Niya Tracker 35

Inground and above-ground pools up to 40 ft long. Its 2.5-hour cycle covers the floor, walls and waterline of a pool that size.

The Tracker 55 adds a Bluetooth app for choosing cleaning modes. Coverage, run time, pool size and warranty are the same.

Charge it fully before the first run; the LED turns steady green when it is ready. Unplug the charger, press the power button, and lower the robot into the water near the middle of the pool. It sinks to the floor, starts cleaning on its own and parks at the wall when the cycle ends or the battery runs low. Lift it out, empty and rinse the basket, and put it back on the charger for next time.

Charge it in a shaded, dry spot from a GFCI outlet, with the charger plugged straight into the wall rather than an extension cord and kept at least four feet off the ground. Connect the charger to the robot: the LED glows steady red while charging (some units flash green instead). When the battery is full the LED turns steady green and switches off after ten minutes; unplug the charger from the robot and the outlet. The robot shuts the charger off by itself when it is full to protect the battery.

Almost always a battery that drained during shipping or storage. Put the robot on its charger until the LED turns steady green, then try again. If it still will not start after a full charge, contact us and we will arrange service under the 1.5-year Maytronics warranty.

The robot is stuck. Lift it out of the water, wait for the blue LED to start flashing, then put it back in and it will carry on cleaning. If it keeps getting stuck in the same place, check for a drain cover, a ladder or a steep slope at that spot.

Too much debris in the basket weakens the suction that holds it to the wall. Empty and rinse the basket first. If the filter is clean and it still slips off, clean the impeller as described in the manual, and check that the water chemistry is in range, since a high pH or very cold water hurts climbing on any robot.

A clogged filter is the usual cause: a dirty pool fills the basket fast and the suction drops with it. Turn the robot off, pull the basket, rinse it with a hose and replace the filter if the mesh is damaged. A clean filter restores both speed and suction.

You rarely have to reach for it. When the cycle ends or the battery runs low, the robot parks itself at the pool wall just below the surface. Lift it by the handle or hook it with the Niya retrieval hook on a standard pool pole, let the water drain for a moment, then rinse it and set it aside to charge.

Balanced water and a filter that is not already full. Keep free chlorine at 1 to 3 ppm, pH between 7.2 and 7.6 and the water above 59°F for the best cleaning, and wait 24 hours after a shock or flocculant treatment before the robot goes back in. Saltwater pools are fine. Rinse the robot and basket with tap water after each cycle.

Niya is Maytronics' value line: cordless, light and simple, with one coarse top-load basket, no timer and a 1.5-year warranty. Dolphin robots cost more and add longer warranties, fine and ultra-fine filtration, weekly timers or Wi-Fi apps and more cleaning modes. If your pool collects fine silt or algae, or you want cleaning on a schedule, a Dolphin is the better buy; if you want a dependable cordless cleaner at the lowest price from a manufacturer with a real parts and service network, Niya fits.

Maytronics, through its US service network, under the 1.5-year warranty. Contact Pool Express first: our Pool Pros will confirm the fault, help you order a replacement part if that is all it needs (filters, wheel sets, batteries and chargers are stocked part numbers) or arrange the warranty claim. You also have our 30-day trial from delivery.
