The revolutionary Pool Blaster CX-1 by Water Tech is an advanced robotic swimming pool cleaner that scrubs, vacuums, and deep-cleans all pool surfaces - floors, walls, coves and even the waterline! The Pool Blaster CX-1 intelligently cleans your pool without limitations. Thanks to its high-capacity lithium powered battery, it is able to clean residential pools of virtually all sizes, shapes, and materials without the hassle of cord tangles. This automated self-driven robotic cleaner is hassle-free and does not require any cables, hoses, or additional pump equipment.

The Pool Blaster CX-1 can clean most typical residential swimming pools in about one hour! The Pool Blaster CX-1 determines a unique cleaning path to ensure that the entire pool gets scrubbed and vacuumed to remove sand, algae, leaves, dirt, and debris. The Pool Blaster CX-1 features quad scrubbing brushes and a wide 18" cleaning track, and has controls that allow two programmable cleaning cycles (runs everyday on "weekly" mode, or provides immediate heavy cleaning on "1-day" mode) and two cleaning modes (comprehensive "floor and walls" or "floor-only").

The fully rechargeable Li-Ion battery cleans the entire week on a single charge. The CX1 battery has a run time of up to 4 hours on a daily charge or up to 30 minutes a day for 7 days.

    Water Tech Smart Features:
  • Cleaning Path: The Water Tech Pool Blaster CX-1 has a program to sets a unique cleaning path that allows it to fit any residential size, shape, and style of swimming pool.
  • Out of Water: The Water Tech Pool Blaster CX-1 is able to drive itself into the water! During cleaning, the CX-1 is able to detect if its path takes it out of water. Should it detect being out of the water, it can then drive itself back into the water; this is especially useful for beach-entry pools or pools with entry steps. If the CX-1 is out of the swimming pool for too long, it is able to shut itself down to save energy.
  • Upside-Down:The Water Tech Pool Blaster CX-1 is able to detect if it becomes oriented upside-down, and can then reorient itself in order to continue cleaning.

Coolest Robot on the planet
Make sure the charging port is securely covered with the rubber seal, then set it an forget it. The robot rolls into the pool on its own. If it flips upside down, no worries! It can flip itself back over. This is not a helpless turtle on the bottom of the pool. This dude even climbs the walls of the pool giving them a scrub as it goes. This expensive purchase has made pool maintenance a breeze. Hopefully it lasts for many years stretching the cost over time. I am enjoying using the pool more and cleaning it less.

The absolute best customer service
I needed a Robot with no cord and an independent filter system. The description on the website looked like this model was a good match for my needs. My robot arrived timely, but was not charging up after one usage. I contacted Water Tech's Customer service and they provided a free return label. Upon receipt of the machine, they immediately sent out a replacement, which I had the following time to charge up and have the pool clean for Father's Day. They were awesome....the absolute best customer service!

Best pool vacuum ever
It keeps my pool clean and keeps lots of dirt from getting into filter. I would buy this product 100 times over. This product is excellent for winter months in Florida when the water is to cold to get into the pool to clean!

It is truly awesome. I've never had to clean my pool again. I charge it weekly and let it drive itself into the pool. Every pool should have one

Asked by: Dan - 2/16/2023
A: The manufacturer rates the battery lifespan not in years (since everyone will use it differently) but in terms of operational cycles which they estimate at 500. As of 2022 the battery replacement was $359 if it needed to be done outside of the warranty.
