Accessories and Tools
Product 1: Shark HydroVac Cordless Vacuum
4.0

Packages typically include the charging dock/base and Shark's cleaning concentrate; some kits add spare brushrolls and filters, but several reviewers note the overall extras are fairly minimal for the price.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.5

Several reviews highlight a well-rounded in-box kit, commonly including a spare roller, spare filter, cleaning brush, and a bottle of Narwal cleaning solution. This reduces immediate add-on purchases and helps with early maintenance.

Aesthetic design and finish
Product 1: Shark HydroVac Cordless Vacuum
4.4

Reviewers describe a modern look (often with rose-gold accents), and the newer MessMaster styling is called sleeker and more premium/Dyson-like than earlier HydroVac designs.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.8

Multiple reviewers call the S20 Pro sleek and premium-looking, with a clean gray finish and a modern base station. Fit-and-finish impressions are consistently positive in the video and article reviews.

AI, Smart, App and Automation
Product 1: Shark HydroVac Cordless Vacuum
2.5

Smart functionality is mostly limited to automation basics like automatic solution dispensing, self-cleaning, and (on some variants) a stain/solution boost mode. There's no app control or advanced sensor-driven adjustments highlighted in reviews.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.4

Smart dirt sensing and automatic adjustment are repeatedly mentioned, including blue-light style DirtSense indicators and posture detection features. A missing app connection is noted by at least one reviewer, but many still feel the on-device automation and modes cover most needs.

Area Rug Handling
Product 1: Shark HydroVac Cordless Vacuum
2.9

Rug/refresh modes are best treated as a light surface refresh for short-pile rugs. Multiple reviewers found it leaves rugs damp and doesn't lift embedded debris well, so it won't replace a proper vacuum on carpets.

Product 2: Narwal S20 Pro Cordless Vacuum...
No score yet
Assembly and Setup
Product 1: Shark HydroVac Cordless Vacuum
4.5

Assembly is generally simple—insert/click the handle into the body, dock to charge, then fill the clean tank with water + solution. The main setup annoyance mentioned is filling the tank because it may not sit flat on a counter while you pour.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.6

Setup is consistently described as quick, typically involving attaching the handle, charging, and filling the clean tank and solution reservoir. Several reviewers note it feels close to pre-assembled out of the box.

Automatic standby switch
Product 1: Shark HydroVac Cordless Vacuum
No score yet
Product 2: Narwal S20 Pro Cordless Vacuum...
4.6

Auto pause or standby when the unit is stood upright is appreciated for quick interruptions without dripping or running unnecessarily. This feature is treated as a practical convenience during room-to-room cleaning.

Battery and Charging
Product 1: Shark HydroVac Cordless Vacuum
3.4

Charging is commonly described as dock-based and roughly ~4 hours for a full recharge, which is fine for routine sessions but limiting if you want to clean multiple large areas back-to-back.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.2

Battery life is described as competitive for a wet-dry machine, but recharge time is called out as long by some reviewers, with one citing about a 3-hour full recharge. Buyers with very large areas may need to plan around recharge and tank refills.

Bin and Bag
Product 1: Shark HydroVac Cordless Vacuum
3.4

Bagless design uses a combined dirty-water tank with a debris separator/compartment. Separation helps, but solids can still mix with dirty water and require hands-on cleaning.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.5

Reviews praise the dirty tank design for separating solids from liquids and keeping disposal relatively tidy, helped by tight seals and a removable debris basket. Wet debris can still take some manual brushing or scraping to fully remove.

Build quality and durability
Product 1: Shark HydroVac Cordless Vacuum
4.2

Build quality is generally described as solid and well made for the category, aligning with expectations for Shark/Ninja products.

Product 2: Narwal S20 Pro Cordless Vacuum...
3.9

Most impressions point to solid construction and good sealing around the tanks and head, supporting a premium feel. One hands-on reviewer experienced dripping and questioned long-term reliability, suggesting quality control could vary.

Clogging and debris prevention
Product 1: Shark HydroVac Cordless Vacuum
2.3

Clogging can happen with bulky dry items (like Cheerios) and with wet pet-hair clumps catching behind the roller/cover, so occasional manual clearing is sometimes needed.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.4

Design elements like a lower-positioned water system, one-way flow, and dual-direction brush action are credited with reducing clogs and keeping debris moving into the tank. Reviews also connect this to better handling of hair and chunky food bits without the head jamming.

Comparative performance
Product 1: Shark HydroVac Cordless Vacuum
3.9

In comparisons it can beat rivals on ease-of-use and some wet pickup tests, but other models may offer stronger raw suction, better edge reach, better carpet capability, or less messy maintenance.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.6

In head-to-head and multi-model comparisons, the S20 Pro is often ranked at or near the top for overall package, especially on hard floors and for its drying system. Competitors may beat it on reverse pickup, rugs, or certain niche features, but the Narwal is frequently framed as the most complete option.

Controls and UI
Product 1: Shark HydroVac Cordless Vacuum
3.7

Controls are intentionally basic (typically two buttons for power and hard-floor vs rug/refresh modes) with a simple display/indicator for battery and tank alerts. Some users prefer competitors' more detailed readouts (like battery %), and one review mentioned accidentally hitting the mode button.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.5

The on-handle LCD and voice prompts are widely praised for clarity, showing mode, battery, alerts, and sometimes detergent status or timers. Some note the screen is small, but still informative and easy to follow during cleaning and self-clean cycles.

Cord length
Product 1: Shark HydroVac Cordless Vacuum
4.0

In corded head-to-head comparisons, cord length is described as comparable to peers; on cordless variants, cord management isn't part of day-to-day cleaning.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.0

Only one review gives a specific number, citing a 6-foot power cord for the dock, which influences where the base can sit. It is described as usable but not especially long.

Cordless convenience
Product 1: Shark HydroVac Cordless Vacuum
4.7

Cordless grab-and-go convenience is a highlight versus corded floor washers, but it also means working within limited runtime and recharge cycles.

Product 2: Narwal S20 Pro Cordless Vacuum...
No score yet
Cord management
Product 1: Shark HydroVac Cordless Vacuum
No score yet
Product 2: Narwal S20 Pro Cordless Vacuum...
4.4

Where mentioned, reviewers appreciate dock-side cord routing or a cord holder that keeps the charging base tidy. This helps reduce clutter around the storage station.

Dried-On Stain Removal
Product 1: Shark HydroVac Cordless Vacuum
4.0

Dried-on stain removal is often above average (sometimes clearing in just a few passes), but it's inconsistent: one reviewer reported extremely stubborn dried ketchup taking many passes, likely because there's no heat/steam assist.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.3

Dried coffee and similar stains are often removed with a pass or two, and reviewers credit scrubbing pressure and a boost mode for tougher spots. Very sticky or thick dried sauces like ketchup may require multiple passes, and some note the dehydrating dry-down can leave color residue that needs manual roller cleaning.

Ease of use
Product 1: Shark HydroVac Cordless Vacuum
4.4

Ease of use is repeatedly highlighted: light weight, simple controls, and straightforward docked self-cleaning make it approachable for routine hard-floor cleaning. Usability complaints mainly center on messy emptying and limitations in corners/under furniture.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.6

Ease of use is a recurring positive: light weight, clear on-screen prompts, and one-button self-cleaning make daily cleanup straightforward. A few critiques relate to learning how to avoid backward passes and keeping up with tank emptying for best results.

Edge and Baseboard Cleaning (Hard Floors)
Product 1: Shark HydroVac Cordless Vacuum
2.8

Edge and baseboard reach is a recurring weak spot. Some competitors clean closer to walls, and reviewers mention corner/edge limitations or measurable gaps at the sides.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.7

Edge performance is repeatedly called exceptional, with reviewers describing near-zero gaps along baseboards and strong cleaning at the front edge as well. This is one of the most consistently praised differentiators versus competing wet-dry models.

Emptying and Mess Control
Product 1: Shark HydroVac Cordless Vacuum
3.2

Liquid empties easily, but solid debris often has to be pushed or pulled out by hand, and some users report drips while carrying the tank. It's improved versus a mop bucket, but not mess-free.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.5

Reviewers like the way the dirty tank separates solids, which helps keep emptying neater and reduces splashy cleanup. However, wet debris can adhere inside the tank and may need periodic scrubbing for a truly clean reset.

Filtration / Dust Containment
Product 1: Shark HydroVac Cordless Vacuum
No score yet
Product 2: Narwal S20 Pro Cordless Vacuum...
3.9

Filtration is generally handled by a washable filter in or near the dirty-water tank; reviewers note it needs rinsing and fully drying before reuse. Some packages include a spare filter, which helps reduce downtime.

Floor Drying Time
Product 1: Shark HydroVac Cordless Vacuum
4.6

Hard floors typically dry within minutes. The HydroVac often leaves a visible moisture trail while cleaning, which helps you track coverage but doesn't usually linger.

Product 2: Narwal S20 Pro Cordless Vacuum...
3.8

Floors are often left reasonably dry after a pass, especially compared with older wet mops, and the heated roller drying helps after-use drying. One reviewer still observed dripping and wet roller marks when the unit was set down, so drying outcomes can depend on handling and mess type.

Floorhead design
Product 1: Shark HydroVac Cordless Vacuum
3.4

The floorhead is often described as bulky and not great in corners; multiple reviewers also note it won't fit under low furniture. A low front clearance can also limit pickup of bulky cereal-like debris (and can contribute to clogging behind the roller).

Product 2: Narwal S20 Pro Cordless Vacuum...
No score yet
Floorhead Seal on Hard Floors
Product 1: Shark HydroVac Cordless Vacuum
4.6

The soft roller design is credited with maintaining good contact on hard floors, helping it handle fine dust without losing performance when moving over slightly larger debris.

Product 2: Narwal S20 Pro Cordless Vacuum...
No score yet
Fresh Liquid Pickup Speed
Product 1: Shark HydroVac Cordless Vacuum
4.2

Fresh liquid pickup is generally efficient, with at least one test describing it as best-in-class among cordless units for handling lots of liquid in fewer passes. A separate comparison suggests a rival can outperform it when overloading with large volumes of wet material.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.4

Fresh spills and wet messes are commonly cleaned in a single forward pass, including coffee, soda, cereal milk, and yogurt-like messes. Reverse-pass pickup is reported as weaker in at least one test, so best results come from forward cleaning.

Hair Pickup — Hard Floors
Product 1: Shark HydroVac Cordless Vacuum
3.5

On hard floors, it can pick up pet hair while mopping, but hair may form wet clumps in the tank and can sometimes snag near the roller cover—so results vary by hair volume and moisture.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.5

Hair pickup on hard floors is consistently positive in demonstrations, and reviewers say hair is carried into the tank rather than staying on the roller. Results are especially strong when paired with the anti-tangle roller design.

Hair‑Wrap / Tangle Resistance
Product 1: Shark HydroVac Cordless Vacuum
No score yet
Product 2: Narwal S20 Pro Cordless Vacuum...
4.8

Anti-tangle performance is a consistent highlight, with multiple long-hair tests reporting zero wrap thanks to dual comb and dual rotation design choices. This is repeatedly positioned as a major improvement over wet-dry competitors that require cutting hair off the roller.

Hard Floor — Fine Dust Pickup
Product 1: Shark HydroVac Cordless Vacuum
4.6

Fine debris pickup on hard floors is consistently strong (examples include sugar, coffee grounds, dust and other small particles), aided by the soft roller and good floor contact.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.2

Reviews show strong pickup of fine particles like dust and flour on hard floors in forward passes. Performance can drop when cleaning backward, where some fine debris may be left behind.

Hard Floor — Large Debris Intake
Product 1: Shark HydroVac Cordless Vacuum
3.9

Large-debris performance is mixed: it can handle things like rice, litter, and sticky oatmeal-style messes, but multiple reviews mention cereal/Cheerios-type pieces being pushed, broken up, or clogging behind the roller.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.3

Large debris like cereal, rice, chips, and pet food is generally handled well, often with minimal scatter when moving forward. Backward passes can be less reliable, with some debris getting pushed or caught behind the wheels.

Headlight and LED lights
Product 1: Shark HydroVac Cordless Vacuum
4.0

Headlights get mixed feedback: some reviewers find them bright and genuinely helpful for spotting dirt, while others say they're too dim or narrowly aimed to be very useful.

Product 2: Narwal S20 Pro Cordless Vacuum...
2.0

A frequent complaint is the lack of built-in headlights, which can make it harder to spot debris in dim rooms or under furniture. Reviewers generally treat this as a convenience miss rather than a deal-breaker.

Innovation compared to competitors
Product 1: Shark HydroVac Cordless Vacuum
3.1

Compared with higher-end competitors, it's considered a capable but more basic design—lacking features like variable water/suction, better edge cleaning, heated/steam assist, hot-air roller drying, or smart guidance.

Product 2: Narwal S20 Pro Cordless Vacuum...
No score yet
Low-profile design
Product 1: Shark HydroVac Cordless Vacuum
2.7

It isn't particularly low-profile; several reviews mention the body design prevents it from getting under low tables or furniture.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.8

The low profile when laid flat helps it reach under toe-kicks and furniture, and reviewers repeatedly point to this as a practical advantage. It pairs well with posture detection that helps prevent water leaks when the unit is lowered.

Maintenance requirements
Product 1: Shark HydroVac Cordless Vacuum
3.5

Maintenance is the main ongoing downside: you'll still need to empty the dirty tank frequently, rinse out compartments/filters, and ideally air-dry the brushroll and filter to avoid odor or mold.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.0

Maintenance is generally reduced by the automated wash and heated dry, but users still need to empty the dirty tank and rinse and dry filters regularly. Neglecting post-clean tank care can cause odors, and some wish the self-clean used more water for an even cleaner reset.

Maneuverability and Handling
Product 1: Shark HydroVac Cordless Vacuum
4.2

Handling is broadly praised: smooth swivel steering and forward traction make it easy to guide around obstacles. The biggest handling limitations come from the head/body bulk, which can make tight angles and low-clearance furniture more difficult.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.7

Handling is a standout theme: reviewers consistently call the unit light, easy to steer, and comfortable thanks to a pivoting head and low center of gravity. Lay-flat movement and swivel action make it feel less fatiguing than many wet-dry rivals.

Mopping performance
Product 1: Shark HydroVac Cordless Vacuum
4.4

Across reviews, hard-floor cleaning is the strong suit: it effectively vacuums + mops in one pass, removes everyday grime, and handles many spills well. Performance can vary on the stickiest, most dried-on messes where repeated passes may be required.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.3

Most reviews show strong one-pass vacuum-and-mop results on typical spills and tracked-in dirt, with multiple modes to tailor water and suction. Heavy muddy sludge or cleaning while pulling backward can expose weaknesses, including streaking or debris left behind in a few accounts.

Noise level
Product 1: Shark HydroVac Cordless Vacuum
3.3

Noise is typically in the high-70 dB range in testing, and several reviews call it louder than average. The self-clean cycle is often the loudest part.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.7

Cleaning and especially the drying cycle are often described as unusually quiet for the category, with some reviewers measuring roughly 39 to 43 dB during roller drying. Quiet mode cleaning is also noted as comfortable for home use.

Odor control
Product 1: Shark HydroVac Cordless Vacuum
3.9

Odor control is generally good thanks to an antimicrobial/odor-neutralizing roller and the self-clean cycle, with some reviewers noting no lingering smells. However, multiple sources warn that leaving the roller wet (or skipping proper drying) can lead to mildew/odor.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.4

Heated drying and a fully dried roller are credited with minimizing musty odors between uses. At the same time, reviewers warn that leaving dirty water or neglecting tank cleaning can still create lingering smells.

Ongoing ownership costs (bags, filters, batteries)
Product 1: Shark HydroVac Cordless Vacuum
3.0

Consumables include cleaning solution plus periodic brushroll/filter replacements; costs are manageable but ongoing. At least one review warns that using non-approved fluids may affect warranty coverage.

Product 2: Narwal S20 Pro Cordless Vacuum...
No score yet
Overall opinion
Product 1: Shark HydroVac Cordless Vacuum
4.2

Overall sentiment is positive for mostly hard-floor homes looking to save time with a vac-mop. The most repeated caveats are mediocre rug/carpet results and the hands-on, sometimes gross emptying/cleaning routine.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.5

Across the set of reviews, overall sentiment is strongly positive, with several reviewers ranking it as a top pick for hard floors. The most negative feedback comes from one reviewer who saw streaking and dripping during a heavy muddy test and withheld a recommendation, plus recurring complaints about reverse pickup and missing headlights.

Pet-Ready Features
Product 1: Shark HydroVac Cordless Vacuum
4.0

It's frequently used in pet homes for muddy paw prints, accidents, and hair. The tradeoff is that pet hair tends to make the dirty-tank emptying experience messier and more unpleasant.

Product 2: Narwal S20 Pro Cordless Vacuum...
No score yet
Price and Value
Product 1: Shark HydroVac Cordless Vacuum
4.1

Value is generally seen as strong versus premium vac-mops, especially when priced around the mid-$200 range, but it can feel expensive compared to basic spray/steam mops. Many reviewers frame it as worth it mainly for hard-floor, one-pass convenience.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.1

Value is usually framed as strong given the feature set and performance on hard floors, especially when discounted from the roughly 499 USD list price. Value perception drops if reverse cleaning, missing headlights, smaller tanks, or longer recharge time are major pain points.

Runtime
Product 1: Shark HydroVac Cordless Vacuum
3.6

Reported runtime varies: many reviewers cite ~15–23 minutes, while at least one measured test reported ~29 minutes. In practice it's usually enough for kitchens/entryways and several rooms, but not ideal for whole-home, uninterrupted cleaning.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.4

Runtime in everyday or smart-style modes is described as strong, with one measured test around 39 minutes in smart mode and multiple claims of up to about 60 minutes in quieter settings. Actual coverage depends heavily on mode choice and how dirty the floors are.

Sanitizing performance
Product 1: Shark HydroVac Cordless Vacuum
No score yet
Product 2: Narwal S20 Pro Cordless Vacuum...
4.6

High-temperature self-cleaning and heated drying are repeatedly positioned as a hygiene advantage that reduces bacterial growth and keeps the roller fresher. Reviewers treat it as more sanitary than air-drying rollers that stay damp.

Self-cleaning cycle
Product 1: Shark HydroVac Cordless Vacuum
4.2

Dock-based self-cleaning is a standout convenience and often leaves the brushroll/system much cleaner after ~1–2 minutes. It can be loud, and it doesn't fully eliminate manual cleaning or the need to dry parts between uses.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.6

The self-clean and heated self-dry base is one of the biggest strengths, with multiple reviewers saying the roller comes out genuinely dry. Drying time is often described as sensor-controlled (roughly 30 to 80 minutes), though a few reviewers wish the wash used more water or note that strongly colored sauces may require extra manual cleaning.

Self-propel feature
Product 1: Shark HydroVac Cordless Vacuum
4.2

Several reviews mention a noticeable forward pull/traction from the spinning roller that reduces pushing effort. It helps with glide, but it's not the same as a fully powered wheel-drive assist.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.4

Several reviewers describe helpful push-pull assistance that makes the unit feel self-propelled, especially in smart modes. One review notes there are no dedicated self-propulsion wheels, suggesting the assistance may come from roller traction and can feel different than true powered drive.

Software-update support / feature longevity
Product 1: Shark HydroVac Cordless Vacuum
1.0

Reviewers specifically note there's no app or firmware-update ecosystem, so feature longevity is mostly hardware-based rather than improved via updates.

Product 2: Narwal S20 Pro Cordless Vacuum...
No score yet
Solution / Liquid system
Product 1: Shark HydroVac Cordless Vacuum
4.1

Most variants automatically dispense water/solution as you clean (no trigger), and some newer versions add a boost mode for extra solution on stains. This is convenient, but it offers less manual control than trigger-based competitors and often works best when paired with the recommended cleaning concentrate.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.6

The separate detergent reservoir and auto-dosing system are frequently praised, often described as lasting up to about 40 days and allowing solution on or off control. Reviewers also like having a suction-only mode for liquid pickup without spraying detergent.

Steam Cleaning
Product 1: Shark HydroVac Cordless Vacuum
1.0

Reviews note there's no steam/heated cleaning option, which can make it slower on the toughest dried-on stains compared with steam-capable alternatives.

Product 2: Narwal S20 Pro Cordless Vacuum...
No score yet
Storage footprint and upright-stand stability
Product 1: Shark HydroVac Cordless Vacuum
3.1

Storage requires the dock/base and full-height space (it doesn't fold away). Some users report small drips/puddles if the unit is left standing upright, while the base can catch residual drips when docked.

Product 2: Narwal S20 Pro Cordless Vacuum...
3.8

The dock base needs an outlet nearby, so placement can be less flexible in some rooms, and a few reviewers mention keeping it close to a plug. Most still find the storage setup straightforward once a spot is chosen.

Streaking / Residue
Product 1: Shark HydroVac Cordless Vacuum
4.2

Most reviewers report clean results without obvious streaks, and several explicitly say floors aren't left with streaking. A minority report potential dirty streaks on white tiles or when the extraction/water-delivery system is pushed hard.

Product 2: Narwal S20 Pro Cordless Vacuum...
2.8

Most demos show clean-looking passes, but one reviewer reported visible streaks and a failed white-glove test after cleaning a heavy muddy mess. This suggests residue can occur in extreme grime or if the machine is set down while the roller is still wet.

Suction and Airflow
Product 1: Shark HydroVac Cordless Vacuum
3.3

Suction is generally described as average for a vac-mop and below a dedicated vacuum—especially for dry vacuuming tasks and carpet-like surfaces.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.5

Most reviewers describe strong hard-floor pickup and cite about 20,000 Pa suction, with convincing performance on mixed dry and wet messes. A recurring caveat is that pickup is weaker when pulling the unit backward, where debris can get caught near the wheels.

Support and Reliability
Product 1: Shark HydroVac Cordless Vacuum
No score yet
Product 2: Narwal S20 Pro Cordless Vacuum...
3.0

Support and reliability feedback is mixed: one review flags stock availability and a short warranty, while another reports dripping or leaking after a heavy muddy cleanup. Most other reviews do not report failures, but these flags add some risk for cautious buyers.

Under-Furniture Pickup
Product 1: Shark HydroVac Cordless Vacuum
2.7

Under-furniture reach is limited because the body/head doesn't recline fully and the head is bulky, so low-clearance spaces are harder to clean.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.8

The ability to recline fully and clean under beds, couches, and cabinets is frequently praised, aided by a low profile in the laid-flat posture. Some reviews also mention automatic power changes when going flat to maintain pickup.

Water tank
Product 1: Shark HydroVac Cordless Vacuum
3.2

Clean and dirty tanks are frequently called small (commonly around ~0.5 L clean and ~0.36–0.38 L dirty). Some users finish a typical session on one fill, but larger homes may require refilling and multiple dirty-tank dumps.

Product 2: Narwal S20 Pro Cordless Vacuum...
3.8

Tank sizes are described as adequate for routine cleaning, with published or reviewer-cited capacities around 0.79 L clean and 0.67 L dirty. Some reviewers feel the clean tank is on the smaller side and one test required emptying the dirty tank after about 20 minutes, so large homes may need mid-clean stops.

Weight
Product 1: Shark HydroVac Cordless Vacuum
4.3

Weight is typically around ~8–8.5 lb / ~4 kg—light for a wet/dry floor washer, though a bit bottom-heavy in hand.

Product 2: Narwal S20 Pro Cordless Vacuum...
4.7

Many reviews call out the low weight, commonly around 9 to 9.5 pounds, making it easier to carry upstairs and less tiring to push. Weight is often cited as one reason it feels more agile than rivals.
