The Polaris 9550 looks like an efficient amalgam from Mother Nature: a cockroach walrus. It’s a compact, symmetrical unit. Its wheels are a tight, hugging fit on the main chassis, and its bristly mouth scrubs the pool floor. The 9550 is the flagship of Polaris's robotic line. The bristles come in a pair, scrubbing away dirt and stains caked onto the pool floor. Behind them, the 9550 is more of a cephalopod with its big vacuuming mouth on the underbelly. Every pool is a little different in its length and width and depth, but one user clocked the 9550 at 90 minutes to complete a 40 foot long pool. Aquabot's Supreme is a similar device.
The unit does its best work on smaller particles like sunken pet hair and dirt. Large leaves and sticks are more difficult and unwieldy to collect. Most complaints have focused upon the 60-foot cord. It's necessary to complete longer pools, but in smaller ones, the unit can tangle itself. Owners then have to free the 9550 by hand.
Polaris has been making robots since before they were cool. Their pool vacuums have been a staple of swimming pool cleaning equipment for over 40 years. Their classic lineup of sweepers, however, are not true robots. They use the pool's water intake to propel themselves forward over the floor of the pool, picking up whatever they can as the water pushes them. Water Tech's Speed Jet is an example of this style.
The 9550's assembly has received positive marks. It’s a simple setup, and its first operation out of the box makes it look like a pool veteran. Its remote control is responsive, with a one-second lag. Users can program the 9550 to scrub floors only or to hug the walls as high as the water line. It's expensive for a pool cleaner, but the 9550 has proven its worth underwater, which is no surprise coming from a veteran brand like Polaris.
The filter indicator is a cool feature that lets me know when to empty the canisters, and the easy lift system makes it easy for someone like me to retrieve it without issues.
Cleans well, passes over the drains with ease and even crawls up the wall on the exit mode so you can retrieve it from the pool.
The machine works great otherwise, but you will probably have to check the control daily to make sure it is going to operate the next day.
It cleans the tiles up to the water line, does the stairs, and the seats in the corners. Occasionally, I use the remote to get missed spots.
The robot comes assembled with the cord attached, and plugs into the control box mounted on the caddy. I was impressed by the build quality, fit, and strength of the parts
Does not collect all big leaves but the remote makes it easy enough to go back and get them. So far very good on small particles and dog hair.
This machine definitely does a very good job and even scrubs the tiles at the top of the pool. However, the cord gets tangled and needs to be untangled periodically.
This cleaner does a great job, was easy to assemble, and is simple to operate. This cleaner takes all the work out of keeping a pool clean.
Hands-down well worth the price. Nothing on the market compares. The best feature by far is the remote . . . Just turn on the remote and tell it where to go.
Programming manual is very poorly written. Very hard to program . . . Technical support did nothing but read the user manual, and did not understand it or help in any way.
