Roborock S8+ Review: Hands-Free Vacuum and Mop

If you want floors cleaned without having to think about it, the Roborock S8+ makes a strong case. It pairs a 6000Pa vacuum with a vibrating mop pad and a dock that empties the dustbin for you, meaning weeks can pass between hands-on maintenance.

Owners consistently point to two standouts: mapping that’s quick to set up and edit, and dual rubber brushes that cut down on hair tangles in pet households. The trade-off is a mop system that handles daily dust and light spills better than dried-on messes.

Runtime lands around 180 minutes, while obstacle avoidance uses 3D structured light with infrared imaging for dark rooms. App control covers no-go zones, schedules, suction levels, and water flow, and Alexa and Google Home voice commands work as well.

Bottom Line

The S8+ suits homes with pets, mixed flooring, and enough furniture to make manual vacuuming tedious. If hands-free upkeep between deep cleans is the goal, check current availability and pricing on Amazon.

Roborock S8+ Robot Vacuum Overview

Two systems define this machine: the DuoRoller brush assembly for vacuuming and the VibraRise mop that lifts when carpet is detected. The RockDock Plus adds self-emptying into a 2.5L bag rated for roughly seven weeks of debris.

Specification	Detail
Suction	6000Pa HyperForce
Mop	Sonic vibration, up to 3,000 scrubs/min, 6N pressure
Battery life	Up to 180 minutes
Dust bag	2.5L, up to 7 weeks
Noise level	68.5 dB
Obstacle avoidance	3D structured light + infrared
Connectivity	2.4GHz Wi-Fi, app, Alexa, Google Home
Dock dimensions	15″ x 19.25″ x 14.53″

Mapping is a highlight. The 3D map lets you place furniture, split or merge rooms, and send the robot to a specific area by voice or through the app.

Customer Review Snapshot

Feedback skews positive, with a solid average across several hundred ratings. Buyers upgrading from older Eufy and Roomba units describe noticeably better suction and cleaner hard floors.

Pet owners with dogs and busy kitchens full of chair and table legs report that navigation handles the clutter well. Hair rarely wraps around the rollers, too.

Spanish-language reviewers in smaller apartments note easy setup, quiet operation on marble and rugs, and reliable scheduled runs.

Criticism clusters around reliability for a minority of buyers. Complaints include the auto mop lift failing to engage, occasional self-empty errors, and dust escaping during dock cycles. A few users needed several weeks to learn the app’s deeper settings.

If you are weighing the docked version against the standard model, our roborock S8 robot vacuum review covers the same cleaning hardware without the auto-empty base.

6000Pa Suction and DuoRoller Brush

Debris pickup is the strongest part of this machine. The twin rubber rollers work against each other, grabbing embedded dirt on low-pile carpet while sweeping crumbs and pet hair off hardwood and tile.

Rubber matters here because long hair slides toward the end caps instead of spinning into a bristle bar. Owners with shedding dogs report far less cutting and untangling than with older brush-roll designs.

Ultrasonic carpet detection bumps suction automatically when the robot crosses onto a rug. At the highest setting, noise measures 68.5 dB, loud enough to notice in the same room but reasonable for the airflow it produces.

Edges and corners still need occasional manual attention, which is standard for round robots.

VibraRise Sonic Mopping

Sonic vibration drives the pad up to 3,000 times per minute under 6N of downward pressure. It handles dried coffee rings and light kitchen spills better than a passive drag pad, while water flow adjusts in the app across several levels.

The lift function raises the mop when carpet is detected, so you can run a single vacuum-and-mop pass across mixed flooring. A small number of owners report that the lift fails to trigger reliably.

Refills are manual. There is no clean or dirty water tank in the dock, so you fill the onboard reservoir and rinse the pad yourself after runs. Heavy mopping households may prefer a dock that washes pads, like the setup in our roborock Qrevo Plus robot vacuum and mop review.

RockDock Plus Self-Emptying System

Emptying happens automatically at the end of each run, pulling debris into a 2.5L sealed bag. With average household use, that stretches to around seven weeks before a bag change.

The dock stands about 14.5 inches tall and 19.25 inches wide, so plan for a clear stretch of wall with open space in front. Evacuation is brief but loud, which is worth considering if you schedule cleanings while people are sleeping.

Bags are a recurring cost. Some owners have run into occasional evacuation errors or dust puffing out during the cycle, usually because of a full bag or a poorly seated dustbin.

Pros and Cons

Pros

• Strong 6000Pa suction pulls debris from low-pile carpet and hard floors
• Dual rubber rollers dramatically reduce hair tangling
• Fast, accurate 3D mapping with easy room editing and zone controls
• Sonic mop with real downward pressure, not a passive drag pad
• Seven weeks of hands-free dust collection in the dock
• Reliable obstacle avoidance in dark rooms thanks to infrared imaging
• Works with Alexa and Google Home

Cons

• No self-washing mop pad; rinsing and refilling stay manual
• Mop lift does not engage consistently for every owner
• Dock is bulky and requires dedicated floor space
• Auto-empty cycle is loud and occasionally reports errors
• Ongoing cost of replacement dust bags
• App has a learning curve before advanced settings make sense

Frequently Asked Questions

Is the Roborock S8+ worth buying for homes with pets?

Yes, pet owners are among the most satisfied buyers of this model. The dual rubber rollers resist hair wrap far better than bristle brushes, and the sealed dust bag keeps allergens contained between changes. Long-haired breeds still call for an occasional check of the roller end caps.

Does the Roborock S8+ vacuum and mop at the same time?

It does both in a single pass, with the mop pad attached while the vacuum runs. Ultrasonic carpet detection lifts the pad when the robot crosses onto a rug, so carpet stays dry during a combined run. You can also disable mopping entirely in the app for vacuum-only cleaning.

How often do you need to empty the Roborock S8+ dock?

The 2.5L bag holds up to about seven weeks of debris in a typical home. Households with pets or high traffic will hit that mark sooner, closer to four or five weeks. The app sends an alert when the bag needs replacing.

Does the Roborock S8+ work well on carpets and hard floors?

It performs on both, with suction rising automatically when carpet is detected. Hardwood, tile, and marble see the cleanest results, while low-pile rugs and area carpets are handled well. Deep or high-pile carpet is beyond what any robot vacuum fully cleans.

Can the Roborock S8+ avoid cords and other objects on the floor?

Yes, 3D structured light paired with infrared imaging can identify cables, shoes, and pet bowls in both lit and dark rooms. Detection is generally solid for reasonably sized objects, although thin cords and small items like socks still get caught occasionally.

Clearing the floor before a run gives the best results. For more comparisons, see our robot vacuum reviews.
