Niya · Troubleshooting guide

Niya Aquasweep S1 troubleshooting.

Start by checking charging if your Niya Aquasweep S1 will not run or stops sooner than expected. Then check the filter and filter lock, or contact Poolbots' pool experts by live chat or phone for help. Every fix below is rewritten in plain English and sorted by what the robot is doing wrong, with the genuine part that fixes it.

Quick checks

The Niya Aquasweep S1 problems we hear about most.

Cleaner will not startCheck the Aquasweep S Charger - US connection and let the battery charge before trying to start the cleaner again.
Weak suctionTurn the cleaner off and check the Aquasweep S1 Filter for collected debris.
Cleaning time seems shortCheck that the battery has charged before use. The listed runtime is up to 2 hours, not a fixed length for every session.
Filter will not stay securedWith the cleaner off, check that the Aquasweep S1 Filter and Aquasweep S1 Filter Lock are seated properly.

Start here

Three checks before you suspect the robot.

Charge, filter, impeller, tracks: in that order. Where a check ends in a worn part, the genuine replacement is linked under it.

  1. Charge fully with the Niya charger

    Use the charger supplied with the robot and charge indoors, out of direct sun.

  2. Clean the filter and impeller

    Rinse the filter after each cycle and check the impeller grill for hair and debris.

  3. Check the tracks or wheels

    Remove anything caught in the tracks; worn tracks are a cheap replacement part.
