Dyson Micro 1.5kg Seal or Gasket

Instructions
How to complete this repair
- Bright flashlight
- Clean lint-free cloth
- Soft dry brush
- Power the vacuum off, disconnect its charger, and remove a detachable battery only when the exact owner guide describes that action.
- Use only owner-access points and maintenance actions documented for the exact machine code.
- Do not glue, grease, stretch, or substitute an O-ring or gasket unless the exact manufacturer procedure specifies that material and action.
- Do not open the cyclone pack, motor body, powered head, battery, robot drive, pump, or dock to search for an internal seal.
Confirm the Micro 1.5kg configuration
Micro 1.5kg (SV21) is a bagless cordless body with a wand and powered cleaner head fitted to this machine. Cataloged variants include Micro 1.5kg, Micro 1.5kg Gold, Micro Fluffy. The verified owner-service profile identifies it as the Dyson Micro 1.5kg lightweight hard-floor cordless platform. Match the machine code and serial label before ordering a filter, bin, wand, cleaner head, battery, or charger; a retail family name can cover incompatible hardware.
Clean each documented sealing surface
Remove the clear bin and cyclone inlet, filter covers, detachable air-path joints, and owner-removable tanks that this platform actually has. Wipe dust or grit from visible seals and mating faces without pulling a bonded gasket out of its channel.
Inspect for a confirmed defect
Look for a rolled lip, cut, flat spot, permanent distortion, missing section, cracked cuff, warped cover, or latch that cannot compress the seal evenly. A clog can mimic a leak, so confirm the airway is clear too.
Reseat or replace only a listed owner part
Reseat a displaced removable seal exactly as shown in the guide, or replace the complete listed bin, filter cover, wand duct, or cleaner head when its seal is not separately serviced. Match the machine code.
Test for restored performance
Refit every dry part until it latches flush and make one short test. Continued air leakage, dust escape, or liquid leakage from an internal joint requires professional service.
