filter is only available with the Dyson V15 Detect Absolute. So don’t be surprised if you can’t find it if you choose other models, such as the Dyson V15 Detect or the Dyson V15 Detect +.
The Dyson V15 takes the lead with a sealed system that keeps the sucked air inside the unit and ensures it is properly filtered before escaping. The Xiaomi Dreame T30 has no fully sealed system, so allergens can escape. This is a deal breaker for people with severe allergies, although it won’t be a full-blown leak.
Utilities
Winner: Dyson V15
LCD Screen
There’s an LCD screen on top of the Dyson V15, which keeps me well-informed about my chosen cleaning mode, estimated remaining run time, maintenance alerts, and particulate data. It has an onboard Piezo sensor that can count and sort vacuumed debris into four sizes: 10, 60, 180, and 500 microns.
The Dreame T30 also features an OLED screen located behind the motor. Its black background and colored graphics/text gave me excellent readability. It also is fitted with a sensor that can count debris and show this on the screen through a line graph. It only displays quantity rather than particle size, as the Dyson V15 does.
Vacuuming Setting
The Dyson V15 features three cleaning modes, including Eco, Auto, and Boost, while the Xiaomi Dreame T30 has four vacuuming settings: Turbo, Medium, Eco, and Auto. Your selected vacuuming setting will be displayed on the LCD screen.
| Turbo | Max suction – Shortest run time |
| Medium | Moderate suction – Average run time |
| Eco | Min suction – Longest run time |
| Auto | Variable suction – Variable run time |
On/Off Trigger
The Xiaomi Dreame T30 vs Dyson V15 share an on/off trigger that I pressed to activate the vacuum. One thing the Dreame T30 has over the Dyson V15 is an electronic trigger lock behind the motor that is used to keep the machine running without squeezing the trigger. This trigger lock gives the T30 a slight advantage over its competitor since it minimizes arm and wrist fatigue.
Attachments

Charger. 2.0 High Torque floorhead. Fluffy cleaning head. Crevice tool. Hair screw tool. Combination tool. Soft dusting brush. Stubborn dirt brush. |
It is clear that the Dyson V15 is packed with a better and richer set of attachments. I was very impressed with the LED-equipped crevice tool that came with the Dreame T30. It was the first time I’d seen and tested a crevice tool equipped with an LED light. It wasn’t very helpful, but half a loaf is better than no bread!
