Does Eufy Slow Down Wi-Fi Speed? (We Checked – Solved)

Does Eufy slow down Wi-Fi speed? That’s the question we’re going to answer today.

If you don’t know Eufy, it’s a brand of robot vacuums and other home appliances that started out as a Kickstarter project by Anker.

The idea behind Eufy was to create inexpensive robot vacuum cleaners that would still clean your floors well, as well as other home appliances.

In this article, we’ll explain if a Eufy robot vacuum can slow down your Wi-Fi speed and what you can do about it.

Here’s If Eufy Slows Down Your Wi-Fi

I’m gonna go ahead and say: it does. If it’s connected via ethernet (hardwired), the most it will use is 1MB per minute. That’s a negligible amount of data. You’re probably not even going to see a difference in your daily usage.

Eufy doesn’t broadcast its own wireless signal like most Wi-Fi cameras do, so because of that, you shouldn’t experience any interference or slowdown with other devices on the same network.

So long as your router is functioning properly, the only thing you’ll really notice about Eufy is that it provides clear video footage for you to review when needed (or watch live).

As an avid user of Wi-Fi, you might be wondering this. Perhaps you’ve even bought a Eufy product and are experiencing slower speeds than before. Well, don’t worry. We’ll clear this up for you.

Yep. It’s true. Eufy does slow down your Wi-Fi speed—but only slightly. If you’re using a single Eufy device, your download speed will be reduced by at most 1 Mbps (Megabits per second) and up to 6 Mbps if you have multiple devices connected at once.

However, it may be unnoticeable as the average US download speed is around 52 Mbps (Source: Speedtest).

This is because the transmission standards used by Wi-Fi and Eufy have slight differences in their respective channel widths and overlaps, meaning that some of the same frequencies are used by both technologies.

The solution? Make sure to use different channels for your Wi-Fi router and Eufy devices so that they aren’t competing for the same frequency space. 

How Come My Wi-Fi Is Slower When Using Eufy?

If you’re trying to stream video while your bot is cleaning, it might be hogging too much bandwidth, resulting in slower internet speeds. If this is the case, try temporarily disabling streaming until the robot has finished cleaning.
Signal interference

Some old routers have weaker signals that suffer from more interference than newer models. And guess what? Your

Eufy can interfere with your signal if it’s operating on older technology or if it’s not set up quite right for your network and devices. Ensure that your router is close enough to activate all of its ports and try moving things around so that there isn’t anything interfering with its signal:

  • Weak signal strength (Wi-Fi dead zones)
  • If you’ve got areas of your home where Wi-Fi doesn’t reach very well, then even an awesomely powerful device like Eufy will slow everything down—and annoy everyone in earshot while they’re trying to watch their favorite show on Netflix or
  • YouTube (not that we’d know what their favorite show is).

Can Using Eufy Directly Affect My Wi-Fi Speed?

Because your Eufy camera uses both 2.4GHz and 5GHz frequencies, it can affect your Wi-Fi speed if you use the same band for your Wi-Fi router.

It also uses a fixed frequency for each camera. There are roughly 14 channels in the 2.4 GHz spectrum, but only 3 non-overlapping channels.

This means that if two or more devices use the same channel, they will interfere with each other’s signals.

To fix this issue, you can do one of three things:

  • If possible, place your Eufy cameras on different floor levels to maximize distance between them and reduce interference
  • If it isn’t possible to separate them physically (or if you have too many cameras), try changing their 2.4 GHz bands so that they are not using overlapping channels
  • Switch from a 2.4 GHz router band to a 5 GHz router band (if applicable)

If you are using a Wi-Fi router and have multiple devices that are usually connected to the internet via a Wi-Fi connection, you will know how important it is to keep your connection fast and stable. Even if you are not looking for speed always, it is necessary to keep a good connection between all the devices in your home.

Sometimes the Wi-Fi connections may be slower than usual and could cause problems when you are trying to use the internet on any device.

One of the reasons that this happens is because of interference from other electronic devices such as cordless phones, baby monitors, wireless speakers etc.

Another reason why your connection could slow down is because of your own device being too far away from the wireless router or modem. This can also happen if there are walls or other obstacles between your device and the router.

There are times where you might experience this problem even after making changes to your setup and still have slow connections.

What causes this? This could be due to interference from other electronic devices such as cordless phones, baby monitors, wireless speakers etc.

Another reason why your connection could slow down is because of your own device being too far away from the wireless router or modem.

How Do I Check If It Interferes With My Wi-Fi Connection?

To find out if Eufy is slowing down the speed of your Wi-Fi connection, you should run a few tests.

First, download a speed test app to your phone. I recommend using

Make sure that you are testing the actual speed of your Wi-Fi network, not just how fast your phone can download a webpage over 3G or 4G LTE (if available). So be sure to connect to your home wireless network before running each test, and then disconnect from it when you are ready to switch modes (Eufy on vs Eufy off).

How Much Bandwith Does Eufy Use?

Now that we have a basic understanding of how Eufy works, let’s talk about the impact that it has on your bandwidth.
As I’ve already explained, Eufy is not recording anything and uploading any footage to the cloud. Instead, if a motion event is detected, your camera will stream small amounts of video directly to your phone.

This data streaming does however use up some of your data allowance.

According to our own tests which we performed using two different internet connections: one in Australia with an average speed of 50Mbps & the other in Vietnam with an average speed of 50Mbps (although this was often slower), the EufyCam 2 can use up to 1.5GB per month in data allowance when used with live-view enabled at all times during work hours (9:00am – 5:00pm).

Considering that most people likely don’t have live view enabled 24/7 we expect actual usage on average, per camera should be much lower than this.

Can You Stop Eufy From Interfering With Your Wi-Fi?

Fortunately, you can change the Eufy’s channel to another one that your router isn’t using and avoid any interference altogether. To do this, go to the app and tap on ‘Settings.’ Then select ‘Wi-Fi Setup’ and finally choose a different channel (1-11).

However, if you can change the channel on your router in addition to changing the Wi-Fi channels on your Eufy, then I would recommend that you experiment with different Wi-Fi channels for both of these devices.

The goal is to find a combination where they are not interfering with each other.


Research would never have been done on Wi-Fi systems if it weren’t for the users who drop in and ask questions like yours.

While my research showed no degradation of a Wi-Fi connection where I own an Eufy router, as one of their customer’s you might be seeing symptoms that I am not encountering.
