Are you looking for a new upright vacuum cleaner and have identified potentially the two new Hoover WindTunnel models -- the UH70400 and UH72400 -- however are unsure as to which to get? If so, then you are in the right place. Below, is a brief comparison guide that pin points both their differences and similarities amongst features & specifications to ultimately paint you a clear picture as to which vacuum can offer you what as well as which one best suits your cleaning preferences.

Which has the better cleaning suction & performance?

Both operate on a 11 amp motor & multi-cyclone system as well as the WindTunnel technology exclusive to Hoover which means they are bagless and also don't suffer with a loss of suction. However, the Steerable model actually offers a marginally greater suction capacity & hence cleaning performance due to it being fitted with the updated & re-confgiured "exclusive WindTunnel 3 technology". They also both have a brush roll switch that can be interchanged depending on the floor type you are on to allow for a more optimised clean as well as not to damage any hard-flooring. In all, both models are surprisingly powerful given their relative size & weight (along with the price, especially in comparison to many Dyson models) on all floor types for dust & debris (including pet hair).

Which is easiest to use/handle?

Firstly, both models are extremely lightweight -- with the Steerable weighing in at less than 14 lbs and the Bagless at just 12.6 lbs (making it in turn Hoover's lightest upright). However, although the Bagless is somewhat lighter, but because  the UH72400 has the integrated steerable technology at the base, this makes turning around awkward corners and angles easier  (saving you the hassle of a 3 point turn, dragging it back and forth) -- with the general navigation a much smoother & less rigid process. This is a bit of a subjective matter though, so you should try them out at your local vacuum store to get a better feel of each.

Which offers the best practical specifications? 

Both models have also been designed with practical cleaning use in mind -- the Steerable has a naturally low profile head to clean under furniture etc. whereas the Bagless has an integrated recliner which allows it to go all the way down to the floor, effectively carrying out the same job.

With the Bagless you have an automatic height adjustment mechanism, which doesn't feature on the steerable -- arguably this better suits certain individuals (either they are particularly tall or short) when operating the vacuum. 

They both share the same extensive hose length of 30 ft, but with the hose reach -- the Steerable is a little longer at 14 ft whereas the Bagless it is at 12 ft.

With the on-board accessories the Steerable just has a 2 in 1 tool which is basically a crevice tool & brush nozzle. The Bagless however has an array of attachments including the crevice tool, upholstery/dusting brush, 3 in 1 combination tool as well as a stair hose.

Further Information

With regards to warranty -- the steerable is covered with a 5 year warranty when bought new & with the bagless it is just a 2 year coverage plan.

They are also fitted with a easily maintainable HEPA filter system that prevents allergens & dust particles from being expelled into the air whilst vacuuming -- hence are safe to be used by allergy sufferers & asthmatics.

Conclusion: Which vacuum should you buy -- the UH70400 or UH72400?

Given the price of the two models are very similar around the $130 approximately -- I would personally opt for the Steerable given that it is a bit more powerful (although this is relatively marginal factor) is more agile and easier to use, as well as the practical features not being too dissimilar (they are both bagless, both have an extensive cleaning reach, they have the electronic brush roll -- it does get somewhat trumped in the on-board accessories but these can be simply purchased separately if I find that identify a particular need for them), but also a particularly big deal breaker is I know I get an extra three years on my warranty.
