If your Dreame base station doesn’t empty the robot’s dust box when it docks, these are the checks from Dreame’s manuals.

What This Problem Means

When the robot docks after a clean, the base station empties its dust box into a disposable dust bag. Dreame’s manuals say this won’t happen if the bag is full, the auto-empty vents are blocked or auto-empty is turned off in the app.

Common Symptoms

• The robot docks but the base station doesn’t empty its dust box
• The dust box is still full after docking
• The D20 Pro Plus returns to the base station without emptying

Safe Checks You Can Try

1. Check the dust bag

Dreame’s manuals say to check whether the dust bag is full. To change it, remove the dust tank cover and take out the old bag; Dreame says pulling the bag’s handle seals it so dust doesn’t fall out: pull it upwards on most models, and outwards on the D20 Pro Plus. Wipe any dust off the filter with a dry cloth, fit a new bag and refit the cover. On the Matrix10 Ultra and Matrix10 Pro, open the base station door first and close it afterwards.

2. Clear the auto-empty vents

If the bag isn’t full, check the auto-empty vents on the robot, the base station and the dust box for anything blocking them, and clear it. Dreame’s maintenance tables say to clean the vents once a month with a soft, dry cloth.

3. Check auto-empty is on in the app

Every manual except the D20 Pro Plus’s says the base station won’t empty the dust box if auto-empty is turned off in the Dreamehome app, and that it empties according to the app setting.

4. Check Do Not Disturb (D20 Pro Plus)

The D20 Pro Plus manual says Do Not Disturb mode stops the robot doing auto-empty tasks. Do Not Disturb is off by default; once it is on, its default period is 22:00 to 08:00, and you can change it in the app.

5. Clean the dust box and filter

Take out the dust box, remove the filter, empty the dust box and gently tap the filter to knock the dirt out. Dreame says to rinse the dust box and filter with clean water only, without detergent, and to let them dry completely before you refit them.

Dust bags by model

Dreame UK quotes up to 100 days between bag changes for most of these models, up to 60 days for the L10s Ultra Gen 2, and up to 150 days for the D20 Pro Plus’s 5L bag. Dreame’s manuals say the real interval depends on how you use the robot.
