Dyson V8 Cyclone vs LG CordZero Q3: two cordless vacuums for a small home

Pick the LG if your apartment has rugs or carpet. Pick the Dyson if it's nearly all hard floor and under 700 sq ft (65 m²). That split is my opinion. I haven't used either machine, and the test figures here come from Which?, TechRadar and Tom's Guide.

Abt's listings rate the Dyson at 150 AW and 60 min, and the LG at 150 AW and 60 min. Abt's footnote puts the LG's runtime on the lowest setting without powered tools. I wouldn't choose on those headline numbers. Abt's price for the Dyson is $399 and the LG's list price is $329, checked November 2, 2026.

Measured battery

Which?, the UK consumer group, timed the V8 Cyclone at 43 minutes on minimum power on hard floor and 8 minutes on maximum on carpet. Tom's Guide ran the LG on its highest setting and got about 22 minutes. These come from different outlets and different test floors, so treat the comparison loosely.

Still, 22 against 8 is a wide gap at full power. If you need the top setting for carpet, the LG gets you further. TechRadar's table agrees with Which? on the Dyson, listing 8 minutes in Max.

Both batteries come out. Which? says you can replace the Dyson's yourself, and Tom's Guide lists the LG's as detachable.

Bin and carpet

Here the LG pulls ahead. Tom's Guide lists 0.9 L for the LG, and Which? lists 0.6 L for the Dyson. Abt's listings give 33.8 oz, about 1 L, for the LG and 0.53 L for the Dyson. Tom's Guide says the LG's lever presses the dirt back into the bin, so you empty it less often.

Tom's Guide says the LG senses the floor and adjusts its suction. TechRadar's table says the V8 Cyclone has no auto mode, so you pick Low, Med or Max yourself. TechRadar adds that Low is plenty for hard floors, and it stretches the battery. In an apartment full of laminate, then, that missing sensor costs you little.

Carpet exposes the catches on both. Tom's Guide found the LG's brush dug into a low-pile rug so hard that it had to muscle the vacuum along, though it moved freely on a shag carpet. Which? measured 75 newtons of maximum push force for the Dyson on plush pile, against 23 on medium pile. If you have deep carpet, try to push one in a store first.

Living with each

Weight is close. TechRadar lists the Dyson at 5.7 lb with wand and main head, and Abt lists the LG at 6.28 lb. Neither will decide this for you.

The LG's noise rating is 84 dB on Abt's listing. No comparable figure appears for the Dyson there, so I can't rank them. Thin walls and a sleeping baby? Check that number against your evenings.

Storage is the LG's one real annoyance. Tom's Guide says it isn't free-standing, so it needs a wall mount or a corner to lean in. Measure that spot if you rent and can't drill.

Which home gets which

The LG suits an apartment or small house up to about 1,000 sq ft (93 m²) with rugs, some carpet or a shedding pet. The Dyson suits about 700 sq ft (65 m²) or less, mostly hard floor, cleaned little and often. Over those sizes I'd look at the longer-running machines in my apartment vacuum list, and read why runtime claims slip before trusting any rated number.

I'd skip both for a large carpeted home. The home sizer counts rated runtime, so it may place them higher than I would.
