Roborock S5 Max Review: Set-and-Forget Robot Vacuum Reviewed

The Roborock S5 Max is a robot vacuum designed for daily maintenance cleaning on hard floors and low-pile carpet.

Verdict: A reliable daily robot vacuum with excellent lidar navigation and quiet operation. The mopping is too light for serious cleaning, but the vacuum side delivers solid results for daily maintenance. 8.5/10.

Best for: Busy households with mostly hard floors and low-pile carpet who want hands-off daily vacuuming with an occasional light wipe.

Skip if: You need genuine scrubbing mopping, have dark-patterned rugs that confuse cliff sensors, or run a large pet-heavy home that would overflow the small dustbin daily.

The S5 Max is a mid-range robot vacuum designed for daily maintenance cleaning on hard floors and low-pile carpet.

At a glance

What we liked

Precise Lidar Mapping

The S5 Max uses lidar navigation to build a floor plan on its first run, and it updates that map in real time as furniture shifts. It reliably avoids obstacles like chair legs and stays within designated rooms. Users can label each room in the app and send the robot to a specific spot with a single tap. This level of precision sets it apart from older randomized-bounce robots and means clean floors from day one, not after a week of "learning."

Quiet Enough for Daily Life

At 2000Pa on hard floors, the S5 Max runs at a volume where conversations or watching TV in the same room are possible. Even on carpet boost mode, the noise increase is noticeable but not jarring. For busy households, this quiet operation encourages frequent use, including during times when pets or children are resting.

Custom No-Go and No-Mop Zones

Solid Suction with Carpet Boost

On hard floors, 2000Pa suction is sufficient for everyday crumbs and dust. The robot automatically increases suction when it detects carpet, improving pickup on low-pile rugs and embedded pet hair on medium-pile carpet. Although the brush requires cleaning after use, the suction performance is impressive given the quiet operation.

Where it falls short

Mopping Is a Damp Wipe at Best

The S5 Max drags a microfiber pad across the floor with a small water tank that drips moisture onto the pad. It does not scrub, so sticky spots from juice or dried food do not come up. Floor cleaner cannot be used in the tank, only water. For homes needing actual mopping on tile or vinyl, this is a limitation. The mop function is best suited for light maintenance between deeper hand-mopping sessions.

Cliff Sensors Struggle with Dark or Patterned Rugs

The cliff sensors that prevent falls can mistake dark rugs for drop-offs. Dark-patterned rugs may cause the robot to reverse sharply, circle, or stop. Some owners address this by covering sensors with tape or setting no-go zones, but it remains an annoying limitation for a robot that otherwise navigates well.

Small Dustbin Means Frequent Trips

Real-world performance

Daily Maintenance with Two Cats

Owner feedback indicates the S5 Max covers around 1200 square feet of mixed hard floors and low-pile carpet in about 60 minutes, using approximately 60 percent of its battery. It provides good visible pickup on hard floors and lifts embedded fur on carpet with its boost mode. The dustbin requires emptying after each run. The lidar map updates dynamically when furniture is moved, allowing the robot to adjust its path accordingly.

Hard Floors and Area Rugs

The S5 Max transitions smoothly between tile, hardwood, and low-pile rugs without getting stuck. The side brush manages most rug edges without catching. The no-mop zone feature effectively keeps rugs dry by stopping the mop function before reaching them and resuming afterward. This smooth transition is uncommon even in more expensive robots.

Mopping Light Foot Traffic

The water tank and mop pad leave floors feeling slightly cleaner under bare feet after a mop-only pass on tile. However, dried spots from spills do not come up. The mop function is suitable for daily dust mopping between deeper cleans but not for sticky messes.

How it compares to alternatives

Who should buy it

It is less suitable for homes with thick or dark-patterned rugs, large pet populations, or those expecting effective mopping. Robots with self-emptying docks, improved cliff sensors, or active scrubbing may be better in those cases.

FAQ

How much area can it clean on a single charge?

A fully charged S5 Max can clean about 2000 square feet of mixed flooring in around 90 minutes, with battery to spare. If the battery runs low mid-cycle, it automatically docks, recharges to 80 percent, and resumes cleaning where it left off.

Does long hair get tangled in the brush?

Yes, the main brush tends to wrap long human hair more than some rubber brush designs, so weekly cleaning is recommended. The included cutting tool facilitates this maintenance. For users prioritizing tangle-free operation, alternative vacuums are available.

Can it climb thick rugs or high-pile carpet?

The S5 Max handles low to medium-pile rugs easily, but high-pile or shag rugs may catch the side brush and stop the robot. Setting no-go zones for these areas is a common solution.

Should I use floor cleaner in the water tank?

No, the water tank is designed for water only. Adding floor cleaner can clog the system and cause damage, according to manufacturer guidelines.

Can I set no-go zones for specific rooms?

Yes. The app allows drawing rectangular no-go zones and invisible walls on the map. Separate no-mop zones can also be set, which disable mopping but allow vacuuming in those areas. This functionality is reliable.

Is the Roborock S5 Max compatible with Google Home?

Yes. The S5 Max works with both Alexa and Google Assistant. Users can start, stop, or send the robot to specific rooms by voice commands. Voice assistant integration is consistent, though room names must match those set in the app.
