Stochastic means a collection of random variable indexed to a set. You and Vac Facts like to throw around scientific sounding terms without even knowing what they mean. That might fly with people who didn't do math or statistics for a living but I did. You two are not fooling me with your...

I know. Getting old ain't for sissies! I told my wife that when I go I want my collection to go to the Museum of Clean in Idaho unless our little man wants to keep some.

It's beautiful. Are you going to use it with the cord winder?

Scientists and engineers are developing ways to recycle electronic components and batteries to recover the valuable materials. I know the US military does this already when they take old weapons out of service for disposal. The electronics go someplace where the expensive materials are...

I want a vacuum that will last 30-40 years. I don't do throw away. A Sebo, Aerus, Patriot, Miracle Mate, Metrovac will last that long given reasonable care. A Shark or Dyson never will. The vacuum I use the most often is a 43 year old Kenmore canister with some modern upgrades ( modern motor...

Based on public documents of Europro ( Shark )'s lawsuit against Dyson each company spent over $1 million to have labs like Intertek and IBS perform just the ATSM F608 Embedded Dirt Pick Up Test no hobbyist is going to reproduce the ATSM tests exactly. But that should be the goal to get as...

I didn't say make it in Germany. I said give it the kind of materials, textures, and feel of other Sebo products. Using traditional Sebo attachments would have set it apart from the rest of it's competitors. Instead Sebo made it look as cheap and nasty as the rest of the cheap squeaky brittle...

I don't believe for a second that engineering a bagged vacuum is somehow more expensive and consumes more engineering talent than engineering a bagless vacuum. Document that claim or it's pure bovine excrement. Bagless machines require a steady drumbeat of new filters and the owner has to get...

Vacuum Wars has the best test procedure by far. The one and only criticism is that their technique for measuring airflow is wrong and over states actual airflow. In every other respect they have a very good, repeatable non subjective series of tests.

So there is zero R&D effort designing bagless vacuums? Maybe you don't want to answer that, lolololololol.

Kenmore has fantastic synthetic HEPA dust bags. The thread was about aftermarket bags so I didn't mention them but yes Kenmore bags are the best.

Wow. I bought a Stealth PB14 and put the Lindhaus canister neck in it to use with my Aria canister in place of the PB12 it came with. I've never had a problem with a wider nozzle in any room, even ones with a lot of furniture, cat toys and the like in them. The neck used on the Stealth is...

I think we beat this up several months ago but your way of measuring airflow greatly overestimates it. You need to measure the inside diameter of the hose, calculate the surface area of the opening and measure air velocity using your anemometer. Multiply the airspeed in feet per minute by the...

Don't we all wish we had the bodies we had in our 20's ! But I like to say that age and treachery overcomes youth and strength. During WWII nobody made consumer goods or civilian automobiles. Every company was producing equipment for the military. Someone who knows can maybe tell me but I...

Completely different from what was sold in the US and I believe also Canada as the Viking Huskvarna V720. Here is an image of one from the internet ( haven't cleaned mine up yet so no photos of mine ) https://i.ytimg.com/vi/psmJJ_PalFI/sddefault.jpg

Every once in a while one shows up on ebay.

I see some of that in the US too. Our nearest Lindhaus dealer in Bakersfield California ( home of the Buck Owens sound ) very strictly deals with commercial users. Stocks nothing for my Aria canister, not interested in even ordering anything for it. I am using a dealer in the upper Midwest...

Air Watts are an instantaneous measurement of both suction and airflow simultaneously at a given orifice size. It's a snapshot in time. Suction and airflow will be different for every orifice size with suction increasing and airflow decreasing as the size of the orifice is reduced. Suction...

I have a Kenmore 600 and it puts both the Lindhaus and the Pro Team back on the trailer for airflow.

Metal brush roll? Oh my O_O That is quite a find.
