Vacuum runs but the exhaust air is unusually hot, even on low power.

Safety first: Remove the battery and allow the vacuum to cool before inspection.

• Step 1 – Clean or replace HEPA filter: Remove the HEPA filter and clean or replace it with a genuine Tower HEPA filter cartridge.
• Step 2 – Clear vents: Use a soft brush to remove dust from all motor cooling vents on the main body.
• Step 3 – Check cyclone and bin: Ensure there are no blockages in the cyclone or bin inlet.
• Step 4 – Usage environment: Avoid using the vacuum continuously in very hot rooms; allow cooling breaks.
