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.

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."

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"

Check and clean the machine

A grating or grinding noise could be caused by a blockage.

To always get the best performance from your Dyson purifying humidifying fan, it's important to regularly clean it and check for blockages.

Cleaning your machine

Wipe the machine with a damp lint-free cloth, paying special attention to the two oscillating channels within the amplifier loop.

Look for blockages in the air inlet holes in the shrouds, the small aperture inside the amplifier loop, and the soft plastic mesh visible inside the machine when the evaporator is removed.

Use a soft brush to remove dust and debris.

Do not use detergents or polishes to clean the machine.

Paper in the clear bin

This will indicate that the machine is working correctly.

Like our other cordless vacuums, this machine is engineered for quick clean-ups on hard floors and carpeting, as well as for furniture, stairs and inside the car.

Trickling or gurgling noise

If your machine is making a trickling or a gurgling sound, this indicates that the evaporator may be missing or has not been inserted correctly. Remove the evaporator and reinsert it.

Hold the evaporator by the handle and push it into the machine until it slots into place.

With the evaporator in place, close the inner door making sure it clicks firmly shut.

A trickling or gurgling noise can be heard if the evaporator is missing. In this instance, please replace the evaporator in the machine.

Should the drip tray overfill, the machine's water return float is activated. As the water returns to the tank, a trickling or gurgling noise may be heard. The display screen will prompt that a deep clean cycle is to be run.

Deep cleaning your machine

To always get the best performance from your Dyson purifying humidifying fan, it is important to carry out regular deep cleaning to remove any limescale.

Before and after long periods where humidification is not used, we recommend you run an additional Deep clean cycle.

In hard water areas, you may need to run the Deep clean cycle more frequently. We recommend you use filtered water to always get the best performance from your machine.
