Compare Dreame R20 Cordless Vacuum vs Shark PowerDetect Speed

Carpet hair pickup was a weakness in the pet-shelter test, leaving a lot of hair behind on carpet and thick rugs.

The vacuum pulled a surprising amount of hidden cat hair from rugs in a short pass, making carpet hair pickup a clear strength.

Cyclone feedback was mixed because thicker debris could stay stuck on the cyclone assembly despite removable parts.

Carpet testing produced a pronounced sense of cyclonic pull, helping lift embedded debris and pet hair from rugs.

Battery and charging drew mixed-to-positive evidence: removable batteries and long claimed runtime helped, but charging design and real-world drain varied.

Eco and Auto modes can cover routine quick cleaning, but Boost runtime falls to roughly 10–13 minutes and a full recharge can take five to six hours.

Storage stability was criticized because the R20 does not stand on its own and relies on wall-mounted storage.

The folding body and slimmer dock help with storage, but the Clean & Empty base can still feel bulky in a cramped apartment. One tester also disliked the head locking upright during normal backward motion.

Innovation feedback was mixed: the R20 was not seen as radically new, but reviewers liked that it combined power and accessories well.

The refined detection system, reverse cleaning, Reveal lighting, flexible wand, and self-emptying dock create a notably polished package, even though similar smart features are becoming more common.

Runtime evidence was mixed but generally favorable: several praised long life, while high-power modes drained quickly and some tests fell short of claims.

Runtime is acceptable in Eco or Auto mode but poor at maximum power, where several testers measured only about 10–13 minutes. Long recharge times magnify that limitation.

Onboard storage was convenient but imperfect because docks could not hold every major accessory or lacked enough storage points.

Integrated dock notches keep the included tools organized and easy to find, a small detail that testers appreciated.

LED and headlight evidence was mixed: blue lights were helpful, but weaker than some rivals and absent from the soft floorhead.

The adaptive headlight switches to blue on hard floors and white on carpet. Its blue beam exposes dust especially well, though Dyson’s green laser remains the benchmark for some testers.

Heavy-duty suitability was limited by small-bin concerns, clogging, and weaker results in busy, messy homes or repeated-pass situations.

Short maximum-power runtime makes it a poor fit for long, uninterrupted whole-home deep cleans. It works better as a quick-cleaning cordless companion than a heavy-duty sole vacuum.

Emptying was mixed: some found it effortless with minimal blowback, while others had to reach in or manage dust shooting out.

The self-emptying dock sharply reduces direct dust contact and daily bin chores. Periodic dock emptying can still release a cloud because the system is bagless.

Small-space cleaning was praised because the R20 could reach tight spaces and narrow gaps that other vacuums missed.

The vacuum itself suits small homes and quick apartment cleaning, but the auto-empty dock requires more floor space than a simple wall charger.

Upholstery and above-floor pickup were strong, especially with the mini motorized brush on sofas, pet beds, and fabric surfaces.

Above-floor results are mixed: upholstery tools work well on ordinary furniture and car areas, but dense pet hair and a loosely attached dusting brush expose limitations.

Edge and baseboard evidence was positive in one test, where the head cleaned right up to the wall when approached head-on.

Edge cleaning can be excellent on high power, but another test found the main head left enough debris to require the crevice tool. Results appear dependent on power setting and debris type.

Large-debris intake was mixed: some tests praised smooth pickup, while others found scattering, stuck cereal, or leftover debris.

Large crumbs, rice, litter, and other debris are generally swallowed quickly on hard floors. Some rice scattered in one test, but overall intake remained strong.

Ownership-cost evidence centered on the removable battery: useful in concept, but additional batteries were described as expensive.

A replacement battery was difficult to find at launch, and older Shark batteries suggest a spare could add a meaningful ownership cost.

The bin earned mixed reactions: capacity and dust storage were acceptable, but smaller size, stuck debris, and frequent emptying were recurring caveats.

The transparent onboard bin makes each clean easy to inspect, and pairing it with the larger self-emptying dock reduces hands-on emptying.

The accessory package was usually treated as a strength, especially the soft roller, flex adapter, mini brush, and broad tool selection; one combination tool drew criticism.

Attachment opinions vary by package and region. Some testers found the tools useful and well chosen, while others considered the bundle sparse for the price or wanted a stronger motorized pet tool.

Setup was described as easy, with straightforward assembly, a less-fiddly mount, and parts that snap into place cleanly.

Assembly is quick and self-explanatory, with the dock and vacuum components clicking together in only a few minutes.

Comparative reviewers positioned the R20 as a stronger-featured, longer-running, better-value option, while still conceding some rivals beat it on carpet.

The Speed is lighter, more convenient, and usually cheaper than premium Dyson alternatives, but it does not always match their peak suction or illumination. The original PowerDetect can also clean carpets more thoroughly.

Area-rug handling varied, from strong medium-pile rug pickup to weaker mat and shag-rug results.

Most testers reported excellent rug handling and powerful embedded-debris pickup. One direct comparison found the Speed left substantial dust behind versus the original PowerDetect, making carpet performance the clearest point of disagreement.

Under-furniture cleaning was improved by the flexible adapter and bendy connector, though one reviewer found turning hard when reaching far.

The hinged wand is a standout, letting the head reach under beds, sofas, and low cabinets without kneeling. Most testers found it highly useful, though one noted the hinge can feel slightly awkward.

Pet-hair evidence is split: some reviewers praised pet-hair handling, while carpeted pet homes drew cautions and lower scores.

The main brush handled pet hair and resisted tangles well, but the included pet attachments were less convincing and the strongest motorized option may cost extra.

Build quality was mostly described as sturdy and premium, with some concerns about specific accessories feeling less robust.

The vacuum feels sturdy enough for routine household cleaning despite relying heavily on molded plastic. It does not feel truly premium, but it also avoids feeling cheap.

Ease of use was generally positive, with reviewers praising simple operation, automatic mode, easy cleaning, and comfortable daily handling.

Simple controls, automatic suction, flexible reach, and self-emptying reduce both effort and cleaning time. The vacuum is particularly convenient for frequent short sessions.

The display, lock button, and simple controls were praised, but the sensitive trigger and some handle ergonomics created mixed control feedback.

The two-button controls and color display are straightforward and useful. Minor complaints include moving the dirt indicator away from the floorhead and showing battery life as an icon instead of a percentage.

Weight was consistently praised or considered manageable, supporting easier one-handed use, stairs, and longer cleaning sessions.

At roughly seven to eight pounds, the Speed is lighter and easier to handle than the original and several premium rivals. Some users may still find it chunky during longer sessions.

Value was one of the strongest themes when discounted or compared with premium alternatives, though some reviewers still called it expensive.

Reviewers consistently viewed it as strong value for near-flagship cleaning and an auto-empty dock. It is still a $500-class purchase, but generally costs less than comparable Dyson setups.

Noise impressions ranged from pleasantly quiet to irritating, with several reviewers noting whine or higher-pitched sound in stronger modes.

The vacuum is clearly audible at higher power, but its running noise is not unusually harsh for a cordless model. The auto-empty burst is brief.

Packaging was praised for being organized and secure with no loose or rattling parts.

Packaging is compact and largely recyclable, using paper and cardboard instead of substantial single-use plastic or foam.

Filtration and dust containment were generally praised for trapping fine dust, though one reviewer preferred true HEPA for allergy sufferers.

The washable HEPA filter provides strong dust containment and long-term air quality, although it must be washed and fully dried on schedule.

Handheld use was useful for shelves, keyboards, tabletops, and above-floor cleaning without feeling overly heavy.

The body converts effectively to handheld mode for spot cleaning, though the limited accessory selection can restrict specialized handheld tasks.

The tool-release system was praised for click-in setup and easy button-based removal.

Large release buttons make the attachments quick and simple to connect or remove.

Maintenance was mostly easy thanks to removable washable parts, though reviewers still noted periodic cleaning and best practice after use.

The auto-empty dock reduces daily maintenance, but the washable filter still needs periodic cleaning and complete drying to avoid odors.

Reviewers consistently found suction strong for the class, especially on hard floors and daily cleaning, though some carpet and heavy-debris tests exposed limits.

Most testers praised the strong suction and excellent everyday pickup, especially on hard floors. One comparative test found the slimmer Speed noticeably weaker than the original on carpet.

Debris illumination was widely valued for revealing hidden dust and making cleaning more purposeful, though effectiveness varied by head and conditions.

The blue hard-floor light reveals fine dust very effectively and is a noticeable improvement over Shark’s older white light. Some testers still prefer Dyson’s green laser, and one questioned whether blue UV adds much over standard lighting.

Floorhead design earned praise for steering and wall pickup but also criticism for wiggle, limited angles, and less mobility in some heads.

The single multi-surface floorhead avoids head swaps and performs well in most tests. Its main tradeoffs are weaker deep carpet extraction than the original dual-brush head and occasional upright locking.

Hard-floor fine-dust pickup was strong in reviewer tests, with fine flour and dust collected cleanly on hard surfaces.

Hard-floor fine-dust pickup is consistently strong, especially at full suction, and the blue illumination helps reveal particles that would otherwise be missed.

Handling was mostly strong thanks to light feel and smooth maneuvering, although reach-under turns and some floorhead wiggle limited it.

The lighter, balanced body generally steers smoothly and is easier to handle than the original. A recurring upright-lock issue in one test can interrupt backward passes.

Design impressions were positive overall, with reviewers calling out a sleek, premium-looking body, clean finish, and attractive carbon-style elements.

The slimmer shape and restrained metallic finishes look polished rather than appliance-like, with the Luxe colors earning especially strong praise for fitting into home decor.

Versatility was a clear strength due to the flexible adapter, multiple floorheads, handheld options, and broad attachment set.

The combination of multi-surface pickup, handheld conversion, flexible reach, automatic suction, and auto-emptying makes it useful for varied quick-cleaning jobs.

Smart dirt detection and auto suction adjustment were usually praised as useful, visible, and not gimmicky.

Automatic dirt, floor, edge, and direction detection is one of the strongest features, adjusting suction with little user input. Testers found it responsive and genuinely useful in everyday cleaning.

Hair-wrap resistance was a strong point, with multiple reviewers reporting clean rollers and no tangles after hair pickup.

The anti-wrap design handles long and pet hair unusually well, leaving little buildup on the main brush. It is not perfectly tangle-free, but it requires less manual cutting than most rivals.

Overall opinion leaned positive, especially for hard floors, value, suction, and ease, but some reviewers framed it as best for lighter-duty homes.

The overall reception is strongly positive for quick daily cleaning, hard floors, and convenience. The main reservations are weak maximum-power endurance and inconsistent carpet performance versus the original model.

Airflow blowback evidence was mixed: one reviewer praised minimal blowback, another liked side vents, and another warned dust could shoot out.

A warning light clearly indicates when the dock bin needs attention, reducing guesswork around emptying.

High-pile and shag-rug pickup was weaker, with reviewers reporting push resistance or many passes despite strong suction.

Low-pile carpet pickup was acceptable but not effortless, requiring two passes and edge work in one test.

Medium-pile and general carpet performance ranged from very strong in one pass to merely average or behind Dyson in comparative tests.

Clogging was a recurring weakness in high-volume debris or hair/dust situations, reducing efficiency or requiring blockage clearing.

The cordless format is especially convenient for fast spot cleaning when pulling out a larger wired vacuum would be excessive.

Groove and gap pickup was strong, including clean wooden-floor grooves and gaps up to 0.3 inches in testing.

The dock’s 20–30 second emptying cycle is conspicuously loud, even with Quiet Mode, though some testers considered it typical for self-emptying vacuums.

Hard-floor hair pickup was excellent in the supporting test, with pet hair collected in one pass without fail.

One test found the handle became quite hot during sustained high-power use, which could make longer intensive sessions uncomfortable.

The relatively low-profile floorhead slips into tighter spaces and complements the flexible wand for reaching beneath furniture.

Durability confidence was mixed because robust plastics were offset by concerns about carbon-tube flex, less-sturdy accessories, and heat management.

Docking is straightforward and immediately triggers emptying and charging. The slimmer simplified base was preferred to the older design, though its footprint still matters in small rooms.

Full-power pickup works in both forward and reverse passes, reducing the need to repeat the same path.

Stair suitability was supported by the vacuum's lower weight and ease of carrying upstairs.

Despite strong carpet suction, one tester did not experience the head jamming the way a competing high-suction model did.

Surface safety evidence was positive, with wheels described as safe on delicate hard floors.
