Shark PowerPro Pet Cordless Stick Vacuum IZ373H

Shark uses the PowerPro name on more than one cordless stick, and the IZ373H is the lighter of the two covered here: 7.03 lb (3.19 kg), against 9.33 lb (4.23 kg) for the PowerPro Flex Reveal Plus IZ382H. This page is about the PowerPro Pet, model IZ373H, a dockless Shark PowerPro stick vacuum with a 21.6 V battery rated for up to 50 minutes at the handvac in standard mode, a 0.8 qt bagless bin and a self-cleaning PowerFins nozzle.

Which Shark PowerPro is the IZ373H?

The IZ373H is the PowerPro Pet. It is a different machine from the Flex Reveal Plus IZ382H, which Shark sells with Dirt-Reveal lighting and a bendable wand. The gap is 9.33 lb (4.23 kg) against 7.03 lb (3.19 kg), and that matters when you carry the stick up stairs. Even so, 7.03 lb (3.19 kg) is a touch above the 6.8 lb (3.1 kg) catalogue median for sticks, so the IZ373H is lighter than its sibling, not light for a stick. If a listing says only PowerPro, find the model number before comparing anything else.

Shark does not publish suction power in watts, noise level or battery capacity. The 181 W on its page is power input, not a cleaning measure.

Nozzle, filters and what they do

The PowerFins nozzle is self-cleaning, which Shark describes as having no hair wrap. FloorDetect adjusts brushroll speed to the floor type, so the same head works on carpet and hard floors. LED headlights help you see under furniture, and the stick converts to a handheld for stairs and upholstery.

Shark lists an Anti-Allergen Complete Seal and a HEPA filter after the motor, which it says captures over 99.97% of dust and allergens at 0.3 microns and larger under ASTM F1977. That is the manufacturer's claim, not independent testing. Before the motor are a washable foam filter and a felt filter. Rinsing the foam is part of upkeep, and Shark's page gives no replacement interval for the filters, so follow the manual.

What the specs point to

• A HEPA filter. The IZ373H suits households that want a HEPA filter. Shark lists HEPA filtration and designs the Complete Seal to keep dust in the system.
• Pet hair and mixed floors. The box holds a pet multi-tool and the nozzle is tangle-resistant, though without a suction rating this rests on listed features only.
• Warranty length. A warranty of 5 years ranks in the top quarter among stick vacuums in our catalogue, where the median is 2 years. Shark's page notes only 2 years on parts, so read the terms.
• Bin size. At 0.8 qt, the cup is bigger than the 0.5 qt on the PowerDetect Speed IA1241 and the 0.3 qt on the IX141.

Our cordless vacuums category page shows how sticks compare on runtime, weight and bin size.

Drawbacks and missing details

• No dock. You empty the cup by hand.
• Runtime is a best case. Fifty minutes is measured at the handvac in standard mode. Shark gives no lower figure, so expect less with the floor nozzle on carpet.
• Charge time is not listed, which makes it hard to plan around recharging.
• One battery. Shark's page lists a single battery, whereas the Flex Reveal Plus is sold in a version with a second battery.
• Upholstery tool is not in the box. Shark sells it separately.
• Unpublished specs. Suction, noise and battery capacity are missing, so performance comparisons are limited to what Shark states.

Shark IZ373H to buy: checking the right PowerPro

Shark uses the PowerPro name on more than one stick, so a listing that says only PowerPro could be a different machine. The IZ373H is the PowerPro Pet, the lighter sibling of the Flex Reveal Plus IZ382H, so look for the full model code before you compare offers.

Check what comes with it. Shark lists a straight wand, a crevice tool and a pet multi-tool, and this model has no dock, so a listing that shows one is describing something else. The five-year limited warranty is Shark's, and its page notes only two years on parts, so read the terms for the listing you choose.

The prices below refresh as retailers change them. Use it to compare IZ373H prices on equal terms: same model code, same box contents, same battery count. Offers can run up and the lower entries are worth a second look to see what is missing. Matching the code and the contents first is a better way to judge a listing than the headline figure.

Other Shark sticks to compare

If you want a second battery and can accept more weight, look at the PowerPro Flex Reveal Plus models. If you want floor and dirt sensing, the PowerDetect Speed IA1241 lists up to 60 minutes in ECO mode with a non-motorized tool and a 6-hour charge. The wider Shark family range covers the rest.

Once the specs fit, the prices section below lists current offers for the IZ373H. Confirm the model number and condition before you compare totals.

If you would rather hand floor care to a robot, the Shark Stratos robot vacuum page covers a mapping robot with an emptying base. A side-by-side look at this stick and a Dyson model is in our Dyson versus Shark PowerPro comparison.

A corded alternative is covered on the Shark Detect and Reveal corded stick page.
