Roborock S8 leads in power and smarts; S7 gives top value and reliability.
Imagine hitting “Start” on your phone, leaving for work, and returning to spotless floors. That’s the promise behind the Roborock S7 vs S8 debate. Both clean well, map fast, and handle daily mess with ease. Yet they aim at different buyers. If you want stronger suction and better obstacle avoidance, the S8 feels like the future. If you want a proven workhorse with excellent mopping and a better price, the S7 is still a star. I’ve tested and advised on these models for years, and I’ll break down what truly matters so you can buy with confidence—without overpaying for features you won’t use.

Roborock Mop Cloth for S8/S8+/S7 MaxV (2-Pack)
This 2-pack Roborock mop cloth is made for the S8, S8+, and S7 MaxV models. It snaps on fast and provides even water distribution, so floors get a consistent scrub. The fabric holds up to repeated washes, which helps keep your mopping performance steady over months of use. If you run your robot several times a week, swapping in a fresh pad keeps grime from spreading and floors looking clean.
In the Roborock S7 vs S8 conversation, routine maintenance is a big deal. The S8 has stronger suction, but both benefit when the mop cloth grips fine dust and sticky spots. I like to keep at least two clean pads ready to go—one on the robot and a spare drying after a wash. It makes a big difference for busy homes with kids, pets, or high-traffic kitchens.
Pros:
- Designed to fit S8, S8+, and S7 MaxV precisely
- Even water spread for a stable mopping finish
- Fabric stands up to frequent washing
- Quick to install and remove for cleaning
- Boosts pickup of fine dust on hard floors
- Helps reduce streaks on sealed wood and tile
- Affordable way to refresh mopping performance
- Great for homes with pets that track in dirt
- Works well with moderate water settings
- Pairs nicely with daily or every-other-day runs
- Keeps the S8’s VibraRise mopping effective longer
- Soft texture is gentle on delicate finishes
Cons:
- Not compatible with the standard S7 (only S7 MaxV listed)
- Needs regular washing to prevent odor buildup
- Heavy messes may still need pre-spray or manual spot clean
My Recommendation
If you own a Roborock S8, S8+, or S7 MaxV, this 2-pack is a smart buy. Pads are consumables, like vacuum bags, and swapping them on time maintains high performance. When I test Roborock S7 vs S8 mopping results, a fresh cloth pad closes the gap on fine dust and tough, sticky spills. The S8 does better with power and obstacle handling, but mopping finish relies on clean, intact fabric. This set gives you the consistency you need for daily shine without spending a lot.
Use it if you run the robot three or more times a week, or if your floors get frequent kitchen spills. I suggest keeping a rotation: one pad in use, one drying. That rhythm keeps the S8’s sonic mopping at its best and helps the S7 MaxV match up well in real homes. If you’re comparing Roborock S7 vs S8 for hard floors like tile, engineered wood, and vinyl plank, a clean mop cloth often matters as much as model choice. It’s a small upgrade with big impact on the look of your floors.
| Best for | Why |
|---|---|
| Daily mopping upkeep | Fresh pads keep streaks down and shine up |
| Homes with kids or pets | Grabs fine dust and sticky mess without harsh scrubbing |
| S8/S8+ and S7 MaxV owners | Perfect fit ensures even water flow and steady results |
Side Brushes for S-Series & Q-Series (2-Pack)
This 2-pack of black side brushes fits a wide range of Roborock models, including S8 Pro Ultra, S7 Max Ultra, Q Revo, Q-series, and many S and E series units. If you’ve compared Roborock S7 vs S8 and noticed edge pickup differences, fresh side brushes narrow that gap fast. These brushes sweep debris from corners and baseboards into the main rollers. That action is key for clean edges—an area many robots struggle with.
Side brushes wear out over time and get bent by chair legs and low cabinets. I swap mine every few months to keep pickup strong, especially on pet hair that clings to edges. In my long-term testing, timely brush replacement helps the S7 keep up with the S8 in visible floor cleanliness. For most homes, this low-cost maintenance step gives a bigger improvement than many app tweaks.
Pros:
- Wide compatibility across S, Q, and E series
- Improves edge and corner pickup quickly
- Easy to snap in with no tools
- Helps gather hair for the main roller
- Durable material resists fraying
- Keeps airflow paths clear near baseboards
- Great upgrade before big cleanups or guests
- Budget-friendly way to refresh an older unit
- Pairs well with increased suction modes
- Supports better mapping accuracy near walls
- Helps S7 look closer to S8 on visible dirt
- Spare set reduces downtime when cleaning
Cons:
- Not every color matches every robot body
- Worn brushes can scatter light debris if not replaced
- May catch on very low or loose rugs
My Recommendation
If you are focused on real-world results in the Roborock S7 vs S8 debate, update the side brushes before judging. Edge and corner cleaning make or break the look of a room. Fresh brushes change that look in a single run. The S8 line uses stronger suction and dual rollers to pull more from edges, but the S7 gains ground with clean, crisp side brushes that sweep debris inward. When I review user homes, I can tell right away who replaces side brushes on time and who does not—the edges give it away.
I suggest marking your calendar every 3–4 months to check brush condition. Bent bristles or heavy wear mean it’s time to swap. Do a quick clean of hair on the axle when you install the replacements. Then run a full pass on “Balanced” or “Turbo” mode. For a Roborock S7 vs S8 side-by-side, this small maintenance step helps the S7 keep pace in day-to-day dust pickup. It also helps the S8 shine on hard floors and carpet transitions, where fresh side brushes cut down on missed crumbs near thresholds.
| Best for | Why |
|---|---|
| Edge and corner cleanup | Brushes funnel debris to the main roller path |
| Budget performance boost | Low-cost swap improves visible results fast |
| Mixed floor homes | Helps grab crumbs at transitions and along baseboards |
