Replacement parts for WYBOT pool cleaners

The WYBOT robot components most frequently replaced are the dirt-retention modules and mechanical traction parts.

• RWY3320 filter basket for collecting coarse solids and leaves.
• HEPA filter for micron-level filtration in models such as the E-TRON C20.
• RWY3322 front wheel and RWYM019 axle brackets for wear and tear.
• RWY10NG18 battery and waterproof RWY33NG23 charger for continuous recharging cycles.

Choosing genuine WYBOT pool cleaner replacement parts restores the rated travel speed and prevents mid-cycle stops caused by uneven friction.

Loss of traction on slippery surfaces is caused by wear on the RWY3322 front wheel or play in the RWYM019 bracket.

When friction against the pool floor wears down the outer treads of the wheel, the motor spins without transferring the torque needed, causing the wheels to spin freely. Also check that embedded sand is not building up on the lower fin and preventing the central axle from rotating freely. If the chassis slips sideways, replacing both the wheels and fins restores proper traction during the cleaning cycle.

The technical difference lies in the particle retention level and the density of the filter fabric.

The RWY3320 basket is designed to trap bulky debris such as leaves, pine needles, and insects, allowing a steady flow of water without clogging the impeller. In contrast, the HEPA filter fitted to advanced units such as the E-TRON C20 range captures fine dust, pollen, and mineral sediment down to a few microns. Using the right combination at each time of the season protects the suction turbine and optimizes pool water clarity.

Check the output of the RWY33NG23 charger before replacing the RWY10NG18 battery to isolate the source of the electrical fault.

A multimeter placed on the pins of the watertight charging connector can verify whether the transformer supplies the nominal DC voltage specified by the manufacturer. If the charger outputs the correct voltage but the robot’s LED indicator does not complete charging or switches off after 10 minutes of immersion, the lithium battery cells have reached the end of their life due to chemical degradation. Installing a new battery ensures full cleaning cycles of between 90 and 120 minutes, depending on the selected program.

Chassis compatibility is confirmed by matching the alphanumeric code printed on the machine’s lower serial plate with the replacement part number.

• Find the factory technical label on the underside of the chassis or beneath the basket’s watertight compartment.
• Check whether your device belongs to the Spyder or Osprey families, or the E-TRON C20 series, before ordering rollers or fins.
• Check standardized manufacturer part numbers, such as RWY3322 for wheels or RWY3320 for collection baskets.

Buying components that match the official parts diagram prevents mechanical play and internal water leaks in the motor housing.

The carrying handle on the Spyder Wybot robot is installed using snap-fit clips that require no special tools.

Pulling the robot out by the fin or floating cable puts strain on the housing’s watertight seals, which can cause cracks that let water into the sealed drive unit. The original replacement part fits directly onto the upper guides of the structural chassis. When installing the new handle, make sure you hear the latch click on both sides before submerging the pool cleaner, ensuring a firm, secure lifting point.

Preventive maintenance after each immersion cycle extends the service life of filters, baskets, and plastic drive components.

Rinse the RWY3320 filter basket with low-pressure fresh water to remove salt and chlorine before letting the unit dry in the shade. Inspect the RWY3322 front wheel bearings periodically to remove hair or fine sand that may impede the axle’s free rotation. Also, keep the pins on the watertight charging connector dry before connecting the RWY33NG23 charger, protecting the metal contacts from galvanic corrosion during the 2026 swimming season.
