Bambu AMS Compatibility
Since October 2023, the 3D-Fuel Standard PLA+ has been manufactured using an AMS-compliant spool (more info on our spool sizes and weights). Since it takes time for some colors to move through our warehouse inventory, you may receive an older spool type. This is still compatible with the AMS, but you must leave the lid open a few mm.
Pro PCTG is 20-50% More Impact Resistant Than PETG
Key Reasons for Better Impact Toughness:
-
Molecular Structure:
- PCTG contains cyclohexane dimethanol (CHDM), which gives it increased flexibility and toughness compared to PETG’s ethylene glycol structure.
-
Flexibility vs. Brittleness:
- PCTG is more ductile, allowing it to absorb and dissipate energy during impact without cracking or shattering.
-
Layer Adhesion:
- PCTG has better inter-layer bonding when 3D printed, reducing weak points in the structure where impact forces might cause failure.
Real-World Implications:
-
Drop Resistance:
- PCTG parts are less likely to crack, chip, or break when dropped, making it ideal for high-impact applications like enclosures or wearable devices.
-
Repeated Stress:
- PCTG can endure repeated bending or sudden forces better than PETG, making it more suitable for hinges, clips, and flexible parts.
-
Durability in Extreme Conditions:
- PCTG resists embrittlement under low temperatures, maintaining its toughness in environments where PETG may fail.
Example Use Cases Benefiting from PCTG's Toughness:
- Protective housings for electronics or tools.
- Drone parts and propeller guards.
- Flexible clips, snap-fits, and living hinges.
- Impact-resistant containers or enclosures.
Chemical Resistance
| Chemical Type | Examples | PCTG Advantage | PETG Limitation | Comparison (CRR) |
|---|---|---|---|---|
| Alcohols | Isopropyl alcohol (IPA), ethanol, methanol | Resists prolonged exposure without degrading or cracking. | Degrades or stress cracks with high alcohol concentrations over time. | 1.8 |
| Hydrocarbons | Hexane, heptane, gasoline, mineral spirits | Better resistance to hydrocarbon-based solvents. | Softens or weakens when exposed to hydrocarbons. | 2.0 |
| Acids | Acetic acid, citric acid, phosphoric acid | Maintains structural integrity in mild to moderately concentrated acids. | Degrades faster in acidic environments at higher concentrations. | 1.4 |
| Bases (Alkalis) | Sodium hydroxide, potassium hydroxide, ammonium hydroxide | Better resistance to strong alkalis. | May crack or degrade when exposed to strong bases. | 1.33 |
| Cleaning Agents | Bleach (sodium hypochlorite), industrial degreasers, detergent solutions | Withstands harsh cleaning agents without discoloration or damage. | Discolors, cracks, or loses properties with harsh cleaning agents over time. | 1.5 |
| Oils and Lubricants | Engine oils, hydraulic fluids, cutting oils | Resists degradation from prolonged exposure to oils. | Absorbs oils over time, potentially leading to swelling or weakening. | 1.6 |
| Ketones | Acetone, methyl ethyl ketone (MEK) | Performs slightly better in low-concentration ketones. | Softens or dissolves more readily in ketone-rich environments. | 1.2 |
Pro PCTG Has Lower Moisture Absorption Than PETG
-
PETG:
- Hygroscopic: PETG absorbs moisture from the air, but at a relatively low rate compared to more hygroscopic materials like nylon or TPU.
- Moisture Absorption Rate: Approximately 0.2–0.3% by weight after prolonged exposure to humid environments.
-
Effects of Moisture:
- During printing, moisture in PETG can lead to stringing, bubbling, and surface defects due to water vaporizing in the hotend.
- Mechanical properties (like impact strength) can slightly degrade over time with prolonged exposure to high humidity.
-
PCTG:
- Slightly Lower Moisture Absorption: PCTG absorbs less moisture than PETG, typically around 0.1–0.2% by weight.
- Improved Resistance: Due to its cyclohexane dimethanol (CHDM) component, PCTG’s molecular structure makes it less hygroscopic and more resistant to moisture-induced degradation.
-
Effects of Moisture:
- PCTG generally performs better than PETG in humid conditions, retaining clarity, toughness, and dimensional stability for longer periods.
Why the Difference?
-
Molecular Structure:
- PETG’s glycol modification increases flexibility but leaves the material slightly more hygroscopic.
- PCTG’s modified structure with CHDM reduces the polar sites available for moisture interaction, resulting in less absorption.
Practical Implications:
-
3D Printing:
- PETG: Requires drying more frequently, especially if exposed to humid environments, as even slight moisture absorption can lead to print defects (bubbling, stringing, poor adhesion).
- PCTG: Requires less frequent drying, making it easier to handle in environments with higher humidity. It is also more forgiving if printed without drying.
-
Storage:
- Both materials benefit from being stored in airtight containers with desiccant.
- PCTG will be less prone to degradation if exposed to moisture for extended periods compared to PETG.
-
Long-Term Use in Humid Environments:
- PCTG is more stable and less likely to lose mechanical properties over time in high-humidity settings.
Drying
For both materials, drying before printing and proper storage is recommended for optimal performance, but PCTG is less maintenance-intensive in this regard.
When you need to dry Pro PCTG, use a temperature of 60-70C for 4-8 hours.

A phenomenol piece of tech... outclasses any and all other vacs I have ever owned...
Color: Black01
This was almost a revenge purchase in response to a frustrating year we had after moving on to a Eufy which was a complete dud. the Eufy, while advanced and not low end, managed to barely finish 40% of the cleaning jobs without getting stuck on something. Prior to this, I've had Roomba 200 series and Neato vacs which I had been very happy with, but those weren't very advanced.
In comes the Roborock Qrevo... this thing was the answer to our prayers. Its *quiet*, powerful, and most importantly, it FINISHES THE JOB. While its not perfect, the Roborock can finish cleaning the house around 80-90% of the time without help. Its base operates just fine, and the mapping system is the best I've seen. With the Eufy, the map seemed to mean nothing... if the robot got stuck, you cleaned it, and placed it back down a little further away from where it was it would get lost. The Roborock on the other hand does an amazing job at map registration, even with significant moves of the robot for any reason (including our toddler picking it up and dropping it elsewhere). Also, in praise of the mapping system, it does an amazing job capturing various levels of detail such as the location of rugs (relative to the hard wood floor) and other aspects of the home.
The app is also very nicely done, as is the power management. This thing is really designed as a >$800 robot vacuum, that you can get on sale for $400.
My recommendation is to BUY IT.

Impressive Cleaning, but not quite perfect
UPDATE BELOW INITIAL REVIEW
This is an impression after having run 6 sessions total over the span of two days on a 3 story home, two days after product release.
I want to get something out of the way first: I have never owned a robovac; I have friends that have and I have witnessed them in action, but not my own. I recently moved into a big home with my SO and we quickly realized we would need some serious cleaning assistance. I set off in search of a good robovac, scouring the internet for hours over a week. Everything pointed to this vacuum.
I read some pretty unbelievable reviews, and let me tell you they're not entirely accurate from my experience, but pretty darn close.
Upon setting up my S7 MaxV I was immediately greeted with a firmware update, which went without a hitch and provided a changelog. Good sign, as this means that we should be able to expect OTA improvement over time. I have very long hair, we have no pets, but we leave a lot of things around the house and there are a lot of potential things to hit and get stuck on such as standing fans, chairs, tables, electronics, metal floor vents, etc for the vac to interact with on every floor. Everything this vacuum promises lives up to expectations, but there are a few caveats. It will get hung up on some things, still, such as metal floor heater grates and long Ethernet (any really) cables stretched across the floor, and it is definitely not immune to the amazing power of long hair and it's evil tangling powers. That said, it is surprising easy to remove long hair from both the side and middle brushes, albeit I did have to carefully cut the hair on the middle brush to get most of it off.
As to cleaning, it's incredible on all surfaces. You can really hear the power of the vacuum roar to life on carpet, where it auto switches to higher suction when moving off another surface. Not much to say here other than things were spotless after it mopped and vacuumed about 66sq meters in 1hr, including underneath large objects. Way better than me!
Obstacle avoidance is almost flawless, I didn't really need to monitor this at all. Additionally, it detected stairs very well.
The video camera and call functions are pretty neat, but don't expect too much out of them as it's mostly a gimmick. Fun though!
There's just so much to say but I will cut to the chase: this robovac is freaking incredible. I am extremely satisfied with my purchase, and am excited for the ultra dock that supposedly comes out next month. If you are on the fence, this robovac is well worth it! That said, it is extremely expensive but if you can shell it out you will likely be satisfied, too!
---UPDATE AS OF May 12 2022:
The robovac is working as great as ever for it's main purpose--cleaning. Maintenance has been am absolute breeze; after three to six runs you empty the dustbin and after every mop you clean it. As mentioned above, I have long hair so I occasionally need to take out the main and side brushes, but cleaning these takes about 2 minutes. Refilling the water tank with distilled water takes about 10 seconds. I've noticed that a few features don't work properly, even with perfect signal (wifi or cell), such as the calling and remote viewing features. It's simply will not display the video no matter what I do. At one point I was able to get it to work by cycling my Wi-Fi and cellular a bunch of times and eventually it showed. I have not tested this on iOS, but at least on Android it does not work properly. Additionally the vacuum has managed to lose its main brush on a metal floor transition strip. My theory is that it got caught on the nails holding the strip. Honestly this was a pretty minor inconvenience. I still think this robot vacuum deserves four stars, however there are a few things I would really like to have:
1. An undo button on the map, as well as an option to manually erase parts of mapped areas (think like the eraser tool in your favorite image editor). As someone that has quite a few full sliding door mirrors, the robot vacuum loves to see "into them" and see those "inside mirror parts as part of the room. This has led it to bleed into other rooms which has led me to have to remap. Minor inconvenience as it's fixable by putting down things to block the robots view of the mirror but rather annoying.
2. An option to disable the mop without removing it. While I generally like it to mop, sometimes I just don't need it for what I needed to do.
Overall great product, would buy more from Roborock.

Excellent Choice In A Reasonably Priced Robot Floor Cleaner
Color: Black01, Color: Black01
This review is for the Roborock QV3a. After hearing my brother-in-law rave about his robot vacuum, I hesitantly bought this. I was hesitant because I had purchased one many years before, and it had been virtually useless. It only vacuumed, was loud with minimal suction, banging its way around and it constantly got clogged with debris and eventually ended up at Goodwill. This vacuum does a wonderful job both vacuuming and mopping, competing with models that cost three times as much. After creating four different maps, the first map, map with the 1st floor family room, kitchen and dining room room all on one level, I segregated an area of the kitchen that gets very dirty after cooking, to allow me to do a daily vacuuming and mopping of this area. The second map included a living room off of our raised entry hall. The third map included the raised tiled entry hall. The fourth map included the second level of the house, including three bedrooms and a large balcony.We have biweekly housekeeping, so most of yhe areas of the house, including a carpeted living room, tile entry hall, living room, 4 bedrooms and balcony, only require vacuuming as needed, often once in the week we don’t have housekeeping. After completing a cleaning of the whole house I was very impressed. It thoroughly cleaned including under furniture picking up an amazing amount of dust bunnies. Our regular vacuum did not fit under dressers, couch, couches, etc. Mopping the tile areas resulted in very clean floors. I did established some no go areas to keep the vacuum from hitting areas with a large number of cords. I also created no go areas under the beds and a couple dressers. Avoiding these areas, greatly speeds up the cleaning process. It is easy to establish no go areas. I can delete them a couple times a year to clean under furniture. I also put up an invisible line on the railing in our balcony, the robot did not see this as a wall, and it would feel its way along the railing, greatly slowing the cleaning process. The robot does seems to learn each time it cleans finding a more efficient way to clean. I also found that moving the chairs away from the dining room table slightly allowed the robot to clean under the table much faster. Our family room has a very large area rug in it with hardwood floors throughout. The robot was able to identify the rug area, mopping/vacuuming hardwood floors and vacuuming the area rug. The app is very intuitive easily allowing the establishment of no goes zones or invisible walls. To clean, simply restore the map for the area you want to clean, select the area you want to clean, and choose your cleaning mode of mopping, vacuuming, or both. It is very simple to use. When done the robot empties the dirty water, cleans the mopping pads, and empties the dust bin. I am very happy with my purchase. For anyone that wants to purchase a cleaning robot without spending $1000 or more, this is an excellent choice. Update: after over 30 hours of use I am still pleased with this robotic floor cleaner. Use daily to keep kitchen tile floor vacuumed. Mop cycle cleans tiles as well as a mop using highest water setting. Also great for cleaning hardwood floor and carpet. Great value for the price. No problems to report. Buy one!

Absolute Yes for Me
Color: Black
The kids have named our vacuum ROB. And ROB is a total Workhorse. Extremely simple setup, in my opinion. Caveat: it does not work or sync with 5g signal, but it will still work generally. In other words, it will still work the same, but will not remember floor layouts. So each time you turn it on, it is not following a learned “map”. If you’re okay with it not following that map each time, then this vacuum will take great care of your floors. In my opinion, this does not affect the functionality. The Lefant Vac is impressive. It doesn’t stop at hard flooring, either— it crosses over transition strips to low- medium pile carpet and does a great job keeping the carpet clean as well. The battery life is also impressive— going for a couple hours before returning to the charging station. I can still program it to clean at certain times, but I don’t use that option. The suction power is excellent, and it has picked up long hair fur from my ex’s German Shepherd that my upright vacuum didn’t catch. Noise level is fine. I’m not losing my mind over it at all. In fact, after a few minutes of it running, I’ve forgotten all about it until it returns to the dock. ROB is able to maneuver very well around furniture and doorways. Just make sure you don’t leave anything on the floor that you don’t want sucked up. Because it will get EVERYTHING in its way. I purchased this vacuum on sale back in November 2025 and I’m so glad I took a chance on it. Best thing I’ve ordered in a while and the price couldn’t be beat. Far superior to my old Roomba. I haven’t used the wet mop setting yet since I haven’t needed it— couldn’t tell you how well that works. The dirt canister is pretty easy to empty, but bring the whole vacuum to the garbage can to empty since it can get kind of messy the first couple times you empty it, especially depending on how much dirt it’s picked up. I bought this robot vacuum for my vinyl kitchen flooring, but once I realized it was able to do far more and had conquered my medium pile carpet just as easily, the is vacuum regularly cleans my entire downstairs flooring in one charge. Jump on this if you can. I highly recommend this vacuum

A very good product, which fulfills its purpose and even more so if bought on sale.
Color: Black
I bought the vacuum cleaner from abroad, without really knowing it or having seen it, only from the reviews I read on Amazon. The product arrived perfectly packaged, on time and in perfect condition.
The manual is simple and has clear instructions, correctly translated from Chinese to English, so it wasn't difficult to get it up and running. It came with everything the box stated: charger, cable, mop liquid container, floor mop, two sets of brushes, and a HEPA filter. This same filter has a very thin foam filter, which unfortunately broke the third time I cleaned it with a brush: this seems to be normal, and the brand should review its specifications.
It's essential to place the base in a location where the device can be easily returned and where there aren't too many clutter around it to avoid problems. Install Lefant's proprietary app, and following the step-by-step instructions makes it easy to connect to Wi-Fi and your cell phone. This allows you not only to give commands to the robot but also to schedule different cleanings, check the map the vacuum cleaner is creating, etc.
Regarding the location system, the LIDAR is really good at generating a real-time map as it scans the terrain the first time we turn it on; that's why it's essential to choose the right resting and charging location, otherwise we'll have to redo the map if we move it. As the vacuum cleaner moves, it generates this map that automatically detects the rooms, although it also has an editing system that allows it to do this, determining the cleaning order for each room, blocking off areas, etc. The map is updated with each pass the robot makes, and the phone's software is responsible for correctly "determining" some lines on it, as well as independent spaces. One detail: in my case, the vacuum cleaner thinks the space under the main bed is another room, so I can ask it to clean the entire room or just that space.
Cleaning is effective, with two effective brushes and adequate suction power for daily, non-deep cleaning. It has three power levels: a quiet one, a normal one, and a powerful one. Generally speaking, normal vacuuming is enough for an average home with the usual crumbs, dust, and pet hair. In this regard, I have a long-haired cat, and it's noticeable how time and again when the robot vacuums, I find tons of loose hair and dirt: this situation has really improved in my home. The battery life is adequate, although in a 50 square meter area, I've seen that when using the highest suction power, when it reaches 60% of the remaining battery, it decides to recharge (I don't know why or if it's a programming glitch).
If you have long-pile carpets, it's advisable to lift them off the floor and not let the vacuum cleaner pass near or over them, as the brushes get tangled in the long hair, causing it to jam and prevent it from cleaning further. Although it has a carpet mode, it's designed for hard and short-pile carpets, where it basically increases the suction power. But, again, this is a problem with long-pile carpets. Regarding this, when the vacuum cleaner gets stuck or detects a situation it can't resolve, it emits a voice alert clarifying the situation, and a notification is sent to the phone, more specifically to the dedicated app. This app is very comprehensive and allows you to view real-time and aggregated statistics on the robot's work. I must say that the Chinese to English translation is better than the Spanish one, so I recommend using it in English.
I haven't used the mop enough to comment, but from the little I've used it, it's accurate in terms of the amount of liquid and the way it's distributed. You can add some kind of cleaner, as long as it's light, not sticky, and doesn't leave residue.
In conclusion, it's a purchase I recommend, a good product that fulfills its purpose. If I could improve it, I would make it come with a larger number of spare parts or make them easier to purchase, since it doesn't have much information and when looking for them, you have to rely on other brands or models.
