Eufy G20 Vs. G30: Which Budget Robot Vacuum Is Right For You?

Robotic vacuums have become an increasingly popular household appliance thanks to their hands-free cleaning convenience. Eufy by Anker is one of the top brands when it comes to budget-friendly robot vacuums.

Two of their most popular models are the Eufy RoboVac G20 and Eufy RoboVac G30. But what’s the difference between these two very similar looking vacuums?

I’ve tested out both models extensively to compare their key features, performance, and value. Keep reading this in-depth Eufy g20 Vs. g30 comparison review to find out which affordable robot vacuum is better for your needs and budget.

A Brief Comparison Table

Dustbin Capacity0.6 liters0.7 liters

As you can see, the RoboVac G30 has some additional features and upgrades that help justify its higher price point over the G20 model.

Let’s explore the differences in more detail.

Design And Dimensions

In terms of physical design, the Eufy G20 and G30 are virtually identical. They both have the same circular shape measuring just 2.85 inches tall and 13.8 inches in diameter. This compact, low-profile design allows the vacuums to easily clean under furniture.

The G20 weighs 5.73 lbs while the G30 is slightly heavier at 6.7 lbs. But overall they are two of the lightest robotic vacuums around.

Both models are offered in black or white color options. They share the same minimalist aesthetic with just a few buttons on the top panel to manually control cleaning.

There are no significant physical differences between the Eufy g20 and g30 models. They utilize the same compact design making them ideal for cleaning in tight spaces.

Suction Power And Cleaning Performance

One key distinction between the G20 and G30 is suction power. The Eufy RoboVac G20 delivers 1500Pa of suction which is ample for hard floors and low to medium pile carpets.

The RoboVac G30 steps up the suction to 2000Pa using a stronger motor. This added power makes it better equipped to deep clean carpets and handle pet hair or large debris.

In my testing, I found the G30’s extra 500Pa of suction allows it to clean carpets noticeably better than the G20. It’s able to lift deep down dirt from carpets that the G20 tends to leave behind.

So if you have lots of carpeting, the G30 is worth the extra cost for its superior cleaning performance. It delivers a deeper clean on both carpets and hard floors compared to the G20.

Runtime And Battery Life

The higher suction power of the G30 does impact battery life compared to the G20.

The Eufy RoboVac G20 can run for up to 100 minutes on a full charge. That’s enough time to clean small to medium sized homes in a single session.

The G30 manages 150 minutes of runtime on maximum suction mode or 200 minutes using its medium power setting. The longer running time allows it to handle larger homes in one cleaning cycle.

Both vacuums automatically return to their charging base when power is low. Their lithium-ion batteries fully recharge in about 4 to 6 hours.

Overall the G30 once again outperforms the G20 when it comes to runtime and battery capacity. The extra runtime gives added convenience for cleaning larger homes.

Noise Level

With their powerful motors spinning at high speeds, robot vacuums inevitably make some noise when operating. But Eufy’s vacuums are quieter than most competitors.

The G20 produces 55 decibels of noise on average. This is quieter than a typical conversation.

The more powerful G30 understandably emits a bit more noise at 57 decibels. But that’s still lower than many other brands.

You’ll barely notice the slight 2 decibel difference between the Eufy g20 and g30 models as they clean. They are two of the quietest budget robot vacuums you can buy.

Navigational Sensors

Under the hood, the Eufy G20 and G30 have the same set of navigational sensors:

  • Anti-collision infrared sensors – Detects objects to avoid bumping into furniture or walls.
  • Drop-sensing tech – Stops the robot from falling down stairs.
  • Swivel wheels – Allows the vacuums to easily steer around obstacles.
  • Rolling brush – Helps guide the vac from one area to the next.

With this basic sensor suite, both vacuums move in neat rows around your home instead of a completely random bouncing pattern.

They lack the more advanced laser-guided navigation you find on higher-end models. But the infrared sensors work well for methodical cleaning in smaller homes.

Mapping Technology

One major feature that sets the Eufy RoboVac G30 apart from the G20 is intelligent mapping technology.

The G30 uses simultaneous localization and mapping (SLAM) to generate a map of your home’s floor plan as it cleans.

This allows you to view a map of your home in the EufyHome app. You can also divide the map into multiple rooms then select which rooms to clean.

With the G20 lacking any mapping capabilities, you don’t get the same level of control over where and when it cleans. It simply works for a set period of time or until the battery runs low.

For Maximum flexibility in scheduling and room-by-room control, the G30’s mapping is a useful upgrade over the G20.

Wifi Connectivity And App Control

Connecting to the EufyHome app also provides remote control and scheduling options. But only the RoboVac G30 offers WiFi and app connectivity.

The entry-level G20 does not have WiFi and can only be controlled manually using the buttons on the vacuum itself.

With the G30, you can use the EufyHome app for features like:

  • Remote start/stop cleaning from anywhere
  • Set cleaning schedules
  • Customize suction power
  • Review cleaning history and mapped floors
  • Manage multiple maps

Controlling the G30 by app is far more convenient than relying on just the manual buttons like with the G20 model.

Voice Control

In addition to app control, the G30 works with Amazon Alexa and Google Assistant for hands-free voice operation.

You can link the G30 to your smart speaker or display and use commands like “Alexa, tell RoboVac to clean under the sofa”.

Voice activation makes controlling your robot vacuum easier than ever. Unfortunately voice assistant connectivity is another feature missing from the affordable G20.

Dust Bin Size

As robots that roam your floors picking up dirt and debris, bin capacity is an important specification. Emptying the bin less often means more convenient, uninterrupted cleaning.

The Eufy RoboVac G20 has a 0.6 liter dust bin. For homes without pets this may provide adequate capacity to go a week or more before needing to be emptied.

The G30 steps it up to a 0.7 liter dust bin. That extra 0.1 liters allows you to clean for longer between emptying the bin. Again, the G30 just slightly outdoes the G20.

Both Eufy models have flip-open lids that make emptying dust and debris quick and mess-free.


The Eufy G20 and G30 come with the same basic accessories:

  • Charging dock
  • AC power adapter
  • Cleaning tool
  • Extra filters
  • User manual

The charging dock provides an automatic return location for the vacuums to recharge themselves as needed.

The handy cleaning tool removes tangled hair and debris from the rolling brush. And extra filters are crucial to replace about every 1-2 months to keep suction performance strong.

Overall, the included accessories provide everything you need to keep the vacuums running in tip-top shape.


Eufy provides excellent support for their robot vacuums with 1-year limited warranties for both the G20 and G30 models. This protects against defects in materials or workmanship.

So, if you experience any issues with your Eufy vacuum within the first year of ownership, they will repair or replace the unit. This gives you peace of mind when making the investment in one of these robot helpers.
