Step 2: Check and Clean the Filters
- Remove the pre-filters from the vacuum. For the Dyson V15 Detect, this involves removing the filter from the cyclone assembly as per the manual.
- Rinse the filters under cold water, gently squeezing out dirt. Do not use detergents or brushes that could damage the filter.
- Allow filters to air dry completely, usually 24 hours, before reinstalling.
Step 3: Clear Blockages
Inspect the wand, hose, and cleaner head for any blockages. Detach these parts and look for debris or tangled hair. Use a long, slim tool or the crevice tool to gently dislodge obstructions.
Step 4: Check the Bin and Seal
- Ensure the dustbin is empty and properly seated. Empty it if full.
- Inspect the sealing ring for damage or misalignment. A proper seal maintains suction.
Step 5: Reassemble and Test
After cleaning and inspecting, reassemble the vacuum carefully. Turn it on and test on a small area to verify if suction has improved.
