Everyone in this category says they tested twenty vacuums. We have not tested any, and we say so. What we do instead is read the manuals, compile the published specifications, and work out what each machine costs to run for three years — the method is written out in full.
We earn a commission if you buy through the links on this page, at no extra cost to you. It never changes what we recommend or the order we recommend it in. Full disclosure.
Buy corded if your floors are mostly hard, if your budget is under about $100, or if you want a machine that still works in 2034. Buy cordless if you will only use a vacuum that is grab-and-go, or if stairs and above-floor work are most of the job. The convenience of cordless is real; so is the fact that its most expensive component wears out.
The published power gap is large
Compare like with like on manufacturer figures. A Shark IY143H cordless publishes a 181 W motor. A Shark NV356E corded upright publishes 1,200 W. A Bissell CleanView Swivel Pet publishes 800 W. A Eureka Whirlwind canister publishes 960 W. Those are consumption figures rather than airflow figures, so they do not translate directly into cleaning — but the gap is not subtle, and it is why no cordless machine on this site is recommended as a deep-pile carpet solution.
The other half of the gap is that a cord does not fade. Every cordless runtime figure on this site is a rating, and every one of them describes a battery that is at 100%. A corded machine's last minute is identical to its first, this year and in five years.
The three-year cost, worked out
Electricity is the part everyone assumes matters and it does not. At the U.S. average residential price of 18.34 cents per kWh, here is what each machine costs to run for three years at 45 minutes of vacuuming a week:

45 min/week x 156 weeks = 117 hours. Cordless machines draw only while charging, and none of these manufacturers publish charger consumption, so a cordless row would be a guess — which is why there is not one.
Thirteen dollars over three years, for the thirstiest machine here. Electricity is not the cost of owning a vacuum. The costs are filters, bags and — on a cordless — the battery.
Where cordless genuinely wins
Frequency of use. A vacuum you can grab in four seconds gets used four times as often as one you have to unwind. That is not a spec, and it might be the most important thing on this page.
Stairs. Dragging a 13.7 lb corded upright up a staircase is a task. Carrying a 5.3 lb cordless is not.
Cars, upholstery and ceilings. A handheld conversion with no cord is simply better at every above-floor job.
Small spaces. In a one-bedroom flat, 40 rated minutes is two full cleans and the cord is pure friction.
Where corded genuinely wins
Deep carpet. 800 to 1,200 published watts with a driven brushroll is a different class of machine from 181 W.
Big floors. No runtime limit means no interruption, and no anxiety about mode selection.
Cost over five years. No battery, washable filters on most of these, and a running cost that rounds to nothing.
Capacity. The Eureka Whirlwind's 2.5-liter bin and the PowerSpeed's 1.9 liters dwarf anything cordless.

01 · Best for hardwood
Shark Rocket Pet Plus Corded Stick (HV322)
Under 10 lb, 500 W, corded, with a low-profile head that actually fits under furniture — the hardwood answer that never needs charging.
Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+500 W of constant power on hard floors, with none of the fade a battery gives you at minute 30
+Converts to a handheld and clips into freestanding storage
+Low-profile head reaches under couches that a full upright cannot
Where it stops
−Foam filter, not HEPA
−0.68-quart cup
−The cord is the whole compromise and there is no getting around it
Who it is for
Hardwood, tile and LVP homes with rugs, where constant suction matters more than cordless freedom.
Skip it if
Deep pile carpet is your main surface. A 500 W stick is not a substitute for a proper upright on thick pile.

What the numbers say
+Names its filtration test standard AND the lab that ran it — the most specific filtration claim on this site
+1,200 W on a driven brushroll deep-cleans carpet properly
+Lift-Away pod covers stairs, which is where most uprights fail
Where it stops

−Washable filters need genuine drying time, and people skip it
−Corded, with everything that implies
Who it is for
Allergy households on carpet who want measured filtration rather than a bare percentage.
Skip it if
You have a lot of stairs and no storage. It is heavy, it is bulky, and the Lift-Away pod only partly solves that.

What the numbers say
+0.7-quart cup is double the IX141's, which is the difference between one empty and three
+Self-cleaning brushroll is published as anti-hair-wrap, and that claim is specific rather than decorative
+FloorDetect removes the nozzle-swapping step between rug and hardwood
Where it stops
−Still no published suction figure
−Heavier than the IX141 by 0.2 lb, which you notice on stairs and nowhere else
−Battery is not published as user-removable on this model
Who it is for
Pet households with a mix of rug and hard floor, where hair wrap is the actual daily annoyance.
Skip it if
Your floors are entirely hard surface and nothing sheds. You are paying for the anti-tangle brushroll, and on bare floor it does nothing for you.

04 · Best canister under $120
Eureka Whirlwind Bagless Canister (NEN110A)
960 W, a 2.5-liter bin, automatic cord rewind and washable filters — the canister case, made cheaply and made honestly.
Telescoping metal wand with integrated crevice tool
Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+2.5-liter bin and washable HEPA — no bags, no filter bills
+The body stays on the floor, so stairs and above-floor work are far easier than with an upright
+Automatic cord rewind, which is a small luxury that is missing at this price everywhere else
Where it stops
−No powered brushroll, so deep pile carpet is not its job
−Dragging a canister around furniture annoys some people permanently
−82 dB
Who it is for
Hard floors, stairs, cars and upholstery — the classic canister case.
Skip it if
Wall-to-wall carpet is your main floor. Suction alone does not agitate pile; you want a driven brushroll.

05 · Best under $80
Bissell CleanView Compact (3508)
Under 8 lb, corded, 1-liter tank and a washable filter — the cheapest way to own a vacuum with no battery to replace.
Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+No battery, so the three-year running cost is a washable filter and nothing else
+Scatter-free hard floor design, which is the usual failing of a cheap upright
+Light enough to carry upstairs one-handed
Where it stops
−You are tethered to an outlet, and that is the whole trade
−No HEPA claim
−Small machine, so a whole-house clean means moving the plug a lot
Who it is for
Apartments, dorms and anyone who wants the lowest possible cost of ownership over five years.

The reason you are shopping is that you hate cords. Nothing about this machine will change your mind and you will not use it.

The answer most households actually want
Both, and cheaply. A corded upright or canister for the weekly clean, plus a very light cordless or corded stick for the two-minute jobs, frequently costs less than one mid-range cordless machine — and it is a better outcome, because each tool is doing the job it is designed for.
If that sounds like an evasion, look at the prices. The Bissell CleanView Compact and the Eureka Blaze together cost less than a single Shark IZ376H, and between them they cover deep carpet, hard floor, stairs and the car. The single-machine answer is a convenience preference, not a value one.
What we cannot tell you
How long any specific battery will last. Nobody publishes a cycle rating, charge habits vary enormously, and temperature matters. We can tell you which machines let you replace the cell without replacing the vacuum, which is the part you can actually act on.
Common questions
Are corded vacuums more powerful than cordless?+−
On published motor wattage, substantially — 800 to 1,200 W for a corded upright against 181 to 450 W for a cordless stick. Those are consumption figures rather than airflow, so they do not translate directly into cleaning, but the gap is large enough that no cordless machine on this site is recommended for deep pile carpet.
How much does it cost to run a vacuum?+−
Almost nothing. At 18.34 cents per kWh, even a 1,200 W upright run 45 minutes a week costs about $12.87 over three years. The real costs of ownership are filters, bags and — for cordless — the battery.
How long does a cordless vacuum battery last?+−
Nobody in this price band publishes a cycle rating, so an honest answer is not available from the specifications. What is available is which machines have a removable battery: the Shark IZ362H and the Tikom V500 both publish one, which means a fading cell costs you a cell rather than a vacuum.
Is it worth buying both a corded and a cordless vacuum?+−
For a lot of households, yes, and it often costs less than one mid-range cordless. A corded machine for the weekly clean and a very light stick for the two-minute jobs gives each tool the work it is designed for.
Do corded vacuums last longer?+−
They have one fewer component that wears out by design. A cord does not degrade with charge cycles, and washable filters — which most of the corded machines here publish — have no replacement cost either. That is the structural argument, though build quality still varies by machine.
