The smart APP control allows you to switch modes and customize paths, though you must set it before the robot enters the water.
Build quality appears solid with a rugged Obsidian finish. The cordless design eliminates cord tangling and makes storage easy. However, at 15.9 x 15.7 x 11 inches, the unit is relatively large, so it may not fit in tight spaces. The lack of user reviews means we cannot confirm long-term durability, but the feature set suggests good value for the price.
A potential drawback is the app requirement: you cannot change settings while the robot is submerged, which may be inconvenient if you want to adjust mid-cycle. Additionally, the product is new, so customer support and firmware updates are unproven. For most users, the convenience of cordless operation and wall-climbing will outweigh these minor concerns.
Overall, the Letexpool C1 is a compelling choice for pool owners seeking an automated, cord-free cleaning experience. Its combination of long battery life, multiple modes, and APP control makes daily pool maintenance much easier. If you have a large in-ground pool and want to reduce manual work, this robot is worth considering.

The EZIOOV U8 is a cordless robotic pool cleaner built for owners of medium to large inground pools up to 2,600 square feet. It is designed for anyone who wants automated cleaning of the floor, walls, and waterline without dragging hoses or spending weekends brushing. With a 150-minute runtime, the U8 can handle weekly maintenance in a single charging cycle.
The standout feature is wall and waterline scrubbing. Triple brushless motors and strong traction allow the robot to climb surfaces and remove grime, oil, and stuck-on debris that usually requires hand work. Gyroscope and ultrasonic sensors help it follow efficient paths and avoid obstacles while covering deep ends, corners, and ladder areas.
The 26-pound body feels solid in the pool, and the quick-drain design makes lifting easier after the cycle ends. Its 4-liter top-load filter catches fine dirt, sand, leaves, and larger debris, and you can empty the basket without turning the unit over. The carbon black finish looks clean, and a simple one-button control keeps the experience straightforward.
The main limitations are the lack of remote control or app scheduling and the unit's weight when removed from a deep pool. You choose a mode by pressing the button and let the robot do its work, but there is no way to steer it manually. Since this model has limited customer feedback available, long-term durability is not yet verified by extensive real-world use.
For pool owners who prioritize cordless freedom, wall scrubbing, and a long runtime, the EZIOOV U8 is a strong option. It simplifies routine maintenance and eliminates the tangles and setup of corded units. If you have a larger inground pool and prefer one-button automation, the U8 is worth serious consideration.
What to Look for in a Budget Pool Robot
Battery Life and Coverage Area
Runtime dictates how much of your pool gets cleaned per session. For a typical residential pool, a robot with at least 100 minutes of operation can handle routine maintenance. The Tnbacious model offers 100 minutes, while the Letexpool C1 and CliBot S5 both deliver up to 180 minutes. If you have a larger pool, look for longer endurance to avoid incomplete cycles. The best robotic pool cleaner with 3 hour runtime list covers more options for extended cleaning.
Wall-Climbing and Waterline Scrubbing
Algae and scum buildup on walls and the waterline can turn a quick skim into a scrubbing chore. A robot with true wall-climbing ability saves you from manual brushing. The Letexpool C1 and the EZIOOV U8 both excel at climbing and scrubbing, reducing the need for chemical treatments. For more details on traction, check our best pool cleaner wall climbing brush review.
Filtration and Debris Capacity
Fine particles like sand and silt require a robust filtration system. Dual-layer filters and larger debris chambers capture both large leaves and microscopic dirt. The EZIOOV U8 has a 4-liter top-load filter, making emptying quick. The CliBot S5 uses a large top-load basket as well. If you prioritize dual brush efficiency, our Best Pool Cleaner Dual Brush in 2026 article may help.
Ease of Use and Retrieval
No one wants to fish a robot out of the deep end with a long pole. Auto-parking and directional return features bring the unit to the pool edge when the cycle ends. The Tnbacious and CliBot S5 both offer automatic docking, while the EZIOOV U8 docks and drains quickly. The Letexpool C1 can be controlled via app for route customization. Simplicity matters, especially if the whole family uses the pool.
Final Thoughts
After evaluating these four cordless pool cleaners, we believe the [2026 NEW] C1 Robotic Pool Cleaner with 180Mins is an excellent choice for large inground pools thanks to its app control and 180-minute runtime, while the Tnbacious Cordless Pool Vacuum Robot for Above offers unbeatable value for smaller pools and first-time buyers with its lightweight design and automatic docking.

Frequently Asked Questions
Can a robotic pool cleaner under $300 handle an inground pool?
Yes, many budget models like the Letexpool C1 and CliBot S5 are designed for inground pools up to 3,200 square feet. They offer wall-climbing, long battery life, and adequate suction to keep larger pools clean. Just verify the coverage area matches your pool size.
