Like you, brissles, I have a GTech Mkll upstairs and the same model for downstairs. I also have an Oreck upright hoover which is brilliant but, since buying the Gtechs, I havenāt used it. I also have the GTech multi tool for the stairs and car.
I keep getting offers from GTech on their gardening tools but, as I donāt have a lawn having opted to have the garden bloc paved, I ignore those.
My ex bought a Dyson vacuum cleaner but got rid of it because it weighed a tonne, which was great (not) when carrying it upstairs, and it didnāt do as good a job as the hoover he already had.
So, as you said .... Dyson, with their high priced gadgets, can go swivel.
