What Makes the Shark PowerPro Plus IZ377H Stand Out?
The real differentiator for the Shark PowerPro Plus is its FloorDetect technology, which senses floor type and self-adjusts brushroll speed. This makes transitions from plush carpets to hardwood floors seamless—no manual switching required.
Hypervelocity suction ensures impressive deep-cleaning even in high-traffic zones, while the HEPA filter traps over 99.97% of allergens, meeting the needs of sensitive users and pet owners.

LED headlights help illuminate hard-to-see debris, while the ability to convert quickly into a handheld vacuum increases versatility for furniture, car interiors, and stairs.

Frequently Asked Questions About the Shark PowerPro Plus IZ377H
