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.
Reviewers consistently praise the slim, streamlined look, describing the handle as ultra-thin, attractive, and purposefully minimal.
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.
Smart features are limited: one review says the machine can be scanned into MyDyson for help content, while another praises Dyson for not burying core operation in an app.
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.
The setup is repeatedly described as a two-part system, with the handle and cleaning head assembled or stored separately rather than as one always-ready unit.
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.
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 coverage is generally solid for this format, with repeated mention of around 30 minutes per charge plus a removable or swappable battery design.
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.
One review highlights the floor head’s separate dirty-water handling and a solids tray on top, which helps keep larger debris out of the liquid tank.
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.
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.
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.
Compared with mops, larger Dyson washers, and stronger rivals, PencilWash usually gives up raw cleaning power in exchange for compact size and easier handling.
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 are described as simple and minimal, usually centered on a few buttons, though review coverage is mixed on how much charge or mode information is shown on the machine.
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.
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.
One review explicitly calls out the cordless design, framing it as a grab-and-go hard-floor cleaner with no cord management burden.
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.
The strongest hands-on stain testing says PencilWash can remove dried-on messes, but tougher residue takes repeated passes and more time than stronger competitors.
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.
Everyday operation is consistently described as simple and approachable, especially during active cleaning, even though cleanup afterward is far less convenient.
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 cleaning is a weakness in the main hands-on test, which says the roller does not reach fully to the sides of the floor head.
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 is one of the biggest pain points, with repeated warnings about unsealed or spill-prone dirty-water handling even though one review found the carry tray somewhat helpful.
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.
Reviews describe a filter-free, waste-separation design that aims to avoid trapped sludge and keep dirt routed into separate tanks or compartments rather than a traditional filter.
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.
Drying feedback is mixed: some reviewers say floors can feel damp right after use, while another says remaining moisture evaporates quickly.
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.
The floor head gets credit for packing clean and dirty tanks into a compact integrated design, though that smaller head also comes with performance compromises.
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 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.
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.
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.
Reviews say PencilWash can handle loose particles, wet messes, and everyday hard-floor debris, but not with the same power or confidence as stronger wet-dry machines.
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.
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.
Its standout innovation is the unusually shrunk-down wet-cleaner format, which one review says has little direct competition at this size.
The low-profile design is repeatedly tied to its near-flat cleaning angle, helping the machine stay slim enough for low furniture and tight clearance.
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 demands are high in the hands-on reviews, which describe frequent manual washing, drying, and careful handling after each session.
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 is the clearest strength across reviews, with repeated praise for easy steering, tight turning, and nimble handling around furniture and cramped areas.
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 is described as good enough for routine spills and everyday hard-floor messes, but several reviews say it falls short of deeper-cleaning rivals.
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.
One hands-on review says PencilWash is very quiet in operation, with little more than a gentle whir while cleaning.
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 feedback is mixed: some reviews think the filter-free separation design should reduce trapped smells, while others worry manual drying could still lead to mould or odor issues.
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.
Overall sentiment is mixed but not flatly negative: some reviewers really like the convenience and form factor, while others say the cleaning and upkeep issues make it hard to recommend.
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.
Value comes down to priorities: several reviews call it cheaper than many Dyson or competitor options, while others still see the price as steep given the cleaning and maintenance compromises.
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 lands around 30 minutes in the reviews, which is usually framed as enough for smaller homes but short for bigger areas or heavier cleaning.
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.
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.
The lack of self-cleaning is a major recurring complaint: reviews repeatedly note there is no self-clean mode or drying dock to automate post-use cleanup.
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.
Two reviews say the machine helps pull itself along, giving it an easy, assisted feel during normal floor washing.
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.
The liquid system is widely praised for feeding fresh water to the roller, offering adjustable hydration, and supporting non-foaming cleaning solution for harder messes.
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.
One reviewer specifically frames the lighter build as easier to carry upstairs for bathroom-floor cleaning than bulkier wet floor cleaners.
Storage is a tradeoff: the handle can dock upright, but several reviews say the two-piece setup and basic cone-style dock make it less tidy or stable than it looks.
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.
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.
Multiple reviews state that PencilWash does not use suction, relying instead on hydration and agitation, so it lacks the stronger pickup force reviewers associate with wet-dry vacuums.
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.
Heavy-duty cleaning is not a strength: reviews repeatedly say it is best for maintenance cleaning and smaller everyday messes, not the toughest stains or biggest jobs.
Small homes and apartments are the clearest fit, with several reviews saying PencilWash makes the most sense where storage is tight and full-size wet cleaners feel bulky.
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 reach is one of the product’s most praised traits, with multiple reviews highlighting how easily it gets under couches, beds, and other low-clearance areas.
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.
Versatility is limited: reviews describe PencilWash as useful for hard-floor wet cleanup and light everyday messes, but not as an all-in-one replacement for a regular vacuum or deeper cleaner.
Reviews consistently describe small built-in clean and dirty water tanks in the floor head, which help the slim design but limit how much area you can cover before refilling or emptying.
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.
Light weight is another major selling point, with repeated references to roughly five pounds or 2.2kg and a much easier feel than bulkier wet cleaners.
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.
