Roborock S8 MaxV Ultra Review: Best for Pet Hair

If you share your home with pets, you already know the struggle: fur everywhere, all the time. The Roborock S8 MaxV Ultra is purpose-built to handle exactly that. With dual rubber roller brushes that resist hair tangles, 6,000Pa of suction, and one of the smartest obstacle avoidance systems on the market, it has earned our recommendation as the best robot vacuum for pet hair in 2026. Here is what three months of testing revealed.

Quick Summary

Why Pet Owners Need a Different Robot Vacuum

Standard robot vacuums use bristle brushes that wrap and tangle with pet hair within days. This reduces suction, requires frequent manual cleaning of the brush, and can even burn out the motor over time. The S8 MaxV Ultra solves this with dual rubber roller brushes that are almost completely tangle-free. After three months of daily cleaning in a home with two long-haired cats, the brushes required manual detangling exactly once.

The other critical feature for pet owners is obstacle avoidance. Pets leave toys, food bowls, and occasionally unpleasant surprises on the floor. You need a robot that can see them and steer clear.

Design and Build

The S8 MaxV Ultra is a premium-feeling machine. At 14.1 inches in diameter and 3.9 inches tall, it is slightly larger than the eufy X10 Pro Omni but still navigates under most furniture without trouble. The top-mounted LiDAR turret is the tallest point.

The RockDock Ultra Base Station

The base station is a full-service maintenance hub. It empties the dustbin, washes and dries the mop pad, and refills the clean water tank. The dust bag holds approximately 7 weeks of debris (in our pet-heavy testing environment, closer to 4 weeks). A UV sterilization module in the base station kills bacteria in the dustbin after each empty cycle, which is a nice touch for homes with pets.

The base station is large. It requires about 18 inches of wall clearance and 24 inches of front clearance for the robot to dock. Plan your placement carefully.

Pet Hair Cleaning Performance

This is the core of our evaluation, and the S8 MaxV Ultra delivers outstanding results.

Hard Floor Pet Hair

We distribute a measured amount of long pet hair (collected from real cats) across a 100 square foot hardwood test area. The S8 MaxV Ultra picked up 98.7% in a single pass, with virtually no hair left behind along edges or in corners. The dual rubber rollers grab hair from the floor and channel it into the dustbin efficiently.

Carpet Pet Hair

On medium-pile carpet, the S8 MaxV Ultra excels. It pulled up 96% of surface pet hair and 86% of embedded hair in a single pass. These are the highest carpet pet hair scores we have recorded. The combination of dual rubber rollers and 6,000Pa suction creates a deep-cleaning effect that bristle brushes simply cannot match.

For comparison, the eufy X10 Pro Omni scored 91% on surface pet hair and 81% on embedded hair on the same carpet. The Roborock's advantage is clear and consistent.

Tangle Resistance

After 90 days of daily cleaning in a two-cat household, the dual rubber rollers accumulated minimal hair wrapping. We checked the brushes weekly and only needed to remove a small tuft of wound hair once, during week 6. By contrast, our bristle-brush test units required cleaning every 3 to 5 days in the same environment.

Obstacle Avoidance

The S8 MaxV Ultra uses a triple-sensor system: LiDAR for room mapping, an RGB camera for object identification, and structured light (similar to what is used in facial recognition) for precise distance measurement in low light.

Test Results

In our standardized obstacle course, the S8 MaxV Ultra avoided 97% of objects, the highest score of any robot vacuum we have tested. It correctly identified and routed around shoes, pet toys, cables, socks, and pet food bowls. It even detected and avoided a simulated pet accident (a controlled test, for science) with 100% reliability.

The Roborock app sends you a photo notification when the robot detects an obstacle it cannot identify, which gives pet owners peace of mind that the robot is not going to spread anything unpleasant across the house.

Navigation and Mapping

LiDAR navigation is fast and accurate. The initial map of our 1,400 square foot test apartment completed in 16 minutes. The Roborock app provides one of the best mapping experiences in the industry, including:

• 3D map visualization with furniture placement
• Room labeling with custom names and icons
• Multi-floor support (up to 4 maps)
• Detailed cleaning routes visible in real-time
• Furniture detection that auto-labels items like sofas and tables

The app is more feature-rich than what eufy and most other brands offer, though it can feel cluttered for users who just want basic scheduling.

Mopping Performance

The S8 MaxV Ultra uses a sonic vibration mop that scrubs the floor up to 4,000 times per minute. In our dried stain test, it removed 91% of coffee stains in two passes. This is slightly below the eufy X10 Pro Omni's rotating mop (95%), but still very good.

The mop lifts 5mm when carpet is detected. This is lower than the eufy's 12mm lift, and it means thick carpets may get slightly dampened. Roborock addresses this by allowing you to set carpet avoidance zones in the app, which is effective but requires manual setup.

Self-Emptying Performance

The auto-empty cycle is thorough. The base station uses strong suction to pull debris from the robot's dustbin into the station's dust bag. In our testing, the robot's dustbin was consistently empty after the cycle. The station's bag lasted 4 weeks in our heavy pet hair environment before needing replacement. Roborock sells replacement bags in packs of 6 for $29.99.

Noise Levels

The S8 MaxV Ultra is not the quietest robot. In balanced mode, it runs at 61 dB. Max suction mode reaches 74 dB. The auto-empty cycle is the loudest part, hitting 80 dB for about 15 seconds. This is louder than the eufy X10 Pro Omni across all modes.

For pet owners, the noise level is worth considering. Some pets are noise-sensitive and may be stressed by the vacuum. We recommend running the first few cleaning sessions while you are home to see how your pets react, and using quiet mode or scheduling runs when pets are in another room.

Pros and Cons

Pros:

• Best-in-class pet hair pickup on both hard floors and carpet
• Dual rubber rollers resist tangling almost completely
• Industry-leading obstacle avoidance (97% accuracy)
• Feature-rich app with 3D mapping and furniture detection
• Effective self-emptying with UV sterilization
• Strong 180-minute battery life

Cons:

• Premium price at $1,099
• Mop lift is only 5mm (competitors offer up to 12mm)
• Louder than average across all cleaning modes
• Large base station requires significant floor space
• Mopping performance is good but not best-in-class
• App can feel overwhelming for basic users

Who Should Buy the Roborock S8 MaxV Ultra?

This is the robot vacuum for households with cats, dogs, or both. The dual rubber roller design is not a gimmick. It fundamentally solves the hair tangle problem that plagues every bristle-brush robot. The obstacle avoidance system provides genuine peace of mind that the robot will handle whatever it encounters on the floor.

If you do not have pets and want the best overall value, the eufy X10 Pro Omni is a better choice at $300 less. But if pet hair is your primary concern, the S8 MaxV Ultra justifies its premium with measurably better results.

The Verdict

The Roborock S8 MaxV Ultra is the most capable pet hair cleaning robot vacuum you can buy in 2026. Its dual rubber rollers, strong suction, and intelligent obstacle avoidance combine to solve the three biggest pain points for pet owners: hair removal, tangle prevention, and mess avoidance. The premium price is real, but so is the premium performance.
