Dreame Z20 : complete overview

Dreame Z20: ultra-powerful 250 AW suction and 140,000 RPM motor

The Dreame Z20 pushes the boundaries of cordless stick vacuums with 25,000 Pa (250 AW) of suction power driven by a 140,000 RPM high-speed motor. This combination of raw power and rotational speed dislodges even the most stubborn dust from all floor types, from delicate hardwood to deep-pile carpets. Weighing 1.85 kg, the Z20 remains manoeuvrable and comfortable for daily use despite its benchmark-setting power.

CelesTect technology on both brushes and 99.99% filtration

The Z20 features CelesTect LED technology on both included brushes: the multi-surface brush and the soft roller. The built-in LEDs illuminate dust particles invisible to the naked eye on hard floors, revealing areas that need an additional pass. The full-path HEPA filtration captures 99.99% of particles at 0.3 microns and above, ensuring exceptionally pure expelled air for households with allergy sufferers.

Smart infrared dirt detection and real-time LCD display

The Z20's smart dirt detection system uses infrared sensors to analyse dust density and automatically adjust suction power. The LCD display shows the selected mode, battery level, cleaning results and maintenance alerts in real time. With 90 minutes of runtime in Eco mode and versatile accessories, the Z20 covers every domestic cleaning scenario.

250 AW and 99.99% filtration: genuinely impressive

The Dreame Z20 at 250 AW is a powerhouse for a cordless stick vacuum. On our thick rugs it dislodges every bit of embedded dirt. The full-path HEPA filtration at 99.99% is brilliant for our son who suffers from dust mite allergy. The LCD display shows everything in real time. The infrared sensor adjusts power automatically. 90 minutes in Eco covers our entire home.

CelesTect LED on both brushes is brilliant

The Z20 comes with two brushes featuring CelesTect LED technology: the multi-surface and the soft roller for hardwood. The LEDs illuminate hidden dust on hard floors that you simply cannot see otherwise. The infrared dirt detection works seamlessly and adjusts power as needed. 250 AW, 140,000 RPM, 99.99% filtration: this is serious kit.

LCD display and infrared detection are excellent

The Z20's LCD display is clear and shows mode, battery and cleaning results in real time. The infrared dirt detection is effective: the vacuum speeds up when it detects a dirty area. 250 AW of suction is remarkable. Only wish is that it had a flexible tube for getting under low furniture. Otherwise an outstanding vacuum.

Perfect for allergy sufferers with HEPA filtration

Our daughter has a dust mite allergy and the Z20 with its 99.99% full-path HEPA filtration has made a genuine difference. The expelled air is noticeably purer than our previous vacuum. 250 AW handles all dirt effortlessly. The soft roller is gentle on our hardwood floors. A thoughtfully designed vacuum.

Powerful but no auto-empty station

The Z20 is undeniably powerful at 250 AW. The LCD is clear, infrared detection works well, 99.99% filtration is reassuring. Both CelesTect brushes are a genuine advantage. But at this price point the lack of an auto-empty station is disappointing. The 600 ml bin fills up quickly with our two cats. Still a very good vacuum overall.
