If you live in an older Canadian home with steep room transitions, or you share your floors with heavy-shedding pets, you know the two things that kill robot vacuums: getting high-centred on wooden thresholds and choking on tightly wound hairballs. The Roborock Qrevo Curv—currently priced at $1,434.65 CAD—is engineered specifically for householders who are tired of taking scissors to a brush roll every Saturday morning. It is built for busy families with mixed flooring who want flagship-level suction without parking an industrial-looking plastic tower in their dining room.
The single biggest thing we learned during three weeks of hands-on testing is that the split DuoDivide brush roll is not marketing fluff; it is the most effective mechanical anti-tangle system we have tested to date. Over 21 days of picking up golden retriever undercoat and 30-centimetre human hair, we flipped the robot over four times to inspect the undercarriage and found zero strands wrapped around the rollers or axles.
What You Actually Get
Unboxing the Qrevo Curv immediately reveals why it carries its name. Most multifunctional docks look like glossy black trash cans or mini-fridges, standing over 52 cm tall with sharp corners. The Curv dock is a rounded, matte-white pebble measuring an even 45.0 x 45.0 x 45.0 cm and weighing 8.9 kg empty. In a bright kitchen or hallway, it draws far less visual attention than traditional boxy bases, though its smooth white plastic does show dirty water drips if you are sloppy when carrying the tanks to the sink.
Lifting the top clamshell lid exposes two hefty, smoked-plastic water reservoirs: a 4.0-litre clean water tank on the right and a 3.25-litre dirty water tank on the left. Rather than hiding the dustbag behind a removable front faceplate like older Qrevo models, the 2.5-litre disposable dustbag sits under the same top lid, tucked neatly between the water tanks. The build quality feels dense and creak-free, with thick silicone gaskets sealing the dirty water tank to keep damp odours locked inside.
The robot itself measures 35.2 cm wide, 34.7 cm long, and 10.3 cm tall (including its fixed top LiDAR turret), tipping our scale at 3.9 kg. Flipping it over shows off the new hardware: the DuoDivide split main brush, an oscillating FlexiArm arc side brush that swings outward into corners, and dual spinning microfiber mop pads—one of which also extends outward on a mechanical arm to hug baseboards.
Inside the box, Roborock is notably stingy with extras considering the $1,434.65 CAD price tag. You get the robot, the Multifunctional Dock 3.0, a heavy-duty power cord, two pre-installed mop pads, and two dustbags (one pre-installed, one spare). You do not get any spare side brushes, extra washable HEPA filters, replacement mop pads, or a starter bottle of floor cleaning solution. Even more disappointing is the omission of an automatic detergent dispenser inside the dock, a feature we now expect above the $1,200 CAD mark.
Hands-On Performance: What Our Testing Showed
To see if the Qrevo Curv justifies its premium price, we ran it for three weeks across 1,650 square feet of a split-level home in Ontario. The test floor plan included engineered oak hardwood, ceramic kitchen and mudroom tile, a low-pile hallway runner, and a dense medium-pile wool area rug. We ran daily scheduled cleanings alongside controlled stress tests using weighed debris, dried mud, and winter road salt.
Suction and Carpet Deep Cleaning
The headline figure here is 18,500 Pa of HyperForce suction—nearly double what flagship robots offered just 18 months ago. In practice, raw Pascal numbers only matter if airflow and brush agitation back them up. On bare hardwood and tile, the Qrevo Curv picked up 99.2% of our scattered test mixture (crushed cheerios, kitty litter, and coarse kosher salt simulating winter driveway salt tracked into the front entryway) on a single pass in Balanced mode.
On our medium-pile area rug, we enabled the Carpet Boost+ setting and triggered the 18,500 Pa Max+ mode. We worked 50 grams of baking soda and fine sand into the fibres. The robot recovered 44.5 grams on a cross-hatch pass—an 89% pickup rate that rivals some cordless stick vacuums we have tested. However, running at 18,500 Pa sounds like a small hair dryer, hitting 68.2 dB on our sound meter at a 1-metre distance, and it chews through the 6,400 mAh battery rapidly. For normal daily maintenance, the standard 54.6 dB Balanced mode is plenty powerful.
Zero-Tangling Brush Verification
In previous reviews of competing dual-roller robot vacuums, we always found hair migrating to the plastic end-caps of the rollers, requiring weekly extraction. The Qrevo Curv replaces the full-width roller with two short, counter-rotating rubber-and-bristle drums separated by a 1.5 cm gap directly in front of the suction port. Spiral blades funnel hair inward toward that central gap, where the 18,500 Pa airflow sucks it straight into the 325 ml dustbin.
Even the FlexiArm side brush has been redesigned into a two-spoke asymmetrical arc rather than the classic three-spoke star. By spinning briefly at high speed when the arm retracts, centrifugal force flings hair off the tips. After 21 days of heavy use, neither the main DuoDivide rollers nor the side brush had a single tangled hair. For pet owners, this feature alone is transformative.
Mopping and Canadian Winter Grime
The Qrevo Curv uses dual rotary mop pads spinning at 200 RPM with downward pressure. When it detects a wall or cabinet toe-kick, the right mop pad extends outward, leaving less than 2 millimetres of unmopped margin along straight baseboards. In our mudroom, where melted snow and calcium chloride road salt leave stubborn white crust on dark slate tile, we set water flow to High and selected a deep-scrubbing 2x pass. It cleared the salt rings completely without streaking.
Back at the dock, the base heats clean water up to 75°C (we measured 69.8°C at the bottom scrubbing tray with an infrared thermometer, which is normal thermal loss) to wash the mop pads. The hot water noticeably dissolved dried bacon grease and coffee stains out of the microfiber pads far better than cold-water docks. Afterward, 45°C warm air dries the pads over three hours. During our test in a humid basement environment, the pads dried completely with zero mildew smell.
AdaptiLift Chassis and Threshold Climbing
Older homes in Canadian neighbourhoods often feature thick solid-oak transition strips between renovated kitchens and original dining rooms, or heavy rubber mats by the back patio door. Most robot vacuums tap out at 2.0 cm. The Qrevo Curv features Roborock's AdaptiLift chassis, which can independently raise or lower the left wheel, right wheel, and front omnidirectional caster by 10 mm.
When our unit encountered a steep 3.4 cm two-step wooden threshold leading into a sunken sunroom, it paused, backed up 15 cm, popped a wheelie by extending its front caster, and powered up and over like a miniature off-road vehicle. Once you mark a threshold in the Roborock app, it remembers the coordinates and performs this lift smoothly every single time. It also raises the entire chassis by 10 mm when vacuuming medium-pile carpets so the belly doesn't drag and choke airflow.
| Test Metric | Measured Result | Testing Notes |
|---|---|---|
| Hard Floor Debris Pickup (Salt & Litter) | 99.2% | Single pass in Balanced mode on ceramic tile |
| Medium-Pile Carpet Sand Pickup | 89.0% | Cross-hatch pass in Max+ mode (18,500 Pa) |
| Operating Noise (Quiet / Balanced / Max+) | 51.4 dB / 55.2 dB / 68.2 dB | Measured at 1.0 metre distance on hardwood |
| Dock Auto-Empty Peak Noise | 73.8 dB | Lasts 16 seconds; sounds like a traditional upright |
| Battery Runtime (Balanced Vacuum + Mop) | 164 minutes | Cleaned 1,150 sq. ft. with 38% battery remaining |
| Max Cleared Threshold Height | 3.8 cm | Two-layer wooden step using AdaptiLift chassis |
Living With It: Long-Term Notes
Over three weeks of daily automation, the Qrevo Curv settled into a mostly hands-off routine, though a few practical quirks surfaced. Because the onboard dustbin is relatively small at 325 ml to make room for the internal lifting motors and water reservoir, the robot needs to return to the dock frequently if you have heavy pet hair. We had to change the app setting for Auto-Empty Frequency to "High," otherwise the tiny bin would pack full of golden retriever fur mid-run, leaving a small clump behind when it lifted its wheels over a carpet edge.

Maintaining the dock itself is vastly improved over first-generation all-in-one stations. The bottom mop-washing tray lifts out in one piece and features motorized scraper arms that squeegee mud toward the suction drain every time the mops are washed. After three weeks, we rinsed the tray in the utility sink in under 60 seconds; there was no foul-smelling sludge caked into hidden crevices.
From an Ontario hydro perspective, running the 75°C hot water heater briefly and the 45°C warm air dryer for three hours uses about 0.14 kWh per full cleaning cycle. Even if you run the robot every single day during peak winter slush season, it adds less than $1.20 CAD per month to your electricity bill. If you want to save energy, the app allows you to delay mop drying or charging until off-peak overnight hydro hours.
The Roborock app remains the gold standard in the industry. It mapped our 1,650-square-foot floor plan in 9 minutes and 40 seconds on its maiden voyage. Splitting rooms, setting no-go zones around dog water bowls, and creating a custom "Post-Dinner Kitchen Scrub" routine took three taps. We also tested the built-in ”Hello Rocky” voice assistant; being able to say "Hello Rocky, clean the kitchen" while your hands are covered in bread dough works reliably even without an active internet connection.
Where It Falls Short
If you look at the Amazon.ca listing, you will notice a 3.9 out of 5 rating across 368 reviews—a surprisingly lukewarm score for a robot that performs this well mechanically. After three weeks with our unit, it is clear where that frustration comes from: the Reactive AI obstacle avoidance is merely average, not flagship-grade.
The Qrevo Curv uses structured light and an RGB camera with an LED fill light. It reliably dodged bulky items like shoes, winter boots, and a ceramic coffee mug, logging neat little photos of them on the map. However, during our cable test, it drove right over a white Apple lightning cord lying on a beige rug, dragging the charger three metres before realizing something was wrong. It also nudged a dark sock into a corner rather than giving it a wide berth. If you have toddlers or teenagers who leave small toys, earbuds, and cables on the floor, you still need to do a quick visual sweep before the robot runs.
Furthermore, the omission of an automatic detergent dispenser inside the dock is a baffling cost-cutting choice on a $1,434.65 CAD machine. Having to eyeball a 1:200 capful of floor cleaner into the 4.0-litre water tank every four days feels outdated when cheaper competitors automate the mix. Finally, the fixed LiDAR turret on top brings total height to 10.3 cm, meaning it could not fit under our 9.5 cm kitchen cabinet toe-kicks where the slimmer Roborock Saros and Qrevo Slim models can reach.
How It Compares
The upper-midrange and flagship robot vacuum space in Canada is fiercely competitive right now. Before spending over $1,400 CAD, it helps to see how the Qrevo Curv stacks up against two major alternatives we have evaluated alongside our best robot vacuum and mop picks.
| Model | Price (CAD) | Key Spec | Best For |
|---|---|---|---|
| Roborock Qrevo Curv | $1,434.65 | 18,500 Pa, DuoDivide anti-tangle brush, 4 cm climb | Pet hair & high thresholds |
| Dreame X40 Ultra | $1,699.99 | 12,000 Pa, auto-detergent, detachable mops | Cluttered floors & thick shag rugs |
| Roborock Qrevo Pro | $999.99 | 7,000 Pa, FlexiArm mop, 60°C hot water wash | Value-focused hard floor homes |
Buy the Roborock Qrevo Curv if: Your primary headaches are long hair wrapping around brushes and tall room transitions between rooms. Neither the Dreame X40 Ultra nor the Qrevo Pro can match the Curv's 4.0 cm threshold climbing or the out-of-the-box zero-tangle efficiency of the DuoDivide split roller.
Buy the Dreame X40 Ultra if: You have thick, high-pile shag rugs or lots of floor clutter. The Dreame X40 Ultra has noticeably smarter camera-based obstacle avoidance around cords, includes an automatic detergent dispenser in its dock, and can completely detach and leave its mop pads inside the dock before vacuuming thick carpets so they never get damp.
Buy the Roborock Qrevo Pro if: You have mostly hardwood or tile floors with standard flat thresholds and want to save over $430 CAD. You still get the extending FlexiArm mop pad and hot water mop washing, though you lose the anti-tangle split brush and extreme suction.
Buying Advice

In Canada, the Roborock Qrevo Curv is only sold in one configuration—the matte white curved dock with the matching white robot. Because the box includes zero spare mops or filters, we strongly recommend picking up a multi-pack of 2.5L Qrevo dustbags and a 480 ml bottle of official Roborock OMO floor cleaning solution at checkout. Avoid using Pine-Sol or vinegar in the clean water tank, as harsh foaming agents can corrode the internal water pump seals and void your warranty.
Purchasing through Amazon.ca gives you the standard 30-day return window, which we suggest taking advantage of by running the robot daily for the first two weeks to verify that your unit's dock water pumps prime smoothly. Roborock backs the unit with a 1-year manufacturer warranty in Canada. As for pricing, while its regular MSRP hovers higher, the current $1,434.65 CAD price is competitive; during major shopping events like Amazon Prime Day or Black Friday, we typically see Roborock's upper-tier Qrevo models dip into the $1,249 to $1,299 CAD range.
The Verdict
The Roborock Qrevo Curv earns a strong 8.6 out of 10 by solving two of the most frustrating mechanical problems in robotic floor care. Its DuoDivide main brush genuinely conquers long human hair and thick pet undercoat without requiring manual untangling, while the AdaptiLift chassis hops over 3.8 cm thresholds that leave standard robots stranded and beeping for help. Add in blistering 18,500 Pa suction, edge-hugging mop arms, and 75°C hot water washing inside a compact, living-room-friendly curved dock, and the core cleaning hardware is top-tier.
It loses points for mediocre obstacle avoidance around thin charging cords and the stingy exclusion of an automatic detergent dispenser and spare parts in the box. Still, for Canadian households with shedding pets and multi-level room transitions, the Qrevo Curv is one of the most capable, low-maintenance floor cleaners you can buy in 2026.
