You’ve decided on Shark. Good choice. Now comes the hard part: which one?
Shark’s 2026 cordless lineup has three standout models that all look similar on the surface — cordless, self-cleaning brushroll, LED headlights, 5-year warranty. But once you dig into the details, they serve completely different households.
This guide breaks down the IZ662H (Vertex Pro), IZ377H (PowerPro Plus), and IP3253 (PowerDetect Pet Plus) side-by-side so you can stop guessing and start buying.

The #1 Question: Do You Need an Auto-Empty Base?
This single decision separates the IP3253 from the other two.
If you have a large home (2000+ sq ft) or hate touching dust: the IP3253’s auto-empty docking station is a game-changer. It seals dust away for up to 45 days — you never see it, you never touch it.
If you’re okay emptying the dust cup yourself: the IZ662H and IZ377H save you money and still deliver excellent performance.
That’s the biggest fork in the road. Once you decide on that, the choice between IZ662H and IZ377H comes down to flooring and budget.
Shark IZ662H (Vertex Pro) — Best Overall for Pet Owners
The one that stops the weekly hair-cutting ritual.
The IZ662H is Shark’s mid-range value king. It’s the model most pet owners should start with because it gives you the self-cleaning brushroll at a price that doesn’t hurt.
Key specs:
- 60-minute runtime (ECO mode)
- PowerFins HairPro self-cleaning brushroll — pulls hair directly into the dust cup
- LED headlights
- 5-year warranty
- Converts to handheld for furniture and stairs
Who should buy this:

Shark IZ377H (PowerPro Plus) — Best for Mixed Flooring on a Budget
The one that thinks for you.
The IZ377H gives you the self-cleaning brushroll plus something the IZ662H doesn’t have: FloorDetect smart sensing. This automatically adjusts suction based on the surface you’re cleaning — more power on carpets to pull out embedded dirt, less on hard floors to save battery.
Key specs:
- 50-minute runtime
- FloorDetect auto-adjust suction
- PowerFins HairPro self-cleaning brushroll
- HEPA filtration
- 5-year warranty
Who should buy this:

- Budget-conscious buyers who still want smart features
- Anyone who doesn’t want to think about adjusting suction manually
Price: ~$335

- Auto-empty docking station (seals dust for up to 45 days)
- PowerDetect smart floor sensing
- PowerFins HairPro self-cleaning brushroll
