Bought a Tiger Shark robotic pool cleaner after Mark took me through all the features he loves about it. It's always a concern when buying new pool technology. Will it work? Have I just been duped? Well I've had it a week and it's been fantastic. Climbs up the walls and cleans the top run tiles. Works its way around the pool silently. Can't do the steps however this is not a major concern for me.
It costs more than a Creepy for sure, however, it does a better job.
My advice, if you buy one make sure it's from a salesperson who knows the product and can give you good advise.
Thanks.

Have all the products required to maintain your pool. Offer expert advice and you are able to take in a water sample as often as you like for testing.
