If you own a large inground pool over 50 feet, you already know the pain: cleaning it manually is a back-breaking chore. Even many standard robotic vacuums can’t keep up. They either tangle, miss spots, or fail to reach the waterline. And if your pool stretches 50–60 feet, a weak vacuum just won’t cut it.

👉 In this guide, we’ll cover the best robotic pool vacuums for large inground pools (50+ feet), compare top picks, share real-world performance, and help you choose the right model to keep your pool sparkling clean all season long.
