Roborock Qrevo S

The Bottom Line

The Roborock Qrevo S presents a curious paradox: it cleans better than robots costing $200-400 more while simultaneously failing at tasks you’d expect from any modern robot vacuum. If you’ve got hardwood floors and a tidy home, this $699-799 machine punches well above its weight. But live with pets, dark rugs, or a tendency to leave socks on the floor? You’ll fight this robot more than it fights dirt.

Released in mid-2024, the Qrevo S slots below the pricier Qrevo MaxV ($999) and Qrevo Master ($1,199) in Roborock’s lineup. It delivers the same 7,000 Pa suction as the MaxV—impressive for the price—and pairs that with a full-featured dock that empties its own dustbin, washes and dries its mop pads, and refills its water tank. That’s a lot of automation for under $800.

What Makes It Shine

Hard Floor Performance

On hardwood, tile, and laminate, the Qrevo S absolutely excels. Testing shows it picks up over 96% of debris on hard surfaces, outperforming even its more expensive siblings in practical cleaning scenarios. The single rubber brush does an excellent job with everything from fine dust to rice and cereal, while the dual spinning mop pads scrub at 200 RPM to tackle dried-on stains.

The mopping system scored 116 out of 176 on dried stain tests—comparable to the $999 MaxV despite costing $200 less. Water flow is adjustable across 30 levels, giving you precise control over how wet your floors get.

Mapping and Navigation

First-time mapping takes roughly five minutes, making it one of the fastest robots tested. The LiDAR navigation plots efficient row-by-row paths, learns your home’s layout over time, and supports up to four floor maps for multi-story homes. The app offers extensive customization: virtual barriers, no-go zones, no-mop zones, room-specific suction and water settings, and scheduling down to individual rooms.

Battery Life

A 5,200 mAh battery delivers around 180 minutes on balanced settings, or 240+ minutes in quiet mode. Real-world testing showed coverage of about 1,268 square feet per charge on hard floors. If the battery runs low mid-clean, the robot returns to charge and picks up where it left off.

The Dock

The multifunction dock measures a substantial 13.4 x 19.2 x 20.5 inches, so plan your placement accordingly. But it earns that footprint: 2.7-liter dustbags last roughly seven weeks, 4.25-liter water tanks handle over 3,500 square feet of mopping, and hot-air drying keeps mop pads from getting musty. Noise levels hit 78.2 dB during self-emptying—loud, but noticeably quieter than older Roborock docks.

Where It Falls Short

Obstacle Avoidance: The Achilles Heel

Here’s where things get disappointing. The Qrevo S uses structured light alone for obstacle detection—no camera assist like the MaxV or Master. Both RTINGS and Vacuum Wars rated its obstacle avoidance as the worst in the Qrevo lineup.

What does that mean in practice? Cables get tangled. Socks get sucked up. Shoes get bumped. Pet bowls scatter. Toys become obstacles the robot crashes into rather than navigates around. If a pet accident happens while you’re out? The robot might run straight through it.

Roborock claims the system recognizes 62 object types. Testing suggests it recognizes far fewer reliably.

The Dark Surface Problem

Cliff sensors prevent robots from tumbling down stairs. But on the Qrevo S, these sensors frequently mistake dark rugs, black tiles, and anti-fatigue mats for deadly drops. The robot stops, confused, and refuses to cross. Some owners cover the sensors with tape; others set up virtual barriers around problem areas. Neither solution feels like something you should need with a $799 robot.

Pet Hair on Carpet

The Qrevo S handles pet hair beautifully on hard floors. On carpet? Testing showed 10-20% of pet hair remained embedded after cleaning. The anti-tangle rubber brush works great at preventing hair from wrapping around the roller, but it doesn’t dig deep enough into carpet fibers to lift what’s already trapped there.

Fine dust and allergens pose another problem. RTINGS found roughly 30% of fine particles escape through the exhaust, bypassing what Roborock calls a HEPA filter.

No Hot Water Mopping

The dock washes mop pads with room-temperature water only. The MaxV and Master both use 140°F water, which does a better job at sanitizing. If you’re counting on the Qrevo S to deep-clean floors in a home with kids or pets, the cold water limitation matters.

The App Experience

Roborock’s app earns above-average ratings on both iOS and Android. Setup requires WiFi (2.4 GHz only), and some smart features won’t work offline. But once connected, you get:

• Multi-level mapping with room-by-room customization
• Virtual barriers and no-go/no-mop zones
• SmartPlan AI that optimizes cleaning based on room type
• Five suction levels and 30 water flow settings
• Adjustable mop wash frequency and self-empty scheduling
• Maintenance tracking for filters, brushes, and pads
• Alexa and Google Home integration

What you don’t get: video monitoring, pet detection photos, or the “Hello Rocky” voice assistant found on pricier models.

Maintenance Costs

Annual upkeep runs roughly $100-150 with official parts:

Part	Replacement Interval	Cost
HEPA Filter	6-12 months	$15-25
Main Brush	6-12 months	$20-30
Side Brush (2-pack)	3-6 months	$15-25
Mop Pads (pair)	1-3 months	$20-30
Dust Bags (3-pack)	~2 months each	$10-15

Third-party alternatives cost less but vary in quality. Most owners rinse filters weekly and rotate between multiple sets to ensure proper drying.

Warranty Warning

Roborock offers a standard one-year warranty, but multiple Trustpilot reviews report aggressive claim denials and multi-week response times. Buying an extended warranty through Amazon or your retailer is strongly recommended.

How It Compares

vs. Qrevo MaxV ($999): Same suction power, but the MaxV adds camera-based obstacle avoidance, hot water mopping, a flexi-arm side mop, video calling, and pet detection. Worth the extra $200 if you have pets or a cluttered home.

vs. Qrevo Master ($1,199): 43% more suction (10,000 Pa), dual brushes that handle pet hair better, AI camera navigation, and hot water cleaning. The premium choice for carpet-heavy or pet-heavy households.

vs. Ecovacs Deebot T30S ($799): The T30S offers higher suction (11,000 Pa) and longer battery life (290 minutes), but the Qrevo S has more reliable navigation software and arguably better mopping performance.

Who Should Buy This

The Qrevo S makes sense for homes with mostly hard floors, minimal clutter, and no dark rugs. It’s a solid pick for multi-story homes where the four-map capability helps, and for budget-conscious buyers who want dock automation without paying $1,000+.

Skip it if you have shedding pets, frequently dropped items on floors, high-pile carpet, or dark floor surfaces. The obstacle avoidance limitations make it a frustrating choice for households that can’t guarantee a clear path.
