Compare Ultenic Cordless Vacuum Mop All in One Combo, AC1 Elite vs Dyson PencilWash

Tool and roller removal was described as easy, with reviewers saying the roller cover or brush popped out with little effort.

The tool-change experience was criticized because the PencilWash and PencilVac heads do not interchange, leaving users to buy separate machines.

Groove pickup evidence was positive in one review where the grout cleaned up noticeably.

Grooves and grout were a weakness in the video review, which said gap-heavy floors were not a good match.

Reviewers praised suction as efficient and powerful, especially on hard-floor filth and spills, with one external user-summary quote also highlighting impressive suction.

Reviewers treated the lack of suction as a clear limitation for solid messes, deep cleaning, and spotless results, with one reviewer saying the machine lacked power.

Under-furniture pickup was limited because the vacuum could not lie flat enough to reach under a sofa.

Under-furniture pickup was a standout strength because the flat, low-profile body repeatedly reached couches, beds, cabinets, and low-clearance furniture.

Low-profile reach was poor because the vacuum could not be laid completely flat.

The low-profile design received strong praise for sliding under furniture, tight spots, and areas bulkier cleaners cannot reach.

The self-cleaning cycle was broadly praised as time-saving and low-effort, though one reviewer said it did not leave the roller perfectly dry.

The missing self-cleaning cycle was one of the most consistent complaints across reviews, especially compared with larger wet-dry cleaners.

Storage feedback was mixed: reviewers liked upright standing and the base, but one found docking the vacuum a bit of a struggle.

Storage was a repeated weakness because the two-piece design, drip tray, drying needs, and awkward dock made the product less tidy than expected.

Noise was mixed to negative: the cleaning cycle and voice prompts were described as noisy or loud, though one review noted alerts can be turned off.

Noise drew strong praise in the hands-on review that described the PencilWash as very quiet and usable without disturbing others.

Residue and finish were positive in one review that reported a shiny, clean floor after use.

Residue removal was mixed-to-negative because sticky residue required extra time and another reviewer doubted roller-only cleaning could give a spotless finish.

Versatility was strongly praised because the AC1 combines vacuuming, mopping, liquid pickup, and self-cleaning in one machine.

Versatility was limited because reviewers said it does not replace a vacuum, is not a do-everything machine, and lacks interchangeable cleaning heads.

Floor drying was positive in one review, which said floors were clean and dry quickly.

One hands-on review warned that extra moisture mode leaves the floor feeling damp.

Edge and corner cleaning was positive, with reviewers saying it got into corners and cleaned nearly to the right edge.

Edge cleaning was a clear weakness in the hands-on review because the roller could not clean all the way to room edges.

Mopping performance was one of the strongest attributes, with every review giving positive hard-floor cleaning or mopping outcomes.

Mopping performance was mixed: reviewers liked routine maintenance cleaning but criticized deep scrubbing, larger messes, and tougher stains.

Water-tank feedback was positive, with reviewers praising the dual-tank design and large one-liter capacity.

Water tank feedback was context-dependent: acceptable for smaller spaces in one test, but small tanks and refills were concerns elsewhere.

Emptying was mixed: the separator could make the process easier, but another reviewer called the dirty-water tank messy.

Emptying and mess control were major concerns, with reviewers describing disgusting cleanup, spill risk, leaking, and only moderate help from the solids tray.

The dirty-water and solids separation design was praised as unique and easy to use.

Dirty-water handling was mixed: one review praised the solids tray, while another warned the unsealed reservoir could spill.

Comparative performance was positive, with reviewers finding the AC1 better value than a named competitor and at least as effective as a previous wet/dry vacuum.

Comparative performance was mixed-to-negative, with the PencilWash praised for size and reach but often judged behind larger wet-dry cleaners for power, edge work, and self-cleaning.

Overall opinion was strongly positive across all reviews, with reviewers repeatedly calling it transformative, impressive, or a favorite hard-floor cleaner.

Overall opinion was mixed, ranging from excitement and praise for the compact format to strong criticism of performance, price, and cleanup.

Maintenance was easier than many alternatives but not effortless, with reviewers still needing to rinse, dry, and empty parts.

Maintenance was the biggest practical drawback: reviewers repeatedly criticized manual washing, drying, and cleanup after use.

Runtime was consistently praised, with reviewers describing whole-home cleaning, favorable cordless comparisons, and little battery loss.

Runtime was acceptable for small homes and ordinary cleaning but less convincing for larger homes or long sessions.

Setup was mostly described as quick and simple, though one video unboxing found the process confusing and complicated.

Setup/storage of the two-piece cleaner was mildly criticized, with one reviewer saying separating the cleaner could be a bit of a faff.

Stain and tougher soil evidence was mixed: one reviewer saw tile improve dramatically after several passes, while another said it was not as good as a scrubbing mop.

Dried-on stain evidence was weak-to-mixed: one reviewer found pressure stalled the roller, while another removed a tough stain only slowly.

Large debris intake was positive in one review that reported visible dirt and debris were picked up.

Large-debris evidence was mixed: one reviewer said loose particles were collected quickly, while another expected bigger messes to be a struggle.

Controls and display were usually praised as intuitive, clear, and easy to read, though one video reviewer struggled to find the power controls during setup.

Controls were seen as simple and clean, but reviewers also noted limited customization, no full charge display, and some confusion around boost operation.

Floorhead design drew positive comments for its thoughtful construction and soft fuzzy roller.

Floorhead design split reviewers: its compact head helped with gaps and chair legs, but the drip tray and hard-to-access dirty area drew criticism.

Most value judgments were positive, especially for features and hard-floor performance, but one reviewer noted it was pricier than non-wet stick vacuums.

Value opinions were split: several reviews called it competitive or affordable for Dyson, while negative hands-on reviews found it hard to recommend at the price.

Odor control was a weakness when the dirty-water tank was not emptied quickly.

Odor control was mixed: filter-free design was praised as a way to avoid smells, but wet brush drying and mold/odor worries remained.

Battery and charging evidence was positive, with reviewers appreciating ready charging and one reporting a full charge within an hour.

Battery and charging were adequate for quick cleaning, helped by swappable batteries, but the no-display charge feedback and shorter runtime drew caveats.

Weight was mixed: several reviewers found it light enough or easier than prior wet/dry vacuums, while others called it heavy.

Weight was one of the strongest positives, with reviewers repeatedly praising the ultra-light feel and easy handling.

Fresh liquid pickup was consistently praised, with reviewers saying spills were handled quickly and made kitchen cleanup easier.

Fresh or smaller liquid-mess pickup was viewed positively, with reviewers describing red wine or spilt milk-type messes as easy or effective targets.

Handling was mixed: reviewers liked the self-driven movement and easy rolling, but some found the forward pull or weight awkward.

Maneuverability was one of the strongest themes, with reviewers praising its glide, swivel, grip, one-handed handling, and lightweight feel.

Heavy-duty suitability was mixed: one review discouraged very messy spaghetti-style cleanup, while another found thick spills and debris were handled within a couple passes.

Heavy-duty suitability was limited: reviewers said very dirty messes or deeper cleaning needs call for something more powerful.

Design impressions were positive, with reviewers calling the machine futuristic, unique, funky, and visually distinctive.

Reviewers broadly liked the slim, streamlined look and mop-like feel, even when they criticized the cleaner’s performance or storage.

Ownership-cost evidence was negative around the branded cleaning solution, which one reviewer could not find for sale.

Ownership-cost evidence was mixed-to-negative, with concerns about wasteful cleanup supplies and spare batteries adding cost.

The one stairs-focused review was positive, saying the AC1 was light enough to use on stairs and landings.

One reviewer expected the lighter PencilWash to help with the stair-carrying problem they had with a heavier Dyson wet cleaner.

Pet evidence was positive overall: reviewers described the AC1 as strong for pet owners and dog hair, though one noted pet hair can require post-cleaning brush work.

One review framed the clean/dirty water separation as a useful upgrade for homes with pets or other high-traffic mess sources.

Fine debris pickup on hard floors was positive, with reviewers praising flour and dry-debris cleanup.

Fine-dust and regular hard-floor messes were praised in the hands-on review, which said the PencilWash cleans brilliantly for everyday buildup.

Liquid-system feedback was mixed: the cleaning solution and water filling could be easy or powerful, but solution availability and filling difficulty were concerns.

The liquid system was generally liked for separating clean and dirty water, adding extra moisture for spots, and avoiding smearing dirt.

Kid-friendliness was supported by one reviewer who expected households with children to appreciate the extra cleaning mode.

One review saw the clean/dirty water separation as an upgrade for kids, pets, and high-traffic floors.

Smart and app features were split: automatic dirt/mop detection was praised, while app setup and usefulness were recurring weak points.

App support was limited but somewhat useful, mainly offering instructional and maintenance videos rather than deeper smart features.

Small-space suitability was positive despite dock needs, with reviewers calling it compact or useful for homes lacking space.

Small-space suitability was strong, with repeated praise for apartments, smaller homes, low furniture, and compact storage needs, though large homes were a caveat.

The self-propel feature was usually praised for reducing effort, although one reviewer found the forward momentum required some resistance.

The self-propelled feel was praised in hands-on reviews for helping the cleaner pull itself forward and feel effortless.

Included accessories were useful, especially the cleaning brush and filter, with reviewers appreciating tools that reach tank and roller crevices.

The included dock was viewed positively as an included accessory rather than an extra paid add-on.

A reviewer reacted positively to the built-in tank filter, but filtration evidence was limited to that design impression rather than measured dust containment.

Filter-free operation was mostly viewed favorably, with reviewers linking it to less odor buildup, easier hygiene, and fewer grime or blockage concerns.

Ease of use was generally strong, with reviewers calling the AC1 easy, effortless, and low-labor after setup.

Ease of use was a standout benefit for everyday handling, with reviewers calling it brilliantly simple, effortless, and easy to grab.

Compared with a named alternative, one reviewer saw the AC1 as having the more unique design.

Innovation was widely recognized: reviewers called the form factor highly original, unusually slim, and an engineered solution to a specific cleaning niche.

Area rug handling was negative because multiple reviews warned that the machine is for hard floors, not carpets or rugs.

Build and durability impressions were positive, with reviewers describing the unit as sturdy, thoughtfully designed, and high quality.

The filter-free design was praised as potentially reducing blockages and grime buildup.

Cordless convenience was praised in one review as part of the vacuum being effortless to handle.

Hair-removal channel evidence was a mild concern because pet hair still had to be pulled off after self-cleaning.

Hard-floor hair pickup was positive, with reviewers saying it lifted pet fur and dog hair.

Hair-wrap resistance was mixed because one pet-owning reviewer still had to remove extra hair after self-cleaning.

Onboard storage was praised for keeping the spare filter, cleaning brush, and roller organized.

Packaging was generally positive, with one review reporting no damage and another saying everything was neatly packed.

Sanitizing evidence was skeptical, with one reviewer questioning whether the disinfection mode could literally disinfect.

Support evidence was limited but positive, based on the included one-year warranty giving peace of mind.

Above-floor versatility was poor because one reviewer explicitly said it could not be used on upholstery.
