Enabling the Dyson skill
Using the Alexa App on your mobile device or the Amazon website, search for "Dyson Skill". Once it appears, select the Dyson Skill and enable it.
You will be prompted to log in to your Dyson account. You should use the account you connected your machine with via the Dyson Link app.
Once you have logged in, follow the on-screen instructions to link Alexa to your Dyson machines.
How does Alexa identify my machine?
Alexa identifies Dyson machines using their room name. The room name is set when you first connect your machine with the Dyson Link app and can be changed using the Link app as well. A list of preset room names are available in the Dyson Link app, such as 'Bedroom' or 'Kitchen'.
For convenience, you can also rename your machine using the Alexa app. However, this does not affect the room name in the Dyson Link app or how you control your machine with voice commands.
To control a specific Dyson machine using voice commands, you can either directly name the machine in your first command or wait for Alexa to ask which machine you are referring to.
If you ask "Alexa, enable auto mode on Bedroom.", Alexa will identify the 'Bedroom' machine and enable the auto mode for it.
If you ask "Alexa, enable auto mode.", Alexa will ask which machine you want to enable the auto mode for.
Disabling the Dyson Skill
You can disconnect Alexa from your Dyson account and machines by disabling the Dyson skill. You can disable the Dyson Skill using the Alexa app or Amazon website.
Please note that you will need to log in to your Dyson account again if you choose to re-enable the skill.
Please select the appropriate option
Check if Alexa heard you
If Alexa did not respond to your most recent request, what you said may not have been recognised as a question or command. To make sure Alexa recognises your request, speak clearly and ensure you are close enough to your Echo device for her to hear you.
To check if Alexa is able to hear you, ask "Alexa, did you hear me?".
Check your Echo device
If Alexa is still not responding, please check the following:
- Make sure you are using the power adaptor that was included with your Echo device.
- Make sure you have an active internet connection.
- Ensure your Echo device isn't muted. The indicator light will be red when the device is muted.
- Move your Echo device to another location away from walls, speakers and other sources of background noise.
- Unplug your Echo device and plug it back in.
If Alexa is able to hear you, your Echo device should light up with a blue ring after saying "Alexa" to indicate she is listening. If your device has a screen, this will be shown as a blue bar on the display.
Reset your password
If you are unable to log in and link your Dyson account, you may need to reset your password. Select the forgotten password link on the log in screen to be taken through the reset process.
If the password has recently been changed, a 30 minutes period will need to pass before you are able to log back into the Dyson Link app account.
Multiple failures logging into the account (4 or more) will result in the account becoming locked. The account will remain locked for a 30 minute period.
Check for device or setup issues
In order for Alexa to discover your Dyson machine, it must be connected via the Dyson Link app and the Dyson Skill needs to be enabled.
If your machine has not been connected with the Dyson Link app, select the connection journey option to go through these steps.
Your Dyson machine and your Echo device should both be connected to the same Wi-Fi network to allow for discovery.
Check your machine
Turn off your Dyson machine at the wall for 10 seconds. Then turn it back on.
Do the same with your Echo device.
Check that your machine is online by viewing it in the Dyson Link app.
Check the Dyson skill
In the Alexa app on your mobile device, disable and then re-enable the Dyson Skill.
You will need to log into your Dyson account again after re-enabling the the Dyson Skill.
Ask Alexa what she heard
Alexa may have misheard you or misinterpreted something you said as a request. To understand why Alexa just did something, say "Alexa, why did you do that?" or "Alexa, what did you do?".
You can also ask Alexa to read back your most recent request by saying "Alexa, what's the last thing you heard?" or "Alexa, what did you hear?".
You can also view Alexa's activity in the Alexa app on your mobile device. The activity log shows utterances that Alexa heard, responses she gave and actions she took.
Alexa learns the more it is used and is always improving its natural voice recognition. Ease of use will improve over time, however some utterances and commands may need to be in a specific format for Alexa to recognise them.
For example, instead of asking "Alexa, turn on oscillation mode.", try asking "Alexa, turn on oscillation.".
This approach can work with other commands as well. Instead of "Alexa, turn on heating mode.", you can ask "Alexa, turn heat on.".
What are some of the things I can do with Alexa?
There are different kinds of directives that users can use to interact with Alexa. Here are some examples:
Turn settings on and off
- "Alexa, turn on my purifier."
- "Alexa, turn on night mode."
- "Alexa, turn off humidification."
Control number settings
- "Alexa, set the bedroom fan speed to 7."
- "Alexa, turn up the bedroom fan speed."
- "Alexa, decrease the bedroom fan speed by 3."
Changing mode settings
- "Alexa, set oscillation to wide."
Temperature controls (for Dyson heaters)
- "Alexa, make it warmer in here."
- "Alexa, make it cooler in here."
- "Alexa, turn off the heat."

Connect your Dyson machine to your Google Assistant-enabled device
Open the Google Home app and tap the plus icon in the top left. Set up a new device and select "Have something already set up?" Search for "Dyson" and tap to select the Dyson Action.
You'll be prompted to link your Dyson account, this is the one you used to connect your machine to the Dyson Link app.
Follow the instructions in the Google Home app to add your Dyson machines.
How does Google Assistant discover my machine?
When you first connect your Dyson machine to the Dyson Link app you'll give it a room name. You'll find a list of pre-set room names in the app, such as 'Bedroom' or 'Kitchen'. Google Assistant uses this room name to identify your machine.
Google Assistant uses this to name your machine in the Google Home app as well.
How do I control an individual Dyson machine?
To control an individual Dyson machine using voice commands, you can either directly name the machine in your command or say the room name the machine is assigned to in the Google Home app.
If you say "Hey Google, enable auto mode in the Bedroom", Google Assistant will identify the machine named 'Bedroom' or a machine in the bedroom and enable auto mode.
Saying "Hey Google, enable auto mode", will enable auto mode for any purifiers in your current room, if the room is set up in the Google Home app.
Disconnecting your machine from the Google Home app
Open the Google Home app and tap the machine you wish to remove.
Tap the settings icon in the top right and select "Unlink Dyson".
When you remove your Dyson machine from a home:
- It will disconnect the device from members in the home
- It will be unlinked from your Google Account
- Data associated with this device will be deleted. Note: Some basic device data may remain associated with the home.
Check Google Assistant can hear you
Google Assistant may not have heard you or recognised your question or command. Make sure you are close enough to your smart home device and speak clearly.
Check Google Assistant can hear you by asking "Hey Google, what did I just say?". Your smart home device should light up when you say "Hey Google ...". If your device has a screen, you'll see it respond.
Check your smart home device
First, make sure:
- Your Google Nest or Google Home speaker or display is powered on and plugged into a wall outlet
- The microphone isn't muted
- For Google Home: on the back of the device, touch the microphone mute button. Your Assistant will say whether the microphone is muted.
- For Google Nest Mini (2nd gen) and Google Home Mini (1st gen): on the side of the device, toggle the mic switch. Your Assistant will say whether the microphone is muted.
- For Google Nest Audio: on the back of the device, next to the power cord, toggle the mic switch. Your Assistant will say whether the microphone is muted.
- For Google Nest displays: on the back of your display, use the switch to turn on the microphone. Your Assistant will say whether the microphone is muted.
- The LED dots on top of your speaker or display spins or blinks when you say “Ok Google” or "Hey Google."
- If your Assistant answers other questions, try to ask the unanswered question in a different way.
General troubleshooting
If you've checked off all of the steps above and your Assistant still doesn't provide an answer, try one of the steps below and ask your question again. If you still don't get an answer, move to the next step.
Reboot your speaker or display
- Disconnect the power cable from your device.
- Reconnect the power cable.
Make sure your device recognizes the hotword
Say “Hey Google” to your speaker or display. Check if the LED dots on the top of your device spin or blink, indicating that it recognized the hotword.
Make sure your device recognised the question correctly
- Ask your Assistant the question again.
- Say "Hey Google, repeat the question" to make sure your Assistant understood you correctly.
- If it's still not recognizing the question, try to speak slower or try another question.
Resetting your password
If you aren't able to log in to link your Dyson account to the Google Home app, you may need to reset your Dyson account password.
Select the forgotten password link on the log in screen and follow the instructions.
After changing the password on your Dyson account, you'll need to wait 30 minutes before logging back in.
If you enter the password or authentication code incorrectly more than four times, your account will be locked. It will be automatically unlocked after 30 minutes.
Check for device or setup issues
Your machine must be connected to the Dyson Link app and the Dyson Action must be enabled for Google Assistant to discover your machine.
If your machine hasn't been connected to the Dyson Link app, open the app and select Add machine. Follow the in-app connection instructions.
Check your machine
- Unplug your machine and wait for 10 seconds. Plug your machine back in and turn it on.
- Unplug your smart home device and wait for 10 seconds. Plug it back in.
- Open your Dyson Link app and check that your machine is online.
Check the Dyson Action
- Open the Google Home app and check that the Dyson Action is enabled
- Unlink the Dyson Action and then re-link it
What did Google Assistant hear?
Your command may have been misheard or misinterpreted by Google Assistant. To check this say "Hey Google, show me my activity" to bring up your recent activity, including recent voice commands.
You can also ask Google Assistant to read back the last command by asking "Hey Google, what did you hear?"
What actions did Google Assistant take?
Saying "Hey Google, show me my activity" will show you recent voice commands. You can view the details of each command to see what Google Assistant heard, the responses and actions taken.
Google Assistant learns the more you use it but some commands may not be recognised. Try using different words in your command.
For example, if you say "Hey Google, turn on fan motion", and it doesn't work, try saying "Hey Google, turn on oscillation mode".
What are some of the things I can ask Google Assistant?
There are different commands that can be used to interact with Google Assistant, here are some examples:
Turning your Dyson machine on and off
- "Hey Google, turn on my purifier"
- "Hey Google, turn on night mode"
- "Hey Google, turn off humidification on the purifier"
Changing fan speed
- "Hey Google, set the bedroom fan speed to 7"
- "Hey Google, turn up the bedroom fan speed"
- "Hey Google, decrease the bedroom fan speed by 3"
Changing oscillation settings
- "Hey Google, turn on oscillation mode"
- "Hey Google, set oscillation to wide"
Changing temperature settings
- "Hey Google, make it warmer in here"
- "Hey Google, make it cooler in here"
- "Hey Google, turn off the heat"
Controlling your Dyson robot
- "Hey Google, start vacuuming"
- "Hey Google, stop the vacuum"
- "Hey Google, return the vacuum to the dock"

Check base
Check around the base of the machine for any debris or obstructions.
Continuous monitoring
The continuous monitoring option is used for air quality, temperature and humidity data to be relayed to the machine and app at all times, even when you have turned the purifier off. The sensors have small fans that maintain airflow for continuous monitoring, but this should not cause any audible noise interference.
There may be instances when the display shows green, indicating high air quality, but the fan speed is still high. This is due to the machine constantly seeking to maintain a good air quality, and in scenarios such as rooms with leaky windows, the machine must work harder to maintain a good air quality.
This will only happen when the machine is set on auto. To turn off Auto mode, please select Manual mode, either using the remote control or on the app.

Please check the following on the app:
Swipe up to reveal the setting tab and tap to open options.
Swipe down to find the continuous monitoring option and tap to open.
Turn OFF the 'Collect data when in standby' option. (The icon will turn grey when turned off). Save the change by pressing 'Done' at the top right of the page.
Continuous monitoring can now also be turned on/off by pressing the 'Auto' button on the remote control for five seconds.
Retest the machine.
Restart the machine
Unplug the machine and leave it for 10 seconds.
Plug the machine back in and retest.
Check and clean loop amplifier
The following areas should be checked and cleaned to maintain the machine's performance.
Clean the loop amplifier with a dry or damp cloth.
Ensure that the narrow opening is free of obstructions.
Check and clean Main body
Clean the shroud of the Main body with a dry cloth.
Use a soft brush to clear any blockages from the holes.

Remove the filters
Switch off and unplug your machine.

To remove your HEPA+Carbon filter, push down on the buttons either side of your machine to release the outer cover. Push down on the tabs to remove the filter.

With the HEPA+Carbon filter removed, put the outer covers into position on your machine and push firmly until they both click securely into position.

The first time your purifier is turned on, the gas sensors will perform a self-calibration which takes one hour after which time they will work normally.
If the power cuts out within the hour, the initialisation period will continue from where it left off.
How long has your purifier been turned on for?
If your machine is new out of the box and has been turned on for less than one hour, the machine may still be calibrating. This process takes up to one hour to complete. Please leave the machine running during this time.
After one hour, turn the machine off and then on again. Press the power button on either the main body or the remote control.
Factory reset
If your purifier has been plugged into a stable power source for over one hour and the selected readings still do not show, we advise that you perform a factory reset.
Press and hold the power button on both the main body and the remote control.
Continue to hold the buttons until the LCD screen shows a countdown timer.
Once the countdown has been completed, the machine will have reset.
Your purifier will turn on automatically. Leave your machine running for one hour to perform self-calibration.
Note: By resetting the machine, your Wi-Fi network details will have been removed and your purifier will no longer be connected to the Dyson Link app. You will need to restart the connection journey.
Restart the machine
Switch off and unplug the machine.
Ensure all outside doors and windows are closed.
Vacuum the four sensor slots to the left of the LCD screen.

Plug in and test the machine.
Switch off and unplug the machine.
Move the machine to another room.
Plug in and test the machine.
Night mode is not working
When in Night mode, your machine will automatically sense the ambient light level and adjust the resting screen brightness accordingly.
If the room is bright, (for example, the lights are on), the screen's display will be set to minimum brightness. If the room is dark (lights off) the screen is turned off.
In both scenarios, when the machine is interacted with, the screen brightness will uplift.
The display will not stay on my selected screen
The interface is designed to stay on the screen you select. Please ensure the remote is not being accidentally pressed.
My display is reading green but the fan is working at high speed
There may be times when the display is showing green but the fan speed is still high.
This is due to the machine always trying to maintain high air quality. For example, in a room with leaky windows, the machine has to work harder via a higher Fan speed to maintain a high air quality.
If you want the fan to be quieter, you can choose to change the airflow direction to face backwards, or turn the machine to manual mode and lower the airspeed.

My readings are showing in different colours
The colour of the numbers and readings on the display are linked to the air quality of the respective category.
Green denotes a high air quality, with low pollutants, and red, low air quality with a high amount of pollutants.
Different categories can have different levels of pollutants at the same time, and will therefore display in different colours.
