Sirs, I have recently moved into an apartment and decided that an efficient cordless vacuum cleaner would best suit my requirements. I had never heard of Lupe Technology so when various searches brought your name to my attention , I decided to investigate further. I purchased direct from you within thirty minuets and I am delighted with the product. It is very obviously robust and very powerful. It is indistinguishable from a normal quality corded cleaner power wise . The versatility of the tools show that Lupe have moved up into another level of technology . Excellent product and a pleasure to review.
