Do tell, which models are these? Everything I've seen shows the separation/filtration media somewhere between horiz. and vert. Still, because it's a canister, there is no issue that compares to the atempted use of a bagless upright laid flat.

One thing to think about will the DC18 be as slim as the DC03? What I mean is the DC03 lying flat on the floor was very slim and could get under beds etc with ease! Thats one of the many things I liked about the DC03! I don't think the DC18 will! I will be easier to clean along skirting without knocking radiator pipes etc as the head sticks out either side of the cleaner!
 
With a 1200 watt motor probably the same power and performance as the DC15!?
 
I think the Dyson Engineers should have gone for the 6kg mark on weight!
 
 
From what I've observed about bagless machines (until I stand corrected),
 
Yeah, yeah. Ok,  I stand corrected as I knew I would. But be honest: how seriously do you take a robotic vacuum-especially one that is not yet available in the USA? Believing what one sees on the internet is tantamount to believing what one sees on infomercials. I really didn't mean to bring canisters into the mix with my previous post. My point was that there is no bagless upright (Dyson or other) that will fit under the average person's bed (where most of the dust mites & their byproducts are found).

Let me see apart from the DC06 Robotic all Dyson Cylinders/Cansiter bin are at an angle for one and they work perfectly!  
 
I've owned a DC03 and it worked very well flat on the floor, the dual cyclone system carried on working as it did when in the upright or at an angle when in use or flat on the floor!
 
When it went under my bed ok with no problems and under low furniture with ease!  It would even go under the bed I have now but other Dyson will not without using the tool attachments!
 
Dyson would have checked and tested the cyclone technology works at an angle or completely flat on the floor!  After all gravity pulls things down!!

It should also be noted that the Dyson DC07 has inverted high-efficiency cyclones: where the dust is whirled out of the TOP of the cyclone (unlike DC14 & 15, where the cyclones point down).
 
Filters do not appear to require extra cleaning.

One thing Dyson has dropped on this model is the metal soleplate it had on the DC15 is not on the DC18 this time!  There is a rubber stripe that runs the full length of teh soleplate behind the brush roll opening!
