Exact Bissell listing: Bissell Pet Hair Eraser DualBrush Upright 42943. Confirm the exact model, configuration, seller, and return terms before ordering.
Quick verdict
Choose the Shark PowerDetect AZ407KT1 if the priority is a feature-rich upright that automatically reacts to floor type, edges, hidden dirt, and cleaning direction.
Choose the Bissell Pet Hair Eraser DualBrush 42943 if the priority is a pet-focused package with a detachable Lift-Off pod, a 1.25-liter bin, FurFinder headlights, an LED TurboBrush tool, and a currently visible replacement-parts path.
This page compares two current, exact models. It no longer treats every Shark and Bissell vacuum as if the brand names describe one product.
If an upright is not yet the settled format, start with the broader Bissell-versus-Shark cleaner-type guide before comparing these two packages.
| Decision factor | Shark PowerDetect AZ407KT1 | Bissell Pet Hair Eraser 42943 |
|---|---|---|
| Main design | Sensor-driven DuoClean upright | DualBrush pet upright with detachable pod |
| Floor response | Dirt, edge, floor, and direction detection | Dual brushes plus swivel head |
| Above-floor path | Hose and bundle tools | Lift-Off pod, 7-foot hose, lit tools |
| Bin | Confirm exact current package | 1.25 L |
| Listed weight | Confirm on exact bundle | 17 lb |
| Filtration claim | Anti-Allergen Complete Seal, 99.99% at 0.3 microns or larger under stated test | HEPA sealed system, 99.97% at 0.3 microns under stated test |
| Cord | Confirm exact bundle | 30 ft |
Percent claims are not directly interchangeable when test language differs. Treat both as sealed-filtration features that still depend on fitted, maintained filters.
Where Shark earns its premium
PowerDetect uses sensors to change behavior around hidden dirt, floor transitions, edges, and reverse passes. That can reduce manual mode changes in a mixed-floor home. The DuoClean Detect head uses two brush rolls and Shark’s no-hair-wrap design.
The AZ407KT1 is a specific bundle with an under-appliance wand, pet multi-tool, crevice tool, odor cartridge, and additional cleaning tools. Another PowerDetect code may contain a different package, so compare the suffix as carefully as the machine name.
Where Bissell makes the stronger case
Bissell’s 42943 has a clear pet-home package: two brush rolls, FurFinder headlights, a detachable pod, a 7-foot hose, 1.25-liter bin, LED TurboBrush, and a lit crevice/dusting tool. Bissell lists a 30-foot cord and 17-pound weight.
The Lift-Off pod matters for carpeted stairs and upholstery because the owner does not have to balance the full upright on every step. It does not turn the machine into a lightweight handheld; the hose, pod, and powered tool still need a practical carrying plan.
Carpet, hard floors, and edge work
Shark is the stronger starting point for buyers who want the machine to react automatically as conditions change. Bissell is the more explicit pet-tool package and publishes a 9.8-inch cleaning path, which can maneuver through tighter areas but covers less width per straight pass than a broad head.
Neither feature list proves compatibility with every rug. Check brush and suction guidance for delicate, high-pile, fringed, or hand-knotted rugs. For sealed hard floors, use the manufacturer’s intended floor mode and inspect the head for trapped grit before a pass.
Maintenance and parts
Both machines need hair removal checks, filter care, bin emptying, hose inspection, and periodic tool cleaning. Bissell currently lists brush rolls, belts, filters, tank parts, hose parts, and tool components for the 42943, although some are marked available soon. Shark provides a support path for the PowerDetect family; verify replacement filter, brush, hose, and odor-cartridge availability for the exact code.
Odor cartridges are optional value, not a cleaning requirement. Include their repeat cost only if that feature matters to the household.
Who should skip both
Skip both if 17-pound-class upright handling is unsuitable, storage is very tight, or most cleaning happens on stairs. A lighter cordless stick may be used more often even if its bin and runtime are smaller. Choose a bagged vacuum instead if dust containment during emptying is more important than bagless convenience.
Verdict
The Shark PowerDetect AZ407KT1 is the feature-first choice for automatic adjustment and a premium current upright bundle. The Bissell Pet Hair Eraser DualBrush 42943 is the pet-tool and detachable-pod choice with a large published bin and transparent current parts catalog.
