Funny you should ask. I've been contemplating the same thing and putting together a list of pros and cons for the Polaris 380 + booster vs robot. The electrican is quoting $975 for the stuff below:What's the electrician charging to upgrade to 40 amps? It might be cheaper to ditch the Polaris & booster pump & purchase a robot. The robot will also use a lot less electricity than running the filter pump & booster just to vacuum the pool.
- requires pump to be running, and for 30 minutes before it starts
- doesn't scrub
- requires booster pump that is loud and not energy efficient, although there is a newer quieter and energy efficient booster pump: PB4SQ for $428
- requires upgrading electrical panel if I want to be able to run pump, polaris, and SWCG at the same time. lowest quote I've gotten so far is $800, which only includes replacing the breaker in the main panel and running the wire to the subpanel. Other quote is $975 and includes wiring up new pump and adding a dedicated breaker in the subpanel.
It's in the manual for the booster:Never heard of needing the pump running 30 minutes before it starts. Where is that specified?
It's in the manual for the booster:
"If a time clock is used, set it to turn the pump on half an hour after the pool filtration pump is turned on, and turn the pump off at least half an hour before the filtration pump shuts off."
Perhaps they meant that for safety to give a buffer in case the timers get out of sync.
That's a good point. I need to do that regardless. Since the old pump is on its way out, I want to get the new pump installed as soon as possible, so I think what I'll ask the electrician to do for now is replace the two 20A breakers in the subpanel with 3 new GFCI ones: one double-pole for the new VS pump, one double-pole for the SWCG/Intermatic, and a single-pole for the Polaris booster.The panel electrical upgrade also gets your pool up to code with a GFCI CB for your pool pump.

You never provided the link for this last option you referenced, which I suspect is the one that I have, but I would add a caveat that if it is installed in a pipe that is below the pool water level, then the pipe will have water in it and the water will be bonded. Suspect there are many who install it on raised pipes at the pad though which, as you referenced, may often be dry.There is also this one but it should not be used in an in ground pool... only in above ground pool and really it should never be used...
WHY YOU SAY...
This one uses the water in the pipe to bond the water... what happens when you have no running water in the pipe.. Your pool is no longer bonded... You and your family and the pool are no longer protected.. Bonding is meant to keep everyone safe at all times and this one does not... If and when you winterize, pump broken, pump off, power outage, there are tons of reasons this should never be used...
WHY DO I PUT THIS ONE IN HERE...
Because someone will find it and use it thinking they are good to go and they are not...
