Shark PowerDetect IP1251.
DuoClean Detect nozzle auto-adjusts suction power based on debris concentration, with 70-minute runtime and MultiFLEX storage.

The Verdict.
Gavler Meta-Score
“Shark has done what Shark does best: take the premium features that Dyson pioneered and deliver them at a price that doesn't require justification. The dirt-sensing auto-adjustment genuinely works — you can hear the motor respond as it hits a patch of debris. The MultiFLEX wand is more than a gimmick; it genuinely changes how you clean under furniture. Is it a Dyson? No. Does it need to be? Also no. For most homes, this is more than enough vacuum at half the price.”
