Ultra Nebula Cordless Pool Vacuum Robot, with 5580 GPH Suction, 180 Mins

The CoasTeering Ultra Nebula is a cordless robotic pool cleaner engineered to automate pool maintenance across large surface areas. Driven by three brushless motors producing 5580 GPH of suction, it picks up varied debris including fine sand, hair, leaves, gravel, and small twigs in a single pass. It provides a simple solution for pool owners who want to eliminate manual scrubbing without dealing with tangled power cords or hoses.

Navigation and surface coverage are handled through an automated mapping system. The robot systematically covers the floor, walls, and waterline, utilizing PVA rollers and high-traction tracks to climb inward-sloping walls up to 108 degrees. Users can select from four distinct cleaning modes to tailor the cycle to specific pool layouts, whether the pool is in-ground or above-ground.

Battery performance is geared toward larger properties, offering up to 180 minutes of continuous runtime to clean pool areas up to 3,229 square feet. When the battery depletes or the cycle finishes, the cleaner parks itself at a preset spot along the pool wall via Smart Directional Return for simple dry retrieval. Recharging takes between 2.5 and 3.7 hours.

Operation is limited to a single physical button on the unit itself, meaning there are no mobile apps or remote controls to manage cleaning paths manually. While it is built with reinforced bearings and a planetary reducer for durability, the product listing does not state the internal filter basket volume or total dry weight.

Verdict: The CoasTeering Ultra Nebula is an excellent match for owners of large concrete, vinyl, tile, or fiberglass pools who want strong suction and thorough wall climbing without cord management. It provides reliable, set-and-forget automated cleaning for both freshwater and saltwater setups.
