Samsung appliance technologies, explained simply
EcoBubble, AI Wash, Digital Inverter, SpaceMax, Twin Cooling Plus, Dual Cook... Samsung loves its technology names. Behind each one is a simple idea, sometimes very useful, sometimes minor. Here's what they really do, appliance by appliance, and which ones are worth considering when you choose.
- Digital Inverter : brushless motor and compressor, guaranteed for 10 years (parts)
- EcoBubble : detergent turned into foam to wash at lower temperatures
- SpaceMax and Twin Cooling : more litres, better freshness
- SmartThings : useful for energy use and diagnostics
Why so many names?
Like many brands, Samsung gives a name to each function. Some names refer to a genuine technical difference (a motor, a refrigerant circuit), others to a programme option. To choose well, you need to tell the two apart. On this page, we rank each technology by appliance, with our verdict: essential, useful or secondary.
The 'up to' figures quoted here are those announced by Samsung. They are measured under specific conditions: in real life, the saving depends on how you use the appliance.
The heart of the appliances: Digital Inverter
This is the most important technology, because it concerns the part that works hardest.
- In washing machines : a brushless motor, with magnets. There are no brushes to wear out, it is quieter and uses less energy than a conventional motor.
- In fridges : a variable-speed compressor. Instead of switching on full power and then stopping, it runs gently and continuously. The result: a more stable temperature, less noise and less electricity.
- In tumble dryers : the heat pump compressor, also variable-speed, which allows for example the QuickDrive option that shortens drying time.
Our verdict : essential. It is a genuine durability argument.
Laundry technologies
EcoBubble and AI EcoBubble
A small generator mixes the detergent, air and water to form a foam before the wash. This foam penetrates the fibres faster than diluted detergent. You can therefore wash just as well at a lower temperature, and heating the water is the main part of a washing machine's energy use. The AI version adjusts the foam, the duration and the temperature according to the laundry. Our verdict : useful, especially if you often wash at 20 or 30 °C.
AI Wash and AI Wash+
Washing machines weighs the laundry, measures the dirtiness of the water using a sensor, and adjusts the water, the detergent (on models with automatic dosing) and the duration. AI Wash+, on the most recent 2026 models, also recognises several fabric types. Our verdict : useful for anyone who does not want to think about the programme.
Auto Dose and Auto Dispense
Two reservoirs, one for detergent and one for softener, which you fill for several weeks. The machine doses automatically at each wash. No more overdosing, which wastes detergent and leaves residue. Our verdict : very useful day to day, and often economical on detergent.
AI Energy Mode
A mode activated through the SmartThings app that reduces the energy use of compatible programmes by washing at a lower temperature and for a little longer. It requires the Wi-Fi. Our verdict : useful if you really connect the appliance.
Other names to know
- QuickDrive : a drum movement and water jets that considerably shorten certain programmes, according to Samsung. Secondary, unless you are always in a hurry.
- Super Speed : a quick full programme, around 39 minutes. Useful.
- Hygiene Steam : steam injected from the bottom of the drum for laundry hygiene, allergies and baby clothes. Useful for those cases.
- Bubble Soak : a foam soak against stubborn stains. Secondary.
- Drum Clean : a drum cleaning programme that needs no product, which the machine reminds you to run regularly. Useful, and worth actually doing.
- VRT : sensors and an algorithm that limit vibrations during spin. Useful in a flat.
Drying: heat pump and AI Dry
All Samsung tumble dryers sold here are heat pump models heat pump : hot air circulates in a closed loop and the water from the laundry is collected in a tank, like a fridge working in reverse. This is the most economical technology. The sensors AI Dry or Optimal Dry stop drying when the laundry is dry, instead of running for a fixed time. With a connected Samsung washing machine, Auto Cycle Link automatically chooses the drying programme suited to the wash that has just finished.
Laundry Combo
A washer-dryer that dries by heat pump, whereas conventional washer-dryers dry by condensation, which is much more energy-hungry. This is what allows it to be rated A for the full cycle, where others are rated D or E. Our verdict : the real innovation in the range, but the appliance is large and expensive.
Cooling technologies
SpaceMax
Better insulation allows for thinner walls. The fridge keeps the same external dimensions and offers more litres. For example, a 60 cm wide fridge-freezer reaches about 390 litres. Our verdict : useful, especially in a niche with fixed dimensions.
Twin Cooling Plus
The fridge and the freezer each have their own evaporator and their fan. The dry air from the freezer does not pass into the fridge: vegetables dry out less, and odours do not migrate to the ice cubes. Our verdict : essential for preservation.
All-Around Cooling and Metal Cooling
All-Around Cooling distributes cold air through several vents for an even temperature from top to bottom. Metal Cooling uses a metal plate that holds the cold and helps the fridge quickly recover its temperature after the door has been opened. Our verdict : useful, but not decisive.
No Frost
A fan circulates the cold air and prevents frost from forming. No more manual defrosting of the freezer. Our verdict : essential for comfort.
Family Hub, dispenser and adjustable drawers
- Family Hub : a large touchscreen in the door for notes, the calendar, music, recipes and controlling the home. Secondary for preservation, but appreciated in a family kitchen. More electronics also means more expensive parts outside the warranty.
- Water and ice dispenser : on American-style and multi-door models. Some require a water connection : check this before you buy.
- Drawers with adjustable temperature (CoolSelect, Optimal Fresh): a drawer that switches from chilled to extra-cold or light freezing, depending on your needs. Useful.
- Power Cool and Power Freeze : rapid cooling after the shop. Useful.
Kitchen technologies
Dual Cook and Dual Cook Flex
A divider splits the oven into two zones at two different temperatures. The Flex version adds a door that can open only on the upper section. Our verdict : useful for families and festive meals.
Natural Steam and Air Sous Vide
Natural steam adds moisture during cooking, for soft bread and tender meat. Air Sous Vide allows low-temperature cooking of food in a bag, using the oven's hot air. Our verdict : secondary, unless you're a keen cook.
Flex Zone and Dual Ring
On induction hobs, Flex Zone combines two rings into one large zone for oblong dishes. Dual Ring is a dual-ring burner that adapts to the size of the pan. Our verdict : useful if you cook with large cookware.
WaterJet Clean and automatic door opening
On dishwashers, WaterJet Clean refers to more powerful spray arms. Automatic door opening at the end of the cycle lets steam escape for better drying without heating any further. Our verdict : automatic door opening is really useful, especially for plastics.
SmartThings: the app that connects everything
SmartThings is Samsung's free app, available on Android and iPhone. It requires a Samsung account and the Wi-Fi at the place where the appliance is installed. What it really offers:
- Tracking : end of cycle, door left open, time remaining.
- Energy : each appliance's consumption and AI Energy Mode.
- Maintenance : reminders to clean the drum or filter, alerts in case of a fault.
- Diagnostics : in the event of a breakdown, the appliance can send information to Samsung's service team, which helps prepare the repair.
- Extra programmes : on some washing machines, dishwashers and ovens, cycles or recipes to download.
Connect your appliance on the day it is installed, even if you think you won't use the app. Maintenance reminders prevent many breakdowns, and when an error code appears, the app often tells you what to do. If the Wi-Fi doesn't reach the utility room, a small repeater will solve the problem.

Frequently asked questions
What is Samsung's EcoBubble?
A generator mixes detergent, air and water to form a foam before the wash. The foam penetrates the fibres more quickly, which allows effective washing at 20 or 30 °C and therefore lower consumption.
What does Digital Inverter mean?
It's the motor in Samsung washing machines and the compressor in Samsung fridges. Brushless and variable-speed, it's quieter, more economical and wears less. Samsung guarantees the part for 10 years, but labour and call-out charges remain your responsibility after 2 years.
What's the point of Wi-Fi on a washing machine?
Following the cycle on your phone, activating AI Energy mode, which reduces consumption, receiving maintenance reminders and making faults easier to diagnose. It isn't essential, but it's useful.
What is SpaceMax?
Better insulation that allows thinner walls. The fridge keeps the same external dimensions, but offers more litres inside.
Is Twin Cooling Plus important?
Yes, if you want food to keep well: the fridge and freezer each have their own cooling circuit. The very dry air from the freezer doesn't dry out vegetables, and odours don't pass from one compartment to the other.
Is Dual Cook really useful?
If you often cook two dishes at once, yes: a divider creates two zones at two different temperatures. For simple use, a standard pyrolytic oven is enough.
