The Polaris 9650iQ Sport does a pretty solid job when it comes to cleaning pool walls and the waterline. The manufacturer mentions it has 4-wheel drive technology, which helps it climb up walls and scrub the waterline effectively.
So, it's not just handling the pool floor but those trickier areas too—like the walls and waterline—where dirt tends to build up. It's a step up compared to some other robotic cleaners that struggle with these spots.
The cleaner's also designed to cope with different pool surfaces and shapes, thanks to a 70-foot swivel cable that keeps it from getting tangled as it moves around. This should mean less hassle for you while it's doing its thing.
From what we found, most people who have used it are happy with how it performs. Lots of folks say it picks up debris well and scrubs surfaces nicely.
There was one person who noted that even after four months of regular use, it was still climbing walls and scrubbing tiles like a champ, which speaks to its durability.
Of course, not everyone's experience is perfect. Some people had issues with the cleaner in uniquely shaped pools or mentioned occasional cord tangling.
But overall, the consensus leans towards it being effective in maintaining a clean waterline and thoroughly cleaning your pool.
So, if you're after a robotic cleaner that’s good at wall and waterline cleaning, the Polaris 9650iQ Sport seems like a reliable choice.
