Favorite Straight Suction Vacuum made?

I am very pleased with my Miele C3 FreshAir suction only canister vacuum. It was a limited-edition Canadian version of the highly-rated Miele C3 Alize. It has an extra-long telescopic wand, SpotLight ergonomic handle, AirTeq carpet nozzle - which is super effective for cleaning low pile rugs and bare floors, and very quiet operation.

It’s a pleasure to use! Just wish Miele would offer a plastic tool caddy for all the extra attachments I’ve bought over the years (mini turbo, universal dusting brush, flexi crevice tool).
 
“Straight suction” is kind of a misnomer. The term that should really be used is “suction only”. This refers to a canister/cylinder/tank vacuum that does not have an electrically powered motorized power nozzle with revolving brush roll for cleaning carpets. These suction only vacuums may use an air-driven turbo nozzle to clean carpets, but no second electric motor in the carpet nozzle.

“Direct Air” or “Clean Air” refers to the position of the bag in relation to the suction fan. Direct Air vacuums have the dirty air going through the fan first before being collected in a dust bag. Clean Air vacuums have the dirty air go first through the filtration bag, then secondly through the motor. I prefer the terms “Fan First” or “Bag First” to describe the two configurations.
 
central vacuum free standing and direct air machines

As Tolivac said, using a central vacuum unit free standing with no pipes is awesome, it's very powerful when you connect the hose directly to the unit, I run all of my central vacuum units this way.
The direct air, or fan first machines have the advantage of cleaning carpets very well because the airflow is very close to the floor. The down side is that you must be careful what you vacuum up because whatever is vacuumed up goes through the fan before getting to the bag so vacuuming up hard or pointed things could break the fan, although I think fans have improved somewhat in recent years to minimize this. One place where you definitely would not want to use a fan first machine is in restaurants.

Clean air vacuums don't fare out to well in restaurants either,esp if the user tries to pick up a whole HAMBURGER with the vacuum.This happened with a Carpetpro at a former burger place that has closed.For restaurants a backpack machine works well for the non eating areas.Other wise the place just needs to be cleaned with a truckmount machine every month or so.Most places I go to use the Bissel type sweepers in between diners.A teruckmount contractor I talked with says that eateries were his most frequent customers.The greasy dirt just doesn't pick up well in ANY vacuum cleaner.
 
Yeah, I'm not sure anything would destroy a vacuum faster than using it in a restaurant. My Legend II looked like it was used in a restaurant; there was so much grease built-up and caked-up in the nozzle and fan chamber. Took forever to clean all of that out.
 
Miele C3

Quite simply the Miele C3. It just have everything what I want from the canister vacuum cleaner. In the Finland Miele has extremely good reputation and they sell well despite they aren't cheap. Picture taken from the Finnish "Gigantti" electronic appliances shop site. Price 299€.

Another striaght suction vacuum I have-is made up by the Sew&Vac place here-the "Port-O-Vac" this is an MD central vac unit mounted on a janitorial cart-also I have one that has a ProTeam backpack unit mounted on the cart.Either of these works well with a Volt Powernozzle.
 
another great machine

Another great little central vacuum unit is the Drainvac Atomik, I love this machine, it's small but very powerful. It includes a straight suction hose but you could easily connect an electric hose to it if desired. And if you decided later that you wanted to connect it to pipes, you can do that too, the design of this machine is awesome.

Mike: You inspired me to order the Drainvac Atomik!!!Just ordered thru your link.Does sound like a NICE little machine--but don't let its small size fool you!Since its sort of portable would be good for the car!!!Maybe the Sew&Vac place could mount this on their cart!
As other members point out the NSS M1 is a direct air "canister" vacuum.There is a large chamber in its "snout" to trap lsarge heavy items.--Its fan is TOUGH,though.I am amazed what it can "eat"!Conduit knockout slugs,6 in piece of Romex,nails,and such.Used one of mine for a home renovation cleanup-did better than my friend Sears shop vacuum.And used it to clean his fireplace!The fan was undamaged!!The trailing blades are almost quarter in thick!
 
Drainvac atomik

Tolivac, that's awesome, I can't wait to hear what you think of it, I think you will love it since you're like me and like to use central vac units free standing. Unless yours is set up differently it should come with a utility valve already screwed in to the in-let, you can easily remove it though if you want to connect to pipes. You can use the hose and tools that come with it or another hose, it sounds like you already have plenty of central vacuum accessories. Wait until you see how portable it is, it has a nice carrying handle on top, the bags are not as large as other central vacuum units but this vac was designed to be portable. You could mount it on a cart but there's really no need, it's so easy to carry, just put it in a convenient place and connect a central vacuum hose, again, can't wait to hear what you think of it. When I first got it, I thought it was not going to be as powerful as other central vacuums since it's much smaller, but I was pleasantly surprised, when using pipes, it can handle a home up to 8000 square feet. I honestly cannot think of a single thing I don't like about it.

I am waiting for my Atomik to arrive.the order has been placed they have to tell me when I am supposed to get the machine.Anxious to get it-have ordered other stuff,too-a new NSS M1,A Polarian PH50 light with a snap on green filter designed to allow you to see dust particles-according to Polarion the filter is used for airborn dust tests.The PH50 light is for my lighting collection.It is an awesome portable light.An inheritance is allowing me to get some things I have wanted.--and refinance my house.
 
the m1

Hopefully your atomik will arrive soon, mine arrived in a few days after ordering. I have thought about getting the M1 since I love canister machines, that's the only direct air canister that I know of, most canister machines have the bag before the fan.
Mike
 
Once you try a M1 you will LIKE it!!Its heavy,but rolls very easy on its large wheels-body higher off the ground than other canisters.the bag support rod can serve as a handle to move the machine where you want it to go.And it has places to keep your favorite hand tools.The hose is not as long as a central machine-but longer than other canisters-and its 1.5"there are adaptors for 1.25".also the M! is built to last a good long time.Its motor turns at a lower speed than other vacuums-plus the motor brushes are larger as well as the bearings.The current bags can be used as a dump bag or with paper bags.I have used Kirby G bags in mine as well.6 Gal Shop Vac bags will fit-but you have to press hard to get them to fit over the M1 bag horn.I have used one of my M1s to clean out radio-TV station transmitters and sites-one TV transmitter had so much stuff in it that the NSS paper bag was chock full-put it on the station managers desk to show him how much stuff was in his transmitter causing arcing!Got som,e good money from them so I bought another M1 and it goes on from there.A drain vac would be good for that type of job,too.
 
the m1

How much does the m1 go for, can you still get them new? How is the suction and airflow? I know that direct air, or fan first machines are known for not being as powerful at the hose end. It sounds like the Atomik bags are much smaller than the M1, they are no where near 6 gallons, that cleaning job would have probably filled several Atomik bags, mine came with a bag installed and an extra replacement bag. I'm not sure how they got that much power in to a machine that small but it's a great little central vac unit.

The NSS M1 DOES NOT have high suction "pressure" but works on VERY high CFM airflow.Unlike central vacuums and other clean air canisters the M1 has only one suction fan.when used with its 1.5 in hose the airflow is very impressive.It easily compares to any of the central machines for air movement and power.The M1 Pig has a 12A 8,000 RPM motor designed to last for over 12,000 hrs.Compare that to 1200 hrs on other types of vacuum motors.The brush life is over 2500 hrs-typical vacuum motors the brush life is 500-1000 hrs.The capacity of the NSs bag is around 6 gallons.NSS says something like 2.5 bushels in the dump bag mode-less with the paper insert bags.I use mine with the paper bags.On the NSS website and YouTube they show the M1 "Pig" being used for high up cleaning jobs with the 10 ft 1.5 in hose and 30Ft rigid wands.It has the airflow to deal with these situations-other vacs couldn't handle that.A central one should like the Pig.The 1.5 In airflow for the Pig is like 150 CFM.The suction pressure is low but the CFM makes up for it-when you try a Pig you will see.
