Woot is selling new Blue Pearl Robotic Pool Cleaners for $399.99 + $5.00 shipping. They sell 1 item a day from midnight til midnight or until the item is sold out, whichever comes first. Woot is not an online pool store, so pool items from them are rare.
The Blue Pearl is manufactured by Water Tech and usually sells for around $600.00. It has a manufacture's list price of $999.00, but Google shows most pool stores sell it for less.
I have not used this cleaner so I don't know if it is worth the price. The website says it is good for "all pool surfaces".
Thought I would pass this information along in case anyone is shopping for a robotic cleaner today!
