Most Popular Vacuum Types and Their Power Requirements

When trying to describe how strong their vacuums are, many manufacturers use Air Watts, which is the strength of the airflow at the entrance of the vacuum.

Air Watts are related to the actual electric power, but they also depend on the suction motor efficiency, air flow pathways, tools being used, how clean are air filters and similar.

So, when talking about vacuum cleaner watts, we are going to discuss the actual electric watts of the vacuum cleaners, not their Air Watts.

After all, when paying electric bills, we are all paying for actual spent electric energy...

The most popular vacuum cleaner types are upright vacuums, corded stick vacuums, cordless stick vacuums, robot vacuums, and canister vacuums.

Other vacuum cleaners are used as well, but they are not as popular as these.

Suction Control

Suction control is very important when vacuuming various surfaces, but it also decreases power consumption.

Not all vacuums have suction control, and those that have suction control often have valves that decrease the suction on the nozzle while keeping the same airflow and the same motor wattage - mostly bagless vacuums with centrifugal air filtration require constant air flow to keep the air filtration at the required level.

Bagged vacuums, especially canister vacuums, often have very fine suction control, which increases or decreases motor power, thus regulating the airflow.

Upright Vacuum Cleaner Wattage

Upright vacuums are very popular vacuums and are often used as the main vacuums in homes and apartments.

Most upright vacuums are corded units rated from 600 to 1400 Watts.

For example:

  • Shark AZ3002 Stratos is a full-size corded, bagless, upright vacuum cleaner rated at 1416 Watts (120V 11.8A).
  • Bissell 2252 CleanView is another full-size corded, bagless, upright vacuum cleaner rated at 8 Amps (120V, 960 Watts).

While both units feature excellent performances for their own classes, Shark AZ3002 Stratos features stronger suction, but it also needs more energy.

Corded Stick Vacuum Cleaner Wattage

Stick vacuums are ultralight vacuums that are not as strong as upright vacuums but are easy to use and can be used quickly, even in emergencies.

Corded stick vacuums are often 2-in-1 vacuums that can be quickly converted from the stick vacuum cleaner configuration into handheld vacuum cleaner configuration and back.

Most corded stick vacuums are rated from 250 to 700 watts.

For example:

  • Shark HZ3002 Stratos (don't confuse it with the Shark AZ3002 Stratos) is rated at 600 Watts,
  • Shark HZ2002 Vertex is rated at 680 Watts,
  • Bissell 3070 PowerGlide Pet Slim is rated at 4.2 Amps (120V, ~500 Watts),
  • BLACK+DECKER BDXHHV005G 3-In-1 Upright Stick Vacuum is rated at 480 Watts, etc.

Some manufacturers also offer ultralight corded stick vacuum cleaners rated at 2-3 Amps (240-360 Watts), but they are good only for quick cleanups and are not very recommended for larger cleaning tasks.

Cordless Stick Vacuum Cleaner Wattage

Technically, cordless stick vacuums are very similar to corded stick vacuums, except that they are powered by onboard lithium batteries, not requiring the user to pull the power cord behind the unit.

Cordless stick vacuums are a very popular category, and with the advancements in technology, more and more cordless stick vacuums are being used as the main vacuum cleaner at home.

Most cordless stick vacuums are rated from 50 to 600 Watts, however, when talking about their electrical requirements, it is important to note the power of their battery chargers and not the rated power of the vacuums.

dyson v15 cordless

For example, the Dyson V15 Cordless Vacuum is one of the best and strongest vacuums on the market, featuring a maximum air suction of 230 Air Watts.

However, when its battery is fully discharged, it takes its charger ~4.5 hours to fully charge it again.

And its charger is rated at 30.45V and 1.1A (~33.5 Watts).

shark iz862h stratos

Similarly, Shark IZ862H Stratos is rated at 309 Watts (25.2V, 12.26A), and it comes with a 28.8V 0.8A (~23 Watts) battery charger that requires ~3 hours to recharge the battery completely.

Canister Vacuum Cleaner Wattage

Canister vacuums are almost exclusively corded units rated from 600 to 1400 Watts.

miele canister vacuum

For example, Miele Complete C3 Cat & Dog PowerLine Canister Vacuum Cleaner is a corded, bagged vacuum cleaner rated at 1200 Watts.

Also, it features very fine suction controls, allowing the user to adjust suction according to the surface being vacuumed.

Robot Vacuum Cleaner Wattage

Robot vacuums can't replace the main vacuum cleaner, but they can save plenty of time and effort.

Most robot vacuums come with charging stations that draw 2-5 Watts while on standby and anywhere from 25 to 50 or even more watts when charging the robots.

roomba j7 vacuum

For example, iRobot Roomba charging stations, on average, require 4W on standby and ~28-35 Watts when charging the batteries, which usually last ~3-4 hours.

Handheld Vacuum Cleaners

Handheld vacuum cleaners are somewhat weaker vacuums when compared with larger units since they are designed to be compact, lightweight, and used for quick cleanups.

shark handheld wv201 vacuum

Thanks to modern lithium batteries, most popular handheld vacuums are cordless, but some corded models are still doing well.

On average, handheld units' wattage ranges mostly around:

  • corded handheld vacuums: 100-600W,
  • cordless handheld vacuums: 50-200W.

Due to their power, operating time, and required energy, their influence on electricity bills is minimal.

Vacuum Cleaner Electricity Bill

The actual electric energy bill for the use of a vacuum cleaner depends on the vacuum usage frequency, the length of cleaning tasks, the tools being used, and similar.

But, if we assume that our hypothetical vacuum is:

  • rated at 1000W,
  • used 3x per week, 20 minutes per cleaning task,
  • 1 kWh of electric energy costs $US 0.15.

Then the monthly electric energy bill is:

$US = 3x 20 min * 1 kW * 4 weeks * $0.15 = 0.60 $US

Annually, that would be:

$US = 0.60 $US * 12 = 7.2 $US

So, the vacuum cleaner in the example needs 1 kWh per week, 4 kWh per month, and 48 kWh per year, and as such, it influences very little on the actual electric bill.

But, if you use your vacuum cleaner more often, the electricity bill may, nonetheless, go up.

How to Reduce Vacuum Electrical Usage

Efficiently managing your vacuum's electrical usage may save you money due to the smaller electricity bill. Here are some practical tips to help you minimize energy consumption while keeping your home clean:

Choose Energy-Efficient Models

Opt for vacuum cleaners with energy-efficient ratings or adjustable suction settings. Models with variable power settings consume less energy during lighter cleaning tasks, offering both versatility and efficiency.

Utilize Appropriate Attachments

Enhance efficiency by using the right attachments for different surfaces. Setting your vacuum's accessories to specific cleaning needs reduces the number of passes required, saving both time and energy.

Prioritize Regular Maintenance

Schedule regular maintenance tasks such as cleaning filters and removing debris from brush rolls. A well-maintained vacuum operates more efficiently, avoiding unnecessary strain on the motor and minimizing energy consumption.

Follow Smart Cleaning Patterns

Optimize your cleaning routine by starting from the farthest corner and working towards the exit. This strategy minimizes backtracking, saving both time and energy. Prioritize high-traffic areas where dirt accumulates for more efficient cleaning.

Use Short Bursts of Vacuuming

Instead of continuous operation, employ short bursts of vacuuming. Allowing the motor to rest intermittently not only conserves energy but also helps prevent overheating, prolonging the lifespan of your vacuum cleaner.

Disable Unused Functions

When cleaning hard floors or surfaces without attachments, deactivate motorized functions such as the brush roll to reduce energy consumption. Tailoring your vacuum's settings to the task at hand ensures efficient operation while minimizing power usage.

Consider Manual Cleaning for Small Messes

For minor spills or spot cleaning, opt for handheld vacuums or manual sweeping instead of using larger, more energy-intensive models. These compact alternatives are both convenient and eco-friendly for quick cleanups.

Choose Compact Vacuums for Basic Cleaning

Select lightweight vacuum cleaners for smaller spaces and routine cleaning tasks. Compact models are not only easier to maneuver but also consume less power compared to bulkier, more powerful alternatives, making them ideal for less demanding chores.

These strategies can effectively reduce the electrical usage of the vacuum cleaner while maintaining a clean and comfortable environment.

Note: for exact maintenance procedures of your vacuum cleaner, check the Owner's Guide.

How To Power Vacuum Cleaner In Emergency

If You have a charged cordless vacuum cleaner, it can be used in an emergency or during a blackout just as You would normally do - just keep an eye on the battery charge level.

However, if You wish to power your corded vacuum cleaner in an emergency, perhaps the best solution is to use a solar generator/portable power station.

A portable power station can be used indoors, and if it is strong enough, it can easily power even upright vacuums.

For the power station to be used for such purpose, 2000 Watts or stronger units are recommended with surge power of 3000 Watts or more.

Of course, such power stations may be used to recharge cordless vacuums and robot vacuum cleaners as well.

Note: during blackouts and emergencies, please, keep your smartphones and other telecommunication devices fully charged, just in case...


One such unit is the Jackery Explorer 2000 Plus Portable Power Station/Solar Generator, which is an expandable power station in terms of both capacity and the number of solar panels.

jackery explorer 2000 plus 1

Note: generally, these units without solar panels are labeled as "Power Stations" and with solar panels attached, they are labeled as "Solar Generators", but these terms are often used interchangeably.

Jackery Explorer 2000 Plus is not a small and cheap unit, but basic models come with a 2042Wh battery (expandable with up to five Jackery Battery Pack 2000 Plus (Amazon link, opens in the new window) units).

However, with its 3000W of output power, long list of output ports, and other features, this power station/solar generator can support residential vacuum cleaners up to 1500W easily.

Jackery Explorer 2000 Plus features physical dimensions of (L x W x H) 14.7 x 18.6 x 14.1 inches (~37.4 x 47.3 x 36 cm) and it weighs 61.5 pounds (27.9 kg).

Note: solar panels and additional batteries must be ordered separately.

The maximum output power of a single Jackery Explorer 2000 Plus unit is 3000W, with a 6000W surge peak. The power is delivered via a rather long list of output ports:

  • 4x AC Output:120V~ 60Hz, 20A Max,
  • 1x AC Output:120V~ 60Hz, 25A Max,
  • 2x USB-A Output: Quick Charge 3.0, 18W Max,
  • 2x USB-C Output: 100W Max (5V, 9V, 12V, 15V, 20V up to 5A),
  • 1x Car Port: 12V (10A).

Also, on the back of the unit, there is one DC Expansion Port (32.2-50.4V, 97A Max).

Input ports include:

  • Charge mode AC input: 120V, 60Hz, 15A Max,
  • Bypass mode AC input/output: 120V, 60Hz, 12A Max,
  • DC input: 2x DC 8mm Ports: 11-17.5V (Working Voltage), 8A Max; Double to 8A Max: 17.5-60V (Working Voltage), 12A Max, Double to 24A/1400W Max.

As one can see if you need to power your vacuum cleaner during the blackouts, one unit of this class is more than enough.

For the best offers and prices, feel free to check the Jackery Explorer 2000 Plus Power Station/Solar Generator Amazon link (the link opens in the new window).

Again, if there is an emergency or blackout, focus your efforts on keeping the smartphones and other telecommunication devices charged.

But, if there is really a need to vacuum in such conditions, note that 20 minutes of vacuuming with a 1500W vacuum cleaner at full power requires 750Wh of energy, and 6 minutes of vacuuming with a 1000W vacuum requires 100Wh of energy.
