I have owned the Maytag mvwp575gw for over 18 months now.
I have owned the Maytag mvwp575gw for over 18 months now in my kid and pet friendly home. I have the service manual for the actual commercial version, which is similar. To the best of my knowledge, the following information may be helpful to you.
This washer uses about 14 gallons for the "Normal" Eco wash cycle. This cycle has three short spray rinses, which use an additional small amount of water. This cycle works great for smaller loads and quick washes for everything except delicates. The only real quirk is "hot" for this cycle is more like warm. There are various ways to add hot tap when needed. If you select any "Options" this cycle becomes a full tub wash and full tub rinse.
All of the main cycles (Bulky, Delicates, Mixed, and Powerwash) fill with a full tub of water which is about 22 gallons. On the commercial version used in laundry mats, you will get 3 more gallons for the bulky cycle. Honestly, I can tell on mine if it adds more water or not. I have never taken a yard stick to measure it. The main cycle has a full tub rinse (about another 22 gallons). The main wash cycles have tap hot. A full load is clothes loosely placed around the agitator until the tub is about 3/4 full.
All rinses are cold.
Yes, this is a vmw design. It is not the Maytag us older folks remember. However, this is the ONLY Maytag top load I would purchase. This Maytag "commercial residential" model should not be confused with Maytag/Whirlpool's other "commercial technology" models sold in the big box stores. It has an upgraded 1/2 hp motor, 7-rib vs. 5-rib belt, 60 watt vs. 50 or less watt capacitor, premium bearings, dual agitator vs. powerwash agitator, comes with premium hoses, and more. The vmw design plus the front panel and bottom access does make it easy to work on and repair vs. even the SQ.
This washer is my first overall choice for cleaning performance for its dual agitator. Not only does the agitator top and bottom move independently but the whole agitator moves separately from the tub. It is the real magic of this washer, and why I like it so much!!! I was shocked with the amount of dirt that came out of a comforter I had been regularly washing in the old LG front load I had. The Maytag actually moved all surfaces of the comforter through and around the water instead of trying to wash folded up. It comes with a five year parts and labor warranty.
The TC5000 would be my top overall choice. It does not have a dual agitator but at least the agitator and tub move separately so the wash action is still good. The half load selections do include delicates and the wash temperature is selectable (can have tap hot without manually adding it). It is built to be more durable. The suspension design is better. With that said, I haven't had any real issues with the Maytag when washing like items--a typical load of jeans, towels, permanent press, etc. I don't think the Maytag will handle uneven loads as well like pet beds or bed pillows (those shouldn't really be washed in a top load anyway, but...).
This SQ TC5000 model is not the old SQ though. It has TWO model-specific control boards and no water level control. Also, this is likely a time limited model that will be discontinued at the end of 2020. For that reason, it *may* be difficult to find parts for. I am curious to see what SQ does because their TR series works best for people who need to wash office attire. The TC5000 is what works better for people who have technical trade jobs, pets, or kids. The Maytag has ONE control board, but I don't think it will be as hard to find later because it is the same part used in their other real commercial models. In the end, the bearings and seals will probably be the reason someone replaces either of those models as this is not something the average consumer will repair themselves. I am not sure the SQ is any better than Maytag in that regard for THESE two models.
The SQ comes with a THREE year parts and labor warranty. The SQ costs more and can be a little or a lot depending on where you live. If it's not much difference, I would go with the SQ TC5000wn. I do think it will have fewer repairs and last a little longer...maybe 15 years w/o major repairs? I am going to take an educated guess and say the Maytag will probably last ten years though you may have some minor repairs like the actuator. Any lemon with either model should show up within that warranty period. If a matching set is important, there is no justification I can see for paying more for the SQ dryer vs. the matching dryer for the Maytag. If the SQ isn't an option, I still think the Maytag mvwp575gw is the second best overall option.
Your best bet is to try and find an older rebuilt model especially if you have someone in your area that restores these.
One thing I have learned from reading these boards is some people trade out washers like many consumers do their cell phones. I can tell you I am not one of them nor am I in the sales/repair business. While I think many people have a lot of good knowledge that comes from that, I think some receive incentives for recommending one brand over another. Others have no budget concerns. So my viewpoint is from someone that paid full price and plans to keep the machine until it dies. I can do minor repairs but repairs I cannot do myself would probably result in me sending any washer to the landfill (it's just not cost effective).
Hope that helps.
