Pentair Kreepy Krauly Prowler 920 In-Ground Robotic Pool Cleaner

Is this Kreepy Krauly Prowler 920 Robotic Pool cleaner safe to use on a pool that has a vinyl liner?

Yes, it can clean on vinyl without issues, along with fiberglass, granite, pebble and tile pool floors, stairs and walls.

Does this clean walls and if so, does it go up to the water line? Thanks.

Yes, it climbs the walls then it just breaks the water line & sends itself back down. It's able to sense the configuration of shapes and depths of the pool.

How long is the cord?

Hello, thanks for the question. It comes with a 60ft floating cable. Thank you.

Can this be used in an above ground pool?

No, this is designed specfically for in ground pools, thanks.

Are the instructions clear on how to install the filter screens? I've read reviews that indicate the instruction manual is lacking in clarity.

Here's the manual for the Pentair 920. Page 5 has the instructions for the installation of the filter, removal and cleaning. Pentair 920 Robot Pool Cleaner instruction manual

What does the 920 weigh?

It weighs about 30 LBS.

Does it pick up algae ? And at what micron size?

If algae is already in the pool, it may reduce some of it. Regular pool cleanings will prevent further algae build up. Its two filters clean at about 2 microns which do require regular cleanings.

Is the power cord on a swivel to help keep it from getting tangled up?

No swivel, but the cord never gets tangled because of its design. It is not an issue.

What is the main differences between the Prowler 920 and Prowler 930? Is it just the bluetooth?

Yes, the Prowler 930 has the bluetooth and app control features.  It also comes with a caddy.

Can the 920 stay in the pool for a week or more or should it be removed daily?

Hi there, Thanks for your question. Best practice is to remove the cleaner from the pool after each use. It doesnt have to be immediately after, but I would recommend within a few hours of finishing. Cheers, -Eric

How long is the cycle time on the 920?

It's about 1 hr to 1 1/2 hrs per cleaning cycle.
