Can anyone recommend me a stick vacuum cleaner for flagstone floors? I moved house last Christmas and thought my hardwood and flagstone would be fine with sweeping and a dustpan and brush. It's pointless though - there are deep grooves in the side of each flagstone where the dust gathers and brushing it just doesn't lift from the grove.
I need a good downstairs hoover - preferably stick (weakling wrists) that will cope well with flagstones.
Any recommendations?
