riccar impeccable
I did not know that the impeccable had a two stage motor, that's not very common these days. I would love to know if the immaculate and impeccable are the same canister and just different power nozzles, or if the canister and motor are different as well.
If the Guardian Platinum used a standard hose end and standard electrical connector, I would probably get one, but as I said, I want to be able to use any of my attachments and power nozzles, and if I can't, that's a deal breaker regardless of how good the machine is.
I have a Miele C1 olympus, it's a straight suction model, it works well, though Miele's attachments tend to be expensive. A much better alternative is to get an adapter to convert the hose end to 32 mm, then you have many more attachment choices. The Miele power nozzles are rebranded Wessel Werk nozzles, I've heard they are difficult to work on and have also heard that there are issues with the neck on those. I think the Sebo power nozzles are the easiest to work on, you don't need any tools to remove the roller.
So the Guardian Platinum uses a Dommel motor, from what I have seen, those are very good motors. My Purvac barracuda Central vacuum unit uses a Dommel motor and so does my Sanitaire backpack vacuum. Both are quiet and very powerful, so I'm sure the motor in the platinum is good as well.
