Our take on the Shark Detect Pro Lift-Away ADV Bagless Vacuum with DuoClean Detect, LA742

The Shark Detect Pro Lift-Away ADV LA742 is a corded upright vacuum with a detachable canister for cleaning stairs, upholstery and above-floor spots. Its DuoClean Detect system pairs two brushrolls with sensors that boost suction and brushroll speed when it finds dirt, when you move forward or backward, near edges and within 2 inches of a wall. A HEPA filter and a headlight round it out. It suits homes with a mix of carpet and hard floor that want strong, automatic cleaning without a cordless battery to manage. Against cordless rivals it never runs out of power, but the cord limits reach and it is heavier to carry up stairs.

About the Shark Detect Pro Lift-Away ADV Bagless Vacuum with DuoClean Detect, LA742

The Shark Detect Pro Lift-Away ADV (LA742) is a bagless, corded electric vacuum for carpets and hard floors. It has a two-brushroll DuoClean Detect system. The system senses hidden dirt, debris and hair, then raises suction and brushroll speed.

Direction Detect senses which way you are vacuuming and sends suction where it is needed, in both forward and reverse. Dirt Detect finds dirt, debris and hair embedded deep in carpets and boosts cleaning power automatically.

Edge Detect raises suction automatically within 2 inches of an edge or wall. This is meant to improve cleaning along edges and corners, and from under baseboards. The vacuum has a HEPA filter and a headlight.

Questions and answers

How is the LA742 different from earlier Shark Detect Pro models?
The ADV version adds the Lift-Away detachable canister, so you can carry the pod to stairs and above-floor spots. The core DuoClean Detect sensor system is the same.
Does it work on hard floors as well as carpet?
Yes. The two brushrolls are designed for both, and the soft roller handles hard floor while the bristle roll agitates carpet.
Do I need to change settings for different floors?
No. The Detect system adjusts suction and brushroll speed automatically based on what it senses, so you mostly just push it.
What comes in the box?
The vacuum, its wand and the Lift-Away canister with the DuoClean Detect floor nozzle. Check the listing for any included attachments such as a crevice or upholstery tool.
Is it good for pet hair?
Yes. The brushrolls and strong suction are built for hair pickup, and the HEPA filter helps keep fine allergens out of the exhaust.
How does it compare with a cordless Shark?
It has more sustained suction and no battery to recharge, but you trade cordless freedom and lighter weight for that power.
