Shark NV356E vs NV501 Reviews: Which One Wins?

With a shedding dog and a house split between dark hardwood and thick area rugs, I needed to see which of these Sharks could actually keep up. I pulled both vacuums out and put them to work in my living room to test their limits.

How They Handle Thick Carpet

The NV356E has a noticeable mechanical hum, sending a strong vibration straight through the handle on my thick rug. While the NV501 sounded quieter, pushing it across plush carpet demanded significantly more effort because of its intense suction seal. Fortunately, twisting open the Suction Release collar on the handle helped bleed off some pressure, making it much easier to push. Warm exhaust air kept brushing against my legs as I worked around the coffee table, a quirk that became quite noticeable after several minutes of vacuuming.

Steering and Maneuverability

Getting around furniture took more work with the NV356E. I had to put a little more into each turn. The NV501 felt different right away. Chairs and table legs were easier to get around without constantly correcting the nozzle.

Cleaning Dark Floors: What the LED Headlights Reveal

Using the NV356E felt like flying blind on dark hallways, but its secret weapon is the Dust-Away hard floor attachment with dry microfiber pads, which traps fine dust and leaves bare wood looking polished. Meanwhile, the NV501 lacks this specific attachment, relying solely on its ultra-bright LED headlights to spot hidden pet hair and fine dust across dark wood floorboards.

Cleaning Under the Bed

To avoid moving a heavy bed frame, testing the Lift-Away feature was a priority. Popping the pods off the main wand was intuitive, allowing for deep reaches under furniture without excessive bending. Suction remained consistent with both models, easily capturing the hidden dust bunnies. However, dragging the detached pods around the bed frame legs still required some awkward maneuvering.

Cleaning Stairs

The NV356E is notoriously top-heavy on stairs. The canister required constant babysitting because it tended to shift backward. The stiff hose didn’t help either, acting like a spring that constantly threatened to pull the whole unit over, leaving my forearm tired pretty quickly.

Despite being heavier overall, the NV501’s squat, wide design provided a solid anchor on my 11-inch wooden stairs. This stability allowed me to actually focus on cleaning instead of just holding the vacuum steady, meaning my shoulders were far less taxed by the time I reached the bottom.

Above-Floor Cleaning: Hose Reach and Stability

The NV356E’s stiff hose made the canister prone to tipping when reaching for higher spots. In contrast, the NV501’s hose felt much more flexible, making overhead tasks practically effortless. Reaching the curtains and high room corners was a breeze while the NV501’s wider base stayed firmly planted on the floor.

Brushroll Performance & Edge Cleaning

When tracking along the baseboards, the NV356E picked up dog hair flush against the wall, practically eliminating the need for a crevice tool. The NV501, on the other hand, left a narrow strip of dust by the molding, requiring a second pass.

As for the brushrolls themselves, neither model is completely tangle-free. After a few weeks of heavy pet hair duty, long strands started winding tightly around both rollers, eventually forcing a sit-down session with scissors to cut the mess loose.

Dust Cup: What Annoyed Me Most

Emptying the dust cup is always the most dreaded chore with bagless models. The second the bottom door swings open over the trash bin, a puff of fine dust hits the air. Pet hair also tends to get statically glued around the inner metal screen on both units, requiring an annoying manual pull to clear it out.

Capacity is where these two really diverge. The NV501’s bin hits its 0.88-quart ‘Max Fill’ line surprisingly fast, especially with pet hair on plush carpet. The NV356E, however, boasts a massive 2.2-quart capacity, allowing for much longer cleaning sessions before forcing a trip to the garbage.

NV356E vs NV501: Which One Should You Buy?

If you have mostly bare floors (hardwood/tile) and thick carpets with lots of pet hair, I’d choose the NV356E. The 2.2-quart dust cup holds a massive amount before emptying, and the Dust-Away attachment is unmatched for cleaning bare floors. Its lighter body also helps during longer cleaning sessions. Stairs are where it feels less convenient. I’d lean toward the NV501 if you have a mix of low-pile rugs, dark hallways requiring LED illumination, and several stairs. It takes more effort on plush rugs, and the smaller bin needs more frequent emptying. Still, its squat design and wider base made it feel remarkably stable on the stairs.
