Roborock Qrevo Edge S5A

Roborock released the Qrevo Edge S5A in 2025 as a more affordable alternative to the flagship Qrevo Edge. The pitch? Nearly the same 18,500 Pa suction power and dual spinning mops, minus the RGB camera and some high-end features, for about $400 less. As of late 2025, it’s selling for $550 to $650 on Amazon, down from the original $999.99 MSRP.

So what exactly do you give up for that price drop? And is the S5A the smarter buy for most households? Let’s break it down.

What Makes the S5A Different from the Standard Qrevo Edge

The S5A trims three key features from its pricier sibling:

No RGB camera - The standard Qrevo Edge includes an RGB camera that works with its Reactive AI obstacle detection. The S5A relies solely on 3D structured light technology (sometimes called “Reactive Tech” in Roborock’s marketing). Both recognize 62 object types, but real-world testing suggests the camera-equipped model handles tricky obstacles slightly better.

Smaller battery - The S5A packs a 5,200mAh battery versus the flagship’s 6,400mAh. Official runtime drops from 240 to 220 minutes in quiet mode, though you’ll likely notice the difference more in larger homes or when running max suction frequently.

Lower threshold climbing - This is the big one. The standard Qrevo Edge features AdaptiLift chassis technology that lets it climb over obstacles up to 40mm (about 1.6 inches). The S5A tops out at 20mm (roughly 0.75 inches). If you have raised thresholds between rooms or particularly thick rugs, this matters.

Everything else stays essentially identical: same 18,500 Pa HyperForce suction, same DuoDivide brush design, same extending FlexiArm side brush, same dual spinning mop pads that wash in 75-degree hot water.

Hardware Breakdown

At 352mm long by 347mm wide and 103mm tall (about 13.9 x 13.7 x 4 inches), the S5A fits under most furniture that clears 4 inches. The robot weighs 3.9 kg (8.6 pounds).

Cleaning System

The DuoDivide main brush splits into two short segments with a gap between them. Hair wraps around the individual segments rather than spanning the full brush width, making it dramatically easier to remove tangles. Users report far less maintenance compared to traditional single-roller designs.

A single extending side brush sweeps debris from edges and corners into the main cleaning path. The FlexiArm design lets it reach further when detecting walls, pulling in dust bunnies that would otherwise hide along baseboards.

The 350ml dustbin is compact, but the bagged auto-empty dock means you’re not handling the contents daily. Roborock claims the 2.7L dock bags last up to 49 days between changes.

Navigation and Sensors

Top-mounted LiDAR handles room mapping and navigation. The 3D structured light system scans for obstacles, recognizing 62 different object types down to 5cm wide and 3cm tall. Shoes, cables, pet bowls, small toys - it should detect and avoid most of them.

That said, obstacle avoidance testing on similar Roborock models shows roughly 66% detection rates in real-world conditions. The S5A will miss things, particularly cords and low-profile items on carpeted surfaces. Plan to robot-proof somewhat before each run.

Battery Performance

The 5,200mAh lithium-ion battery delivers up to 220 minutes of cleaning on quiet mode. More realistically, expect 90 to 150 minutes depending on suction level, mopping intensity, and floor complexity.

Battery efficiency runs about 2 minutes of cleaning per 1% charge, which outperforms most competitors. For a typical 1,500 square foot home, you’ll complete full cleaning cycles without needing a mid-run recharge.

Charging takes roughly 2.5 to 3 hours from empty.

Mopping Performance

Dual spinning pads rotate at 200 RPM with consistent 30-level water flow adjustment. An 80ml onboard water tank supplements the dock’s 4L clean water reservoir.

The mop pads extend slightly during edge cleaning, getting closer to walls and baseboards than non-extending designs. They also lift 10mm when carpet is detected - not as much as some competitors, but enough to prevent wet pads from dragging across low-pile rugs.

Hot water washing at 75 degrees Celsius (167 Fahrenheit) happens back at the dock, followed by 45-degree warm air drying. A dirty water sensor tells the dock when to use fresh rinse water.

For stubborn stains, you may need multiple passes or spot-treatment beforehand. Like most robot mops, this handles maintenance cleaning better than deep-scrubbing dried spills.

The Dock

Roborock’s self-maintaining dock measures 340mm wide by 487mm deep by 521mm tall (about 13.4 x 19.2 x 20.5 inches). It’s not small.

The dock handles:

• Automatic dustbin emptying into 2.7L bags
• Hot water mop pad washing
• Warm air mop drying
• 4L clean and 4L dirty water tank management
• Dirty water detection for smarter rinsing

A removable tray makes cleanup easier when water inevitably drips. Bag replacement runs $20 to $30 for a six-pack, with each bag lasting roughly seven weeks of daily use.

App and Smart Features

The Roborock app provides room-by-room mapping with 3D visualization, cleaning schedules by room, no-go and no-mop zones, and multi-floor map storage. You can set specific suction levels and water flow for different rooms - higher suction in the kitchen, gentler mopping in the bedroom.

Voice control works through Amazon Alexa, and Matter compatibility means integration with broader smart home ecosystems.

Live video monitoring and pet checkup features require the RGB camera, so they’re absent on the S5A. If watching your robot clean remotely sounds appealing, you’ll need the standard Qrevo Edge.

Who Should Buy the S5A

This robot makes sense if you:

• Want premium Roborock cleaning without flagship pricing
• Have low thresholds (under 20mm) between rooms
• Don’t need live camera monitoring
• Prefer a larger home covered in a single battery cycle
• Value hot water mop washing and automated maintenance

Consider the standard Qrevo Edge instead if you:

• Have thick rugs or high transitions between rooms
• Want the RGB camera for better obstacle detection
• Plan to use pet monitoring or remote video features
• Need 40mm threshold climbing

Skip both and look at the Qrevo Curv or S8 series if you need even higher obstacle climbing, faster charging, or other specific features.

Support and Resources

Roborock provides product support through their website at support.roborock.com. The user manual covers setup, maintenance schedules, and troubleshooting for common issues.

The S5A uses standard Qrevo Edge replacement parts for brushes, filters, mop pads, and dust bags. Availability should remain good given Roborock’s continued investment in the Qrevo lineup.
