May Not Be An Oil Painting, But My TT Isn't Too Shabby!
You can view snaps of my Hoover TT below. Not sure what the British version would be, but know it was an early model on both sides of the pond.
Yes, twin tubs do give good rinsing, but are not very water efficient unless one reuses the wash water several times, and or uses spray rinses only.
Twin tubs are indeed popular, as seen by the likes of Danby and others still producing them in one form or another. Also as often mentioned there is a commercial version sold by Unimac, used by car washes and hotels,motels, and others places with lots of small wash to do (shirts,napkins, mops, dish cloths and so forth).
Hoover TT Wash Time:
My repair/parts/service manual clearly states one should NOT exceed the max wash time on the TT, otherwise tangling will result.
Rinsing In The Spinner:
Have heard several methods, but our repair man and the owner's manual says one should fill the spin tub with enough water to cover the items in the basket, then let the spinner do it's thing. Whilst this causes tons of water to go spraying inside the spin tubs, it is very effective in rinsing. Others here have advised against this method and state it is better to slowly saturate the laundry then spin. IMHO the later seems to take too long in rinsing, but their we are, aren't we?
