Leaves & Large Debris
The 4L basket is helpful for homes with trees, pets, kids, and frequent backyard debris.
Fine Particles
The 180μm filtration claim helps with small debris. However, very fine dust may still need support from your pool filtration system.
Waterline Grime
The wall and waterline cleaning feature is one of the biggest reasons to consider the K40 over a cheaper floor-only cleaner.
