Dyson V8 vs V12 Detect Slim: is the laser worth twice the price for an apartment?

The V8 is Dyson's entry stick: 5.6 lb, up to 40 minutes, a five-hour charge, no screen. The V12 Detect Slim is lighter at 5.2 lb, runs up to 60 minutes, charges in four, and adds a laser on the hard-floor head and a dust-counting display — at roughly twice the price. For a hard-floor apartment the V12 is the better vacuum; whether it is twice as good is the question.

Weights, run times and charge times are from Dyson’s own pages and are for the stick without accessories. The V12’s laser and display are listing details, marked pending. Suction figures are not compared because Dyson’s pages for these models do not state them in air watts; the V8’s 115 AW on the listing is a retailer figure.

The V8 is the Dyson without the extras: a 5.6 lb stick that runs up to 40 minutes on the lower setting, charges in five hours, has a 0.14-gallon bin and two power modes, converts to a handheld, and has no screen, no sensor and no laser. It has been in production long enough that spare batteries, filters and heads are easy to find.

Strengths

  • 5.6 lb, the lightest full-size stick here
  • Converts to a handheld for stairs and the car
  • Dyson's own run-time figure, not a marketing maximum

Limitations

  • 40 minutes is on low power; high is far shorter
  • Five-hour charge, the slowest in the group
  • No floor sensor or display

Good for

  • an apartment with mostly hard floors
  • a vacuum that lives in a hall closet
  • someone who wants Dyson without the V12/V15 price

Look elsewhere if

  • thick carpet throughout
  • an hour of cleaning on one charge

The V12 Detect Slim is 5.2 lb and runs up to 60 minutes, charges in four hours, and carries a slim fluffy head with a laser that lights up dust on hard floors and a piezo sensor that counts particles on a screen. The Origin trim here ships with fewer tools than the Absolute. It costs roughly twice the V8.

Strengths

  • 5.2 lb and a slim head that turns under furniture
  • Up to 60 minutes, by Dyson's figure
  • Laser shows dust on hard floors you would otherwise miss

Limitations

  • Origin trim ships with fewer tools than Absolute
  • Small bin on a slim machine
  • Costs roughly twice the V8

Good for

  • hard floors in an apartment
  • anyone who finds dust reassuring to count
  • a cleaner who wants the lightest Dyson

Look elsewhere if

  • deep carpet
  • a tight budget

Weight and reach

The V12 is 0.4 lb lighter and noticeably slimmer; its head turns under a sofa where the V8’s does not. Both are one-hand machines on the stairs. If the apartment has a lot of low furniture, the V12’s head earns its keep.

Run time and charge

Sixty minutes against forty, both on low power; on high, both drop to a fraction of that, and Dyson does not publish the high-power figure for either. For an apartment of 900 square feet on a medium setting, both finish with charge to spare. The V12’s four-hour charge against the V8’s five matters only if you clean twice in a day.

The laser and the screen

On a hard floor in daylight you miss fine dust; the V12’s laser shows it, which is either reassuring or compulsive depending on the household. The screen counts particles by size and tells you when the floor is clean, which some people find motivating. Neither feature does anything on carpet, and the laser is on the hard-floor head only.

Price

The V12 is roughly twice the V8. The difference buys 0.4 lb, 20 minutes on low, an hour off the charge, a slimmer head, the laser and the screen. Whether that is worth it depends on how much the dust you cannot see bothers you.

Which one, by apartment

  • Hard floors, under 900 square feet, a budget: V8.
  • Hard floors, low furniture, and you want to see the dust: V12 Detect Slim.
  • Carpet throughout: neither; a Shark PowerDetect with the 0.7-quart cup.
  • A pet: neither bin is big enough; see the apartment shortlist.

Is the V12 really lighter than the V8?

By Dyson's figures, yes: 5.2 lb against 5.6. The V12 is also slimmer, with a narrower head that turns under furniture. Both figures are for the stick without accessories, which is how Dyson weighs its machines.

What does the laser do?

It shines a green light across a hard floor at a low angle so dust you would not otherwise see shows up ahead of the head. It is on the slim fluffy head, which is a hard-floor head; on carpet it does nothing. The piezo sensor counts particles and shows them on the screen. Both features are on the listing, which Dyson's spec table does not spell out, so they are marked pending.

Which has the bigger bin?

Dyson gives the V8 a 0.14-gallon bin on its page; the V12's bin is small for a slim machine and Dyson's page does not give a comparable figure. Neither is a pet-household bin; both fill in a room with a shedding dog.

Which should I buy on a budget?

The V8. It does the same hard-floor apartment on a lower setting in 40 minutes, converts to a handheld, and the parts have been made longer than any other Dyson's. The V12 is the better vacuum; the V8 is the better value.

Best cordless stick vacuums for an apartment: six from 5.2 to 8.1 pounds, on the makers' own run times

In an apartment a cordless stick is the only vacuum: light enough for a flight of stairs, small enough for a closet, and able to do 900 square feet on one charge — while makers quote run time in the mode you will never use. Six sticks from Dyson, Shark, Samsung, Bissell and Eureka, compared on weight, run time per mode, charge, bin and warranty as the makers publish them.

How to choose a cordless vacuum: run time by mode, weight, bins and where it lives

Cordless vacuums are sold on a minutes figure measured in the mode you will not use, a suction figure most makers do not publish, and a weight that may or may not include the head. This guide explains which numbers to read, what they mean for an apartment or a house, and what the makers who publish honest figures say — with four machines as worked examples.
