Main trade-off
Roborock Qrevo Edge S5A
S5A is a distinct version of Qrevo Edge. Do not assume it includes the standard Edge's AdaptiLift chassis.
Head-to-head
Qrevo Edge S5A vs Qrevo Curv: S5A saves 110 mm of dock width but needs more depth
The short answer
Choose the Qrevo Edge S5A when station width is tight and your floors do not require the Curv's lifting chassis. Choose the Qrevo Curv for AdaptiLift. The S5A dock is 110 mm narrower, but 37 mm deeper. Do not confuse the S5A with the standard Qrevo Edge, which has different chassis hardware.
Before you choose
The reasoning and the trade-offs
The S5A dock is 24.4% narrower
A narrow gap can favor S5A, provided the extra depth does not block a walkway.
What this is based on
(450 - 340) / 450 × 100 = 24.44%. Station widths are 340 and 450 mm, with depths of 487 and 450 mm.
Main trade-off
Roborock Qrevo Curv
Independent testing found mediocre small-obstacle avoidance.
Roborock Qrevo Edge S5A
- Choose it for
- You have a narrow station location with enough depth.
- Your floors are mostly level and you do not need AdaptiLift.
- Main trade-off
- S5A is a distinct version of Qrevo Edge. Do not assume it includes the standard Edge's AdaptiLift chassis.
Roborock Qrevo Curv
- Choose it for
- Thresholds are the reason you are comparing these models.
- A 450 mm square dock fits your room better than a narrower, deeper one.
- Main trade-off
- Independent testing found mediocre small-obstacle avoidance.
About this comparison
The Qrevo Edge S5A has a narrower dock but lacks the Curv's AdaptiLift chassis. Compare station space, robot height and threshold requirements.

What matters in practice
The differences that matter
The S5A dock is 24.4% narrower
A narrow gap can favor S5A, provided the extra depth does not block a walkway.
How we reached this conclusion
(450 - 340) / 450 × 100 = 24.44%. Station widths are 340 and 450 mm, with depths of 487 and 450 mm.
Its base footprint is about 18.2% smaller
S5A occupies less rectangular floor area, even though it is deeper. That does not include space to service either station.
How we reached this conclusion
340 × 487 = 165,580 mm² and 450 × 450 = 202,500 mm². The area reduction is 18.23%.
A similar name hides a real chassis difference
The standard Edge's climbing claims must not be applied to Edge S5A. Curv is the supported choice here when AdaptiLift is the requirement.
How we reached this conclusion
Roborock's Edge-series comparison marks AdaptiLift as exclusive to the standard Edge. The Curv specification separately includes AdaptiLift.

What you give up
Every choice has a cost
If you choose Roborock Qrevo Edge S5A
- Hair-resistant brush construction reduces one maintenance job but does not establish stronger pet-hair pickup.
If you choose Roborock Qrevo Curv
- The split brushroll struggled with pet hair in independent testing.
What matters in practice
How to make the call
Measure a rectangle, not just a gap
A 340 mm dock sounds compact until its 487 mm depth projects into a walkway. Mark the intended station footprint on the floor. Leave additional room for the robot to approach and for you to remove tanks and clean the tray.
Read the suffix on the listing
Edge and Edge S5A are not interchangeable names. The S5A drops AdaptiLift, so a review of the standard Edge can create the wrong expectation about threshold handling. Match the complete model name on the Amazon page before buying.
Use the smaller body advantage realistically
Five millimeters can matter at a tight furniture opening, but it is a much smaller difference than a retractable-tower design offers. If the gap is around 100 mm, measure carefully rather than assuming the 98 mm robot has enough practical margin.
What this comparison cannot tell you
- Manufacturer specifications describe the hardware. They do not replace a shared cleaning test or guarantee performance on every floor.
