Need some input before I make a decision. I bought a Pool Buster Max CG 2 years ago. I left it charging over night the other day and now it doesn't work at all. I contacted Water Tech and they offered me (3) options:

[Option 1, you can send in your machine in for repairs, now we charge a $45.00 labor fee plus parts it can range from $65.00 to $135.00 depending on what part you would need. That comes with a 3-month warranty. Option 2, you can purchase a new motor box for $90.00 plus shipping. It comes out to be $100.00. That replaces the battery, motor, and charger; basically it replaces all the electric components in the machine. That comes with a 3-month warranty. Option 3, we have a program called the Trade Up Program. Since you are an existing customer we offer you a brand new machine for only $155.00 for the Pool Blaster Max. Now if you wanted to upgrade to the Pool Blaster Commercial Grade machine that would cost $225.00. Shipping and tax is included in both prices, and also both machines come with a new one-year warranty.]

What's the difference with Blaster vs Buster? I feel like if I'm going to spend $100, I may as well upgrade but I'm worried I'll be back in the same position in the next year or two. I've trolled the boards and people are either for it or against it.

Any input will help as I can't go back to a regular vacuum hose since I replaced my o-ring(air leak) on the pump and now I don't have enough suction. An issue I'll deal with next year.
