The Powermax TDM 100s is a treadmill with a unique feature of jumping wheels. Which is wheel as they are with treadmills but with springs. Which is supposed to dampen the impact more.
Meaning while running on this 2HP motor your knees will be more safe.
Apart from this there are some variation of tdm100s which is TDM 100 (without the jumping wheels), TDM 100M (Massager, situp bracket).
I do not think you will need pay extra for the Powermax TDM 100M version.
Takes around 5ft length and 2.5ft width.
