Thanks for taking the time to reply so quickly Evan. It is appreciated. One more small question, since you work in the pool store environment you might have an idea on my concern.

I just finished watching the video on the website. It shows it climbing the stairs, it also says it climbs the walls. How will this rotating wheel affect my vinyl liner. Would you expect it to cause any damage or does it not really climb the walls like they are suggesting. Perhaps you can't answer for certain but your opinion would be appreciated.

That, and why they aren't recommending a robot are my only concerns left now after your feedback.

Thanks.
