Hey Owen, I just had this unit installed in my home a few weeks back. The unit is on a dedicated 20amp circuit with the unit in the Garage (plugged into a GFCI receptacle). Of late, i happened to notice that whenever I use the unit (after the vac is. idle and not used for a couple of days), about 30 to 90 seconds after the start up, the 20 amp breaker in the panel trips. Then after resetting the breaker, I could vacuum all day long without any more trouble. Is it due to the fact that the Square D breaker i have is sensitive to high inrush current? Do i need to replace the breaker with a High Magnetic one? Any advise to resolve this is greatly appreciated. MD support seems to be closed for the holidays.
Hi, it sounds like the breaker is more likely the issue...while a motor defect is possible, a bad motor would typically not be able to run for any length of time without tripping the breaker. Square D "QO" type breakers are quite sensitive (which is usually a good thing) and loads that approach their rated capacity can cause them to trip. You might try plugging the unit into a different 20 amp circuit, using a heavy gauge extension cord, to see whether or not that breaker trips similarly.
@@Centvac Thanks for your prompt response. (Please pardon and disregard my duplicate messages on another TH-cam video of yours as well as Instagram. I wasn't sure which one would get to you. hence tried them). I will try to plug it into a different 20amp circuit and see if it still happens. thanks again!
Hey Owen, I have a md f700t unit for a 3,000 sq foot house, 6 inlets, it works great. It replaced a 1989 unit that was shot. Do the flo master units use a similar motor to this unit?
Yours would have the Ametek 122264 motor. It is not quite as powerful and has a much shorter lifespan. They are actually quite different with the one in the video being an 8.4 inch tangential discharge motor while your unit has a 5.7 inch flow-through motor. That being said, it is still made by the same company and still great quality, so it can still last many years if taken care of. Just not as long as this Modern Day M715h unit.
I have a unit that uses this motor, the Vacumaid SR800, it's also a bagged unit, that unit is a beast, I would think for large homes where they want a lot of power, you would go for the Silent Master 900, that probably can handle a slightly larger home than the single 8.4 motor units can, I'm wondering if anyone will ever come up with a unit that combines two of the 8.4 motors, so far I don't think that exists, but talk about a beast, that would be it.
I agree, these are amazing motors. The longevity and efficiency makes them a great choice. There are actually two units available (that I am aware of) that use dual 8.4 inch motors… unfortunately they are both really only great for very specific installations. There is the Aqua-Air Model 258 that has two parallel motors in a separate pod, very similar to a VacuMaid S3600. However, it’s a wet/dry unit which increases costs and installation requirements. The other is the Allegro Pinnacle (MUA85E). However, this unit has the two motors in series (which creates tremendous water lift) but it would only really be suitable for large installations with retractable hoses or if you want the most power from a TurboCat head. I wonder if it would be possible to get a VacuMaid S2720 with two motor pods.
@@fidgetthedalmation7433 I looked up that Allegro unit, 210 water lift and 165 CFM, that would be great to add to my central vacuum collection but it has one issue that is a deal breaker for me, based on the description, it's bagless, I don't like bagless units because they are a mess to empty and dirt building up on the filter will decrease performance, I have several units that are hybrid but I always use those with a bag. I use all of my units without pipes since I live in an apartment, just attach a utility valve and plug in the hose. I currently have 5 240 volt dual motor units, some are in series and some are parallel, I like the series ones the best, when you connect a hose directly to them you can definitely notice a difference. I have the Drainvac Twin Turbo, that thing is a real beast, two Domel motors in series, it has 220 water lift and 145 CFM, the suction power on that is incredible, I have a Duovac Distinction, again, two motors in series, 208 water lift and I think 106 CFM, The Galaxie GA240, that's a parallel unit and it has 199 water lift and 215 CFM, the Silent Master S900, not sure of the exact specs on that but I think the water lift is around 140 and the airflow is around 200, and last but definitely not least is the Vacuflo DB9000, another series unit, not sure of the exact specs but the water lift is over 200. If that Allegro was a hybrid or a bag only unit I might have considered getting it but the fact that it's bagless is a deal breaker for me. I also have several units that use 120 volts, if you are interested I can list my entire central vacuum collection.
@@mikearrigo5674 Wow, you definitely have a collection of units! I only have a handful. Those sure sound like beasts! I’d love to feel the power of them. I don’t have any that don’t run off of a standard 120 volt 15 amp circuit, but I hope to get a more powerful one some day. Yes, I understand. The bagless ones can be a real pain, especially if you’re in an apartment. Some of Allegro’s other units are hybrid, but I’m not sure if the Pinnacle has that option. Maybe you could enquire?
@@fidgetthedalmation7433 You missed one, the Cana-vac Signature Series XLS-990, A Canadian machine that uses a sensible design. Of course, there's another big motor powered machine and it's a portable. It's not made anymore and isn't nearly as powerful, the Rainbow D4. The motor measures at least 8 inches in diameter and has a life span that makes most central vacuums blush at nearly 40-50 years (projected) and is totally service-friendly from top to bottom. That is something you can't do with a central vac motor.
Did you not look at this video? He just took apart a central vac motor for this unit to show the inside of it, it's definitely serviceable. Also, I have a Rainbow D4C and this would definitely out clean it. Not even close. In fact it's one of my least powerful machines in my collection even after completely restoring it.
Umm...no. You see the M1 is portable, this isn't. The M1 excels at airflow and is made for dusting hard to reach places. This is an illogical design as it has the motor on the bottom which if installed in some areas is susceptible to flood, where Cana-vac and Beam have the motor mounted on top. For repair reasons, it's illogical as well as you have to pull the bag and filter out and physically turn the machine upside down. Everyone else uses the bottom bucket and top motor design for these reasons. You don't waste time doing meaningless stuff to access the motor(s) ultimately costing the customer money and scratching their foolish yet expensive purchase.
First of all, both are commercial grade vacuums. Yes this MD M715h can be sold for commercial use. Secondly, you CAN use a central vac as a portable by building a cart. This has been done before and I don't think it's a bad idea at all but installing it and pulling the hose around is still lighter than pulling the NSS around. Thirdly this has a combination of both airflow AND suction which can easily spank the NSS because airflow can't clean by itself, not to mention that the NSS still uses a wire reinforced hose which is definitely outdated nowadays on the market. It's just like a tornado where it can pick a car up but it wouldn't go all the way up to the top of the clouds, it's no wonder why my Kirbys left behind ALOT of sand and heavier grit underneath the carpet that they were SUPPOSED to get because they don't have very good suction. Videos like from Performance Reviews can back up my statement. Fourthly, our last cabin had a MD unit before (yeah that makes me a fool too in your mind and I honestly find that disrespectful) and we built a deck high enough in the garage to the unit where we'd have easy access to the bag and WAY above the floor if there was ever a flood (which we never did). Still alot faster and easier to change than emptying the canister of our Beam at home. Also when our motor went bad on the Beam, the service technician had to get a ladder to dismantle the unit and take it to his shop to get it repaired and cleaned since nobody in our house wanted to repair it and I was too young to tackle onto it. Not everybody would feel comfortable servicing or replacing the motor out on their top motor unit or any central vac unit, that's why you have people like Owen here that repairs these for a living. But if you still prefer bottom fill bags, MD definitely has offers for people who prefer to replace bags on the bottom or even easily have access into the motor. Personally, I like changing bags on the top better. That's one of the reasons why I'm leaning towards of getting an top fill MD unit when I move to a new house soon instead of putting in the DrainVac that I have since I already know I like MD better than anything else I've ever used before including portables. And last but not least, the motor on the NSS is WAY closer to the ground than how high these top bill bagged units can be mounted at which means it'd have a more greater chance of getting water on the inside.
@@panasonicvac4036 So, to start off, try putting the cart in your car or heavily loaded cleaning van. The M1 wins here. Airflow is what moves the dirt, not suction. Suction is needed usually for picking up water and moving air along. This is what is required when using the M1 because you are picking up mainly dust on pipes, walls and ceilings. If you want to see a machine that doesn't have as much suction move a heck of a lot of debris, check out a dust collector. I would say look at Matthias Wandel's home made dust collectors for examples of low pressure (suction) machines that do a better job than his shop-vac. Your Tornado example proves my example. It's airflow in a tornado, not suction. Also, are you setting your kirby up correctly? The reason I ask is if two youtubers that know how to do scientific testing are able to pull sand from the bottom of a carpet with their kirbys, why aren't you? It also depends on the type of carpet, how thorough the vacuuming is and whether you got that carpet brand new or it came from previous owners with say...a dyson. Wire reinforced hoses are under-appreciated and are incredibly durable compared to the crush-resistant hoses, and tend to last decades. Crush resistant hoses are more prone to splitting than a well-made wire-reinforced hoses. I have seen wire-reinforced hoses that are decades old while most crush resistant hoses barely last one decade. Alex of Performance Reviews irritates me in the way he talks in his ego soaked voice, the way he talks about and to other people of the vacuum community at large and uses pseudo-science in testing vacuums (ie no measured results, just qualitative observations, the use of his weird little Y contraption that was made for the sole purpose of selling central vacuums and the fact that he doesn't use an anemometer). You need to move the air to move the dirt. I have never understood why suction matters in vacuum cleaners, unless it's used on a commercial scale to remove liquids from carpets like with a Kohler V-twin-powered roots blower-based truckmount. Also, you keep referring to MD as a top fill like it's the only one. Every central vacuum cleaner on the market today is top-fill. Beam, Cana-vac, Cyclo-vac, Aqua-Air, Drain-Vac are all top fill because the debris comes into the bag or bucket from the top of said bucket or bag. What MD and Central Vac International are is top empty. More or less glorified garbage cans with motor(s) attached to them.
There are some central vac units where they can be used as a portable with or without a cart. The DrainVac Atomik is one example (I don't believe it's being made anymore) and I think it was rated to up to 8,000 square feet. Definitely much smaller, lighter, and cheaper than the NSS. Back to airflow, I don't think you're quite getting where I'm going with here. But to make it short, my Kirbys have been used correctly and none of them have any problems. I brought up Alex here because he's been having the same results as I was experiencing with my Kirbys, making me conclude that I disagree with TH-camrs like Bill from Vac Lab so I don't get why I don't need suction to clean. Maybe in your area you don't see as much wire reinforced hoses go bad, but that can't be with everywhere else. I've seen crushproof hoses last for years even, heck all of my central vac crush proof hoses never had any problems of ripping. And I'm sorry to confuse you with saying top fill as I meant to say bottom motor. Just because you don't like the design doesn't mean that everybody else would agree with you. If they like it, fine. If not, they're always other options to choose from.
Can MD for once build the machine where the motor is on top? Servicing these things is probably a pain in the rear. Especially since the thing weighs more than it needs to be, the amount of time it takes just to get to the motor where you have to remove the bag from three points, lifting it up and over the machine, remove the filters, invert the machine, fix or replace the motor, invert it again, lift this thing back onto the wall, replace the filters, lift the bag up and over and down into the unit, fit all three bag intakes, you get the point. It's just a bad design. There's a reason why MD is the only manufacturer still using this design and the other one that uses this design still builds its machines like older Filtex units with the motors on the sides and to the front. Those you don't really have to remove from the wall. Most other units you pick up off of the wall, set it on the floor, remove the top and, there's everything staring you in the face. No bags or filters to remove and no inverting. Cana-vac still uses this motor in its XLS990, a machine that's still pretty easy to maintain.
They do make units with a motor on the top. In fact, I believe that their AirMaster XL A715h has the exact same motor as the unit shown in the video, but mounted at the top.
