Shark Detect Pro (IW1120)
The Shark Detect Pro (IW1120) is a $300 cordless stick vacuum built around suction. Shark publishes no airflow or kPa figure, but in Habilytics testing it delivers the strongest pickup of any vacuum under $350 in our rankings, matching machines that cost $400 to $750. A fully sealed HEPA path keeps fine dust from leaking back out. The trade-off is stamina: 40 minutes is the advertised ceiling, and motorized cleaning drains it far faster.

Habilytics Score
Shark publishes no Air Watts or kPa figure for this model, and even if it did, AW and kPa measure different things that can't be compared across brands. Judged on results, it pulls embedded grit from low-pile carpet and hard floors as strongly as machines a full price tier above it, which is one of the best suction outcomes of anything near $300.
Forty minutes is the ceiling, and that number comes from the lowest power setting with a non-motorized tool; clean carpet on Boost and you should expect closer to ten minutes before it dies. There's no swappable battery and no charging dock, so a whole-home session means stopping to recharge from empty.
At 7.5 pounds it sits on the heavy side for a cordless, more than a pound over the LG CordZero (5.9 lb) or Eureka ReactiClean (5.5 lb). It handles floor-level work fine, but the extra weight tells during stairs and overhead reaches, where balance matters as much as suction.

Suction that punches above $300
Shark keeps its airflow numbers to itself, so you won't find an Air Watts or kPa rating on the box, and comparing those figures across brands is unreliable regardless. What matters is the result: in our testing the Detect Pro lifts embedded grit and hair from low-pile carpet as convincingly as the LG CordZero A925 ($400) or Dyson V15 Detect ($750). Pair that with a fully sealed HEPA path, where the exhaust is filtered rather than leaking fine dust back into the room, and you get the two things allergy-prone households value most, at a mid-tier price.
Where it runs out: battery and extras
The 40-minute rating is the best case: lowest suction, non-motorized tool. Clean carpet on Boost and you're realistically looking at around ten minutes before the battery quits, with no spare to swap in and no charging dock to drop it into. That's fine for an apartment or a single floor; it's a genuine problem for a multi-level home, where an LG CordZero (120 minutes rated) simply won't strand you mid-job. The Detect Pro also ships without a mini motorized pet tool, so stairs, upholstery, and car interiors lose the one attachment that makes pet hair easy.
Is $300 the right buy?
You're paying for suction and sealed filtration, not convenience. If your home is small enough that runtime never becomes the bottleneck, the Detect Pro gives you pickup and HEPA sealing that otherwise start around $400, a real saving. But look hard at that $400 tier before you commit: the LG CordZero A925 costs $100 more and answers nearly every one of this Shark's weaknesses at once, with triple the rated runtime, nearly two pounds shaved off (5.9 lb), and a pet tool in the box. For anything larger than an apartment, that hundred dollars is the best money in this comparison.
Who it's for / who it's not
Who it's for
- Apartment and single-floor dwellers whose cleaning sessions finish inside ten to fifteen minutes, so the short runtime never bites
- Allergy-sensitive households that want a fully sealed HEPA exhaust without paying $400-plus for it
- Buyers who prioritize raw carpet and hard-floor pickup over runtime, weight, or a bin-emptying dock
- People with long or shedding hair, thanks to the anti-tangle brush roll on the main floor head
Who it's not for
- Multi-level or large homes: 40 minutes rated (far less on Boost) with no spare battery means recharging mid-clean
- Pet owners who need to clean stairs, upholstery, or the car, since there's no mini motorized pet tool included
- Anyone who does frequent overhead or stair vacuuming, where 7.5 lb becomes tiring fast
- Shoppers who want hands-off emptying or a tidy charging stand, as the Detect Pro has no dock of any kind
Alternatives in our catalog
Tineco Pure ONE Station 5 — $430
Pick the Tineco Pure ONE Station 5 ($430) if hands-off emptying matters more than raw pickup, since its auto-empty base and included pet tool close the Shark's two biggest gaps and it's half a pound lighter, though our scoring rates its suction a step below the Detect Pro's.
