Compare Roborock Saros Z70 Robot Vacuum and Mop vs Roborock Qrevo Curv Vacuum and Mop

The lifting chassis is a highlight, clearing tall thresholds and helping with rugs; one review notes lift capability can be limited when the arm is deployed.

The adaptive chassis lift/threshold capability is a standout differentiator, helping it clear taller transitions than many robots. A few reviewers suggest real-world limits can be below marketing claims, but it’s still viewed as meaningfully better than average.

Its curved, modern dock and polished styling are frequently described as more living-room-friendly than boxier competitors. Overall sentiment on design is strongly positive.

The app offers deep automation, room rules, zones, and object-handling logic; most praise its flexibility, but a few mention mapping or feature limitations that may improve with updates.

The app is consistently described as feature-rich, with strong automation options (room-by-room settings, scheduling, empty frequency, remop triggers, etc.). Overall sentiment is that the software is powerful without being overly hard to use.

Rug handling benefits from the lift system and mop management, but certain carpets can confuse obstacle avoidance or the arm, leading to hesitation or imperfect behavior.

For mixed flooring, mop lifting and carpet detection are praised for keeping rugs dry while maintaining cleaning coverage; reviewers generally see it as well-suited to homes with area rugs.

Setup is generally straightforward and app-guided, with routines and zones easy to configure once connected.

Setup is described as straightforward: the dock is largely ready out of the box, pairing/mapping is quick, and most complexity comes from exploring app settings rather than assembly.

Battery performance is usually adequate with decent estimation, but some experiences include noticeably shorter runtime and mid-clean recharging.

Battery life and efficiency are rated highly (including strong coverage per charge), making it a good fit for larger homes or multi-room schedules.

Where discussed, the dust system is largely hands-off with long-lasting bags, though at least one reviewer noted the bin can be awkward to remove and handle.

Reviews commonly mention a disposable dust bag in the dock plus an onboard bin; overall feedback is that it reduces dust mess and feels appropriately sized for typical households.

On higher-pile rugs, the chassis lift helps traversal and general pickup is solid, but deep carpet cleaning still is not universally described as category-leading.

Low-pile carpet pickup is frequently described as average for a flagship, with some tests showing mediocre sand pickup compared to top competitors.

Medium-pile carpet pickup is mixed: some tests land around average, while others report solid cleaning but not clearly best-in-class for the premium cost.

Carpet deep-clean performance is rated very strong in testing, placing it near the top tier among vacuum+mop hybrids.

Comparisons to other Roborock flagships often point to better value elsewhere; some reviewers even felt cleaning performance regressed compared to last-gen models due to design tradeoffs.

Controls are primarily app-driven and widely described as intuitive, with useful remote-control options; occasional quirks show up when interacting with the arm or fine-tuning maps.

Controls are generally praised: reviewers cite an intuitive app, useful remote-control features (e.g., pin-and-go), and broad customization. Some note competitor apps can feel more confusing, making Roborock’s UI a relative bright spot.

Corner performance is often strong thanks to extending brushes, helping sweep debris out from edges and tight angles.

Corner cleaning gets frequent praise thanks to an extending side brush, improving reach into tight corners. One stress test notes the side brush can scatter debris in extreme scenarios, but overall corner performance is viewed as above average.

Crevice/groove pickup is noted as a relative weak spot: one review calls it average compared to the robot’s otherwise high-performing hard-floor and carpet results.

A dirty-water / dirt-detection sensor is credited with enabling remop/extra wash behavior, helping prevent spreading grime and improving hands-off cleaning.

Docking and base automation are a defining strength: auto-empty, water handling, and mop washing/drying work well overall, with only occasional hiccups like re-docking retries.

Docking and auto-empty reliability are repeatedly praised: the robot returns consistently, empties well, and handles mop washing/drying and refills with little fuss.

Dock emptying noise is described as relatively quiet for the category, including one report around ~67 dB.

In at least one lab-style comparison, dried-on stain removal ranked near the top of the category, improving with extra passes and pressure.

In at least one standardized test, dried-on stain performance is described as more mid-pack than class-leading—good, but not the standout reason to buy.

Day-to-day ownership is described as low-effort because the dock automates most chores; typical hands-on tasks are water refills/empties and occasional cleaning of the dock tray/consumables.

Edge and baseboard cleaning is often praised, helped by extending brushes or mop edge features that keep cleaning tight to walls and along cabinet kick-plates.

Edge coverage is repeatedly highlighted: an extending mop pad and sweep arm help it clean closer to walls and baseboards than many rivals. Reviewers still wish for true baseboard scrubbing, but edge pickup is considered a strength.

Auto-emptying and sealing reduce mess and day-to-day handling; overall feedback is positive when the base is used as intended.

The bagged emptying system is viewed as clean and convenient, with quiet emptying noted in at least one review and helpful indicators when water tanks need attention.

Floor drying time is generally favorable when mopping, with at least one reviewer calling results quick-drying; actual dryness varies with settings and floor type.

Hair pickup on carpets is a weak spot in at least one measured comparison, pulling down overall vacuuming scores for homes with lots of shedding.

For carpet hair, reviews and pet-hair testing place it among the better performers, though some results suggest two passes may still be needed for the most thorough pickup.

Hard-floor hair pickup is described as excellent in pet-focused testing, with near-perfect results reported.

Tangle resistance is inconsistent: some reviewers mention hair wrapping or brush design downsides, while others highlight active hair-management features that help reduce wrap.

Hair‑wrap resistance is a major highlight: the split/DuoDivide-style roller design earns perfect or near-perfect tangle-test results in multiple discussions. One reviewer still noted minor hair accumulation in certain joints, but overall sentiment remains very strong.

Hard-floor fine dust results are often strong, though stubborn sand or embedded grit can take extra passes depending on settings and floor texture.

Testing-focused reviews describe excellent fine-dust pickup on hard floors, with strong results across small particulate debris.

Large debris pickup on hard floors tends to be very good in testing, with high pickup rates on cereal-style messes.

Large-debris intake is repeatedly described as excellent in testing, handling bigger particles without major issues.

Hot-water mop washing and heated/warm-air drying are consistently praised for hygiene and for keeping mop pads from staying damp between runs.

The Z70 is widely framed as one of the most innovative robot vacuums, mainly due to the arm concept and advanced dock, even by reviewers who do not recommend buying it yet.

The low-profile body is a major advantage, fitting under furniture that blocks taller lidar-tower robots and improving under-furniture coverage.

Most reviewers describe ownership as low maintenance thanks to the dock’s automation, though periodic brush cleaning and checks are still needed in hair-heavy homes.

Maintenance is often framed as low thanks to automation, but owners still need to refill clean water, empty dirty water, replace bags/consumables, and occasionally clean the dock tray and brushes.

Mapping and route planning are a major strength, often described as accurate and efficient; a minority view calls efficiency merely average compared to the very best Roborock pathing.

Lidar mapping and route planning are described as fast and efficient, with organized straight-line coverage and solid room handling/multi-level mapping.

The mechanical arm is widely seen as a cool but immature feature: it can move some lightweight items on hard floors, but reliability, object compatibility, and carpet performance are inconsistent.

The mop system can lift over carpets and, in some configurations, detach pads for vacuum-only runs; reviewers generally describe this as effective.

Mop lifting is frequently cited as effective (often framed around a ~17mm lift), enabling it to vacuum carpets/rugs without soaking them.

Mopping performance is consistently a standout, with strong everyday cleaning and good stain handling; it still cannot fully replace manual scrubbing for heavy, sticky messes.

Mopping is broadly praised—dual spinning pads with adjustable wetness tackle everyday grime and paw prints well, and the extending mop pad improves edge coverage. A few reviewers still give the edge to the best-in-class moppers for heavy stains, but Curv is considered an excellent all‑around performer.

Noise is generally a non-issue, with quiet modes around the low-50 dB range in at least one test and few complaints about loud operation.

Obstacle avoidance is generally excellent for common objects and pets, but cords and certain carpet conditions remain a recurring failure mode in several reviews.

Obstacle avoidance is usually described as good for larger items and many everyday obstacles, but several reviewers call out missed small cables/cords. In cable-heavy rooms, it may snag or stop, so floor prep or no-go zones are recommended.

Overall sentiment is polarized: reviewers love the dock, mopping, slim profile, and navigation, but many rate it down due to the unreliable arm and the very high price.

Across the reviews, Qrevo Curv lands as a top-tier vacuum+mop with strong cleaning results, a highly automated dock, and smart navigation. Praise centers on edge/corner reach and pet-hair handling, while the most common knocks are premium pricing and imperfect cable avoidance.

Pet households benefit from strong object detection and optional monitoring features, but hair pickup and tangling performance varies by surface and may require more brush attention than expected at this price.

Multiple reviews frame it as a great choice for pet owners thanks to strong hair pickup, anti-tangle brush design, and camera/app features (where enabled) for monitoring. Pet homes with lots of cords still need some floor prep.

Price is repeatedly called the biggest downside; multiple reviewers say it is hard to justify versus other premium Roborock models unless you specifically want the full-featured dock and slim chassis.

The price is repeatedly called premium (often framed around a ~$1,600 MSRP), and several reviewers recommend waiting for discounts. When on sale, value is described as far more compelling; a few reviewers question whether camera/chassis-lift extras are worth the upcharge versus cheaper variants or rivals.

Camera-based features (obstacle recognition, remote viewing/voice) bring privacy considerations. Reviews note the camera can be disabled/off by default, and a camera-free variant exists for buyers who prioritize privacy.

At least one reviewer reported visible cosmetic scratching over time, suggesting the finish can show wear in active households.

The self-cleaning dock cycle is consistently praised for hot-water mop washing and drying, reducing odors and day-to-day mop maintenance.

The dock’s self-cleaning base/tray features reduce manual scrubbing, though reviewers still expect periodic cleaning to keep things fresh.

Reviewers expect firmware updates to expand object-recognition libraries and refine the OmniGrip arm; some features or reliability improvements were explicitly described as pending.

When included, the detergent reservoir or dispenser simplifies mop routines and supports more consistent cleaning without manual mixing.

Most reviewers say detergent dosing is manual (add solution to the clean-water tank rather than a dedicated auto-dosing reservoir), while one review lists a detergent capacity/mixing capability. Net takeaway: plan for at least some manual solution handling.

Stuck incidents are relatively rare thanks to lifting and navigation; at least one tester reported it never got stuck during runs.

Adaptive lift helps it clear thresholds and some obstacles, but cable snags and occasional attempts to 'climb' awkward objects can still interrupt runs in some homes.

Across reviews, suction power is described as strong on paper, but real-world pickup is inconsistent; some testers felt it cleaned worse than other Roborock flagships, while others found it fast and effective on daily debris.

Vacuuming performance is described as strong in real homes and on carpets, helped by high rated suction. One evaluation calls out only average airflow/bench suction and weaker performance in tight crevices compared with its overall cleaning results.

Clean and dirty water tanks plus automatic refilling support long stretches between interventions, especially for frequent mopping schedules.

Reviews consistently mention separate clean/dirty water tanks plus onboard water handling that keeps pads wet. Tank refills/empties are a routine task, but capacity and adjustable water use are generally seen as practical for whole-home runs.
