Dyson Gen5detect vs LG CordZero All-in-One Tower Cordless Stick Vacuum with Auto Empty & Kompressor
Quick take: The LG CordZero All-in-One Tower Cordless Stick Vacuum with Auto Empty & Kompressor costs $117 less; the LG CordZero All-in-One Tower Cordless Stick Vacuum with Auto Empty & Kompressor runs longer per charge (120 vs 70 min).
Which one to buy
Emptying the bin is the question here. The LG CordZero All-in-One Tower empties itself every time you dock it, and the Dyson Gen5detect does not; Dyson makes no self-empty dock for its sticks at all. With only $16 between them, that one feature decides it for most households, especially pet homes where a 0.77 L Dyson bin fills mid-clean and puffs dust when you dump it.
The LG adds more on top. It is lighter at 5.95 lbs against 7.6, it ships with two quick-release batteries for a rated 120 minutes, and reviewers measured a 3.5-hour recharge against the Dyson's roughly 4.5. Its power button latches, so neither machine makes you hold a trigger. It also has app control, which the Dyson lacks.
The Dyson's case is filtration and suction. It is sealed with HEPA throughout, which allergy-household owners single out for less dust smell during and after cleaning, while the LG lists a 5-step filtration system. It is rated at 280 AW in Boost to the LG's 210 AW, and owners say that pulls grit out of carpet older vacuums left behind. The laser and particle counter show you what you are picking up. It also carries a 2-year warranty against the LG's 1.
The LG's costs are ongoing and physical: proprietary dock bags and filters, an 84 dB rating with a loud extraction cycle, and a tower over 3 feet tall that needs a permanent spot. Dyson owners, for their part, report scratched plastic, a broken head wheel and battery failures near the 2-year mark.
Dyson Gen5detect
Go this way if someone in your home has allergies, you clean a lot of carpet, and you prefer a longer warranty and no bag costs over auto-emptying.

Dyson Gen5detect vs LG CordZero All-in-One Tower Cordless Stick Vacuum with Auto Empty & Kompressor: common questions
Is the LG's auto-empty tower worth giving up the Dyson's HEPA sealing?▾
For pet households that empty a bin daily, often yes, because the tower means you rarely touch the dust. For allergy households, the Dyson's whole-machine HEPA seal is the stronger case, and its owners specifically report less dust smell during and after vacuuming.
Does the LG need replacement bags?▾
Yes. The tower uses LG's proprietary bags, plus HEPA and exhaust filter replacements over time. The Gen5detect has a washable filter and no bags, so its running cost is close to zero outside of a replacement battery.
Which one has the longer runtime?▾
The LG ships with two batteries for a rated 120 minutes and reviewers measured a 3.5-hour recharge. The Gen5detect is rated at 70 minutes on one pack with about a 4.5-hour recharge, and owners say Boost drains it in well under 15 minutes.
