Product review (5 stars): Compatible 10-ft drain hose: Frigidaire 154225602. The Haier HLP24E is the nicest washer I've used!
I've owned the Haier HLP24E portable washing machine for three weekends now, and have used it for 2-3 loads per weekend with zero problems.

Before I was able to use the washer however, I needed to find a 10-ft drain hose. Haier only supplies a 5-ft drain hose. However, there are 15 inches of countertop between the right side of my kitchen sink and the space that I could place the washer, plus the drain port on the washer is on the far side from my sink (on the right side of the washer, at the bottom and near the back). I carefully measured, and determined that I needed a drain hose no less than 10.0 ft.

The drain port on the Haier HLP24E portable washer is 1.0" O.D. (1. inch outer diameter), so the drain hose must have a connector that is 1.0" I.D. (1.0 inch inner diameter). The Frigidaire 154225602 (the "Electrolux 154225602" as per the packaging) Drain Hose has a 1.0" I.D. at both the 90-degree connector and at the straight connector. I connected the 90-degree connector to my washer and routed the hose around the back and then over to my sink.

The hardest part of finding a drain hose that would work for my new washer and kitchen layout was that every website that I was able to find that sells drain hoses (including Amazon) does not, in the vast majority of cases, list the inner diameter of the hose connections and the overall length of the hose. It took me days of searching until I found that the Frigidaire 154225602 (aka. the "Electrolux 154225602") fits the Haier HLP24E portable washer, and is 10 ft long instead of the OEM hose which was 5 ft long.

One thing that is nice about this hose for portable clothes washers or portable dishwashers is that it is transparent, so you can see the water level inside. That makes disconnecting it from your sink easier to do without spilling any water on the floor, because you can see exactly where the water level is inside the hose while you are relocating the hose after using the washer.

The washer itself is the nicest washer I have used in 36 years. Literally. There is no agitator inside, so there is actually quite a bit of room inside for laundry. I am 6'1" and have a larger-than average frame, so my articles of clothing are larger than average as well. But I can just fit 7 days of my "lights" in one load, and 7 days of my "darks" in a second load. That is similar to the capacity of traditional full-size washers with the agitator.

All of the controls are digital, allowing the engineers to be able to design very intelligent steps in the wash cycles. I use the "Heavy Duty" cycle, because the water in my town is hard (full of minerals) and therefore clothes don't rinse free of detergent very well unless you use warm or hot water to dissolve the soap and then later use a second rinse cycle. One extra-nice feature is that as the washer is filling with water each time, it repeatedly spins the wash basket a little, to get the clothes at the sides equally wet. That wasn't a feature in the previous washers I've used.

The wash basket also contains two lint traps which work very well. I've used too many washers without lint traps; those washers leave debris on your linens, essentially requiring you to then run them through a dryer to remove the lint. In contrast, the lint traps in the Haier HLP24E do such a good job that I don't need to use a dryer to remove lint, allowing me to hang-dry all of my laundry on two laundry racks that I have in my apartment. Just keep at least one or two windows open 1 inch or a half an inch, and the washer gets the clothes so dry that 24 to 36 hours later, all of my laundry is completely dry. That saves me a lot of money by not having to use the dryer each week, it saves me hours of each weekend, and my clothes last a lot longer too and never shrink.
