Pros & cons
LG CordZero All-in-One A931KWM
- ✓Auto-empty, auto-charge tower for meaningfully less than LG's flagship A949KTMS
- ✓Kompressor tech compacts debris so the small bin needs emptying less often
- ✓Dual Floor Max nozzle handles carpet and hard floors without swapping heads
- ✓ThinQ app tracks battery health, filter status, and runs diagnostics
- ✓Washable, removable filters keep ongoing filter costs low
- ✓LED headlight and telescoping wand for reach and visibility
- ✓Real street price (~$400) undercuts the $599.99 list price substantially
- ✗Single battery caps runtime at about an hour, less in Power/Turbo mode
- ✗Long-term owners report mixed cleaning performance, including units that cut out after seconds of runtime
- ✗Multiple owners report the vacuum breaking within roughly three months of normal use
- ✗Auto-empty tower reliability is inconsistent — works well for some, stops working reliably for others
- ✗Tower disposal uses proprietary bags, not a simple bagless bin — a recurring cost
- ✗No mop attachment or second battery — those are reserved for the pricier A949KTMS
