These are feature-based choices, not a performance ranking. Maximum runtimes use different low-power conditions and do not predict a whole-house clean. The two Shark packages are shown deliberately to explain the dock trade-off.
Comparing all 3 products. “Not listed” means the guide does not provide that specification.

Checked 4 October 2026 against Shark US product listing. Standalone vacuum. Accessory stock is not proof of main-unit stock; confirm delivery at checkout.
About the evidence: IP1251 is the standalone package. IP3251 includes a base; no independent head-to-head result is claimed.
Choose this configuration if under-furniture reach matters and you are happy to empty the handheld bin yourself.
Shark lists a folding MultiFLEX wand, twin brushroll head and automatic dirt detection. Its maximum runtime is measured as a hand vacuum in Eco mode, not as a floor-cleaning session.

Checked 4 October 2026 against LG US product listing. Maker provides a retailer finder. Delivery and retailer stock are not confirmed.
About the evidence: This is A923KGMP. Older A916 and All-in-One packages have different equipment; their test results are not used here.
A portable charging stand and telescopic wand suit homes where wall mounting is inconvenient.
LG lists a removable battery, washable cyclone and filters, and a lever that compresses debris inside the bin. The 60-minute claim excludes the powered Dual Floor Max nozzle.

Checked 4 October 2026 against Shark US product listing. Includes the auto-empty base. Confirm the IP3251 package and delivery at checkout.
About the evidence: Compare the complete IP3251 package against standalone IP1251. Paying for a dock is a convenience decision, not evidence of better pickup.
Consider the dock package if emptying after every clean is the chore you most want to reduce. Allow space for the base near an outlet.
Shark identifies IP3251 as its PowerDetect vacuum with a base that charges and empties the cleaner. The base itself still needs emptying and filter care.
