Mike,
not sure what you mean " which one do I reccomend " if you mean the encap product itself , I
was using an ecap product from Bray chemicals , not sure were you will get it from now though,
M. halliday may be able to put you in the picture regarding bray, I am at presently using cimex, own encap product, available from truvox, to be honest I found the former a little better as it did foam easier. i do believe prochem have just put one onto the market, not tried yet , seems a little pricy to me
but if any one wants to send me a sample , i will try

if you are reffering to the cimex machine go for the cyclone 48 , a little heavier but does cover more tasks Cyclone 48
Suitable for commercial and industrial applications, Cyclone scrubber/polishers are multi-purpose machines suitable for cleaning and polishing virtually every type of flooring from concrete to wood, vinyl to carpet, rubber to tiles and a wide range of other floor types.
At the heart of the Cyclone machine is the famous Cimex triple-brush cleaning mechanism which incorporates a contra-rotating planetary drive disc. This gives a vigorous action that cleans in all directions with the brushes cleaning deep into the grouting of tiles floors, around the contours of rubber studded non-slip floors or into the pile of carpets.
Functional but highly important design features of the Cyclone machines are the non-marking wheels, a belt drive for exceptionally quiet operation, and the availability of a spray version for carpet bonnet mopping. An extensive range of brushes is available, covering all tasks from shampooing carpets or scarifying to polishing of hard floors Geoff
