The Quick Verdict: MAMNV D13S Max
The MAMNV D13S Max is an ultra-budget robot vacuum and mop combo with features that used to be rare at this price, including LiDAR navigation and an auto-empty dock. In our testing, it delivered surprisingly strong vacuuming power, excellent airflow, above-average carpet deep cleaning, and very efficient navigation. The trade-offs were significant. Its mopping and hair tangle performance were both poor, it does not have true obstacle avoidance, and the onboard dustbin is extremely small. It is not one of our top budget picks, but it may still appeal to shoppers who want strong vacuuming and LiDAR navigation for the lowest possible price.

MAMNV D13S Max Robot Vacuum Mop Combo Review
The MAMNV D13S Max is an ultra-budget robot vacuum and mop combo that offers two features rarely seen together at this price: LiDAR navigation and an auto-empty dock. Those features used to be limited mostly to more expensive models, but smaller and lesser-known brands are starting to bring them into much lower price ranges.
We bought the D13S Max and put it through our standard robot vacuum testing protocol to see what this model is actually capable of. The results were mixed but interesting. It delivered surprisingly strong vacuuming power and navigation efficiency, but its mopping performance, hair-tangle results, and lack of true obstacle avoidance showed where the low price still comes with real trade-offs.
In this review, we’ll go over the pros and cons, where the D13S Max performed better than expected, and where the low price clearly comes with trade-offs.
MAMNV D13S Max Basics
Starting with the basics, the D13S Max is a robot vacuum and mop combo with an auto-empty dustbin in the dock and LiDAR navigation. This is one of the least expensive robot vacuums with these features on the market. LiDAR and an auto-empty bin used to be completely unheard of at this price, but we’re starting to see these appear on smaller, more generic brands.
That feature mix is what makes the D13S Max interesting. It is not trying to compete with premium robots on obstacle avoidance, app polish, mopping performance, or brand ecosystem. Instead, it is offering a few previously higher-end hardware features at a very low price.
Why You Can Trust Vacuum Wars Robot Vacuum Reviews
Vacuum Wars stays 100% independent and reader-supported. We buy every robot vacuum ourselves and test each one under identical lab conditions — no freebies, no sponsorships, no outside influence. Our reviews are driven entirely by data from our standardized performance tests.
Vacuuming Performance
The most obvious pro with this model is its vacuuming performance. In terms of raw power, the D13S Max generated 2.64 kPa of suction, earning the 10th-highest suction score in our testing. That’s especially impressive considering our database includes more than 180 robot vacuums.
Its airflow performance was also strong, measuring 21 CFM, compared to our 17 CFM average. This places it among the best airflow results we’ve recorded, showing that the D13S Max delivers surprisingly powerful cleaning performance for such an affordable robot vacuum.
It did a good job of sweeping debris of different sizes from the surfaces of both hard floors and carpets, with a little scattering on hard floors that resolved on the second pass.
It also did well in our carpet deep clean test, where we put sand into medium-pile carpet and measure how much the vacuum can remove. This model scored way above our testing average of 78%, removing 87% of the sand.
Bottom Line: Vacuuming was the strongest part of the D13S Max. Its suction, airflow, and carpet deep-cleaning results were much better than we expected from an ultra-budget robot vacuum.
Pet Hair Pickup
We also tested it on our flattened pet hair test, where we press 2.5-inch hair onto carpets and measure how much the vacuum is able to lift up. It hit right at the average with 82%, which was an acceptable performance, even if it wasn’t its strongest category.
That result is worth separating from the hair-tangle result, which we will cover later. The D13S Max could pick up flattened pet hair at an acceptable level, but it did not manage long hair well when it came to wrapping around the brush.
LiDAR Navigation
Navigation was another surprising pro on this model. The D13S Max has a top-mounted LiDAR turret for its navigation. The navigation system allows for multi-floor mapping, which is a nice bonus for homes with multiple levels.
And in terms of navigation efficiency, it really delivered, with .94 square meters per minute, the fifth highest score we’ve seen. That is a major strength for a robot in this price class. Budget robots often cut corners on navigation, but the D13S Max was able to move efficiently through our test area.
Bottom Line: Navigation was another standout result. The D13S Max delivered unusually efficient navigation for a robot at this price point.
Auto-Empty Dock
Another big pro is the auto-empty dock. It’s a feature that catches our eye at this price point, and it buys the user a little time before having to deal with dustbin debris. The base station claims up to 10 weeks of dust storage before having to replace the 3.5 L disposable bag, depending on the volume of debris.
Basic Mopping Feature
The fact that this model has a mopping feature is another pro, at least on paper. The mop is a basic flat-pad design with a detachable water tank. It doesn’t have any scrubbing or downward pressure features, and it will not lift over carpets, so vacuuming and mopping need to happen in separate runs. This is a very basic form of mopping, and it is common to see it on earlier robots and budget models.
The mopping performance itself is another matter, which we’ll cover in a moment when we get to the cons.
Budget Robot Vacuum Trade-Offs
Before we get into the main cons, there are a few things that are not really cons exactly, but they are trade-offs for a budget robot vacuum.
Lack of Obstacle Avoidance
First, there is no obstacle avoidance on this model. We wouldn’t expect there to be any at this price, but some of the marketing materials on the website make this a little confusing. The LiDAR sensors used for navigation can detect large obstacles like walls and high-profile furniture, but obstacle avoidance helps a robot sense smaller objects like toys or cables. You’ll need to do some tidying before you run it, because there will be no reliable detection for smaller floor clutter.
Lightweight App Features
Another trade-off is that the app is more lightweight than what you usually see from a larger brand-name robot vacuum company. The app is supported by Tuya, which is a platform smaller brands will often use as an economical way to build an app without developing one from scratch.
It supports no-go zones, scheduling, and map editing, and it can be integrated with third-party voice assistants like Alexa and Google. That is a solid feature set for the price, but it is not the same kind of polished, brand-specific app ecosystem you would expect from a major robot vacuum manufacturer.
Mopping Performance was Concerning
The biggest con with this model was its mopping performance. It was incredibly poor.
In our new coffee stain test, where the average score is 94 points, the D13S Max scored in the single digits. This was the second-worst stain score of all time after the Tikom L8000 Plus.
The bad stain removal did not seem to be because of low water output, since it had a higher-than-average water penalty score, leaving behind more water than we like to see at 1.7 grams compared to the average of .95 gram.

The combined mopping score, when we take into account both the stain score and the water penalty, was the second-worst overall mopping score of all time, with a score of -.05 compared to an average of 20.3. You might want to think of it as essentially a vacuum-only robot, since any mess that needs more than a light wipe-down will be more than the robot can handle.
Bottom Line: Mopping was the D13S Max’s biggest weakness. Despite having a mop attachment, its stain removal and combined mopping score were among the worst we’ve tested.

No Tangle Resistance
Another con was in our hair-tangle test. This model does not advertise any tangle resistance, and for good reason. In our 7-inch hair-tangle test, we found that 50% of the hair wrapped around the main brush, almost twice as much as the average in our data set.
Hair wrapping at this level can strain the motor and make the brush less effective at agitating the floor, so it is something users will want to keep an eye on.
Bottom Line: The D13S Max is not a strong choice for homes with lots of long hair unless users are willing to clean the brush frequently.
Small Dustbin
Finally, the dustbin is extremely small, more than 40% smaller than average. This can be an issue for homes with large amounts of pet hair or other bulky debris, and it can make the dustbin overfill before the robot gets back to the dock to empty.
That matters even with an auto-empty base. The dock can reduce how often users need to empty debris manually, but the robot still has to make it back to the dock before the onboard bin overfills.
For homes with pets or heavy debris loads, that small onboard bin could become a practical limitation.
Final Verdict
The MAMNV D13S Max did not wind up as one of our favorite robots, or even as one of our top budget picks. But honestly, it had some really strong points. If you’re looking for a robot that has good vacuuming and navigation, and you are not too worried about mopping, it can deliver those things for a very low price.
What’s interesting about models like these is that some of the technologies that were cutting-edge on name-brand flagships a few years ago are now showing up at the most budget end of the robot vacuum price range.
At the same time, the trade-offs are real. Critical reviews suggest durability concerns, and many people noticed the mopping issues and the absence of obstacle avoidance, which might be a surprise to some users given the way the robot is advertised.
The best way to think about the D13S Max is as an ultra-budget vacuum-focused robot with LiDAR navigation and an auto-empty dock, not as a fully capable robot vacuum and mop combo.
For the right user, that could still be enough. But if you want better mopping, stronger hair management, true obstacle avoidance, or a more polished brand ecosystem, there are stronger options available.
