Thanks Redman for mentioning Argos, which store enabled me to look at customers' reviews.
I now have a few reservations and I'm now not at all sure. At a quick count, only 12 persons gave 5 stars out of 30. Although a few said 'excellent' and even 'brilliant', several said not a good hose connection, one said the hose split and it was even mentioned to keep the hose in the shadr which makes me think it could become brittle or even rot.
Also, if it turned out not to be a good buy, my husband would say "I told you so ............." Many thnx.
