What's it doing?
Won't turn on, or the light is blinking
- Plug the power supply straight into a working outlet — no power strip or extension cord — press the power button once and give it 30 seconds.
- Check the cable is clicked fully into the power supply and the plug is dry.
- Lift the robot out, clean the filters and check the impeller under the top cover for a wedged leaf or pebble — a blocked impeller stops the motor and the light blinks.
- Unplug for 30 seconds, plug back in and start again.
Won't climb the walls
- Clean the filters first — clogged filters cut the suction that holds the robot to the wall.
- Let it sink completely before you start: tip it in at an angle and let the air bubble out.
- Check the brushes aren't worn smooth or jammed, and that both tracks turn freely.
- Very slick walls — new tile, a film of algae, heavy chemical treatment — are hard for any robot. Brush the walls once and run it again.
Not moving, or stuck in one spot
- Switch it off, pull the robot out and lay the cable out straight — a twisted cable holds it back.
- Clear the tracks, the brushes and the intake underneath of debris.
- Check it sank fully; air inside makes it hover and spin.
- Look for what it may be catching on: a main-drain cover, a ladder, steps or a light niche.
The cable keeps tangling
- Put only the cable you need in the water; coil the rest on the deck, away from the edge.
- Lay the cable out straight in the sun for an hour so it loses its memory, then start the robot from the same spot each time.
- Make sure the swivel turns freely and the cable isn't knotted at the power supply.
- Take the robot out between cycles — a week in the water is how knots start.
Leaves debris behind
- Rinse the filters after every cycle — fine debris packs them faster than you'd think.
- Use the right filter: fine for everyday dirt, ultra-fine for dust and pollen.
- Run a full cycle, not a short one, and check the brushes and the intake flap move freely.
- Heavy leaf fall? Empty the basket or bag part way through.
Floats, won't sink
- Air is trapped inside: lower it in at an angle and hold it under until the bubbles stop.
- Let it settle on the floor before you press start.
- Make sure the filter cover is latched shut.
App or Wi-Fi won't connect
- The power supply needs a 2.4 GHz Wi-Fi network within range — 5 GHz-only networks won't pair.
- Turn Bluetooth on and stand next to the power supply for the first pairing.
- Power the supply off and on, close and reopen the app, and check for an app update.
- Still nothing? Forget the robot in the app and pair it again from scratch.
Stops early, or shows an error
- Clean the filters and check the impeller — a blockage ends the cycle early.
- Check the cable connection and the outlet (a tripped GFCI looks like a dead robot).
- Unplug for 30 seconds and run it again. If it repeats, note the light pattern on the power supply before you ask us.
Was it like this out of the box? Tell us the order number and the symptom and we'll swap it straight away.
Setup & first run
- Put the power supply on the deck at least 10 ft from the water, in the shade if you can, and plug it into a GFCI outlet.
- Unroll the cable completely and lay it straight.
- Lower the robot in at an angle, let the air bubble out, and let it settle on the floor.
- Press start. Leave it to finish the cycle, then lift it out by the cable (never by the robot alone) and rinse the filters.
