I have a question about Central Vacuum.

[tolivac]

It happened was able to get the MD Airmaster unit from the return pile-this machine had a motor failure-was a flowthru motor The vacuum is hybrid can be used bagged or bagless.The machine was being used with a bag when removed from service.Very fine dust went thru the bag,thru the filter and into the motor compartment and motor.Mike and I cleaned out the motor compartment and installed a replacement bypass motor-only type he carries in stock at this time.The machine works fine!!Since it has no utility inlet made up one for it.For a bag using DVC Filtrete style bags for a NuTone vacuum.Has a translucent lower dirt/bag bin.There is a bag horn to mount a bag on.I looked at the DIN cord and plug-and the connector on the machine-they are prestine-no burning.Just make sure the connector is FIRMLY seated!!!So far the vacuum works well with the 50Ft hose and the Volt powernozzle.This is a favorite powernozzle-no other plug required.Just charge the Volt battery when it gets low.Oh yes-when I use the Viper vacuum-love seeing the motor brush "flash" on startup!!Sort of cool.The Viper unit is hybrid,too can be used with a bag or bagless.Use it with its 9gal HUGE filtrete type bags!

cyclonic units

I believe all true cyclonic units use bypass motors but I would avoid these units for several reasons. First, they are required to be vented outside. Second, they are bagless and as with all bagless vacuums other than perhaps the water filtration machines, are a mess to empty. Third, with these units, you have to clean a screen inside the unit whenever you empty it, this is often quite difficult. Finally, you have some of the dust going through the motor, supposedly these motors are designed for this but in many of these units, the motor life is much shorter because of this. Here is an article that provides more details about why these units should be avoided.

I'm with Reggie, I'm really impressed with those thru flo motors on the Flo-Master line. I've used both the M85 and this F650t, it is one of the best single motor units that I've ever used. WAY better than alot of units I've used that uses a bypass motor. There's a good chance that I may end up putting in a F650t in my own home one of these days. Either that or maybe the M715h instead. I think the S900r/r2 or the M965h/h2 would be a bit much for me to handle, I'm not sure yet. And speaking of which, so far no one has talked about it yet. MD just recently released two new models on their website called the M850h and the M850h2. Boy those two sure do have ALOT of waterlift ratings.

Regarding cyclonic units, personally I don't think they are that bad of systems at all. Yes you would need to vent them outside but I would actually prefer to have a system vented outdoors anyways, regardless of which filtration method that it would be. It helps keeps the noise level down and it blows most of the dirt and carbon dust outside instead of back into your home. Emptying them I find isn't really a pain to do as long as you use the trash bag and a clean toilet brush right. On the Vacuflo units, I find that it doesn't clog nearly as much as Vacumaid and ACV to where sometimes you wouldn't really need to clean the screen out. Which by the way, ACV "All Canada Vac" is another Canadaian brand of central vacuums you can find in Canada that I would recommend. They used to sell them in the US but they left the market or at least don't have any US dealers at this time. Anyways with proper care and maintenance with those units, you shouldn't have a problem with them. If bags were to be getting more expensive and/or harder to find in the future for either an MD or a Cyclovac, I may as well go for a cyclonic unit. Either the Vacuflo 760 which I think that's what I would be leaning towards on or the Vacuflo 566Q.

At the point I can install a central vacuum I may very well walk away from the dual purpose wet/dry unit(s) as that would be a bag less system to accommodate t wet cleaning. From what I was reading a few years back a unit I saw will of course need to drain into the waste lines for wet cleaning and that one also used a spray of water in the unit to trap fine dust. Which would be ok. Other than the potential to clog up the waste lines with hair, carpet fuzz or any large object. Rainbow recommends not emptying the basin it the toilet for that reason.

And if you have a screen to clean anyway I would just go with a filter bag or easy to clean/replace permanent filter.

Opt for Dry vacuuming with the built in and continue to use the commercial box extractor I have for wet cleaning.

@ n0oxy

Reading the article and seeing the picture below the article I can see where that would be a serious issue. The hair and or carpet fuzz especially.

That happened to dirty air vacuums often with the carpets of the day when the yarns were not heat set like they are today. We had the long shag carpeting of the day in the living room.

If the fan blades had any nicks in them that is were the carpet fuzz would collect. fortunately that was easy to access and remove. But no less a pain at times.

Thankfully today once you remove the loose fibers from the shearing process shedding of fibers isn't as much of a concern.

Drainvac Viper and Powerhouse

These two Drainvac units use Domel flow through motors and they work great, they are very quiet, you can actually have a normal conversation in the same room, the Drainvac Viper is probably the most powerful single motor unit on the market.
