I was so looking forward to using the Lupe vacuum cleaner. However, I was disappointed with it for multiple reasons. The design of the vacuum head does generate better suction, which also create more drag on the carpet surface and requires more effort to push when vacuuming. On several occasions, the brush turned itself off while I was vacuuming the carpet and required me to have to turn it back on. The design of the vacuum also did not allow me to reach under the bed and other furniture as I was able to do with another wan-designed vacuum. Considering the high price for this vacuum, more than $800-US, I'm not satisfied with this purchase and will seek a refund. This is an additional review comment regarding Lupe Technology return policy. Before buying, be aware that the buyer is responsible for the cost to ship the product back to the company. Also, the delivery cost, which was "free" when the vacuum was purchased will be deducted from the refund. In other words, you will incur two shipping costs when you return the product. "The cost of return is the sole cost of the person returning the item." "Shipping costs are non-refundable. If you receive a refund, any delivery costs will be deducted from your refund."
