LG vs Shark
On the numbers, Shark fields the deeper lineup (37 models), while Shark has the cheaper entry point at ~$74, while Shark leans harder into mopping (9 mopping machines). The table has the lineup-level numbers; the matchups below put individual models spec sheet to spec sheet.
Which brand to buy
Shark's cheapest self-emptying stick now costs $500; LG's cheapest costs $600. That gap, plus a 5-year warranty on Shark's sticks against 1 year on LG's, frames this comparison. Both make cordless sticks with docks, but Shark also sells uprights, corded sticks, handhelds, robots and a floor washer, while LG sells only CordZero sticks.
At the self-emptying tier the pairing is the Shark PowerDetect Clean & Empty at $549 against the LG CordZero All-in-One A931KWM at $600. Shark owners in heavy-shedding homes report going nearly two years without detangling the brushroll and touching the bin about once a month; the knocks are a bulky, top-heavy body and runtime that shrinks once the sensors boost. A931KWM owners praise its suction on rugs and mixed floors, but report 14 to 20 minutes at full power and debris snagging in the dock. The cheaper Shark Detect Pro Auto-Empty System, at $250, was light and easy on stairs, though owners say its dock was reportedly covered for only 90 days and some failed within months; it is now discontinued, replaced by the Shark PowerDetect Speed Clean & Empty System at $500.
LG pulls ahead on runtime at the top. The LG CordZero All-in-One A949KTMS at $1,000 keeps a second battery charging in its tower, and owners say runtime anxiety disappears. Owners of several Shark sticks, including the now-discontinued Shark Stratos Cordless and Shark Vertex Pro Cordless Stick Vacuum, describe battery life falling well short once power goes up.
Buy Shark for pet hair, the longer warranty and a self-emptying stick for less than LG charges. Start with LG if you have a large home, want two batteries and a tower that hides everything, and can live with the shorter warranty.

LG vs Shark: common questions
Shark PowerDetect Clean & Empty or LG CordZero All-in-One A931KWM?▾
They cost $549 and $600. Shark owners with heavy shedders report little brushroll maintenance and rare bin emptying, while LG owners praise suction but report short full-power runtime and some clogging in the dock. The Shark also carries a 5-year warranty against LG's 1 year.
Which has the better warranty on stick vacuums, Shark or LG?▾
Shark's cordless sticks carry 5 years, while LG's carry 1 year, with the LG CordZero All-in-One A931KWM adding a 10-year motor warranty on parts. Owners of the now-discontinued Shark Detect Pro Auto-Empty System said its dock had much shorter coverage than the vacuum, so check dock coverage on any Shark.
