Having been persuaded to venture into the field of robot vacuums it was with much interest that I set this going round the house! Especially enjoyed have the work done while I breakfasted! What was astounding was its efficiency and effectiveness! After following the instructions to vacuum 3 x before first use it was somewhat horrifying to see the mount of dust/dirt this picked up! So now I have clean carpets, putting "Rocky" round the house every couple of days with the option of choosing individual rooms or everywhere. It is duo nice not to have to manoeuvre a heavy dyson cleaner around behind me!! Thoroughly happy with this product!
