From what I can see GTech first offerings were the cordless sweepers - a quick and easy way to sweep up crumbs between vacuuming.
At least GTech have realised their machines capability and added an extra machine making other jobs achievable and far easier.
Easier because one didnt have to drag out a heavy vac, plug it in and have the restrictions of a power cord.
I think the evolution of the AR has come from those who have bought the sweeper and not used their regular vac very often after, a bit to the detriment of their carpets cleanliness.
Thing is because the SWV sweepers are so light and do a great job of surface cleaning I think once you have owned one dragging out a vac has become a bit of a pain for regular people. I know I feel that way myself.
I used to get the big vacs out everyday just to run around and pick up a few crumbs, cat hair and cat litter.
It does become a pain getting it out, unwinding the cord, pushing it around, winding the cord back up and putting it away.
My AirRam turns this 10 minute job into a 3 minute one with very little effort.
Where the AirRam has evolved from the SWV's is that they do pull dust and grit out of the carpet with the suction they also provide ontop of the surface litter brushing action.
If we really want to be critical of the AIRRam then the following points need to be taken into account about the Dyson.
1, the dyson was originally a handheld vac and the addition of the long tube and floorhead makes it a heavy vac to use due to its top heavy and high centre of gravity.
Gtechs AR gravity centre is lower and much easier to use.
2, dyson seem to spend alot of time bleating about its use on hardfloors yet they dont mention half as much of its performance on carpets if any. I wonder why?
3, Usage time, GTech wins there!
4, the AR's handle is easier to hold than the dysons. It means the user hasnt got the weight of most of it in their hands and the bulky unit in your hands may well restrict where you direct the cleaner in tight spaces around between beds and walls etc.
5, no cloud dust when emptying!
6, the AR's brushroll is better suited to carpet cleaning when all said and done.
7, the AR ram purpose designed. All dyson have done is add extras onto an unwieldy ready made design with little thought to the actual use.
At least GTech have realised their machines capability and added an extra machine making other jobs achievable and far easier.
I disagree the AR is only capable of floor cleaning. I have done the stairs with it, sofa cushions, car boots, car seats, bathroom mats, cat bedding.
Dyson has some serious competition out there, about time too.
