The best cordless vacuum cleaners of 2026

The Shark Stratos IZ862H leads this roundup on a narrow question: whether the maker tells you how its own numbers were measured. Shark ties its filtration claim to ASTM F1977 and its 60-minute runtime to ECO mode at the hand vacuum, and both footnotes sit on the listing where you can read them.

Every figure below is a manufacturer figure, quoted from the surface it appears on: the product title, a numbered feature bullet, the specification table, or the maker A+ block. We ranked these five on how much of the measurement travels with the number, because on this shelf the headline specs are not comparable. Two of these makers state the condition behind their runtime figure and both give the same one, ECO mode measured at the hand vacuum rather than at the floor head. Two attach nothing at all, and Dyson says the V15 figure varies with power mode, dust level, floor type and attachments without saying which of those produced it. This guide is for anyone replacing a corded vacuum in a home with mixed flooring, and for pet owners deciding whether a docked machine is worth the floor space it takes.

Shark

Shark Stratos Cordless Vacuum with Clean Sense IQ IZ862H

9.1/10JellyReviews Score

The Stratos is the machine on this page whose numbers you can check. Shark attaches a named test to the filtration claim, ASTM F1977, and a stated mode to the runtime, ECO at the hand vacuum. It even tells you what the Clean Sense IQ figure is measured against, which turns out to be the same vacuum in its own lowest mode. That is a modest claim published rather than a big one published bare. The listing also states a removable battery and a 5-year limited warranty, against the 2 years Dyson states and the 24 months Tineco states. Amperage is 12.26 A on 25.2 volts, the bin holds 0.72 quarts, and the spec table states a 10-inch cleaning path width.

Pros

The filtration claim carries a named test: over 99.9 percent of dust and allergens, "Based on ASTM F1977 of particles .3 microns and larger"

The 60-minute runtime is published with its condition attached, in ECO mode measured at the hand vacuum

Bullet 8 says the battery is removable and charges anywhere in your home

Shark states a 5-year limited warranty on the listing, against the 2 years Dyson states and the 24 months Tineco states

Cons

The 50 percent better dirt pickup figure is measured against this same machine in its own ECO mode, so it says what Clean Sense IQ adds and nothing about how it compares with another vacuum

Amazon lists the noise level at 80 db, above the 78 db stated for the Tineco and for the Dyson V12 Detect Slim+

Shark

Shark PowerDetect Clean and Empty Cordless Stick Vacuum IP3251

8.8/10JellyReviews Score

This is the most heavily sourced listing in the group. Shark footnotes its suction claim to ASTM F558 and to the geometric mean of ASTM F2607 and IEC 62885-2(5.5), names the mode and the measurement point for both the suction and the 70-minute runtime, and states what the 45-day dock figure covers. Then it does something makers almost never do and names a rival from its own catalog, telling you the DirectionDetect pickup is faster than the Stratos IZ862H. The gap is filtration: the word HEPA appears in the title and the spec table with no percentage anywhere behind it, which leaves the filtration claim a word rather than a measurement. Charge time is 6 hours, against 5.5 for the Tineco and 3.5 for the Stratos.

Pros

Bullet 1 names three test standards behind the suction claim: ASTM F558 at the hand vacuum in Boost mode, and the geometric mean of ASTM F2607 and IEC 62885-2(5.5) against the cordless market

The dock seals debris away for up to 45 days, a figure Shark prints in bullet 3 and again on its own gallery panel

Rated for up to 70 minutes, and the listing says where that was measured: ECO mode at the hand vacuum

Bullet 6 compares this machine directly against the Stratos IZ862H, which is unusual candor about two vacuums the same company sells

Cons

The title says HEPA Filtration and the spec field says HEPA Filter, and neither states a percentage or a particle size, so there is no filtration figure to check

The 18.5-pound figure is the shipped weight of the vacuum plus its base, and the listing publishes no separate footprint for the dock, so there is no stated number for the floor space it takes

FILTRATION FIGURE WITH A FLOOR

Dyson

Dyson V15 Detect Cordless Vacuum Cleaner

8.5/10JellyReviews Score

The V15 has the best single piece of disclosure on this page and the worst internal bookkeeping. Footnote 4 is the reason: Dyson states that the 99.99 percent filtration figure is a Boost mode number and that every other mode still reaches at least 99.97 percent, which tells you the claim is conditional and then tells you the floor. Footnote 1 pins the power claim to the V8 rather than leaving it floating. What drops it two places is that the same page carries two different weights for the same machine, 6.8 pounds in the Amazon field and 7.6 lbs in Dyson's own grid, and the runtime footnote lists the variables instead of naming a mode. Three cleaning modes, a 0.2 gallon bin, 350 watts on 25.2 volts.

Pros

Dyson defines all four of its footnote markers in the product description, so every asterisked claim on the listing resolves to something

Footnote 4 ties the 99.99 percent filtration figure to Boost mode and states a floor of 99.97 percent for the other modes, so the number moves with how you use the machine and Dyson says so

The 100 percent more power claim resolves to a named comparator, the Dyson V8

A piezo sensor counts picked-up particles and the LCD reports the count and the remaining run time as you clean

Cons

The listing states the machine weight twice and disagrees with itself: the Amazon field says 6.8 pounds, and the Dyson comparison grid further down the same page says 7.6 lbs

The runtime figure carries a variance note rather than a measurement condition, so the 60 minutes is not pinned to a mode the way both Shark listings pin theirs

Tineco

Tineco Pure ONE S15 Essentials Cordless Vacuum Cleaner

7.9/10JellyReviews Score

Tineco publishes a filtration number where two of these makers publish none, and then contradicts it twice. The A+ block claims 99.9 percent down to 0.3 microns, which is a real figure with a real particle size, but the spec field above it asserts a HEPA filter and the HEPA standard is defined at 99.97 percent at that size. The second contradiction is sharper: the spec table records one power level while bullet 4 sells iLoop as a sensor that raises and lowers suction on its own. The hardware case is the ZeroTangle roller, which combs hair off the brush rather than letting it wrap, and it is the reason to look at this machine in a house with a shedding dog. Runtime is 40 minutes, charge time 5.5 hours.

Pros

Tineco publishes a filtration figure with a particle size, 99.9 percent down to 0.3 microns, where the Shark PowerDetect and the Dyson V12 Detect Slim+ listings publish no percentage at all

The A+ block says the battery is detachable and replaceable, and bullet 5 says the FreeStnd charging base installs with no drilling

The ZeroTangle roller uses V-shaped bristles and a dual-comb design so hair lifts off the brush instead of wrapping it

Cons

The spec table says Number of Power Levels 1 while bullet 4 says the vacuum adjusts suction automatically, so the listing contradicts itself about its headline feature

The Filter Type field says HEPA Filter while the A+ block claims 99.9 percent at 0.3 microns, which sits below the 99.97 percent the HEPA standard is defined at

The 40-minute runtime is stated with no mode attached, and no test is named behind the 99.9 percent figure

Dyson

Dyson V12 Detect Slim+ Cordless Vacuum Cleaner

7.4/10JellyReviews Score

This is the thinnest listing on the page and that is what places it last, not the machine. Three feature bullets, no manufacturer A+ block, and no footnote markers at all, so the two numbers Dyson does give you float free: 30 percent more power than what, and 60 minutes measured how. The Filter Type field reads Cartridge, and unlike the V15 there is no filtration percentage anywhere to hold it to. What survives is the weight claim, which Dyson makes in its own voice and which the spec table supports at 2.2 kg, and a 3.5-hour charge that is the quickest stated here alongside the Stratos. If the wrist matters more than the paperwork, this is still the Dyson to carry upstairs.

Pros

Dyson calls it the lightest intelligent cordless vacuum it makes, in bullet 1, and Amazon lists the machine at 2.2 kg

Three power levels and a 3.5-hour charge time, matching the Stratos and under the 5.5 hours listed for the Tineco

Cons

The listing carries three bullets, no maker A+ block and no footnotes, so the 30 percent more power claim names no comparator and the 60-minute runtime names no mode

Filter Type reads Cartridge rather than HEPA Filter, and no filtration percentage appears anywhere on the listing

Dyson's own grid on the V15 listing gives the V12 Detect Slim a 0.1 gallon bin where this listing says 0.2 gallons, and the grid names the Slim rather than the Slim+

How to choose the right cordless vacuum cleaner

01What goes wrong with a vacuum, according to the recall record

The CPSC publishes every consumer product recall in the United States, and its database holds 19 recalls of household floor vacuums going back to 1987. Every one of the 19 is an electrical fault or a laceration risk: a power cord whose insulation tears, a plug prong that stays in the socket, a circuit board that sparks, an on-off switch that overheats, a wand that stays energized. Not one of the 19 concerns how well a vacuum cleans. Searching those records for suction or air watts returns nothing, and searching for runtime returns nothing.

The pattern changed with the cordless era, and it changed to the battery. The most recent entry is dated 2 July 2026: Rowenta recalled cordless vacuum cleaners because the lithium-ion battery in the handle can overheat and ignite, on two reports in the United States and 65 more globally. Brookstone recalled a handheld in 2024 for a battery that can short circuit during or after charging, BISSELL recalled a stick vacuum the same year for a battery pack that overheats and smokes, and Electrolux recalled cordless sticks in 2009 for batteries that expand and burst. None of the five machines on this page is recalled. Their brands do appear in the database, for other products: a Dyson bladeless heater in 2014, SharkNinja pressure cookers in 2025, and Shark Rotator upright vacuums in 2015. That is a floor all five clear rather than a reason to rank one above another.

02Why the runtime numbers on this shelf cannot be compared

Both Shark listings state the condition behind their runtime, and the condition is the same: ECO mode, measured at the hand vacuum. That means the lowest power setting with no motorized floor head attached, which is not how anyone vacuums a room. Shark rates the PowerDetect at up to 70 minutes on that basis and the Stratos at up to 60. Dyson attaches a note to the V15 saying actual runtime varies with power mode, dust level, floor type and attachments, which names the variables without naming the measurement. The V12 Detect Slim+ and the Tineco state 60 and 40 minutes with nothing attached at all.

So the useful question is not which number is biggest. It is whether the maker will tell you what the number describes, because a motorized brush roll and a boost setting both draw from the same cell and neither is in the published figure. Charge times are stated more plainly: 3.5 hours for the Stratos and the V12 Detect Slim+, 5.5 for the Tineco, and 6 for the PowerDetect. The V15 field reads 60 minutes, which is identical to its own runtime field and is best treated as a data entry rather than a specification.

03Reading a filtration claim without taking the word HEPA for a number

HEPA is defined as trapping 99.97 percent of particles at 0.3 microns, and 0.3 microns is the size a filter is worst at, which is exactly why the standard is set there. A filter that meets it does better on larger particles, not worse. Three of these five listings put a percentage on the page and two do not, and the three differ: Dyson states 99.99 percent, Shark states over 99.9 percent, and Tineco states 99.9 percent.

The condition is what separates them. Dyson footnote 4 says the 99.99 percent figure is a Boost mode number and that all other modes reach at least 99.97 percent, so you know the claim moves with the setting. Shark cites ASTM F1977 on the Stratos, so you know which test produced it. Tineco names neither a mode nor a test. The Shark PowerDetect title and spec field both say HEPA and put no percentage behind it, and the Dyson V12 Detect Slim+ spec field says Cartridge rather than HEPA at all. Read for the number and the condition together, because the word on its own is a filter class and not a measurement.

§ 04 · FAQ

Questions about cordless vacuum cleaners

Because this page ranks on one thing: how much of the measurement each maker publishes alongside the number. The Dyson V15 carries the single best piece of disclosure in the group, footnote 4, which ties its 99.99 percent filtration figure to Boost mode and states a 99.97 percent floor for the other modes. It loses two places because the same listing states the machine weight as 6.8 pounds in the Amazon field and 7.6 lbs in Dyson's own comparison grid, and because its runtime note lists variables instead of naming a mode. One of those two places is worth naming out loud, because it cuts against this page's own thesis: the tiebreak that separates the V15 from the PowerDetect rewards the listing with fewer figures to disagree with, since the PowerDetect states its weight once and so has nothing to contradict. That is the one place here where publishing less scores better, and it costs the V15 a rank.

None of these five machines is in the CPSC recall database. Their brands are, for other products. Read a brand search carefully if you run one yourself: a plain search for the word Shark also returns Baby Shark bath toys, Quickie Shark wheelchairs and a 1982 fireplace water heater made by an unrelated company called Shark Manufacturing Corporation. The one vacuum recall under either Shark name is from 2015 and covers Shark Rotator upright models NV650W, NV651, NV652 and NV660, over a wand that could stay energized. None of those is a cordless stick. Dyson appears once, for a 2014 bladeless heater, and Tineco does not appear at all.

The recall record says the battery is the part of a cordless vacuum with a safety history, so being able to take it out and replace it matters more than it sounds. The Shark Stratos says in bullet 8 that its battery is removable and charges anywhere in your home. Tineco says in its A+ block that the battery is detachable and replaceable, with spares sold separately. The other three listings do not state whether the battery comes out.

The Tineco Pure ONE S15 Essentials, on the strength of the ZeroTangle roller: V-shaped bristles and a dual-comb design that lift hair off the brush rather than letting it wind around it, so you are not stopping to cut hair away. The Shark Stratos makes a similar case with its self-cleaning brushroll and its DuoClean PowerFins HairPro head, and it ships an anti-allergen brush in the box. The Dyson V15 makes the same case in its bullet 7, which describes the hair screw tool anti-tangle conical brush bar removing long hair and pet hair from pet beds, car seats and stairs.

The verdict

The Shark Stratos IZ862H takes first place because it is the listing that shows its working: a filtration claim tied to ASTM F1977, a runtime tied to ECO mode at the hand vacuum, and a dirt-pickup figure that names what it was measured against. The PowerDetect IP3251 is a close second and cites three test standards on its suction claim, though it publishes no filtration percentage at all. The Dyson V15 Detect holds the best single footnote on the page and loses ground to a listing that states its own weight two different ways. The Tineco Pure ONE S15 Essentials is the pet-hair answer and the machine whose spec table argues with its own bullets. The V12 Detect Slim+ is the machine Dyson calls its lightest intelligent cordless, and the least documented listing here, which is a statement about the listing rather than the vacuum.
