Mike - I'm a little wary of going second-hand because I wouldn't know the machines history, whether it's been used without defoamer/knocked about etc.
John - Not all of the apartments have lifts but I'm quite physically capable so not too concerned about that. With regards heat I do see it as a strong bonus as i often opt for conventional cleaning detergents but I'm also familiar enough now with detergent free cleaning that I could go down that route.
The enforcer will stairclimb , i would describe myself as medium strength , i can haul it upstairs , if your strong u can do it easy enough , its not great for the back though to be hauling any full size machine a lot . I since got an alltec express for stair jobs ... but there are disadvantages tot he smaller machines also if you have a lot of ground to cover the bigger machines will speed things up in terms of water capacity , often more power , better heat .
The last sentence you wrote there ... infers that " detergent free " performs better if you dont have heat ... really there is no correlation that supports that .
Sounds like the usual cleantalk sales pitch ... look at a " detergent free " product sy SPM ? its made up of just phosphate or sodium carbonate ...and some percarbonate bleach .... those form the basis of most detergent products u care to mention ... but the detergent products will have a few other ingredients aded to enhance performance .
So by removing the performance enhancing components are they left with something that performs better in colder temps ...no . it makes no difference .
Look at the big money companies like proctor and gamble , they formulated a cold water laundry product (tide cold water ) ...if you look into it i releys heavily on a boosting the enzyme content , and adding many more chemical components to gain acceptable performance at low temps .
If a product like spm or microsplitter ( another nonsence word ) worked better at low temps .... P&G could have saved themselves millions by just removing a few ingredients from regular tide ... to end up with just sodiyum carbonate or phosphate like the so called Microsplitters .
Its all nonsence ... cleantalk sales team will always push those products on discussion threads with all sorts of claims ... because ... they are really cheap to make ! high profit .... same with mmpower ... someone says nitro blew me away ... they will still say ...could have used mm power ...again , cheap and unfussy to prepare , no distilled water or additives needed just fill the conc into containers at back of the unit with a hose pipe . $$$
