Review on Dyson V10 Allergy Cordless Vacuum Cleaner by Mark Sharma

B-10 models and all with canisters parallel to the tube have design flaws compared to previous models with canisters perpendicular to the tube. On these models, debris and hair enter the canister through the outlet (rather than directly out of the tube). When you vacuum your hair, it constantly clogs. I can't imagine why Dyson did this as it's less efficient than the old style. It is also much more difficult to empty the canister. First you need to remove the hose. Then it is harder to open than the old design. If you're dealing with hair, you'll need to use your fingers to unclog the port. Although it sucks more than the previous models, it is neither more efficient nor better in my opinion. I prefer my old V-7. It may not clog when you're not vacuuming hair, but the inconvenience of emptying remains. I am very disappointed in this product and cannot understand why Dyson made these changes.
