The green laser on the Fluffy cleaner head had brightness inconsistencies in direct sunlight. A firmware patch allows the sensor to auto-adjust laser intensity based on ambient light sensors.
Dyson has hinted that the V15 will remain in their "active support" lineup for at least two more years. Rumored upcoming features (potentially arriving via Q4 2025/Q1 2026 firmware) include:
If your V15 still runs on firmware from 2023, you are essentially driving a car with a paper map while a GPS is available. The hardware is capable; the software just hasn't been unlocked yet.
You cannot update the firmware without first knowing what you are running. Here is how to locate your current firmware version:
As of mid-2025, the most common stable firmware versions are between v1.1.1 and v2.0.4. If your version starts with v0.9.x, you are severely behind.
Step 1: Pair your V15 with the MyDyson app If you haven’t already, open the app, tap "Add Product," and scan the 13-digit serial number on your V15's main body (or the QR code inside the bin). dyson v15 firmware update
Step 2: Bring the vacuum close to your phone Firmware updates happen via Bluetooth, which has a short range. Place your phone within 3 feet (1 meter) of the LCD screen on the vacuum.
Step 3: Initiate the connection In the MyDyson app, tap on your V15 device. The app will "wake up" the vacuum. You may need to pull the trigger on the vacuum once to activate the Bluetooth radio.
Step 4: Check for the update The app will automatically compare your current firmware with Dyson’s servers. If an update is available, a banner will appear saying "Firmware Update Available."
Step 5: Start the transfer Tap "Install Update." The app will download the file to your phone, then beam it to the vacuum. Do not leave the app or lock your phone during this stage.
Step 6: Wait for the vacuum to install Once the file is transferred, the V15’s LCD screen will go dark and then display a progress bar (0% to 100%). This can take 5 to 15 minutes. The green laser on the Fluffy cleaner head
Step 7: Automatic reboot The vacuum will shut off and turn back on. Your screen will now show the new firmware version. You are done.

Before we dive into the "how," let's address the "why." The Dyson V15 Detect is not your grandmother’s Hoover. It contains a piezo sensor that counts and measures dust particles, an LCD screen displaying a scientific proof of clean, and an auto-mode that ramps up suction when it detects high debris.
Firmware controls all of this. Here is what a typical firmware update can do:
Ignoring a firmware update means your $700+ vacuum cleaner is running on outdated logic, potentially missing out on efficiency gains or new diagnostic tools.
Many users don’t realize their vacuum runs on firmware. Skipping updates can lead to:
Dyson rarely publishes flashy "feature drop" patch notes, but internal changelogs typically address these core areas.
