10 Best Robotic Pool Cleaners 2025 in the UK

The Dolphin Nautilus CC Plus is a versatile robotic pool cleaner, designed for in-ground pools up to 50 feet in length. One of its major strengths is its wall-climbing ability, allowing it to clean all pool surfaces efficiently, regardless of their shape or texture. The active scrubbing feature is a significant advantage, reducing the need for manual cleaning and ensuring that pool surfaces are left spotless. The easy-to-use, top-load filter makes maintenance straightforward, allowing users to effortlessly remove debris and maintain clear water. This feature is particularly beneficial for those looking for a hassle-free pool cleaning experience.

The plug-and-play system simplifies the operation—just plug it in, drop it in the pool, and it will complete a cleaning cycle in about 2 hours. Its energy-efficient design is a plus for environmentally conscious users and those looking to save on energy costs. With over 40 years of experience, Dolphin promises durability and reliable performance, backed by a two-year warranty.

However, while the Dolphin Nautilus CC Plus offers great features, it may not be ideal for users with larger pools over 50 feet, as its cleaning capabilities are limited to this size. Additionally, while it offers smart navigation, it might not have the most advanced mapping technology compared to some newer models in the market. At 9.45 kg, it is relatively heavy, which might make handling a bit cumbersome for some users. Despite these drawbacks, the Dolphin Nautilus CC Plus ranks highly among automatic pool cleaners and is well-regarded in customer reviews, making it a solid choice for those with medium to large in-ground pools looking for a reliable and efficient cleaning solution.

The WYBOT C1 robotic pool cleaner is designed to handle in-ground pools up to 65 feet long, making it suitable for medium to large-sized pools. It offers strong cleaning power with upgraded dual brushes and an efficient water pump that filters debris like sand, leaves, and dirt from all pool surfaces including floors, walls, and waterlines. The cleaner runs on a rechargeable battery that delivers 120 to 150 minutes of cleaning time, covering a full session without needing a recharge, and it recharges fairly quickly in about 3 hours.

A standout feature is its intelligent navigation system, which uses sensors and gyroscopes to plan cleaning paths and reduce missed spots, including wall climbing for thorough coverage. This enables it to clean more methodically than some basic models. The top-loading filter cartridges are large and easy to remove and rinse, simplifying maintenance. The cordless design adds convenience by eliminating tangled cables.

However, it weighs over 10 kg, which could make handling it a bit cumbersome for some users. It also requires three lithium-ion batteries, which might add to replacement costs over time. Its cleaning cycle time is decent but may be on the longer side compared to some faster models. The WYBOT C1 is a reliable, cordless robotic cleaner with smart navigation and effective debris removal for larger pools, balancing good cleaning coverage and user-friendly maintenance well, though its weight and battery requirements are worth considering if you prefer a lighter or less battery-dependent option.
