Hi, sebo, for price and general effectivness, however, I invested in a Rainbow E - series some years ago ( £1600 ) when I got mine, doesn,t feel like its doing anything but the crap it pulls out is unreal, H2O vac off of QVC similar idea coupled with a power-vac attachment might have good results, but most of the time I use power vac attachment with downer on my ninja, no reason why it can't be used with TMs either. read most of the posts on this subject, sebo 36, seems most popular, and they do go on and on with minimal problems, I've used them for 18 years ( I have 4 ) only ever really change belts, drive spigots, filters and brushes, motors seem indistructible.
