The non-WiFi version typically uses a 2-prong connector, while the WiFi-enabled version requires a 3-pin connector. Check your current control box connection port and compare it to the listing specifications. Using the incorrect connector will prevent the unit from powering on and could potentially damage the control box, so always confirm this specific detail before placing your order.

Can I use a cordless cleaner in any pool?

While cordless cleaners offer great versatility, you must verify the unit's maximum pool size and surface compatibility. Some models are optimized for above-ground pools, while others are designed for inground use. Always check the manufacturer's recommended square footage to ensure the battery life and suction power are sufficient for your pool. Additionally, ensure the cleaner is rated for your specific pool surface, such as vinyl, tile, or concrete, to achieve the best cleaning results and prevent potential damage to the pool liner.

Is it safe to leave the robot in the pool?

It is generally recommended to remove the robotic cleaner from the pool after the cleaning cycle is complete. Leaving the unit submerged for extended periods can expose the internal components to pool chemicals, which may accelerate the degradation of seals and plastic parts. Furthermore, constant exposure to water can lead to algae growth on the cleaner itself. Always rinse the unit with fresh water after removal to neutralize any chemical residue and store it in a dry, shaded location to prolong its service life.

How often should I clean the filter canisters?

You should clean the filter canisters after every full cleaning cycle. If your pool has a high debris load, such as after a storm or during autumn, you may need to check the filters more frequently. A clogged filter restricts water flow, which reduces the robot's suction power and puts unnecessary strain on the motor. Regularly rinsing the filter mesh ensures the robot maintains optimal performance and prevents debris from being recirculated back into your pool water.

What should I do if the robot stops climbing walls?

If your robot stops climbing, first check the brushes for wear; if the bristles are flattened, they cannot provide the necessary grip. Next, inspect the tracks for debris or signs of stretching. Ensure the filter is clean, as a heavy, debris-filled filter can make the unit too buoyant or heavy to climb. Finally, check the water chemistry; if the pool has an algae bloom, the surfaces may be too slippery for the robot to maintain traction. If these factors are addressed and the issue persists, consult the manufacturer's support.
