DreamTech T20 cordless vacuum cleaner with all-in one HD screen review


With the dimensions 126,5 x 25,5 cm the teat is also usable for people up to 1,95 m (6ft 4″) without any problems (here again my hugely grown, younger 2-m-brother (6ft 6″) can be used) Also the weight of 2,7 kg completely removed (incl. suction pipe and floor nozzle) does not spoil the comfortable handling.

LCD display

The display shows a wealth of information:

  • Charge level in percent
  • four suction levels (Eco, Med, Auto, Turbo)
  • Trigger locked or unlocked (continuous vacuuming or pressing)
  • Note that the HEPA filter must be cleaned
  • Language selection (English and German available)
  • Various error messages (low battery power, roller must be cleaned, filter not inserted correctly, etc.)


The T20 generates up to 150 AW suction power, which can easily clean surfaces such as hardwood floors, thick carpets, and beds with different brushes. The intelligent adaptive suction power with auto-mode can detect different surfaces and change suction power accordingly.

Filter & dust chamber

The entire filter system can be easily washed out under the sink. Depending on the intensity of use, this makes sense every two to three months. Also the emptying of the 0.6 l dust chamber is well thought out by the manufacturer. All the user has to do is press a button (trash can symbol) and the contents of the chamber tumble out. It is therefore essential to perform the process above the trash can.


The surface brush and floor nozzle on this vacuum cleaner have been enhanced with sensors to detect the kind of surface it is on automatically. Therefore, the Dreame T20 will immediately adjust the suction level as well as the suction power depending on whether it’s a hard floor or carpet.


The T20 Cordless Vacuum Cleaner has an impressive run-time of 70 minutes, the longest in the market, and it can be further extended to 140 minutes with an additional detachable battery. Both batteries can be charged at the same time with its wall-mounted storage cum charging dock, which enhances the user experience.

Cleaning modes

Its four cleaning modes quickly and easily cleans up ground-in dirt in furniture, beddings, car seats as well as unreachable places like gaps in tile or wood floors. The Dreame T20 vacuum also features five stages of filtration systems that captures 99.97% of the dust and allergens in your living space. While at the same time expelling clean, fresh air. This T20’s filter system will leave your home safe and comfortable.

DreamTech T20 cordless vacuum cleaner with all-in one HD screen Performance review

After a charging time of 4 h the T20 is ready for use for a working time of 70 (Eco), approx. 30 (medium suction stage) or 10 min (Turbo). This is 20 min. less on the lowest suction stage than on the predecessor V11, but still a very good value compared to many other models (Dyson V11 Absolute for example provides 60 min. Otherwise you can also use the second battery.

It would have been nice to compare the floor nozzle with attached carpet roller with the Torque Drive of the V11 Absolute, but unfortunately it was still in development for the test phase. With the soft roller in combination with the 25.000 pa suction power (just below the previous best value) you are equipped with sufficient feeding power for carpets, but not with the right roller. The special carpet roller should be much more suitable for this purpose than the soft roller. With our advance delivery scope we are not optimally equipped for use on carpets.

Is better Dyson V11 than DreamTech T20 cordless vacuum cleaner with all-in one HD screen?

Inside the T20, the motor operates at 125,000 rotations per minute, which corresponds to the motor value of the Dyson V11 Absolute. But what I find particularly positive after dozens of laps is a different motor – namely that of the bottom nozzle. You only have to give the T20 the direction, the engine does the rest by itself. So you have less the feeling of doing annoying housework and more the feeling that vacuuming can also be fun. It really does with a good cordless vacuum cleaner like the T20.
