Miele Guard L1 vs old C3 - airflow through the hose?

[eurekaprince]

Does anyone know if the airflow through the hose is worse or better on the Miele Guard L1 vs the old C3? What about the old C1 vs the new compact Guard S1? Curious as to whether the airflow is better on the old models. You really can’t beat the airflow on the old C3/S8 canisters.

A modern Kenmore 600 puts anything Miele makes to shame for airflow. 72 cfm at the hose end. No other vacuum from any manufacturer that I have measured can match that. The best Miele is around 60 cfm. The 600s attachments, hose and power nozzle are vastly better than anything Miele ever sold. I have some Mieles but basically hate using them, so I don't any more and my wife in particular loathes them. The hose is simultaneously too stiff and it has this built in curve that fights you and either kinks or it flips the canister over. I can't tell you how many times I watched my poor wife wrestle with that hose and end up with the canister on its side. Part of that is because the hose is too short ( Sebo, Kenmore, Patriot, Aerus, all have longer hoses ) and part of it is the material they use. A Sebo hose looks the same as Miele but is much nicer to use. Kenmore and Aerus hoses are entirely different, heavier but supple and they never fight you. Miele attachments are cruel joke, especially their pinche useless little dusting brush. Then you consider their treacherous bag dock and grossly overpriced bags and filters and this whole infatuation with Miele escapes me. Nein, danke.

I like to use my s6, however I don't like worrying about the darn bag not being in the right place.

I almost bought one, but I saw somewhere online that the Guard L1 is slightly less powerful, but I can't remember or find where I saw that. Maybe it is what psychology calls a 'false memory.' But, I do remember thinking, "man, why would Miele make it less powerful than the C3?"

The [US] Complete C3 is rated @ 158 CFM, 111" water-lift.

Sebo K3, E3, and D3 models are rated @ 120 cfm, 95" waterlift.

Kenmore 600 Series is rated @ [greater than or equal to] 67 cfm; and 83-inches sealed waterlift.*

*NOTE: Kenmore's power figures are unconventional. Typically, manufacturers list the maximum figures, not the minimum figures.

Truthfully, all of these machines felt like they had a good amount of power, but still lacked in other areas. Less-efficient filtration, flimsy fittings, awkward usability, required more effort, stopping/bending over, and/or lost carpet performance after just a few uses (Sebo E3, D4).

If you know of any other canister with manufacturer-listed airflow and suction figures that are on-par or surpassing the Complete C3, let me know in a reply. I like to compare figures, but I only use them when they're manufacturer-listed. Ristenbatt and Sylvane are two sites I use to find CFM and waterlift ratings. If it's an amateur score, they're interesting but not credible without being able to compare to OEM-listed ratings.

This problem is allegedly resolved in the Guard models, and I wonder if the Guard's ComfortFit bag dock is backward's compatible with the older Miele models. It looks like the Gaurd M1 bag dock would fit the C3, when comparing photos of C3 and M1 bag compartment, bag dock, alignment tabs, etc. I might just try it out, one day.

I had a feeling that the convoluted path the air now takes in the Guard L1 might result in less air flow through the hose. From what I can figure out, the dirty air gets first sucked into the bag as before, but then it goes into a channel on the bottom of the canister and then makes its way upward into the fan chamber then is expelled forward through a Hepa filter facing forward into the new exhaust air gap in the middle of the canister. From this new air gap, the exhaust air is diffused out each side of the body.

The guard L1 has the same motor as the previous model, the complete c3. Some machines with the same motor will have different performance from different air paths. Think of a kirby. Kenmore is probably measuring at the hose end while miele and sebo probably measure at the machine.
