Received mine today and can report the following, after having it running just the last few hours.
This is my first suction-side cleaner, I am coming from using a pressure-side Letro Legend, with no booster pump.
1- Overall build quality seems to be very good. Plastic components on the quality level of a Dyson vacuum cleaner. They look like they could have been made in the same manufacturing plant.
2- Comes with plenty of hose, enough for a 40K gallon 40x20 pool. Hose quality and connections very good.
3- Comes with a flowmeter type of (spring resistance) device in order to dial in the level of suction at the end of the hose, before you attach the cleaner.
4- The instructions indicate that you should adjust flow so that you get a "3" on the flowmeter (right in the middle of its range)
5- When configured at "3", the MX8 will not climb walls much, if at all.
6- Checking the manual, under troubleshooting, there is an item "does not climb walls". Answer: Increase suction.
7- When configured with full suction, MX8 climbs walls well.
8- I will be replacing my pump in the nest week or so with an Intellifo 011018 and then see "how slow can I go" on pump speed, and still get good wall climbing/cleaning action.
9- Weakness: Be aware, any fibrous, stringy materials from palm trees such as Queen Palms or Mexican Fan Palms, gets "wound" into the mechanism and will stop the MX8 dead in its tracks. I have already had this happen twice in the last couple hours, however, there was quite a bit of this stuff on the pool bottom after the wind/rainstorms we have had during the last week or so.
I will provide additional updates as I gain more experience with the MX8, but, so far I am pleased with it.
