The Best Cordless Vacuum

The Best Cordless Vacuum

Updated March 10th, 2021
the best cordless vacuum

Vacuum manufacturers have made it quite difficult to compare different models of cordless vacuums.

Manufacturers provide

  • Vacuum power in different units of measurement (airwatts, kPa, voltage, etc.)
  • Vacuum battery life in different conditions (cleaner head attached vs not attached, different power settings, etc.)
  • Other specifications like vacuum bin size and weight in different units of measurement and/or under different conditions

Our goal for this guide is to simplify comparisons by giving consistent measured data for all of the cordless vacuums we tested.

Power

We measured vacuum power in terms of airflow and suction.

We measured airflow (CFM)

  • At the cleaner head of the vacuum
  • On its highest power setting

We measured suction (inches of water lift)

  • At the main body of the vacuum
  • On its highest power setting

Here are our test results:

Battery life

We measured battery life

  • with a cleaner head attached to the vacuum and
  • with it running on its highest power setting

This describes how most consumers will use most of these vacuums most of the time - most consumers will primarily use them with a cleaner head attached and on high power, as performance drops off dramatically switching from high to lower power modes on most models.

Only a few models we tested offer adequate performance on lower power settings. Those models are listed in a separate table below.

Additional context

Note that we’ve included each vacuum’s performance in our carpet deep clean testing to add context to the battery life test results below.

Our carpet deep clean testing involved pushing the vacuum back and forth three times over an area of carpet embedded with 30g of fine debris. The tables below show how much of the 30g of debris was picked up by the vacuum in this test.

Top Rated Vacuums

Our recommendations of the best cordless vacuums on the market.

Tineco A11

The Tineco A11 is the best cordless vacuum for most people.

Of the 20+ cordless vacuums we’ve tested so far, it provides the best all-around cleaning performance and battery life for the price.

The A11 doesn’t have the highest airflow or suction. But it provides sufficient airflow and suction for most applications, and to get substantially more airflow and suction you have to buy a considerably more expensive vacuum.

The A11 doesn’t have the best battery life. But it provides sufficient battery life for most applications, and to get substantially better battery life you have to buy a considerably more expensive vacuum.

The bottom line is that the A11 may not provide the absolute best all-around performance, but it gets you close to it at a much more reasonable price than the absolute best performing models (like the Dyson V11). It also outperforms all other similarly priced cordless vacuums (like the Dyson V7 and V8).

There are multiple submodels of the A11 available but these are the two we recommend:

A11 Hero

The A11 Hero comes with only one battery and doesn't come with a soft roller cleaner head. As such, it's the least expensive A11 you can buy. In terms of airflow, suction, general cleaning performance, etc. it's identical to more expensive submodels like the A11 Master+. It just comes with less accessories and is a different color. If you're looking for the best value option, this is the submodel we recommend.

A11 Master+

The A11 Master+ is more expensive but it comes with an extra battery and a soft roller cleaner head for better hard floor performance. Its standard multi-surface cleaner head (which also comes with the A11 Hero) works fine for hard floors, but if you’re looking for the absolute best performance on hard floors and/or you need the extra runtime provided by an extra battery, this is the submodel we recommend.

Dyson V11 Outsize

The Dyson V11 Outsize is the best cordless vacuum not accounting for price and value.

No other cordless vacuum we tested offers a better combination of performance and battery life.

No other cordless vacuum we tested cleans more efficiently either. The Outsize has a uniquely wide cleaner head (which is about 25% wider than most other cleaner heads on the market) and a uniquely large dust bin (with a maximum capacity - at 1.5 L - that is about three times that of any other cordless vacuum we tested) which work in tandem to facilitate maximum efficiency while cleaning.

The one major downside for this vacuum is its price. The Outsize is a very expensive cordless vacuum.

But, if you want the best of the best and budget is not a concern, the Dyson V11 Outsize is our recommendation.

Alternative Options

Dyson V7 Fluffy

If you’re on a budget and need a cordless vacuum only for hard floors, the Dyson V7 Fluffy can be a good option.

The V7 Fluffy only comes with a soft roller cleaner head and so it can only clean hard floors (the soft roller head cannot clean carpet), but with its soft roller cleaner head it cleans hard floors very well.

The V7 Fluffy has considerably less battery life, doesn’t come with a swappable battery, and has a smaller bin than the Tineco A11, but if you’re only concerned about cleaning performance and price, it can be a good alternative to the A11 for cleaning hard floors.

Dyson V7 Allergy

The best budget alternative to the Tineco A11 for multi-surface (carpet and hard floor) cleaning is the Dyson V7 Allergy.

It again has less battery life, doesn’t come with a swappable battery, and has a smaller bin than the A11. But, it is often priced lower than the A11. And if you’re only concerned about cleaning performance and price, can be a good alternative to the A11 for cleaning a combination of floor types.

Michael chierottisays...

How do the A11 and S11 pure one Spartan compare

Consumer Analysissays...

I haven't had the chance to test the S11 Pure One Spartan yet, unfortunately, so I cannot really compare its performance to that of the A11.

Jennifer Dalysays...

I found an s11 tango on sale for the same price as the a11 hero ex. I have mostly hardwood floors and furniture and a long haired cat... Which would you buy

Consumer Analysissays...

I've unfortunately not had the chance to test the S11 Tango yet so I can't really compare it to the A11.
