Which is the best RoboVac robot vacuum from the Chinese brand? If you are not sure whether the G40 is a worthy upgrade from the G30, this is the place to be. We have compared all the important features that should inform your purchase decision.
There’s no doubt Eufy is one of the best robot vacuum brands in China. The company is known for its line of robot vacuums dubbed RoboVacs. If you are on a budget, the Eufy G30 T2250 and Eufy G40 T2255 should be on your wishlist. The two share quite a lot in common, but there are noticeable differences, hence the different model numbers.
The difference between the Eufy G30 and G40 is the cleaning performance. The RoboVac G40 has higher suction, translating into better vacuuming, especially on carpets. It is also compatible with RoboVac self-emptying technology, so you can forget about bin emptying for up to 60 days.
For more regarding how they compare, read along.
Face-to-Face Comparison Review
RoboVac G30 is a round-shaped robot vacuum with a low-profile design.
This design allows it to go under low-profile furniture such as sofas and beds and pass between tight spaces such as chair legs. The dimensions are 12.8 x 12.8 x 2.85 inches while the weight is 6 lbs.
When it comes to aesthetics, the G30 is really cool. It has 3 buttons and a WiFI signal on the top interface. The finish is black and striking blue.
The RoboVac G40 is also a round-shaped robot vacuum with a low profile, so you still get the same benefits as the G30.
It can creep under most low-profile furniture unrestricted and pass between tight spaces without getting stuck. The dimensions and weight are also quite similar.
It measures 12.8 x 12.8 x 2.85 inches and weighs 6 lbs too. The aesthetics are also similar. The G40 has 3 buttons and the WiFi signal LED and has been finished in black and blue.
There is no winner in this first round of this RoboVac G30 vs G40 comparison review. Both models are round-shaped and have a low-profile design. Besides, they have striking aesthetics.
RoboVac G30 (T2250) is a vacuum-only robot cleaner; it doesn’t have a mopping function. If you want the mopping function, consider any of the RoboVac Hybrid models, with the RoboVac G30 Hybrid as the best shot.
When it comes to cleaning specialization, the G30 is designed for all hard floors, from tile and linoleum to hardwood and marble, among many others. It is also suitable for low and medium pile carpets but struggles on high pile and thick carpets.
Besides hard floors and carpets, you can use the G30 as a robot vacuum for pet hair and other pet messes, such as skin flakes and kitty litter.
Like the RoboVac G30, the RoboVac G40 (T2255) is designed to vacuum only. It doesn’t come with a mopping function. If you are interested in a RoboVac that vacuums and mops, the RoboVac G40 Hybrid fits the bill.
On specialization, the G40 is also suitable for all hard floors, including tile, linoleum, vinyl, hardwood, marble, and so on. It is also a good robot vacuum for carpets and can handle low, medium, and high pile carpets.
If you have pets, don’t worry, as the RoboVac G40 is also a reliable robot vacuum for pet hair.
It is hard to call a winner in this round as both robot vacuums have the same cleaning orientation and specialization. But ultimately, the RoboVac G40 has the edge in terms of vacuuming, as we will see in our cleaning test results.
Like said earlier, the RoboVac G30 vacuums only. It leverages a 3-stage cleaning system where dirt is first agitated, lifted, and sucked into the bin in the final stage.
Eufy built the G30 with a powerful and efficient motor that delivers up to 2,000Pa to create the required suction. Interestingly, it has a unique feature dubbed BoostIQ Technology (2nd Gen).
This feature detects carpets and immediately steps up suction in a record 1.5 seconds for thorough vacuuming. In terms of operation noise, the G30 ranges between 55 dB and 68 dB.
The RoboVac G40 also relies on a 3-stage cleaning system where dirt is first agitated before being lifted and sucked into the bin.
But one difference between RoboVac G30 and G40 is the suction yield. The newer G40 has an upgraded motor that puts up a whopping 2,500 Pa when firing on all cylinders.
The BoostIQ (2nd Gen) function has been maintained, so if you have carpets, you can be sure of thorough vacuuming. The RoboVac G40’s operation noise levels are between 52 dB and 67 dB.
The RoboVac G30 and G40 both use a 3-stage cleaning system. However, the Eufy G40 is the round's winner, delivering more suction, 2,500Pa, than the G30's 2,000Pa.
The RoboVac G30, as mentioned earlier, doesn’t have a mopping function. Instead, consider getting the RoboVac G30 Hybrid.
RoboVac G40 also lacks the mopping function. Instead, you can get the RoboVac G40 Hybrid, a 2-in-1 robot cleaner.
There is no winner here, as both vacuums lack the mopping function.
RoboVac G30 is an entry-level robot vacuum with a pretty average navigation system based on an anti-collision and anti-drop system dubbed Smart Dynamic Navigation 2.0. The anti-collision system has over 9 sensors that detect obstacles with great precision.
Once an obstacle is detected, the robot slows down and changes direction. In the event it hits obstacles, the retractable bumper absorbs the impact. There are also anti-drop sensors that keep the robot off the stairs and other dangerous spots where it can topple off.
When it comes to maneuverability, the robot has two wheels with a 2/3-inch climbing threshold.
RoboVac G40 is also an entry-level robot vacuum with an average navigation system similar to the RoboVac G30’s – Smart Dynamic Navigation 2.0.
There is also an anti-collision system that has several sensors for obstacle detection. Once obstacles are detected, a message is sent to the main system for the robot to slow down and change course. The retractable bumper, on the other hand, comes in handy by absorbing impact when the robot hits obstacles.
The G40 also features anti-drop sensors to prevent the robot from toppling off the stairs. Regarding maneuverability, the G40 also comes with two wheels with a 2/3-inch climbing threshold.
As far as navigation is concerned, there is no winner, as both models have the same system. Though not very accurate in high-traffic rooms, they get the job done. That said, the round ends in a draw.
While the latest robot vacuums have intelligent floor scanning and mapping systems, the RoboVac G30 lacks any smart mapping system. Simply put, it does not scan your house or create maps to cover every inch.
Instead, it moves randomly in a zig-zag pattern. In a small room, it had no problem covering it entirely, but in large rooms, it missed some spots. But all the same, it did a great job.
Another shortcoming, it has no boundary marking feature, whether digital or physical, so you can’t contain your robot vacuum. Luckily, you can view the clean map reports on the app to see where the robot cleaned and didn’t.
Nothing changes in the RoboVac G40 as it is also not a smart mapping robot vacuum. The robot doesn’t create or save any maps.
Instead, it cleans randomly, a zig-zag pattern, to be precise. Like the G30, it had no problem covering the entirety in small rooms, but it missed a few spots here and there in large rooms.
If you are thinking of containment, I’m afraid the Eufy G40 doesn’t work with boundary strips or digital barriers. But we are glad you can still access the clean maps to know where the robot has cleaned and where it has not.
There is no winner here, as both robot vacuums use the same system. There is no smart mapping or boundary marking, but you get clean map reports via the app.
The Eufy G30 doesn’t just sweep and vacuum. It also helps to keep the atmosphere fresh. It has a unibody filter that captures 95% of allergens and other elements that may trigger allergies or cause bad odor.
Please note these are not true HEPA filters, as they capture down to 0.6 microns. For the record, true HEPA filters filter down to 0.3 microns.
The Eufy G40 can also help you keep your atmosphere fresh, not just sweeping and vacuuming floors and carpets.
It also has a high-efficiency filter that captures all allergens and unwanted elements. Again, we don’t have a true HEPA filter, but it still gets the job done.
There is no winner here, as both models have the same filter.
The RoboVac G30 comes with a 0.6L onboard bin that has to be emptied when full. Please note the G30 is not a self-emptying robot vacuum.
It is not compatible with the technology either, so your only option is manual emptying.
RoboVac G40 also features a 0.6L onboard bin that requires frequent maintenance. But you can opt for the Eufy G40+, a self-emptying robot vacuum.
Another option is buying the empty station separately if you have the G40. You can forget about bin emptying for up to 60 days.
There is no winner here, as both models come with the same 0.6L bin. However, the G40 is the ultimate deal now that it is compatible with the auto-empty station.
To agitate dirt, the G30 is equipped with a spiral bristle floating brush that sweeps and lifts dirt, ready to meet the super suction that sends the dirt and debris straight to the bin.
This brush is very effective yet gentle on fragile floors. It is complemented by a single spinning brush on one side that sweeps the wall edges and deep corners.
The RoboVac G40 also has a spiral bristle floating main brush for agitation and dirt lift-up.
It is also complemented by a spinning side brush designed to reach the deep corners and wall edges.
Again, it is a draw as both models come with the same brush system.
The RoboVac G30 comes with a rechargeable lithium-ion battery. Anker opted for a lithium-ion battery because of its high capacity and endurance.
The G30 packs a 2600mAh Li-ion battery, offering up to 100 minutes of runtime on hard floors. However, on carpets, suction is higher, and consequently, runtime dips to around 70-80 minutes, depending on the carpet pile.
Regarding power management, the RoboVac G30 is an intelligent robot vacuum with an auto-recharge and auto-resume function. The average recharge time is 6 hours.
The RoboVac G40 is not different. It is also equipped with a lithium-ion battery with a 2600mAh capacity. The battery offers up to 100 minutes of runtime on hard floors, as BoostIQ is not activated.
However, on carpets, BoostIQ activates, and this is what drops the runtime to 70-80 minutes which is still enough to get the job done if it starts the cleaning session on a full charge.
Like the G30, the G40 is also a smart robot vacuum that recharges automatically and resumes cleaning without being prompted. Recharge time averages 6 hours.
In this round, there is no winner as both robot vacuums come with the same 2,600mAh lithium-ion battery and have auto-recharge+resume function.
Despite being an entry-level robot vacuum, the RoboVac G30 is a smart robotic home cleaner with several automation features. The Eufy G30 has 2 cleaning modes; Auto and Spot.
Besides, a schedule function lets you program the robot to clean throughout the week at specific times. The G30 is powered by 2.4GHz WiFi, allowing mobile operation via the RoboVac Home App.
On the app, you have all controls on your palm. The G30 is also compatible with voice assistants such as Alexa and Google Assistant.
RoboVac G40 is also a smart robot vacuum. It comes with Auto mode for general cleaning and Spot mode that focuses on cleaning spots with concentrated dirt.
We also have a schedule function so you can also plan the robot in advance and forget about floor cleaning.
Like the G30, the G40 is also compatible with 2.4GHz WiFi for remote operation via the mobile app or any popular voice assistants, talk of Alexa and Google Assistant.
There is no winner here as both RoboVac G30 and G40 have 2 cleaning modes, have a weekly schedule function, and support mobile app and voice assistant remote operation.
Eufy is known for durable robot vacuums and further earns customers’ trust by accompanying the RoboVac G30 with a 12 months warranty.
In case the robot fails within the first year of purchase and you have adhered to the warranty’s terms and conditions, you are eligible for repair or replacement.
Regarding customer support, we are glad Eufy has robust customer support that responds to queries on time. Last, replacement parts and supplies are readily available, both original and generic.
Like the RoboVac G30, the RoboVac G40 is also covered by a 12 months warranty.
You can be sure of getting repair or replacement during the first year if the problem is related to a manufacturer’s defect and you have not voided the warranty. Customer support is also available, so whether you are stuck syncing your robot to your home WiFi or have any other problem, help is available.
Replacement parts and supplies, from broken components to filters and brushes, are available at affordable prices.
There is no winner in this round, as both robot vacuums are from the same brand. They come with the same 12 months warranty, support is available, and so are replacement parts and supplies.
The Eufy RoboVac G30 comes with the following:
- RoboVac G30
- Charging base
- AC power adapter
- 2 side brushes
- Extra filter
- Cleaning tool
- 5 Cable ties
- Welcome guide
- Warranty card

- RoboVac G40
- Charging base
- AC power adapter
- 2 side brushes
- Extra filter
- Cleaning tool
- 5 Cable ties
- Welcome guide
- Warranty card
There is no winner here, as both robot vacuums are well-equipped with everything they need to get the job done. But ultimately, you'd want to go with the second package as it comes with a more advanced robot vacuum.
