SMOROBOT Tank X11 – Robotic Pool Cleaner

There aren’t many pleasures in life that can rival owning a pool. However, having to manually clean it yourself can dampen enjoyment considerably. The X11’s exceptional ability to clean every nook, cranny, and crevice makes pool ownership an unparalleled joy once again.

The SMOROBOT Tank X11  features


  • Electronic brain using advanced algorithms maximizes efficiency;
  • Set-it-and-forget it functionality;
  • Cordless operation means no annoying entanglements;
  • Works on most pool surfaces;
  • Tank-like treads for exceptional maneuverability;
  • Over 210 minutes of run time.

Who’s It For?

If you live on the edge of a desert and lots of fine dust blows your way, you’ll love how this unit slurps it all up before the gunk can turn your formerly delightful backyard swimming hole into an ungodly mess.


It’s perfect for owners who are getting older and no longer have the energy to clean their pools using their own elbow grease. With this unit at your beck and call, you’ll finally be able to retire that outdated manual pool brush.

The X11 not only cleans every inch of your pool from top to bottom but also gets rid of stubborn algae stains with its vigorous scrubbing action. It picks up everything from large leaves to bits of gravel and dead bugs.



Exceptional Performance

Even though we live in an era of stunning technological advances, many robots are still pretty dumb when it comes to carrying out pool cleaning tasks. These inferior machines bump into objects like crazy, get themselves stuck in corners, and are generally ineffective at getting your swimming pool sparkling clean.

There are pool-cleaning droids that take way too long to charge and have a short battery life. Some move aimlessly about, which isn’t the most efficient way to get the job done. Others have weak suction, making it next to impossible to slurp up larger debris. The X11 suffers from none of these shortcomings.

SMOROBOT Tank X11 is ready to clean the pool

That’s because it has an electronic brain that uses advanced algorithms to make its way around your home.No matter how exceptional a pool robot’s cleaning abilities are, without the ability to plan out an efficient cleaning path, a bot won’t systematically clean a pool.

This means that it’ll invariably miss spots, making it more of a high-prized and oversized paperweight than something you can actually use. Because the X11 has plenty of onboard intelligence, it cleans ten times better than pool cleaners that don’t have this kind of technology.

NOTE: The X11 efficiently cleans your pool in a grid-like pattern, ensuring it won’t miss a single spot. Its unique motion-controlled system that allows it to adjust its position in real-time means your pool will be cleaner than ever.

Set-It-And-Forget It Functionality

This small but powerful droid is a set-it-and-forget-it device. Simply turn it on, place it in your pool, and your faithful cleaning companion will go to town on dirt, grime, and muck with little to no intervention on your part. This makes it one of the handiest devices to own if you want to make your life as easy as possible.

Works on Most Pool Surfaces

Some pool-cleaning machines are picky about which type of pool surfaces they’ll clean. This isn’t the case with the X11, as it’s suitable for virtually all of them, including pebble, plaster, concrete, tile, gunite, vinyl, and PVC.

Incredible Suction

SMOROBOT Tank X11 has incredible suction

You won’t have to worry about wimpy suction with the X11 because, with 188 watts of power, it easily picks up even larger debris, such as bits of gravel. This ensures that your pool will be blessedly free from unsightly junk on your pool bottom after the bot finishes a cleaning cycle.

Tank-Like Treads

With the SMOROBOT Tank X11, “tank” is right in the name. That fits it to a “T” because two military vehicle-like treads allow the unit to stick securely to walls and move along your pool bottom without slipping and sliding all over the place.

NOTE: This ensures your droid will thoroughly clean every part of your pool instead of skipping spots because of compromised maneuverability due to an inability to adhere to surfaces. In fact, it’s nimble enough to get into the crevices, corners, and nooks of virtually any pool shape.

Two Filter Baskets

The unit uses two different filter baskets to cover all the sizes of debris in your pool. One is a fine mesh to suck up ultra-fine particles such as sand, and the other is a coarse mesh to capture larger debris such as bugs, leaves, twigs, and gravel.

Effective Roller Brush

Ultra-Scrubbing Brush Wheels To Clean Stains and Grime

The roller brush is split in the middle so it can move independently in two different directions. This gives the cleaner much more flexibility than a machine that doesn’t have this capability. That way, it easily removes stubborn stains, disgusting grime, and unsightly filth. The junk scraped off by the brush is promptly deposited into the filter basket thanks to precise suction port positioning.

Easy Retrieval

The X11 positions itself near the pool wall when its battery is low or after completing a cleaning cycle. This makes it exceedingly easy for you to remove it from the water.

When taking the unit out of the pool, use the included floating ring attached to a rope. Or use the hook that comes with the unit attached to a pole.

Long Run Time

SMOROBOT Tank X11 has 10000mAh battery

You don’t have to worry about charging the X1 every few minutes because you get over 210 minutes of run time per charge provided by an exceptional 10000mAh battery.

24-Month Warranty

The X11 comes with a 24-month warranty that covers manufacturing defects, wear and tear, and damage due to everyday use. If anything goes wrong during that time and you need to replace the unit, simply call the manufacturer.

Lightweight and Compact

Although the X11 isn’t the lightest pool cleaning bot on the market, it’s lightweight and compact enough that it’s easy to carry and place in the pool. That way, you won’t get a hernia from transporting your bot from the storage shed to the pool area.

Easy to Empty and Clean!

Emptying your pool cleaning robot is simple, with a large door on the top opening to a generously sized filter canister. This makes it easy to dump all the dirt and debris your unit collects during a cleaning run. Just toss all this yucky stuff into the trash and use a low-pressure garden hose to rinse the canister.

Fast Cleaning Mode

The X11 has a fast mode which allows you to clean your pool in half the time it takes standard mode to do the job. That way, if you suddenly remember you invited a few friends over to take a dip, you can have your pool clean by the time they get there.

Impressive Clean Rate

The X11 has an impressive clean rate of 1180 square feet per hour. This means that this one’s already done by the time lesser pool-cleaning robots are hitting their stride.

Phenomenal Waterline Scrubbing Capability

The bane of every pool owner’s existence is an unsightly waterline. That’s all the debris that builds up around your pool’s perimeter where the water ends and the tile begins. Calcium deposits, mineral buildup, sunscreen, and body oils contribute to this pervasive problem.

That’s why you might be glad to hear that the X11 has a better waterline scrubbing ability than over 90% of the machines on the market.

Cordless Operation

Most robotic pool cleaners have cords that dangle behind them. However, the X11 is 100% cordless, so you’ll never have to rescue it because it somehow got itself all tangled up.



Some users complain that the X11 beaches itself from time to time on their drain covers. However, this is a problem lots of pool cleaning robots have. Other customers report that their units suddenly lost suction after they used theirs for a month or two. On the other hand, these users were happy that customer service replaced their malfunctioning units.
