Black Friday offers are calling, but I don't know which to go for.
30C has the boundary strips, 15c has higher suction. Given we have carpet in some rooms, I'm thinking higher suction is a useful thing., but what about the boundary strips?
Do you use them, if so what for? Are they a permanent "thou shalt not pass" or could I put them round the Christmas tree, or more likely latest Lego creation I can't be bothered to tidy away before sending thr bot out.
