Compare Shark Stratos Upright Vacuum vs Simplicity Vacuums Allergy Upright Vacuum, S20EZM

Ease of use was strong overall, with reviewers praising usability and all-around performance.

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

Large-debris hard-floor pickup was strong, with little scattering and successful pickup of rice, oatmeal, crumbs, and mixed debris.

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

One comparison praised the head's ability to form a tight seal for deep cleaning.

Hard-floor sealing is weak where reviewers report no squeegee effect and debris being thrown back.

Hair-wrap resistance was strongly praised by most reviewers, though one lab test found long hair tangling around the brush roller.

Hair-wrap/tangle resistance is a concern in pet homes when long hair is linked to brushroll lockup.

One test noted an initial odd debris transfer result but found the vacuum did not appear to clog in later trials.

Clogging prevention is a weakness in Amazon feedback, with users reporting easy clogs and teardown hassle.

Hard-floor fine-dust performance was consistently strong, with reviewers praising dust pickup on bare floors and hardwood.

Fine dust hard-floor evidence is mixed, with some strong cleaning praise and other hard-floor complaints.

LED lighting evidence was limited and mildly negative, with one comparison saying the Stratos lights were less pronounced than another Shark.

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

Maintenance was mixed: washable filters were a plus, but odor cartridges and hair cleanup could add extra work.

Maintenance is mixed-to-negative because belts, filters, and brushroll cleaning can require ongoing attention.

Stability was a clear weakness in one hands-on review, where the vacuum tipped easily during stretched-hose cleaning.

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

High-pile performance was mixed: some reviewers praised thick-carpet cleaning, while others found sugar, rice, or sand left in shaggy fibers.

High-pile and thick carpet performance is generally strong, helped by brush agitation and height adjustment.

Low-pile carpet performance was excellent, including a 97% pickup result and strong real-world rug cleaning impressions.

Low-pile carpet evidence is positive but less detailed, mainly tied to nap revival and general carpet cleaning.

Versatility was a major selling point, with the lift-off canister making it feel like two vacuums in one.

Versatility is good for carpets, tools, and above-floor cleaning, but hard-floor limitations reduce flexibility.

The hose and wand reach were praised for giving more than 8 feet of extended reach.

Hose reach is mixed: videos praise long reach, while some owners find the attached hose too short or awkward.

Above-floor and upholstery cleaning were strong, especially with the removable canister and HairPro-style powered tool.

Above-floor pickup is mixed: hose suction can be strong, but upholstery and long cat hair disappoint some owners.

One lab review found hair could catch in tines and near the soft roller, creating a de-tangling concern.

Hair-channel and brushroll serviceability is a concern where users cannot easily clean a locked beater bar.

Pet-focused evidence was generally positive, especially for pet hair pickup and sealed filtration, though pet-hair results varied by surface in broader testing.

Pet-ready performance is a major strength for carpet hair and allergens, though long-haired pets can expose brushroll issues.

Tool changes were generally easy, with reviewers praising the removable wand and straightforward access for brushroll cleaning.

Tool changes are usually easy with the included setup, though compatibility with older attachments is limited.

The dust bin was usually liked for size and easy removal, though dog hair could fill it quickly in real home use.

The bagged system is a strength because users like simple bag changes, contained dust, and steady suction.

Area-rug handling was a weakness versus newer PowerDetect-style designs and required more passes on shaggy rugs.

Area-rug handling is polarized: some rugs revived, while one flat-weave rug was damaged by the roller.

Cord length was viewed positively, with reviewers calling the 30-foot range sufficient and convenient.

Cord length is mixed across homes: some call it long, while others say larger spaces still require replugging.

Crevice and groove pickup was a standout strength, with tests praising its ability to lift sand and debris from cracks.

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

Handling was split: reviewers liked the swivel and obstacle navigation, but some found the bulky canister harder to maneuver.

Handling is mixed: it rolls or maneuvers well for some, but weight and suction make pushing difficult for others.

Filtration was a major strength, with reviewers praising the sealed HEPA setup and very low particle release in testing.

Filtration and dust containment are among the strongest themes, especially for allergies and bagged dust control.

Under-furniture cleaning was a standout benefit because Powered Lift-Away made low-profile furniture and hard-to-reach areas easier.

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

The Stratos was treated as an advanced flagship that combines Shark's prior best upright features with newer suction and odor technology.

Innovation centers on the five-level height system, described as unusual for uprights in this class.

Emptying was generally clean and easy, with top and bottom dust-cup access reducing the need to touch debris.

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

Carpet hair pickup was often praised, but one lab review found only average low-pile performance and weaker high-pile results.

Carpet hair pickup is usually praised, especially for dogs, cats, and high-shedding homes.

Medium-pile and general carpet pickup was strong, including high sand collection and praise for DuoClean carpet performance.

Medium/all-pile carpet evidence is favorable, with reviewers calling the carpet performance outstanding or broadly ideal.

Weight was the main ergonomic drawback, with reviewers calling it bulky, heavy, or cumbersome to carry.

Weight is one of the clearest tradeoffs, with users calling it substantial or hard to push despite cleaning power.

Small-space suitability was supported by precise swivel motion and easy navigation around tight spaces and obstacles.

Small-space suitability is strong because several users cite compact footprint and easy closet storage.

Overall sentiment was strongly positive, with multiple reviewers calling it one of the best uprights or a favorite despite weight and shag-carpet caveats.

Overall opinion is positive but not unanimous: reviewers praise cleaning power while noting convenience and durability tradeoffs.

Included tools were useful, especially HairPro-style pet and upholstery tools, but some reviewers wanted more than the basic crevice and upholstery attachments.

Tools are useful and available, but Amazon reviewers split over whether the included set is adequate.

The brush rollers gave a mild self-propel feel, helping the vacuum move forward during use.

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

Reviewers saw it as capable of serious cleaning, with enough power and hardware quality for heavier-duty use cases.

Heavy-duty suitability is good for frequent pet-home use when the unit stays intact, with workhorse praise from some owners.

Airflow blowback was well controlled in one home test, where rice and litter did not shoot across the floor.

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

Ownership costs were seen as reasonable because filters last a long time and are not expensive to maintain.

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

Stair usability was mixed but mostly workable: Lift-Away helped, while the full unit's weight made carrying it upstairs less ideal.

Stair use is limited by weight and lift-handle complaints despite useful step/edge attachments.

Noise was a recurring tradeoff: one test found it only slightly louder than a cheaper Shark, while another called it clearly noisy.

Noise is a recurring concern, though a few users find the tone tolerable or quieter than prior vacuums.

Edge and wall cleaning were strong across tests, with reviewers noting good pickup along wall edges and coffee/rice edge tests.

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

Comparative testing placed the Stratos near or ahead of key rivals overall, though some competitors beat it in specific carpet or suction tests.

Comparative comments often favor the Simplicity over Shark-type vacuums, though Rainbow-style deep cleaning can outperform it.

Reviewers consistently described the Stratos as extremely powerful, with strong suction and airflow that helped it excel in deep debris pickup.

Suction is the strongest recurring praise, with multiple reviewers calling it powerful or excellent.

Controls were praised as accessible and well-labeled, with handle-based floor settings making adjustments simple.

Controls are mixed: the height dial is easy, but many users dislike the always-on roller and limited suction control.

Build quality was praised, with reviewers calling out hefty plastic connections and sturdy hardware.

Build quality is disputed: video reviewers praise durable parts, while Amazon complaints cite cheap plastic and failures.

Low-profile cleaning was a strength because Powered Lift-Away helped reach under furniture where uprights often struggle.

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

The dual-brush floorhead was usually praised as efficient and useful, though one reviewer wished it performed better on certain carpets.

The floorhead has strong agitation but mixed design feedback because the brush roll cannot be shut off.

Setup was easy overall; one comparison called assembly more involved, but hands-on reviews found it simple and intuitive.

Assembly is treated as very easy, with reviewers emphasizing the simple handle and hose setup.

Value was viewed positively because reviewers saw premium cleaning, filtration, and versatility at a lower price than some rivals.

Value is generally favorable, especially against higher-end vacuums, but ongoing parts costs temper the score.

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

Powered Lift-Away was one of the strongest points, repeatedly praised for making the upright act like a more flexible canister-style vacuum.

Longevity feedback is mixed, ranging from multi-year praise to early belt, hose, motor, and handle failures.

One reviewer praised the brush rolls stopping when upright as a useful safety behavior.

The bag-full indicator receives both praise for usefulness and complaints when it fails to reset.

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

Hard-floor hair pickup was supported by one review's combined bare-floor hair test, but evidence was limited.

Odor control was mixed: one review liked the idea or masking effect, but multiple hands-on reviewers barely noticed it or saw it as added maintenance.

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

Packaging quality was praised in one hands-on review for organized wrapping and easy unboxing.

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.

Reverse-pass carpet performance was good but not perfect, with one test noting the Stratos missed more sand than Dyson on the return pass.

Support and reliability are mixed: warranty backing and refunds help, but some service attempts disappoint.
