Roborock S8+ Review: Is the Auto-Empty Dock Worth It?

The Roborock S8+ is the smart middle option in the S8 family — the same vacuuming-beast robot as the base S8, paired with an auto-empty dock that hides the dirty work for weeks. At $289.99 (down from a $999.99 launch), it nails the one dock upgrade most people actually want without dragging you into omni-dock prices. The catch: it still does not wash or dry its own mop, so heavy moppers should look elsewhere.

30-Second Summary

- Best for: Hard-floor and pet homes that want strong suction plus weeks of hands-off emptying

- Skip if: You mop daily (no mop washing) or have wall-to-wall carpet with pets

- Our score: 8.2/10

- Price: $289.99 (71% off — ↓ dropped hard from a $999.99 launch)

- One-line verdict: A vacuuming powerhouse with the auto-empty convenience that matters most.

The S8+ sits in the middle of a confusing lineup. The base S8 ships with a plain charging dock. The S8+ adds the auto-empty station you see in this review. The S8 Pro Ultra swaps in a full omni dock that also washes and dries the mop. If you mostly vacuum and only mop now and then, the S8+ is the sweet spot. We break down that choice in detail in our Roborock S8 vs S8+ comparison.

Key Specs

Multi-Source Score

Scores collected from publicly available reviews as of June 2026. The S8+ uses the same robot as the base S8, so cleaning and navigation results carry over directly.

Price Watch

💡 Buy timing tip: The S8+ launched near $999.99 and now hovers around $289.99. Prime Day and Black Friday have pushed it lower still — if you can wait for a sale event, you will often catch it near its historical low of $289.99.

Design & Build

The robot itself is understated and well-built. It is a low-profile black puck with a retractable PreciSense LiDAR turret on top, and at roughly 3.8 inches tall it slides under most sofas and kick-toes. The auto-empty dock is the visible change versus the base S8 — a compact tower with a handle and a 2.5L bag tucked inside.

What you do not get here is a sprawling omni station. There are no clean- and dirty-water tanks, no mop-washing tray, no drying fan. The dock does exactly one job: it sucks the robot's dustbin empty and stores the debris. That focus keeps the footprint small — this is a dock that fits in a hallway corner, not one that demands a utility closet.

Build quality is classic Roborock. The bumper, the rubber rollers, and the dock latch all feel solid, and owners routinely report years of trouble-free use. One Reddit owner running two base-model S8s summed up the durability bluntly: "Both of them are base model... they just keep performing very, very well!"

Navigation & Mapping

Navigation is a genuine strength. The PreciSense LiDAR system builds a map fast and drives in tidy, efficient lines rather than the bumbling random patterns of cheaper robots. On the S8 platform, Vacuum Wars clocked a full floor-plan map in about four minutes — faster than any flagship they had tested at the time — and called it the most efficient navigator in its class.

Obstacle avoidance is handled by Reactive 3D, which uses structured light and infrared instead of an RGB camera. For privacy-minded buyers that is a plus: there is no front-facing camera streaming your living room. In standardized testing the S8 family scored 9 out of 12 on obstacle avoidance — top-tier, dodging shoes, cables, and cords on hard floors.

There is one honest caveat. The structured-light system gets confused on carpet — the fibers scatter the light, and the robot will sometimes bump objects on a rug that it would have neatly avoided on tile or wood. If your home is mostly hard floors, you will rarely notice. If it is mostly carpet, expect the occasional nudge.

Cleaning Performance

This is where the S8+ earns its keep. The 6,000Pa HyperForce motor is roughly three times the suction of Roborock's budget machines, and it shows. In independent testing the S8 platform pulled 97.9% of debris overall, with hardwood at 99.5%, low-pile carpet at 97.2%, and high-pile carpet at 96.9%. Those are flagship-grade pickup numbers from a robot that now costs less than $289.99.

The DuoRoller brush system — two rubber rollers with zero bristles — is the unsung hero for pet owners. Long hair and pet hair slide off the rubber instead of wrapping into a knot, so the weekly maintenance is genuinely quick. Reddit owners are blunt about the raw vacuuming: "All S8s are vacuuming beasts. Almost nothing available for any price right now can beat them." Another, comparing it to a far pricier robot, wrote simply, "I love my cheap S8s!"

On a kitchen floor after cooking — flour dust, cereal, a spilled bag of rice — the S8+ clears it in a single confident pass. On low-pile rugs it automatically ramps suction and digs in. The one place it shows a limit is deep, plush carpet with embedded pet hair, where, like most robots, it leaves a little behind that a deep-clean upright would catch.

A long-term word of caution from owners: running max suction constantly on delicate carpet can, over months, tug at and fray loose fibers. Drop to a medium suction setting on rugs you care about and you avoid the problem entirely.

Mopping Performance

Mopping is the weakest part of the package, and you should buy with that expectation. The VibraRise 2.0 system vibrates a flat pad up to 3,000 times per minute, and it does fine on light, fresh spills — fingerprints, dust film, a splash of juice wiped soon after. It auto-lifts the pad about 6mm when it detects carpet, so it will not drag a wet pad across your rug.

But this is scrubbing-by-vibration, not the pressurized spinning or roller mops on pricier machines, and dried-on messes defeat it. One Reddit owner put it plainly: the mop "just doesn't do well with only vibrating," and another noted it "dragged on the carpets" in edge cases. Crucially, the S8+ dock does not wash or dry the pad — you rinse it by hand after each run and hang it to dry, or it develops a musty smell.

If serious mopping is a priority, this is the line where you should consider stepping up to the Roborock S8 Pro Ultra, whose omni dock washes and dries the pad for you.

The Auto-Empty Dock

The dock is the whole reason to buy the S8+ over the base S8. After every clean, the robot reverses into the station and the dock vacuums its 300ml bin into a 2.5L sealed bag. Roborock rates the bag for up to seven weeks before it needs changing, and SGS-tested filtration captures pollen and pet allergens on the way through. For most homes that means you handle dust roughly once a month or less, instead of after every single run.

There are two honest trade-offs. First, the onboard bin is small at 300ml, so the dock empties often — that is by design, but it is not a "set it and forget it" 1L bin. Second, the emptying cycle is loud: independent testing measured it at 74.3 dBA, noticeably louder than the robot at full suction. It only lasts a few seconds, but it is the kind of sound that will make you glad you scheduled cleanings for when you are out of the house.

Battery & Noise

The 5,200mAh battery delivers around 180 minutes in standard mode, enough to cover roughly 2,000 square feet on a single charge. If it runs low mid-job, it returns to the dock, tops up, and resumes where it left off — so multi-room homes are handled without babysitting.

At cleaning the robot is quiet enough at about 67 dB to run while you are in the next room. The only real noise event is that auto-empty cycle described above. Schedule it for when you are out and noise is a non-issue.

App & Smart Features

The Roborock app is the best in the business, and it is a real reason to buy. Mapping is fast and accurate, and you get the full toolkit: no-go zones, no-mop zones, room-by-room cleaning, custom suction and water levels per room, and multi-floor maps for homes with stairs. Starting a single-room clean takes a couple of taps. It works with Alexa, Google Assistant, and Siri Shortcuts, so a voice command can kick off a quick tidy.

After living with cheaper robots whose apps feel like afterthoughts, the polish here stands out — and it is a small thing you interact with every day, which is exactly why it matters.

Maintenance & Running Costs

The auto-empty dock is the headline maintenance win: the 2.5L bag goes weeks between changes, and replacement bags are cheap. The DuoRoller's rubber design means hair rarely tangles, so clearing the brush is a quick weekly job rather than a scissors-and-patience ordeal. As one owner described the weekly upkeep, "It will take me a few minutes and it is very easy to do."

The ongoing chore the S8+ does not solve is the mop pad. Because the dock does not wash it, you hand-rinse and dry the pad yourself after mopping runs. Budget for occasional replacement pads, filters, and dust bags — none of it expensive, but the mop side stays manual.

Who Should Buy This

Buy the S8+ if you have mostly hard floors and want serious suction without babysitting the dustbin. It is a standout for pet owners thanks to the tangle-resistant DuoRoller and strong pickup, and the auto-empty dock means you deal with dust about once a month. At $289.99, it is one of the best pure-vacuuming values on the market. Check on Amazon

Skip it if mopping is central to your routine — the hand-washed pad and vibration-only scrubbing will frustrate you, and the S8 Pro Ultra or a dedicated roller-mop robot is a better fit. Also skip it if your home is wall-to-wall plush carpet with pets, where any robot leaves embedded hair behind.
