Is it worth it?
The advent of hands-free cleaning solutions has turned what was once a tedious chore into an almost effortless task. Busy pet owners, allergy sufferers, and anyone juggling a hectic household will appreciate a robot that vacuums and mops simultaneously while navigating complex layouts. In this in-depth review of the Tesvor S8max, we break down real-world performance, ease of use, and long-term reliability to help you decide if it’s the right fit for your home.
We tested the S8max over several weeks on hardwood floors, low-pile rugs, and pet-hair-heavy environments. I can already tell you: if you need a robust auto-empty system and powerful suction in a multi-level home, this model delivers. If you’re seeking flawless app stability or 5GHz Wi-Fi support, you might encounter some limitations.

Key Features
360° LiDAR Navigation
The S8max uses a rotating LiDAR sensor to scan rooms at 6 rotations per second, creating highly accurate, millimeter-level floor plans. This real-time mapping allows the robot to build a layered map over multiple sessions. In practice, you can see furniture outlines and door thresholds rendered accurately on your smartphone.
Auto-Empty Base Station
When the dustbin reaches capacity, the base station automatically extracts debris into a sealed bag for up to 70 days of hands-free cleaning. The process takes just over 10 seconds, and the one-way filter design prevents dust from escaping back into the room. For allergy sufferers, this means minimal contact with allergens.
Ultra-High Suction
With four suction modes culminating at 8000 Pa, the S8max excels at lifting embedded pet hair and fine dust. In daily use, the 1600 Pa standard mode balances power and runtime, while the 8000 Pa max setting tackles deep carpet cleaning or heavy debris in a single pass. Battery draw increases in max mode, but short blasts minimize runtime impact.
Multi-Level Mapping
Supporting up to five distinct floor maps, the S8max adapts seamlessly to homes with basements, upper floors, or split-level layouts. Switching between maps takes seconds via the app, so you can schedule separate cleaning routines per floor without manual intervention. This is invaluable for larger estates or multi-story apartments.
Smart Mop System
The magnetic mop attachment includes a 350 mL water reservoir with three adjustable output settings. It lifts automatically off carpets, avoiding soggy fibers, and the even water distribution prevents puddles. I found the medium setting ideal for routine maintenance, while the high flow easily dissolves dried-on spills in the kitchen.
Firsthand Experience
Unboxing the S8max was straightforward: the robot, mop attachment, auto-empty base and accessories arrived snugly packed, accompanied by a clear instruction manual. Within 10 minutes the hardware was assembled and ready. The first full charge took 5 hours, matching Tesvor’s claim, and the LED indicator was intuitive—even for first-time users.
Mapping with the 360° LiDAR scanner surprised me by finishing a two-bedroom, one-living-room home in under 3 minutes, producing an accurate floor plan in the Tuya Smart app. Walls and furniture were correctly identified, and I assigned no-go zones around my cat’s litter area with pixel-level precision.
Over multiple cleaning cycles the S8max handled pet hair on low-pile rugs and hardwood effortlessly. In silent mode (800 Pa) it whirred quietly enough for TV volume at 20%, while the max mode (8000 Pa) visibly lifted embedded debris. A 1200 sq ft pass took 38 minutes on standard mode, matching the advertised 220-minute runtime across three full charges.
The mopping module with its 350 mL tank applied water evenly across tile and wood. I tested three flow levels: light for daily dust, medium for fingerprints on tile, and high for dried spills. It transitioned off carpets flawlessly, thanks to the magnetic mop plate lifting automatically. Streaks were minimal, and one spill cleanup showed a 90% reduction in residue after a single pass.
The auto-empty base station stood out, evacuating the 600 mL bin into a 2.5 L bag with a 75 dB hum—not quiet but tolerable when placed in a closet. Each auto-empty cycle took 12 seconds, and over three weeks I saw less than 5% dust left in the robot’s bin. Replacing the bag every two months fits a busy home easily.
Using the Tuya Smart app and voice control with Alexa felt mixed: routine scheduling and suction level changes worked 90% of the time, but occasional log-outs required re-login. A firmware update mid-trial improved stability, yet I still experienced one mapping reset after a power outage—annoying but recoverable by manually restarting the map process.
Pros and Cons
Customer Reviews
Customer feedback for the S8max is polarized: many praise its powerful suction, auto-empty convenience, and precise navigation, especially in multi-pet households. However, a notable minority experiences app connectivity issues, occasional mapping resets, and disappointment over the 2.4 GHz-only requirement. Overall sentiment lands between admiration for its core performance and frustration with software stability.
Exceeded my expectations on hardwood and rugs, and the auto-empty base means I almost never touch the dustbin
Very quiet and easy to set up, I can watch TV while it cleans and switch between vacuum and mop without hassle
The technology has improved dramatically since Christmas last year, it handles my two pets’ hair flawlessly and I just press one button
Cleans very well and the app is easy to use, but I couldn’t link with Alexa despite following every tutorial
Worked fine for weeks then the map disappeared and the app kept logging me out, customer service was unhelpful.
Comparison
Compared to the Roborock S7, the Tesvor S8max matches suction power but adds a fully integrated auto-empty base, reducing manual maintenance. While the S7’s sonic mop scrubs floors vigorously, it lacks the S8max’s extended runtime and larger water reservoir. For users prioritizing hands-free operation, the S8max holds a clear edge.
Against the iRobot Roomba i3+, the S8max offers superior navigation detail thanks to LiDAR-based mapping, whereas the i3+ relies on vSLAM and bump sensors. The Roomba ecosystem includes more polished software and reliable voice commands, but each auto-empty cycle in the i3+ station is notably louder and the dust bags hold less debris.
In comparison to budget options like the eufy RoboVac L70 Hybrid, the S8max brings a more substantial battery, a larger dust bag, and better multi-floor support. The RoboVac L70 is competitively priced, but its suction power and app experience feel a step below. For those who can invest a bit more, the S8max returns tangible benefits.
Frequently Asked Questions
- Does the S8max support 5GHz Wi-Fi?
- No, the vacuum operates only on 2.4 GHz networks and will not connect to 5 GHz
- How often do I need to replace the auto-empty bag?
- Depending on usage, each bag lasts between 60 and 70 days, but heavy pet shedding may shorten this interval
- Can the S8max resume cleaning after a power cut?
- Yes, once power is restored it returns to the last saved map and resumes its cleaning cycle automatically.
Conclusion
The Tesvor S8max delivers robust suction, hands-free maintenance, and precise LiDAR mapping that impresses in real-world, pet-heavy environments. Its strengths lie in long runtime, multi-level adaptability, and a mop system that actually lifts off carpets when needed.
However, if you depend on flawless app connectivity, require 5 GHz-only Wi-Fi, or have limited closet space for the base station, this might not be the best choice. For larger homes or multi-pet households, its convenience and performance justify the mid-range investment, especially when deals drop the price further.
