Pay attention to low wattage when buying a vacuum cleaner

If you want to buy a new vacuum cleaner, you cannot currently rely on the energy efficiency classes. Because vacuum cleaners that are new to the market have not needed a label since the beginning of 2020. Energy-conscious people can orient themselves on the wattage and independent consumer tests.

The essentials in brief:

The energy label has not been applicable to vacuum cleaners since the beginning of 2020.

If you want to save energy, you can pay attention to a low wattage and independent product tests.

Since electricity consumption is low overall, it is not worth replacing old vacuum cleaners.

Which criteria play a role in the purchase?

If you want to buy a new vacuum cleaner in USA, you can choose from around 1000 different models. But what is important to you when choosing? Is it the price, with or without a bag, with cable or battery, suction power, volume, energy consumption, weight, or whether the device is suitable for allergy sufferers? Another criterion can be the practical handling, i.e. how well the vacuum cleaner gets into corners, whether it drives smoothly or even vacuums itself.

Independent test results provide good guidance for the purchase decision. Detailed information on suction quality.

Wattage provides information about electricity costs.

Since the beginning of 2020, the efficiency classes of the USA have been used as a yardstick for the energy consumption of vacuum cleaners for the time being. Since then, dealers can no longer advertise vacuum cleaners with the label. Devices that are new to the market no longer need the previously required USA-wide proof of energy consumption.

If you want to buy a new vacuum cleaner, you can now use the manufacturer’s information on the performance of the device, i.e. the wattage, as a benchmark.

The most economical vacuum cleaners have around 400 watts. With 52 hours of operation per year (1 hour per week), they consume no more than 21 kilowatt hours (kWh). That makes a little less than 6 US Dollars electricity costs a year.

Less efficient vacuum cleaners with a wattage of up to 900 watts can consume 43 kWh per year and thus cause electricity costs of just over 11 Dollars.

The average working prices of 27 cents per kilowatt hour of electricity were used as the basis for the calculations; a basic price was not taken into account. You can find an overview of energy prices in NRW in our tool.

So you can’t really save a lot with a particularly economical vacuum cleaner. That’s why it’s not worth replacing old, still working vacuum cleaners – even if they still have 1600 watts.

Also important: The wattage does not automatically say anything about the suction power and cleaning power of a device.

Decibel specification: How quiet is the vacuum cleaner?

Vacuum cleaners can cause considerable noise. When buying, make sure that the device is as quiet as possible. The noise level is given in decibels. We perceive any increase in sound of around 10 decibels as a doubling of the volume.

The noise level of vacuum cleaners is 70 to 90 decibels; very quiet vacuum cleaners currently reach less than 65 decibels.

Cable or battery?

Are you considering buying a cordless vacuum cleaner because you don’t have to pull the annoying cable behind you? Then you should definitely take a look at the results of the Stiftung Warentest. Accordingly, not all models tested convince in terms of suction power. In addition, some devices immediately blow out a lot of dust and the dust box is often difficult to clean. In addition, the battery vacuums are quite loud (80 decibels), and the battery does not last long, so you have to charge the vacuums frequently.

Although they require less electricity than conventional vacuum cleaners, their cleaning quality is often (still) not comparable to that of a good vacuum cleaner.

Conclusion: The cordless vacuum cleaners are only suitable for quick vacuuming in between and for pet owners. Because the cordless with a rotating brush scores when it comes to removing animal hair from carpets

Dust filter as protection for allergy sufferers.

Multiple filters in the form of a double-layer paper bag for coarse dirt are standard for hand and canister vacuum cleaners. Most dust bag packs include engine protection and one or more exhaust filters. With the help of electrostatic charging, these micro filters can hold particulate matter particularly well.

If you are allergic to house dust, make sure that the device has a HEPA or ULPA filter. These special exhaust air filters retain more than 99 percent of all particles up to a size of 0.3 micrometers (human hair has a diameter of approximately 50 micrometers). The smallest particles such as pollen, bacteria and dust mite excretions, which are responsible for the house dust allergy, hold back these filters.

A filter change indicator, which is usually present, signals when you should replace the dust bag.

Brush vacuums are specialists for households with animals

Brush vacuum cleaners have a built-in rotating brush that combs the dirt out of the fibers. They are particularly suitable for homes with pets that lose hair. If you suffer from allergic symptoms, make sure to use a HEPA filter.

Brush vacuum cleaners are now also available with a dust container instead of a dust bag.

Pay attention to the weight, because brush vacuums are heavier than vacuum cleaners with sledges.

Robot vacuum: practical, but expensive

Even the best automatic / app-operated vacuum robots cannot keep up with a good vacuum cleaner when picking up dust. It’s more about removing visible dirt or animal hair.

They are particularly suitable for smooth floors and rooms with little furniture, because they have to navigate through the rooms regularly and obstacles are not always easy for them to overcome.

Their performance and power requirements are rather low, even if they remain in stand-by mode all year round and are intended to be used almost every day. When choosing, pay attention to the consumption, the suction power and the volume. The price differences are significant. Compared to vacuum cleaners, vacuum cleaning robots are much more expensive.
