Compare Simplicity Vacuums Allergy Upright Vacuum, S20EZM vs Shark Rotator Powered Lift-Away Upright Vacuum, NV752

Ease of use is mostly positive, though physical effort and control quirks keep it from being universally easy.

Crevice pickup is praised when using the crevice tool for narrow gaps and hard-to-reach areas.

Crevice and grouted-floor pickup has negative customer evidence, especially on grouted tile where grit required repeated passes.

Large-debris hard-floor intake is a weakness because users report thrown particles and litter blowback.

Large-debris hard-floor intake is mixed, with strong customer pellet pickup but CNET criticism that Cheerios were too tall for the head.

Onboard tool storage is a clear convenience when the tools stay accessible and easy to use.

Onboard tool storage is a weakness because the vacuum cannot hold all attachments and tools can fall or require the bag.

Maintenance is generally easy for filters and dust-bin cleaning, but brush-roll hair maintenance can be frustrating for pet owners.

Cord management earns praise for simple wrapping and top cord routing, with some wishing for retractability.

Cord management is a downside because the cord is manual, non-retractable, and can get in the way.

Storage is mostly good thanks to compact footprint, though stability concerns appear in owner feedback.

Upright stability is a weakness in customer feedback, especially when the pod or wand is used and the unit tips easily.

Maneuverability is generally good thanks to swivel steering, but the top-heavy pod and strong pull make handling mixed for some users.

The forward-propel feel helps some users, but others still miss true self-propelled drive.

The self-propelled feel helps carpet cleaning for many users, though the pull can feel too strong in tight spaces.

The accessory package is valued for crevice, upholstery, pet, dusting, and hard-floor tools, though some customers wished more tools were included or stored onboard.

Heavy-duty suitability is favorable, with professional and customer reviewers describing it as appropriate for pets, kids, carpets, and cleaning-house use.

The headlight is consistently useful in positive feedback, though one reviewer questioned non-LED longevity.

Headlights are strongly praised for showing debris on floors, dark corners, and attachment work.

Under-furniture pickup is favorable when the machine or tools reach beneath furniture well.

Under-furniture pickup is a major advantage because Powered Lift-Away lets the head or wand reach under beds and furniture.

Emptying and mess control are strong because the bag avoids the dirty, dusty bin-cleaning process users dislike.

Emptying is usually praised as easy and mess-controlled, though bin capacity and packed pet hair create some complaints.

Hard-floor debris blowback appears in negative Amazon feedback when litter was thrown back at the user.

Airflow blowback is positively addressed in customer evidence where the Shark avoids spitting debris back at the user.

Ownership costs are a concern because OEM bags, belts, and optional pet tools add expense.

Edge and baseboard cleaning gets positive mentions from both the attachment layout and edge-cleaning system.

The finish and styling draw light but positive comments, with reviewers liking the color or clean design.

Design impressions are mostly positive, with reviewers noting modern styling, appealing color, and a premium-looking finish.

Low-profile reach is favorable when reviewers say it gets under furniture better.

Packaging has limited but positive customer evidence, with one buyer saying it was packed well and worked as described.

Surface safety is generally positive where addressed, especially brush-roll shutoff and soft hard-floor use, though some hard-floor concerns remain.

Surface safety is a serious caveat because the active brush can damage rugs or beat one spot while using the hose.

Wool-rug evidence is limited but positive, with one owner saying wool rugs looked better after use.

The Lift-Away/convertible design is one of the product’s core strengths, making it easier to use as an upright, pod, canister-like, or handheld-style cleaner.
