I.m looking for one that is both lightweight and effective. Have tried electronic sweepers but not really that effective. I tried out a Dyson one in shop, a stick one, but it was too heavy at 4 pounds or kilos, whatever it was because the weight was all at the top. I didn't want to have to install a dock either. It,s the carrying and lifting that,s a strain. Am stuck in bed with virus and dust getting worse.
