LG CordZero All-in-One A931KWM vs LG CordZero Kompressor Cordless Stick Vacuum with Dual Floor Max Nozzle & ThinQ
Which one to buy
At the same price, the LG with the auto-empty tower is the better value. The LG CordZero All-in-One A931KWM is listed at $600 and includes a tower that empties the bin and charges the battery. The A923KGMP Kompressor stick is listed at $600 and has a plain charger, so you empty its 33.8 oz bin by hand. Both have one battery rated for 60 minutes, Kompressor debris compaction, the Dual Floor Max nozzle, ThinQ app tracking and a handheld mode. The A923KGMP is rated at 220 AW against 210, a gap too small to give up a tower for.
A931KWM owners are enthusiastic about the cleaning, calling the suction unbelievable for a cordless and praising how it handles wool rugs and mixed floors without a nozzle swap. Their complaints are worth reading before you buy, though. At full suction the battery lasts about 14-20 minutes, not the rated hour. The tower often leaves debris stuck around the filter, especially with pet hair, so it's less hands-off than promised. It also uses disposable bags, and some owners report units cutting out after seconds or breaking within about three months.
Owners have said little about the A923KGMP to weigh against that. On paper, though, it shares the same battery and nozzle, so expect similar runtime limits.
Buy the A931KWM at these prices. You get the tower for the same money, and the reliability reports are a reason to keep the receipt and register the warranty, not a reason to buy the model without one.
LG CordZero All-in-One A931KWM
Buy the LG CordZero All-in-One A931KWM at these prices: it costs the same and adds the auto-empty, auto-charge tower.
LG CordZero Kompressor Cordless Stick Vacuum with Dual Floor Max Nozzle & ThinQ
The LG CordZero Kompressor A923KGMP only makes sense if you find it well below the A931KWM's price and specifically don't want a floor-standing tower or tower bags.

LG CordZero All-in-One A931KWM vs LG CordZero Kompressor Cordless Stick Vacuum with Dual Floor Max Nozzle & ThinQ: common questions
Why does the LG A931KWM with a tower cost the same as the A923KGMP without one?▾
At the listed prices, the A931KWM is simply the better deal. Both share a single 60-minute battery, Kompressor compaction and the Dual Floor Max nozzle, and the A923KGMP adds only 10 AW of rated suction while dropping the tower.
How long does the LG A931KWM really run?▾
Owners report about 14-20 minutes at full suction, even though it is rated for 60 minutes at the lowest setting. The A923KGMP uses a single battery with the same rating, so plan around similar limits.
Is the A931KWM's auto-empty tower truly hands-off?▾
Not entirely. Owners say debris, especially pet hair, can get stuck around the filter during emptying and needs clearing by hand, and the tower uses disposable bags that add an ongoing cost.
