Have they're ever been any? I think I've heard of them. I'm just not sure.

The NSS M-1 Pig is supposedly one of the most powerful fan-first canisters of its kind.

Pacific Steamex

Looks like they (Pacific Steamex) made a nice NSS-like canister as well - in fact I like the nice metal finish on it a lot better.

If you mean "direct air" . . . .

I think not. Hoover did make a model that could be dragged along on metal glides but its bag was not enclosed in a container.

Does "canister" apply here since the dust bag is external?

You're right, venson

Hoover did make a model known as the Hoover Duster (or Minor in the UK), during the late 1920s and early 1930s. It was essential the motor and fan housing from their model 575 upright, positioned horizontally on a pair of runners,which exhausted dirt into a small, external fabric bag. It could be purchased with its own attachment set, or you could also buy just the power unit and use the hose from your Hoover upright. An intriguing idea, but one that could not compete.with the fairly well-established design of the Electrolux cylinder cleaner. It wasn't until 1947 that Hoover started manufacturing a true.cylinder cleaner that could.successfully compete with Electrolux.

@raycarter . . .

Thanks for the helpful history!

Thanks again Ray Carter. I found a video of the Hoover Duster.

Slightly similar by way of the idea, I know uprights like Kirby could/still can be broken down to canister style (handle removed, bag folded over) and I think there was an early Electro-Hygiene upright that could be fitted with a smaller bag, attachments, etc.

The "pig" vac was and probably still is quite popular in theaters and other public venues in New York but I have never seen them pressed into service for domestic use by housekeepers or cleaning services.

I remember seeing...

at a restaurant in Florida in the mid 1960's several vacuums that looked like the NSS

"Pig", except it actually had an upright handle with a grip to move it with. The bag was attached at the top of handle, not folded over. They were aqua green. A man was cleaning the fan of one of them (AT THE ENTRANCE OF THE RESTAURANT INTO THE HOTEL LOBBY!) the fan was the size of dinner plate, and the hose/wand was 1 1/2" diameter, S shaped, with a straight suction rug tool. Never saw any like them ever again.

I don't know if you could consider the machines described here as "canisters" but they are used AS canister vacuums.The NSS machines do have an advantage over many canisters--their motors are running at a slower speed-so they last longer-even last DECADES.Like the sound of them.would like to encounter a Pacific Steamex version of the NSS-their version isn't listed on their website-bet NSS had something to do about that.and what about external filter vacuums such as the Tornado or the NSS Broncos that had external filter bags.the motor blower unit sits on the tank lid-and the bag is connected to the blower outlet to catch very fine dust.The ext filter NSS Bronco is another one of those on my "Most Wanted" list.and these tank type vacuums can be used for wet pickup if they have the ball valve on the lid.I enjoy the three NSS "pigs" I have-at some point would like the 100th Anniversery edition one.

Many moons ago...

The elementary school and high schools I attended used NSS model M1 "pigs" to vacuum the classrooms. I remember hearing them running clear across the other side of the building whenever I attended nighttime school events. A roller skating rink near my home also.used them to vacuum the party room and snack bar areas.

Woodshop Dust Collectors

Can't believe I almost forgot -

Woodshop dust collectors - remember them fondly for now, I wonder what the waterlift on these machines are? Tons of videos of them around.

A woodshop dust collector isn't really considered a vacuum cleaner-the water lift,indeed,is too low to use as a vacuum cleaner-these devices were designed to pick up sawdust and wood chips,shavings at a woodworking tool as they were being generated.At best some dust collectors did have a wand and floor nozzle of sort to pick up sawdust from a shop floor-and large dust collection systems had "floorsweeps"suction inlets along the wall to the floor so someone could sweep the sawdust to the floorsweep and it would then get pulled into the collection system-and----some dust collection systems are filter first(cyclone) so the large wood chips,shavings would not go thru the fan.only the very fine dust-like sanding dust would go thru the fan and into the dust systems baghouse filter or very large pleated filters.And on these systems--the filter first is good so a nail won't get ingested by the fan causing a spark--and a dust explosion or fire.The small fan first dust collector have some sort of barrier in front of the fan so woodblocks and nails can't get into the fan.Those can get clogged by shavings from a jointer or planer.So if you are using the planer-you will have to unclog such a unit a lot.Planers can generate MOUNTAINS of shavings-esp large planer planing wide boards.
