Canisters can be a bit of a problem to decide on.

The way canisters are marketed and priced, some times
it will pay to stay with an upright.

An example of what I mean is if you look at the uprights
that are priced around $300, you will find that they
have about twice the airflow of the canisters
in that same price range.

It isn't until you get into the $500-$1200 price range that
you see equality in performance.

If you really can't afford to spend more than $300 then I
might even suggest an upright and seperate portable canister instead.

If you really need a canister and can't see spending more than $300,
the Fuller Brush canister is an excellent way to go.

The best canisters out on the market now are made by SEBO.

SEBO canisters among the highest airflow vacuums available,
the best filtering systems, (99.97% @ .3 microns).
They also have best warranties (5 years on entire vacuum cleaner),
and they are the most ergonomic in design.

If your home is mostly carpeted, or at least 50% carpeting and
you are looking for a canister that works great for both carpets and barefloors
then we recommend the SEBO K3.

If you have mostly bare floors and maybe throw rugs or
very little carpet then we recommend the SEBO K2.
