### Upgraded Anti-Slip Wheel for ILife T20S (Uses iRobot Roomba Tires)
This is a functional replacement wheel for the ILife T20S robot vacuum cleaner.
The Problem: The stock plastic wheels often slip on laminate, tile, and other smooth floors, causing the robot to lose traction and fail its cleaning routes.
The Solution: This custom-designed wheel allows you to stretch a standard, high-traction Chinese rubber tire designed for iRobot Roomba (I7 E5 E6 500 600 700 800 900 Series) over it. This completely fixes the slipping issue.

### 🛠 Disassembly & Installation Guide
Follow these steps to successfully install the new wheel:
1. Access the Gears: Disassemble the wheel module housing down to the internal gears by unscrewing the casing.
2. Remove the Gear: Locate the small locking washer (retaining ring) on the wheel axle, situated right above the gear. Note: It might be hidden under the white factory grease. Remove it carefully, then use a flathead screwdriver to gently pry the gear upwards while rotating the wheel.
3. Heat the Axle (Crucial Step): The original plastic wheel will come out of the housing together with its metal axle. The screw holding it is locked with high-strength thread glue. To release it without breaking anything, use a hot air rework station (soldering heat gun) to gently heat the metal axle. Monitor the temperature by touching the screw head with your finger. Once it's hot to the touch, easily unscrew it.
4. Extract the Axle: The heated metal axle will smoothly slide out of the old plastic wheel from the opposite side.
5. Save the Nylon Washer: Pay close attention to the small nylon washer on the axle. Do not lose it. You must transfer it onto the new 3D-printed wheel.
6. Reassembly: Slide the new resin-printed wheel onto the axle, tighten the screw, stretch your iRobot Roomba rubber tire over the wheel, and put everything back together in reverse order.
