Buying Guide

Key Features to Consider

The Smorobot Tank X11 distinguishes itself with a powerful quad-motor system and caterpillar treads, designed to climb vertical walls and navigate complex pool shapes effectively. Buyers should prioritize the extended battery life, offering up to 180 minutes of cleaning per charge, which is essential for larger inground pools. Additionally, the cordless design eliminates tangled hoses, while the top-access filter basket simplifies maintenance, making it a robust choice for automated floor, wall, and waterline cleaning.

Budget Recommendations

As a mid-to-high-tier investment, the Tank X11 offers advanced features typically found in more expensive professional models. If your budget falls within the $800 to $1,100 range, this unit provides excellent value through its superior climbing ability and extended runtime compared to budget-tier competitors. For pool owners seeking a balance between performance and cost, this model is a strong recommendation, though those with very small or simple above-ground pools might find more affordable, basic units sufficient for their needs.

Common Pitfalls to Avoid

A frequent oversight is neglecting pool surface compatibility; while the X11 handles concrete and liners well, extremely smooth fiberglass may require checking for optimal traction. Avoid the mistake of ignoring the filter maintenance schedule—clogged baskets significantly reduce suction and climbing performance. Lastly, ensure the pool is free of large debris like branches before deployment, as the intake is designed for fine particles and leaves, not large solid objects that could cause internal jams.

How We Test

Frequently Asked Questions

What is the battery life and run time of the Smorobot Tank X11?

The Smorobot Tank X11 is equipped with a high-capacity 10,000mAh lithium battery that provides up to 180 minutes of continuous cleaning time on a single charge, making it suitable for large pools.

Does the Tank X11 climb walls and clean the waterline?

Yes, the Tank X11 features powerful dual-drive motors and enhanced climbing abilities, allowing it to scrub pool walls and clean the waterline effectively, in addition to the pool floor.

How does the cleaning navigation system work?

The robot utilizes advanced Smart Navigation 2.0 technology, which includes sensitive water sensors and a triple-motor system to calculate the most efficient cleaning path, avoiding random tangling and ensuring comprehensive coverage.

Is the Smorobot Tank X11 safe to use while swimming?

No, for safety reasons, you should ensure the floating power cord (if used for tethered power supply) is disconnected or ensure the unit is not operating while people are swimming. However, the X11 is primarily a cordless unit, so it should be retrieved and turned off before swimming to avoid contact with the moving brushes.

How do I maintain and clean the filter?

The Tank X11 features a top-load filter basket design. After cleaning, simply unlock the top lid, remove the filter basket, and rinse it with a garden hose to remove debris. The ultra-fine filter plates are designed to capture small particles like sand and leaves.
