I have actually been flirting with getting a new vacuum for some months. I had looked at the Dyson line, but balked, frankly, at the price point. Ye gods and little fishes…I couldn’t get past it.But thanks to imitation being the sincerest form of flattery, there are a great many vacuum manufacturers who are incorporating Dyson engineering or design elements into less pricey alternatives. My previous Hoover (model U5456-900) dates back to 1999, and with the exception of an indicator light that had died within a month of owning it, I have had no problems. Never affected the way the unit worked as far as I can tell. I was more than willing to give a Hoover cyclonic a try.The UH72400 is a Windtunnel 3 with a bagless cyclonic canister. It has a smaller foot print than my old Hoover, and is quieter. This led me to wonder if it was cleaning as well, but no… it works just great. You do empty out the canister far more often than you change out a bag, but this is a little thing.:Accessories: The UH72400 has exactly two accessories, a combination upholstery and crevice tool and the hose/handle. The hose handle combination looks like it was taken directly out of the Dyson playbook, except that the machine end of the hose must be manually switched into a suction port. The working end can be released and pulled out of the body (as just a short handle, or longer tube) to suck up small debris, but the full handle is not a telescoping variety. It turns out to be six inches shorter than the full accessory handle on my old Hoover, and I could not reach cobwebs in ceiling corners or curtain rods as easily.The old accessories fit, though, so I could extend my reach, but still – no where to conveniently store them on the machine, even if you had any you could add on.:Canister: The canister has a HEPA filter and a washable filter. I’ve been hand washing my old vacuums filters for years – just be sure they are bone dry before you reinsert them! The HEPA filter you don’t wash, just knock the excess debris from it.One button empties the canister, but unless the contents are heavy, it will need a little jiggle to flip open. =Fair warning= Do NOT shake the canister empty with a twisting motion to get debris out! When I did this, the canister/filter assembly neatly detached itself from the twist on top and handle and fell into the garbage can in a cloud of vacuum dust. Shake it up and down, perhaps a little side to side (carefully), but no twisting. That was a mess. They could probably stand to put a small friction point where the canister connects to the top to make it even slightly less easy to pop off unexpectedly during emptying.:Cleaning head: It’s surprising that the Windtunnel hasn’t changed much in 14 years. The rotary brush is more or less the same, but there are some differences. The new unit is a lower profile, and rides low, easier to reach under furniture, or under cabinet doors. Unlike my old one, it does not have an adjustable height, but is supposed to auto adjust. Happily, this means it also flings less cat litter around when vacuuming stray litter from around the cat area, but I have no idea how well this will work on a lose pile carpet (like shag… SO 70′s but still can be found in the wild). Instead of a foot switch, you just pres down the entire cleaning head. The rotary brush engages, and off you go.:Operation: The unit has an electronic on/off pushbutton, which means it doesn’t stay depressed once pushed on, and the only way to tell if it’s on or off is if the motor turns on when you plug it in. On the flip side, because the rotary brushes in the Windtunnel head do not engage while the vacuum is in the fully upright position, you aren’t likely to accidentally suck up the cat or anything. The maneuverability is a vast improvement over the old Hoover, and twisting the handle during operation easily changes course.The unit is less cumbersome, and a bit lighter than the old one, so I could actually lift it and use it on stair treads, dog beds, and seat cushions.:Bottom line: I ran my old Hoover over my rugs, vinyl and hardwood flooring Saturday. Four days later I ran the new Hoover Windtunnel Air over the same surfaces and got an impressive (or depressing, depending how you look at it!) amount of fine dirt and debris in the canister. Either I generate that much dust and dirt in four days, or my old vac wasn’t cleaning as well as I thought.My old Hoover had a two year warranty and needed two belt replacements and had a broken LED in 14 years. No major issues. The Windtunnel Air comes with a 5 year warranty, which I naturally haven’t needed to test out as yet, but my past experiences with Hoover have been positive.At this price, if you can live with the hose length issues, this is a very decent substitute for one of the more expensive cyclonics which are 2-3 times the price.
