What People Are Saying

Rated 2 out of 5 by from Drying Time - Once happy now not so much! We have had this for about 2 years now and knew the drying time was going to be longer when compared to traditional washer / dryer. It was working just fine and then about 6 months ago the drying time has been horrible. I mean after 5 hours clothes are still damp. We have added "more" dry time, reduced the load size (which by the way was fine when we first purchased machine), and have cleaned the trap. Today I sent support an email and am hoping they have a resolution. We have it on a pedestal as well. On the upside, this machine does wash and spin clothes dry. I wished the warranty was longer than 1 year. One other thing is that the spin cycle is so high that jeans come out with semi-permanent wrinkles - so, I spend more time ironing - I have taken them out before drying to shake them out and they are still really wrinkled. Those I definitely take out after first drying cycle, while they are damp, so I can flatten them out as they dry. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from This machine is basically perfect. Got this washer back in November 2016. Solid, sturdy construction were a good indication of it's continued performance. The cycles are abundant and washing and drying is premium as well as its economy of power, water, and space. I hooked the drain up low to the ground on a plugged drain pad over a carpet and connected the drain and water connections under an apartment bathroom sink. In my case I had to add a separate drain trap and autovent to get as close to code as possible. This might be considered advanced for some but it was fun for me and made this the ideal project for an apartment renter with no laundry inside. Luckily I also have a cool resident manager. The one slight gripe I have is that there is no way to turn off the chime alert music at the end of the cycle. I can sleep right through the gentle drying cycle but the chime wakes me up for a minute. I heard you can cover the audio holes or something but lately I've been washing while away from home so it's no big dealzies. [This review was collected as part of a promotion.]

Rated 3 out of 5 by from Good Machine but some quirks It's a good washer dryer for compact spaces and needs no venting. Three things I wish I knew before I had bought this machine: 1- Significantly long drying times, 2:30-4:00 hours, depending on the type of clothes 2- Dryer capacity is less than Washing capacity, which means that if you do a full wash load you have to remove about a third of it to dry it 3- There is no easy to access lint filter and the manual instructs you to clear up the lint on the rubber grommet around the door, you have to do this every time you dry clothes, else the lint will be in your next wash. There is a lint filter that can get clogged if you don't do the afrorementioned, when it gets clogged the machine detects this and will tell you to remove it and clean it out with a toothbrush. The machine takes some getting used to, the long times. You want to set it at night or during the day with a delay so clothes are done when you get up or get home from work.

Rated 4 out of 5 by from Convenience is key The biggest and best thing about this machine is the fact that it rolls right into the drying mode if you want it to. AND it's perfect for linen closet space. We are still trying to learn it and all of the features it has! There are a lot!! The only downside we've experienced is that it does emit a good amount of heat. If you're looking to put it in an area that is high traffic, just know it will be a little warmer than usual.

Rated 1 out of 5 by from Clothes smell, are fried, and huge time killer Not impressed. I loved the idea of not having to switch the load and the space saving, but after dealing with huge learning curve on how to use the darn thing, the clothes stink like they are burned and don't smell fresh. I have mostly new clothes for my newborn and they were wrinkled and smelled so bad. the cycle time to wash/dry one load is sooo long, shortest setting to complete a full wash and dry cycle I learned is about 3 1/2 hours.

Rated 5 out of 5 by from Incredibly awesome machine.... Throw clothes in set the timer for when electricity is at the lowest price and presto it does it all including drying clothes... Brilliant idea. Ideal for basement installation. Or laundry room. Probably one of the best inventions for wash and dry in a single step. [This review was collected as part of a promotion.]
