Vacuum Cleaners Discussions

We just moved into an apartment with “engineered hardwood” floors. We’ve been using our Sebo canister, but I have to carry it and navigate backwards and try not to trip over the cord. So I am considering a stick cordless. But, never having seen or used one before, I’d like to find a deal on ebay and try one out. But I’d say 75% or more of the vacs there are being sold without chargers, and finding replacement chargers is no easy task. So I’m wondering if any charger with matching electrical specs will work, or if the charger cords have a special plug on them or something? Thanks in advance.
