Where the Roborock Qrevo S5V Wins

1. Higher Suction for Deep Cleaning

The Qrevo S5V delivers 12,000 Pa of suction—2,000 Pa more than the QV 35S. For pet owners, that extra power makes a noticeable difference when pulling embedded hair from carpets, area rugs, and upholstery edges. It also helps with fine dust on hard floors, especially in high-traffic zones.

2. Intelligent Obstacle Avoidance

The S5V includes intelligent obstacle avoidance, which means it can detect and steer around items like shoes, cables, and pet bowls without bumping into them. This is a real time-saver if your floors tend to collect clutter throughout the day. The QV 35S does not list this feature in its verified specs, so the S5V has a clear edge for homes where you want the robot to navigate more autonomously.

3. Auto-Empty and Auto-Refill Base

The S5V’s base station handles auto-vacating and auto-refilling. That means the robot empties its dustbin into the base after each cleaning and refills its water tank for mopping—no manual intervention required for multiple cycles. This is ideal if you want a “set it and forget it” experience, especially during busy weeks.

Where the Roborock QV 35S Wins

1. Better Value at a Lower Price

At roughly $497.08, the QV 35S undercuts the S5V by about $55. For shoppers on a tighter budget, that savings can go toward replacement parts or accessories. Despite the lower price, the QV 35S still offers strong suction and a full mopping system.

2. Higher User Rating

The QV 35S holds a 4.5 out of 5 rating from 360 reviews, slightly edging out the S5V’s 4.4 from 600 reviews. While ratings aren’t everything, a higher score from a solid sample size suggests consistent performance and customer satisfaction.

3. Multifunctional Base with Cleaning and Drying

The QV 35S comes with a multifunctional base that not only cleans the mop pads but also dries them. This is a key advantage for households that mop frequently—damp mop pads can develop odors or mildew if left wet. The S5V’s base focuses on auto-empty and refill, but doesn’t explicitly mention mop drying in its verified features.

4. Automatic Mop Lifting (10 mm)

Both models have liftable mops, but the QV 35S specifies 10 mm automatic elevation. This allows the robot to lift its mop pads when transitioning from hard floors to carpet, keeping carpets dry. The S5V also has a liftable double mop, but the exact lift height isn’t confirmed in its fact sheet.

Verdict by Use Case

Best for Pet Owners with Heavy Carpeting: Roborock Qrevo S5V

If your home has significant carpeted areas and you deal with heavy pet shedding, the Qrevo S5V is the stronger choice. Its 12,000 Pa suction pulls deeply embedded hair from fibers, and the intelligent obstacle avoidance helps it navigate around pet toys and bowls without getting stuck. The auto-empty base also means you won’t have to empty the dustbin after every run—a real convenience when pet hair accumulates quickly.

Best for Mixed Flooring and Frequent Mopping: Roborock QV 35S

For homes with mostly hard floors and occasional carpet, the QV 35S offers excellent value. Its 10 mm auto-lift mop keeps carpets dry, and the multifunctional base that cleans and dries mop pads is a big plus if you mop daily or have pets that track in mud. The slightly lower suction (10,000 Pa) is still plenty for hard floors and low-pile rugs.

Best for Budget-Conscious Shoppers: Roborock QV 35S

If you want strong performance without spending over $500, the QV 35S delivers. It’s about $55 cheaper than the S5V and has a higher user rating. You sacrifice some suction power and obstacle avoidance, but you gain mop drying and a proven track record.

Best for Fully Automated Cleaning: Roborock Qrevo S5V

If your goal is to minimize hands-on maintenance, the S5V’s auto-empty and auto-refill base is hard to beat. You can go multiple cleaning cycles without touching the robot or the base. The trade-off is that the base doesn’t explicitly dry the mop pads, so you may want to remove them manually after mopping sessions.

Final Thoughts

Both the Roborock Qrevo S5V and QV 35S are strong contenders for pet hair and mopping. The S5V leads on raw suction and obstacle avoidance, while the QV 35S offers better value and a more complete mopping base. Your decision should come down to your floor type, how much automation you want, and whether you’re willing to pay extra for higher suction.

For most pet owners with mixed flooring, the QV 35S is the smarter buy—it covers the essentials well at a lower price. But if you have thick carpets or want the most hands-off experience possible, the Qrevo S5V justifies its premium.
