The catch
Roborock Qrevo Edge S5A
Don't assume S5A shares the standard Edge's AdaptiLift chassis, because it is a distinct version of Qrevo Edge.
Side by side
Qrevo Edge S5A vs Qrevo Curv: The dock on S5A is 110 mm narrower, though it takes up more depth
Quick verdict
When station width is tight and your floors don't need the Curv's lifting chassis, go with the Qrevo Edge S5A. Go with the Qrevo Curv if you want AdaptiLift. The S5A dock is 110 mm narrower but 37 mm deeper. Don't mix up the S5A with the standard Qrevo Edge, whose chassis hardware is different.
Before you buy
Why, and what it costs you
S5A's dock is 24.4% slimmer
For a narrow gap, S5A can be the better choice, as long as its extra depth does not block a walkway.
Where this comes from
(450 - 340) / 450 × 100 = 24.44%. The stations are 340 and 450 mm wide and 487 and 450 mm deep.
The catch
Roborock Qrevo Curv
Small-obstacle avoidance was only mediocre in independent testing.
Roborock Qrevo Edge S5A
- Why pick it
- The spot for the station is narrow but deep enough.
- Most of your floors are level, so AdaptiLift is unnecessary.
- The catch
- Don't assume S5A shares the standard Edge's AdaptiLift chassis, because it is a distinct version of Qrevo Edge.
Roborock Qrevo Curv
- Why pick it
- You are comparing these models because of thresholds.
- Your room suits a 450 mm square dock better than a narrower, deeper one.

What this page compares
A narrower dock comes with the Qrevo Edge S5A, but it has no AdaptiLift chassis like the Curv's. Compare station space, robot height and threshold requirements.

Differences you will notice
S5A's dock is 24.4% slimmer
For a narrow gap, S5A can be the better choice, as long as its extra depth does not block a walkway.
How we worked this out
(450 - 340) / 450 × 100 = 24.44%. The stations are 340 and 450 mm wide and 487 and 450 mm deep.
The footprint of its base is smaller by about 18.2%
Although it is deeper, S5A takes up less rectangular floor area. Room for servicing either station is not counted.
How we worked this out
340 × 487 = 165,580 mm² and 450 × 450 = 202,500 mm². That works out to an 18.23% reduction in area.
Behind a similar name sits a real chassis difference
Do not carry the standard Edge's climbing claims over to Edge S5A. If AdaptiLift is what you require, Curv is the supported choice.
How we worked this out
In Roborock's Edge-series comparison, AdaptiLift is marked as exclusive to the standard Edge. The Curv specification, separately, lists AdaptiLift.
Option A
Roborock, Qrevo Edge S5A

- Cleaning edges where room transitions are ordinary
Facts we checked
- Suction rated by the manufacturer at 18,500 Pa
- FlexiArm side brush and DuoDivide main brush
- Automatic dust emptying, plus mop washing in hot water and drying with warm air
Option B
Roborock, Qrevo Curv
Qrevo Curv
Heated dock washing, strong hard-floor pickup and capable mopping make this a mature upper-premium choice.
- Best for
- Chassis lift with heated dock care
Facts we checked
- Suction rated by the manufacturer at 18,500 Pa
- Dock washes mops at 75°C

| Station width | 340 mm | 450 mm | S5A is 110 mm slimmer side to side. |
| Station depth | 487 mm | 450 mm | Front to back, the narrower S5A station sticks out 37 mm more. |

Trade-offs
What each pick costs you
With Roborock Qrevo Edge S5A
- A hair-resistant brush saves you one maintenance job, but that does not establish stronger pet-hair pickup.
With Roborock Qrevo Curv
- Independent testing showed the split brushroll having trouble with pet hair.
Decision guide
How to decide
Measure a full footprint as well as a gap
A 340 mm dock sounds compact, but its 487 mm depth can stick out into a walkway. Mark where the station would sit on the floor, and leave extra room for the robot to approach and for you to pull the tanks and clean the tray.
Check the suffix in the listing
Edge and Edge S5A are different models, and the names are not interchangeable. Since the S5A drops AdaptiLift, a review of the standard Edge can set the wrong expectation about threshold handling. Before buying, match the complete model name on the Amazon page.
Keep the smaller body advantage in perspective
A tight furniture opening can make five millimeters count, yet that is a far smaller difference than a retractable-tower design gives you. If the gap is around 100 mm, measure carefully and do not assume the 98 mm robot has enough practical margin.
What this page can’t tell you
- Specs from the manufacturer describe the hardware only. They are no substitute for a shared cleaning test and guarantee nothing about performance on every floor.
By the numbers
What the data shows
What we found across the robot vacuums we compare, plus the checked facts behind each finding.
How many fit
None of the 52 models checked meets all of “I have no room for a large wash station”, “Tall thresholds sit between my rooms”, and “I care about mopping as much as vacuuming”, so the pick goes to the closest practical compromise.
0 models fit, out of 52 checkedShow the facts and the math
How we countedThe count uses each product's current fit ratings for “I have no room for a large wash station”, “Tall thresholds sit between my rooms”, and “I care about mopping as much as vacuuming”. A need with no documented match is not counted.
