Capacity, energy efficiency class, features and noise level: the few parameters that matter when choosing the right washing machine without paying for unnecessary features.
The right washing machine isn't the one with the most programs or the highest capacity. It's the one that washes your laundry well, with the load you actually do and with consumption you can afford over the years. A 10 kg drum that's almost always half empty costs more to buy, takes up more space, and doesn't wash better than a smaller machine used at full capacity.
In this guide we break down the few parameters that matter — actual capacity, energy class, useful functions, noise level — and give you a simple grid to decide without paying for features you won't use.
In brief: what you'll find in this guide
The short answer
For most Italian families the balanced choice is a 7-9 kg washing machine in class A or B, with Eco 40-60 program, spin speed of at least 1,200 rpm and delayed start. Capacity should be chosen based on your average weekly load, not the maximum stated value: a machine is efficient only when you fill it between 80 and 100%.
The practical advantage of thinking this way is twofold: you spend less on purchase and consume less with each wash. The downside of aiming too high on capacity is that you'll often wash half-full loads, wasting water and energy.
Capacity: the parameter most often got wrong
Capacity is expressed in kilograms of dry laundry. It's the data that weighs most on your choice, but also the one evaluated worst: there's a tendency to buy "large to be safe", getting the opposite effect. Here's a reference grid based on household size:
| People in household | Recommended capacity | Notes |
|---|---|---|
| 1-2 (single, couple) | 6-7 kg | Handles daily laundry, sheets and towels without problems |
| 2-3 people | 7-8 kg | The most flexible compromise for most homes |
| 4 people | 8-9 kg | Covers double sheets and a single duvet |
| 4 or more / large families | 9-12 kg | Only makes sense if full loads are frequent |
The practical rule is simple: a 7 kg machine always full is better than a 9 kg machine always half empty. A washing machine works best, in terms of consumption per kilo, when the drum is loaded between 80 and 100%. If your typical load is small, a larger machine doesn't save you money: it just costs more.

Energy class and actual consumption
As of 1 March 2021 the European energy label changed: the old A+, A++ and A+++ labels disappeared, replaced by a single and stricter scale from A to G. A washing machine that was previously "A+++" may now be in class C or D: it hasn't got worse, the measurement standard has changed.
The most useful data on the label isn't the letter, but the energy consumption per 100 cycles, measured on the reference Eco 40-60 program. This is the value that allows real comparisons between models. As an order of magnitude, a class A machine consumes around 45 kWh per 100 cycles, while a class G can exceed 80 kWh: almost double, for the same laundry.
The label also shows water consumption per cycle and the duration of the Eco program. Pay attention to a detail that surprises many: the Eco program is longer (often 3-4 hours) precisely because it works at lower temperature and for longer, and that's how it consumes less. The letter on the label refers to that program, not to quick cycles.
The functions that matter (and those you pay for unnecessarily)
The price difference between two washing machines is often made up of functions. Some are truly useful in daily use, others are mainly marketing.
Useful in practice
Delayed start: to start washing during more convenient hours.
Quality quick program: a 30-60 minute cycle for lightly soiled loads, without wasting an entire long program.
Automatic detergent dosing: avoids waste and residue on clothes, if you use liquid detergent.
Inverter motor: generally quieter, more efficient and with longer warranties.
To evaluate without exaggerating
Wi-Fi connectivity and app: convenient, but rarely decisive. Don't pay for them if you won't use them.
Dozens of special programs: in practice you'll use three or four. A very long list is not a sign of quality.
Steam and sanitizing: make sense for allergies or delicate fabrics; for common use they're an extra.
Noise and spin cycle
If the washing machine is in the kitchen, bathroom or near bedrooms, noise becomes a concrete criterion. It's indicated in decibels (dB) on the label, with a dedicated class for the spin phase: below 70-72 dB during spin is a good value for an apartment.
The spin speed, expressed in revolutions per minute, determines how wet the clothes are at the end of the cycle: 1,200-1,400 rpm is more than enough at home. Going beyond that does little, increases vibrations and stresses the fabrics more. If you then use a dryer, a good spin cycle saves time and energy in the drying phase.
Mistakes to avoid
Buying too much capacity "to be safe": you'll wash half-full loads and spend more, not less.
Looking only at the energy class: with the same letter, consumption in kWh/100 cycles can differ. Compare that number.
Being convinced by the number of programs: what matters is the quality of the few you'll actually use, not the length of the list.
Ignoring space and connections: measure depth, door opening and discharge and plug position before choosing.
Overlooking noise: if the room is near living or sleeping areas, it's a parameter you'll use every day.
The Portos choice
For typical household use, it makes sense to start with a 7-9 kg washing machine in class A or B, with inverter motor, 1,200-1,400 rpm spin, delayed start and a good quick program. This is the configuration that covers almost all real needs without pushing the price up on marginal features.
Choose capacity based on your average weekly load, not on the theoretical maximum, and compare models on consumption per 100 cycles rather than just the letter on the label. When you've narrowed down the options, it makes sense to compare prices and availability: you can compare models on SniffaPrezzi or see features and availability on OpportunityCommerce.

If you're also thinking about a dryer: capacity should be aligned with that of the washing machine, otherwise every load becomes two cycles. The full reasoning is in how to choose a dryer.
