Extra cable length reaches deep corners of oversized residential pools where 60-ft cords fall short.
Point and tilt the handheld controller in the air to steer the 9550 Sport directly to leaf piles.
Extra-large 5-liter canister and wide intake mouth swallow large leaves without losing suction.
Includes a heavy-duty metal caddy with 5 cleaning modes, clock-time scheduling, and dirty-canister alert.
Climbs the wall you face and blasts water out the rear so lifting the 43.6-lb chassis feels lighter.
Climbs steps, steep hoppers, and tile waterlines with aggressive 4WD grip.
The 9550 Sport is the long-running large-pool Polaris. Its 60 ft rating and 70 ft cable put it ahead of most robots in this price band on reach alone, and four-wheel drive gives it the traction to actually finish the walls on a big vessel.
4WD isn't marketing here — on a 60 ft pool with a deep end, a two-wheel robot spends a meaningful share of its cycle slipping on the transition from floor to wall. Driving all four wheels keeps it moving through that transition and up onto the tile.
Polaris's vortex system keeps captured debris suspended in the canister rather than letting it settle and compact against the filter. That preserves suction across a long cycle, which matters most on exactly the large pools this model targets.
The motion-sensing remote lets you tilt to steer — useful for sending it straight at a pile of leaves in a corner instead of waiting for the pattern to reach it.
This is an older platform with a long review history and a mid-3s average. Most of the criticism concentrates on multi-season durability rather than cleaning performance. Read the current reviews before you commit at this price.
