Shark PowerDetect Clean & Empty (IA3241)
The Shark PowerDetect Clean & Empty is a mid-priced ($470) cordless that pairs some of the strongest tested suction in our catalog with a self-emptying dock, so you rarely touch the dust bin. That combination is its whole argument: Shark-grade pickup plus hands-free emptying for less than LG's auto-empty flagship. The catch is weight. At 8.6 lb it's the second-heaviest vacuum here, and its 60-minute runtime is an eco-mode figure that collapses on Boost.

PowerDetect Clean & Empty (IA3241)
Auto-empty dock and top-tier carpet cleaning at half Dyson money
Typical price
$470
Strengths
- high-end Suction (8/10)
Worth considering
- below-average Handling (3/10) — 8.6 lb
- below-average Runtime (4/10) — 60 min
Habilytics Score
Shark publishes no Air Watt or kPa rating for the PowerDetect, so it can't be ranked numerically against Dyson (AW) or the kPa brands - and those two units aren't comparable to each other regardless. The strong mark reflects tested pickup, which lands near the top of this catalog on both carpet and bare floors.
The 60-minute rating is a best case: eco mode paired with a non-motorized tool. Switch to the powered brush on Boost - where this vacuum's suction actually lives - and realistic cleaning time falls to roughly ten minutes, mid-pack at most.
At 8.6 lb this is the second-heaviest cordless in our lineup, behind only Shark's own Stratos. You feel every ounce overhead and on stairs, where the high-set weight turns short jobs into a wrist workout well before the battery gives out.

The draw: strong suction you never have to empty by hand
The PowerDetect's case rests on two things working together. Its tested suction is among the best here, close behind Dyson's flagships and level with Shark's own Stratos, so it pulls embedded pet hair and grit out of carpet that weaker units skim over. The Clean & Empty dock then voids the onboard bin automatically each time you park it - which matters more than it sounds, because emptying is the one chore most cordless owners skip, and skipping it is what slowly chokes suction. Few vacuums under $500 deliver both at once.
The trade-off: it's heavy, and 60 minutes is fiction on Boost
All that power ships in an 8.6 lb body, and only the Stratos weighs more. On floors the heft is manageable; lifted overhead for cobwebs or carried up a staircase, it fatigues your wrist fast, which is why handling sits near the bottom of our catalog. Runtime compounds the problem. The advertised 60 minutes is eco mode with a non-motorized tool; put the powered brush on Boost and you are realistically near ten minutes before docking. For a large home cleaned in one pass, that is a genuine constraint, not a footnote.
Value at $470: you're paying for the dock, not the endurance
At $470 the PowerDetect sits below LG's $600 A937 - the only other auto-empty unit here that also fixes weight and runtime. That gap is the honest framing: pay $470 for Shark suction and hands-free emptying, or $130 more for the A937 and add a 120-minute rating and a 6 lb body on top of the same dock. If you clean mostly one floor and value raw pickup, the PowerDetect earns its price. If stairs or long sessions are in play, the money is better spent elsewhere in this catalog.
Who it's for / who it's not
Who it's for
- You want strong carpet and pet-hair pickup and would rather trust tested performance than compare spec sheets - Shark publishes no suction number, but this scores near the top here.
- You hate emptying the bin: the auto-empty dock handles it every time you dock the wand.
- Your cleaning is mostly single-floor, so the 8.6 lb weight rarely has to leave the ground.
- You want auto-empty convenience without paying LG A937 ($600) money.
Who it's not for
- You clean stairs or hold the wand overhead often - at 8.6 lb this is the second-heaviest cordless here and tiring to handle.
- You need longer sessions: real Boost-mode runtime is closer to ten minutes than the advertised sixty.
- You want the lightest, longest-running option near this price - the LG A925 ($400) is 5.9 lb with a 120-minute rating.
- You expect a published suction figure to compare against Dyson (AW) or the kPa brands; Shark discloses none.
Alternatives in our catalog
LG CordZero A937 Auto-Empty — $600
Pick the A937 if you want the same auto-empty dock but far better handling and endurance - 6 lb and a 120-minute rating - and can absorb the jump to $600.
Head-to-head comparisonShark Stratos Cordless (IZ862H) — $430
Pick the Stratos if you want the same Shark-grade suction for $40 less and don't need the auto-empty dock, accepting that at 8.9 lb it handles even worse.
