Cordless and stick vacuums, judged on what you actually get

Start here: buy the bin, not the runtime

Almost every cordless vacuum in this price band publishes the same headline: forty minutes. Shark's IX141, IY143H, IZ362H and IZ376H all say 40. Bissell's PowerClean 4173 says 40. The Dyson V8, which costs several times as much, also says 40. If runtime is the number you are shopping on, you are shopping on a number that does not separate these machines at all.

What does separate them is dust cup capacity, and it varies by a factor of nearly four across machines with identical runtime claims. The Shark IX141 holds 0.34 quarts. The IZ376H holds 0.79. The Tikom V500 holds 1.3 liters. In practice that is the difference between stopping three times to empty during one clean and stopping once — and the interruption people actually complain about after a month of ownership is emptying, not charging.

How the category divides

There are really three machines being sold under one label. Lightweight hard-floor sticks (the Vacmaster VSD1001 at 4.4 lb, the Eureka Blaze at 2.8 lb corded) are for crumbs, stairs and cars — they have little or no brushroll agitation and will disappoint on pile. Full-size cordless sticks (Shark, Levoit, Tineco, Bissell, Tikom) are the mainstream buy: 5 to 8 lb, a driven brushroll, and enough battery for a floor or two. Corded uprights and canisters (Shark's NV356E, Bissell's CleanView line, Eureka's PowerSpeed) still exist for a reason, and it is the reason the rest of this site keeps coming back to: they have no battery to replace.

That last point is the whole cost argument. A cordless vacuum's battery is a consumable with a finite cycle life, and most manufacturers in this band do not publish a cycle rating at all. When the cell fades, a machine with a removable battery — the Shark IZ362H, the Tikom V500 — can be revived for the price of a cell. A machine with a sealed battery becomes landfill. That single spec is worth more over five years than any suction figure on the box.

What actually decides the price

The pattern is consistent: the money above about $150 buys durability, filtration and hair management — not minutes and not, as far as anyone publishes, suction. Dyson's V11 Origin is the only machine on this site that publishes a figure in air watts (185 AW), a unit you can actually compare. Everyone else publishes pascals, or motor wattage, or nothing at all, and none of those tell you what reaches the floor.

The mistake buyers make

They buy on the pascal number. A listing shouting 55,000 Pa looks like it must out-clean one claiming 40,000. But pascals measure sealed static pressure at the motor inlet, brands measure it differently, and none of them publish their method — so the figure is not comparable between manufacturers and barely comparable within one. A 450 W Tikom motor and a 181 W Shark motor are not four times apart in cleaning; they are measured differently.

The second mistake is buying a heavy machine for a job that is mostly above the floor. If your real complaint is stairs, upholstery and the car, a 7.9 lb stick with a big bin is the wrong answer and a 4.4 lb machine or a canister is the right one. Read the weight before the suction claim.

Where to go next

If you want the shortest path to a decision, start with the budget cordless roundup — it ranks the mainstream picks with live prices. If your floors are wood, the hardwood roundup is the more specific answer; if they are carpeted, the carpet roundup is, because carpet is the one surface where a driven brushroll decides everything. If the house is half of each, the hardwood-and-carpet roundup covers the machines that publish a way to switch between them. If somebody reacts to dust, the allergy roundup ranks on which brands name a filtration test standard; the stairs roundup solves the job every upright is worst at; the apartment roundup leads on the decibel rating nobody shops on; and the long-hair roundup covers the machines that publish an anti-tangle brushroll. Choosing between the two brands on this shelf is Shark versus Bissell, and Bissell versus Dyson runs the same test against the flagship. Four close reads of specific machines sit here too: the Shark Navigator review, the Bissell CrossWave review, the Tineco A30S review, which takes apart the most complete spec sheet on this shelf and the four figures Tineco leaves off it, and the Eureka Whirlwind review, which explains why one cheap bagless canister wins eight of our rankings and why it never wins a carpet page. For carpet deep enough that the head seals to it, shag carpet ranks on height adjustment; for a beach house, sand treats filtration as a durability question rather than an allergy one. If the mess is crumbs rather than dust, floor sweepers and electric brooms covers the lighter machines that sit between a broom and a vacuum - and explains which of them have no suction at all. Three more specific answers were added in September 2026: corded stick vacuums for the stick shape without a battery, tile floors where a brushroll scatters more than it collects, area rugs where it can damage a fringe, and cat litter, which is heavy grit and fine clay dust at once. Choosing between Shark own two upright lines is Navigator versus Rotator. If somebody in the house reacts to dust, the bagged roundup ranks the uprights and canisters that seal the dust in a bag, and says which of them back that up with a filtration figure. If the messes are counters, stairs and the couch rather than floors, the handheld roundup ranks the hand vacs on charge time against runtime and on whether the pet tool actually turns. If the vehicle is the problem rather than the house, the car vacuum roundup covers the hand vacs, 12-volt machines and small wet/dry vacuums that fit a car interior. If you would rather pull a machine behind you than push one, the canister roundup ranks the shape that keeps its weight on the floor — and names the only one of them with a motor in the floor tool. If the hard floors need washing as well as vacuuming, the wet/dry vacuum mop roundup ranks the cordless floor washers that do both in one pass. If you are trying to decide whether to go cordless at all, cordless versus corded does that arithmetic in full, and our method explains exactly what we can and cannot tell you from a spec sheet. Four pages were added in October 2026: how to choose a vacuum runs the whole decision as five questions in order; can you vacuum up water answers the question people ask with a puddle already on the floor, and names the machine class for each kind of water; Shark HydroVac versus Bissell CrossWave settles the two floor washers buyers get stuck between; Tineco versus Shark compares the two brands on what each one publishes rather than on suction claims neither explains; the Levoit Anti-Tangle review reads the only machine here that states runtime three ways; and the best vacuums for seniors ranks on carried weight, push effort and trip hazard rather than on suction.
