Tank series robots are fit for nearly all pool surfaces, including Pebble, Plaster, Concrete, Paint, Tiles, Gunite, Vinyl Liner, PvC and etc.

Always close the charging port cap before using the Tank series robots. It can effectively prevent chemicals and water in the swimming pool from oxidizing the charging port.After finishing using the robots, please rinse the filter basket. Make sure both the charging port and charger are dry before charging.

We have tested in a large number of underwater real-world scenarios, the Tank series robots can easily pass a variety of common drain covers.

The robot will keep cleaning the pool until the battery is low and then stop at the side of the pool.

Tank series are not restricted by the slopes/inclined walls.

The recommended environment temperature for charging is 6-35°C.Do not charge your robot in unfavorable temperatures, e.g. in heat exposure.

Tank series robots can effectively remove debris, including leaves, insects, hair, sand, and other particles which are as small as 180micrometers (μm).

Temperature: 43-95℉

Chlorine: 4 ppm max.

pH： 7.0 - 8.8

NaCl: 5000 ppm max.

We don't recommend to use Tank series robots in a beach entry pool.

1.After daily usea. Clean the product and the filter basket after each cleaning cycle. (Note: Do not let the filter panels dry out before cleaning.)b. Keep it away from strong and direct sunlight.

2.Every 3-4 months or after a deep cleaning cycle when the pool is considered dirtyCheck and make sure no debris is stuck in the impeller, track treads and cogs.

3.Every 12 months or when it is found working/turning slowlyCheck track treads and brush rollers for wear. Replace them when signs of wear are observed.

If the cleaner will not be in use for an extended period of time, perform the following storage steps:

1.Thoroughly clean and dry the filter basket, brush rollers, track treads and cogs.

2.Make sure that no water is left in the cleaner.

3.The cleaner must be fully charged before storing. It should be placed in a well-ventilated and shaded location, at a temperature between 5°-45°c/41°-113°F, and humidity lower than 80%RH.

4.Charge the battery at least once every 3 months to protect it from over discharging.

5.Keep the cleaner out of the reach of children or persons with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction.

When charging, the number of green lights will increase from 1 to 11, and the outermost two lights will flash until fully charged. When all 11 lights turn green, charging is complete. All lights will turn off after 10 mins.

When two red lights appear on the side of the LED bar may be related to overheating protection mechanism. In this case please unplug the charger, leave it cool down for 1 hour then continue charging. Make sure the robot is charged indoors at a temperature between 41-113°F.

Step 1: Check there is voltage in the power socket in the wall,

Step 2: Check if the charging adapter shows green LED when disconnected from cleaner. If not, the charger needs to be replaced,

Step 3: Dry the charging port and retry,

Step 4: If none of these works, the robot may some issues, you can contact our after-sales team through support@smorobot.com.

When the robot is powered on, a cleaning mode is selected simultaneously. Then it will run a default light sequence for self-checkup. When you can see the two flashing yellow lights, it means the robot is ready to be placed into the pool.When the two outer function indicator lights are blue, and the two inner ones are flashing yellow, the cleaner should be submerged in the pool as soon as possible. Or it is going to shut down soon.

The most common reason for this situation is related to placing the product on an inclined surface. Please power it off and reboot. Remember to start the robot on a level ground, not on any inclines.

It means “Initialization Failure”. It could be resulted by error detected in self-checkup or defect in circuited board. Turn off the cleaner, place it on a level ground and then restart it.

The green lights in the middles show the product battery level. White lights at the end indicate the robot’s moving direction like cars. Red lights means there's something wrong with the robot.

Advance/reverse: Two white lights on both sides

Left turn：Two white lights on left side

Right turn：Two white lights on right side

Left motor is stuck: Robot stops and left function lights flash red.

Right motor is stuck: Robot stops and right function lights flash red.

Both left and right motors are stuck: Robot stops and all function lights flash red at the same time.

Pump motor is stuck: Robot stops and function lights flash red in turns.

Solution(for all above lights):

Step 1: Take the robot out of pool, turn it off (important!). Turn the left/right/both track(s) manually to see if it turns. If they turn freely but won’t move underwater, it could be caused by a clogged filter basket or stucked motor. Clean the filter basket and remove the debris in the motor.

Step 2: If the jammed side is more difficult to turn, or the jammed side won’t turn at all, check obstacles in the track (refer to After-sales Repair Manual on How to Remove Side Panels). Blockage could be caused by a stone, a loose screw, the metal rod in brush rollers falling out, etc.

Step 3: If no debris is found in the track, and the tread is still jammed. It could be water ingress in the sealed cabin damaging the walking motors causing the problem. In this case, the sealed cabin needs to be replaced.

The LED light stripe and cover are separate. The water or vapor you see is actually between these two parts. So it's a normal phenomenon.

It’s also caused by blockage in the movement system.

Step 1: Take the robot out of pool, turn it off (important!). Turn the left/right/both track(s) manually to see if it turns. If they turn freely but won’t move underwater, it could be caused by a clogged filter basket or stucked motor. Clean the filter basket and remove the debris in the motor.

Step 2: If the jammed side is more difficult to turn, or the jammed side won’t turn at all, check obstacles in the track (refer to After-sales Repair Manual on How to Remove Side Panels). Blockage could be caused by a stone, a loose screw, the metal rod in brush rollers falling out, etc.

Step 3: If no debris is found in the track, and the tread is still jammed. It could be water ingress in the sealed cabin damaging the walking motors causing the problem. In this case, the sealed cabin needs to be replaced.

Pool drains can have very different diameters, heights, widths, etc. The robot can clean drains whose diameter is≤1.7 inches with no problem.

For those that don’t fall in this scope, you can still try turning off the pool pump to prevent the robot from being stuck by it.

1.Wrong Mode: Make sure the robot is not in Floor-only cleaning mode;

2.Low Power Level: Fully charge the robot, until you can see that all 7 green lights are on;

3.Dirty Filter Basket: Remove the filter basket and clean it with water. If your filter basket has 2 layer, please emove the inner layer of filter basket in order to obtain greater suction power, so that the machine can climb the wall;

4.Unbalanced Chemical Level: If your swimming pool has not been used for a long time and is covered in algae or becomes very slippery. Please clean it with a brush or apply chemical substances to balance the water quality;

5.Different materials can also have an impact on climbing walls, especially those made of slippery materials such as ceramics and glass. In this situation, the bottom and walls of the pool are too slippery for the machine to obtain sufficient friction to climb the wall.

If the robot passes debris but doesn’t pick it up, usually it reflects lack or no suction power.

Solution:

Step 1: Make sure the battery level is not too low. You can tell it by the number of green lights in the middle. One green light or a red light in the center means it needs to be charged.

Step 2: Check if the filter basket is clogged. Change a new one if necessary.

Step 3: Check if the impeller at the top spins. You can tell if it creates waves on the water surface. If not, take out the robot, turn it off. Check for debris in the impellers.

Step 4: If no debris is found in impeller, try spinning it with a tool to see if it can’t be turned. If yes, in this case, it’s water leaking in the sealed cabin damaging the pump motor. The entire sealed cabin needs to be replaced.

Step 5: If the impeller spins but no debris is found, try charging it and use it with a new filter. If the problem persists, change the sealed cabin.

It doesn’t happen often but in some cases it could appear. It could be caused by curved edges of the pool, or repeat the diagonal route in rectangular pools.

Solution:

Step 1: Take it out and restart. Try placing the robot into the pool from a different location. Less likely to solve the problem in pools with curved edges.

Step 2: Always check with Smorobot (support@smorobot.com) for newer software versions that have made improvements.

Scenario 1: Stairs & Sundeck

Check the product models. Tank Series won’t clean Stairs & Sundeck. Currently only some of the Valor models clean stairs and sundecks. Note the minimum water depth required for the robot is 50cm. Even the models that are programmed to clean stairs and sundecks won’t work in water less than 50cm.

Scenario 2: Shallow end

Step 1: Check if water is less than 50cm,

Step 2: There are tapered inclines on the floor in the area. First make sure the battery is not too low. If it doesn’t apply, check with Smorobot (support@smorobot.com) for software update,

Step 3: The robot can’t leave the deep end. Every time it reaches the transitional slope, it returns to the deep end. Check with Smorobot (support@smorobot.com) for software update.

Scenario 3: Slope

Step 1: Check if the pool has steep slopes and inclined walls

Step 2: Check the battery level. Make sure the battery is not too low. If it If it doesn’t apply, check with Smorobot (support@smorobot.com) for software update.

Scenario 4: Deep end (e.g. with diamond point)

Deep end consists of a bottom and gradual slopes connecting the walls, or a bottom with vertical walls. If the robot doesn’t clean the vertical wall, refer to troubleshooting for “the robot doesn’t climb walls”; if the robot doesn’t clean the slope, refer to the Scenario 3 under this question; it’s unlikely if the robot doesn’t clean the bottom in the deep end.

Scenario 5: Single safety ledge & double safety ledge

We have some customers who have pools with different levels of safety ledges. The current software program enables the robots to clean single safety ledge with no problem, but the feature may need to be turned on currently through a cable, but will be through an APP.

The robot will have a problem in the pool with double safety-ledge. It will reach the upper ledge then go back, leaving the areas above the top ledge uncleaned. Currently we have no software solution to this, but please always check with us for newer version (if any).
