Abstract

A method of dust processing comprises measuring (PC1) a first amount of particles of a first size (e.g. PM10), and measuring (PC2) a second amount of particles of a second size (e.g. PM2.5) smaller than the first size. In accordance with the invention, it is determined (Δ) whether the first amount exceeds the second amount by a predefined threshold. If so, a robotic vacuum cleaner (RVC) may be prompted to start cleaning a room.

Claims

1. A method of dust processing, comprising:

measuring (PC1) a first amount of particles of a first size;

measuring (PC2) a second amount of particles of a second size smaller than the first size; and

determining (Δ

) whether the first amount exceeds the second amount by a predefined threshold.

2. A method as claimed in claim 1, further comprising cleaning a room by means of a robotic vacuum cleaner (RVC) if the first amount exceeds the second amount by the predefined threshold.

3. A method as claimed in claim 1, further comprising informing (D) a user if the first amount exceeds the second amount by the predefined threshold.

4. A method as claimed in claim 1, wherein said second size is smaller than or equal to 5 μ

m.

5. A method as claimed in claim 4, wherein said second size is smaller than or equal to 2.5 μ

m.

6. A method as claimed in claim 1, wherein said first size is smaller than or equal to 200 μ

m.

7. A method as claimed in claim 6, wherein said first size is smaller than or equal to 10 μ

m.

8. A dust processing device for carrying out the method according to claim 1, the dust processing device comprising:

a particle counter (PC1, PC2) for measuring a first amount of particles of a first size, and a second amount of particles of a second size smaller than the first size; and

a control circuit for determining (Δ

) whether the first amount exceeds the second amount by a predefined threshold.

9. A dust processing system comprising:

the dust processing device as claimed in claim 8, the control circuit having an output for providing a control signal indicating whether the first amount exceeds the second amount by the predefined threshold; and

a cleaning apparatus (RVC, AP) having an input for receiving the control signal for starting a cleaning operation in dependence on the control signal.
