Aquabot X4 robotic pool cleaner Review

Aquabot 4x  review by the pool

Owning a pool feel great. A private pool on your property is a wonderful place to relax and unwind the stress of the day, have fun with the family or enjoy a reflecting time alone.

However, pools are notorious for collecting all forms of dirt and debris from the environment, they have a weird ability to draw in dirt particles and therefore need complete cleaning several times a week, this dreadful work often mars the thrill that comes with having a private pool. 

Luckily there are robotic pool cleaners to do the dirty and strenuous work of pool cleaning and maintenance while you enjoy a dirt-free pool whenever you desire. These gadgets are great at automating pool cleaning, making them simply indispensable for every home with a swimming pool. 

Specially designed for large in-ground pools, Aquabot X4 is a good option for a budget pool robot. It’s equipped with the core features that make automating pool cleaning possible and will get every last piece of grime and dirt off your pool, leaving your pool water shiny and dirt-free. 

The X4 isn’t only for in-ground pools, it’s a versatile pool bot and also works great for above-ground pools and it cleans up fine.

As a low to mid-range pool robot, it lacks most high-end features of premium robotic pool cleaners like programmable weekly timer and Wi-Fi connectivity, but this has no bearing on its performance and the budget price tag justly corresponds to what you get. 

In terms of price, the Aquabot X4 falls below the top robotic pool cleaners such as the Dolphin Premier or Sigma, that cost over $1000 and but more than the cheap above-ground cleaners like the Aquabot Pool Rover Jr, one of our preferred above ground pool cleaners.

How the Aquabot X4 works

This Aquabot pool robot comes with all the basic design features to automate cleaning large in-ground pools of up to 50 ft long. It integrates a powerful motor with rotating scrubbing brush and superior filtering capabilities, with these core features the X4 is able to achieve this fit. 

When it takes on a pool, the rotating micro-brush, with spike-like bristles and driven by a powerful motor, agitates the pool surfaces to dislodge dirt and grime including algae, bacteria, and other pool contaminants. As these dirt come off, the internal pump simultaneously circulates about 85 gallons of pool water per minute through a built-in filtration system. 

An extra-powerful motor drives this pump, sending in debris-filled water and flushing out crystal clear water with enough speed and power to filter up to 10,000 gallons of pool water with 2 hours theoretically. 

The filtration system of this robot comprises dual ultra-fine mesh filter baskets with the collective ability to hold up to 190 cubic inches of debris, dirt and pool rubbish. These filter baskets are made of white cloth-like materials and can capture even the tiniest pool contaminant, as small as 2 micron nominal, including algae and bacteria.

Aquabot X4 has a 4-wheel drive system with high-grip wheels for excellent traction on slippery pool surfaces, including tiles. The sticky foam-like rubber wheels enable the robot to drive over the pool surfaces without leaving streaks or track marks. 

This pool cleaning machine also features the AutoX Pool mapping technology for sizing up the pool, mapping out and using the shortest and fastest cleaning route for efficient and timed cleaning. For smooth and uninterrupted cleaning, the X4 features a floating 60 ft power cord connected to a 360-degree rotating swivel. 

The anti-tangle technology ensures the cord never tangles so the robot can make smooth turns throughout the cleaning. The pool robot lets your program it via an intuitive control panel for automated daily pool cleaning.

The X4 does a good of automatically cleaning both in-ground and above ground pools, it cleans both the floors and walls up to the waterline. This robot has an excellent grip on all types of pool floor, it can rotate through 90 degrees without slipping and it travels steadily along the pool wall, thanks to the rubber wheels. 

As it makes these turns, the power cord never tangles, thanks to the swivel technology, this robot also does not get stuck on pool drains and the filters do a great job in getting almost every visible dirt off your pool, especially leaves, stick, twigs and floating dirt. 

Despite the great features for automated pool cleaning, the X4 does have a few flaws. First, it scrubs pool surfaces with a single rotating micro-brush which is positioned at the center of the robot. The location of this brush doesn’t allow the robot to scrub corners and edges of pool, this is serious disadvantage and you’ll have to use a pool brush to get the corners and edges which the robot missed. 

Alternatively, you use the pool brush to sweep out the corners of your pool before or while the robot is working so that it can pick the dirt from those areas. The X4 can clean pool steps but it doesn’t handle them well enough, now this is general flaw for many robotic pool cleaners, and you will have to occasionally brush your pool steps.

Ease of set-up and use

Like most other robotic pool cleaners, the X4 doesn’t require any form of set-up before you can get it to clean your pool. It comes as a completely packaged gadget and works right out of the box. 

To get started with it, unpack your X4, connect the cable from the robot to one end of the control unit, then plug in the cable on the control unit to the power supply outlet closest to your pool. Place the robot in your pool, switch on the GFCI power outlet and press the ON button on the control unit. It’s very simple and straightforward.

The control unit has a control panel with 4 buttons, 1 power button and 3 buttons for setting your preferred cleaning mode. You can either chose the 1 hour, 1.5 hours or 2 hours cleaning setting, depending on how dirty your pool is and how long you want the robot to clean. 

The X4 also has a “Dirty Filter Indicator” light on the control unit. This light comes on when the filter baskets in the robot are full and need to be cleaned, when this happens the robot will pause and stop working while you take it out of the pool, unload the filters and wash with a stream of water from a hose. 

Taking this robot out of the pool is a bit of a challenge because it weighs 35 pounds which is a lot, it also automatically drains pool water as you lift it from the pool. Aquabot X4 comes with a pool caddy which is great for mobility and stowing away the robot after use.

Aquabot 4x includes a helpful caddy


The Aquabot X4 is a finely designed but poorly constructed robot. It works excellently well as an automatic pool cleaner but the problem comes with the build quality. Despite its 3 year warranty, it’s not sturdily built and probably won’t last that long. 

The X4 is prone to frequent breakdown even after a season of use. The foams on the wheels deteriorate really quick, the wheels get worn with very little use and need replacement really quick, and  the motor also falls apart before long. 

Also, the filter baskets are made of very thin plastic which is far from durable plus the lids on these baskets have the annoying tendency to spontaneously pop open once you remove the filters, spilling its gross contains all over the place. The robot does an excellent cleaning but it isn’t very well-built.

Ongoing maintenance

Maintaining the X4 only requires that you clean out the filters and promptly replace worn out parts. Unfortunately, cleaning out these very fine micro-filter baskets of this robot can be a frustrating task. These baskets have some nooks and crannies where gross pool contaminants get wedged and getting them out is no easy task. 

To successfully do this requires a lot of patience and extreme care, flushing these baskets with high-speed running water may cause a tear and possibly damage the filters. These filters are super fine with white cloth-like materials, and they are able to capture all forms of pool dirt, but cleaning them is an arduous task and you really have to handle them with extreme care. 

Extra purchases and ongoing costs

Aquabot X4 comes as a complete robot plus it comes with a pool caddy so you don’t have to worry about that. And no extra purchases before you can get started with it. However, you may need to get replacement parts even in your first season of using the robot. 

Parts like wheels, drive motor, filter baskets wear out pretty quickly and replacing them can cost you several hundreds of dollars. This robot also comes with a 3-year warranty, but there has been complaints about poor customer service and terribly slow and delayed responses.


  1. How the Aquabot X4 powered?

    The X4 comes with a control unit which has a very long cord that plugs into a GFCI wall socket. The control unit has a 4-button control panel from where you will power the robot and select your preferred cleaning setting. There is also a “Dirty Filter Indicator” on the control panel which comes on when the filter baskets are full and ready to be emptied. When this light comes on, the robot stops working until the filters are emptied, cleaned and replaced.  

  2. My Aquabot X4 tends to stay in the deep end of my pool, how do I get it to clean the shallow end? 

    It takes awhile for this robot to completely learn and master a pool. First, it may be unable to travel to all the shallow ends of the pool on its own. According to the users’ manual, you should start the X4 on different ends of the pool when you first use it, this way it will “learn” the pool layout faster and “know” where to go. Also start the unit in a different place every time it cleans the pool. You can also help your X4 by moving it around the pool a bit using a skimmer pole.

  3. Where do you buy your replacement parts?

    Replacement parts for Aquabot X4 can be gotten from the manufacturer. To get new parts for your X4, you would have to contact them directly with information about your robot. 

  4. Is this robot ready to go right out of the box or does it require setting up?

    Aquabot X4 works right out of the box and does not require any putting together. Simply connect the cables to the right places, place the robot in your pool and press the power button and the robot runs. It’s that simple.

  5. Can you leave this in a saltwater pool or do you need to remove it after each cleaning?

    You can leave your X4 in your pool, but do not leave it for too long at a time in a saltwater pool because the saltwater may damage some of the parts. For saltwater pools, it’s best to always stow away the robot in the caddy after each cleaning cycle.

  6. Does it pick up small particles like sand?

    The X4 does a great job at picking both small and large debris, but it doesn’t always get all the sand out. 

  7. Does the Aquabot X4 climb walls to waterline?

    Yes, it climbs walls and cleans up to a few inches past the waterline before going back down to continue cleaning. 

Final thoughts on the Aquabot X4

If you want a budget pool cleaner to maintain your in-ground pool, the Aquabot X4 is a great option. The Aquabot X4 costs much less than most high-end robotic pool cleaners and offers as much good cleaning as premium pool robots. 

While this robot may seem like a great and an excellent pool cleaner, you should be aware that it is prone to break downs and may not serve you for very long, even in spite of the 3 years warranty. 

If you’d like something of a better build quality, consider other options like the Dolphin Advantage (for 33 ft in-ground pools) or Aquabot Breeze IQ (for 50 ft in-ground/above-ground pools).
