A Scien-TIM-fic Comparison!
I've never noticed your profile pic before turquiosedude but it's great!
I'm used to the Filter-Flo family, I have a HP Rim-Flo as my full-size which works pretty well, but I like the filter hat GE better. I also have a Lady K portable that frankly does an amazing job at catching muck. I like filters that can be cleaned like the GE and the Lady K, the Hotpoint's filter-ring gets nasty after washing cat blankets and frankly I feel that the GE setup could do it better.
As a comparison, I had 2 identical fleece blankets and I washed one in the HP and one in the Lady K (I'm my own Consumer Reports!) at the same time and was amazed at the result. The HP was on "Low" water setting which is about as much as the "little lady" uses on full (seriously, the GE's use a lot water on "LOW") and they completed the cycle with the lady coming in first there. Once they were done, it was very clear which one won the battle of the cat. The Lady K toasted the Rim-Flo! The little plastic nails lint cartridge was so full of crap I had to take a brush to it, but it caught it all, there were really no visible hairs on the blanket. The blanket out of the rim-flo still had many visible hairs on it. At almost a 10 minute and portability advantage, the little lady wins round one!
So to take it further, I decided to stack the Lady K 110V dryer against the HP TOL, "Infinite Buzzer" dryer. Coming in at a wopping 220/240V AC, this full size monster will surely de-lint/de-hair and outrun the little lady dryer. WRONG! In an upset the Lady K dryer, weighing in at 110V/1450W dried the fleece in 30 minutes while the auto-dry in the HP took 45 minutes before going into cool-down. Also not only did the little lady dry that quicker with less power, it removed pretty much all of the remaining cat hair from the blanket. The HP dryer removed a lot of hair, but there was still a lot on it. I ended up washing the HP's blanket and drying it in the Lady K set to get wonderful results!
Anywho, this test really only proves that the portable Lady Kenmore set are very efficient at what they do. The lint/hair filtration system for that machine is very well suited. It used slightly less water and both used much less electricity. The Hotpoint would be more efficient with a full load to wash and dry. The Hotpoint's GE filtering system has the potential to be MUCH better but the rim system is definitely a worse performer than the filter hat system. The Lady K set was at near capacity with the fleece blanket, which is pretty light and easy to move in water once saturated. The Hotpoint would have held 4-6 of them on "full" and the dryer probably would have only taken 15-20 minutes longer to dry. The HP dryer seemed to do a good job of lint/hair removal, but it relies on the washer to remove a lot, which it didn't really do.
From an efficiency point of view, if you have small loads here and there like I do (single guy), then the Lady K set are great and use less resources. If you have a lot of laundry (after being lazy for a week or two) then definitely the full-size. It's more efficient from both an energy and time standpoint.
To pull this post back on topic, the Kenmore "bed of nails" cartridge performs better in the smaller machines than the Hotpoint's "rim-flo" collar does in the full-size.
