Like other vacuum cleaners, the cordless models come in various shapes and sizes. Each has their own advantages and disadvantages. But, regardless of the size, the ingenious of the design really lies on the innovation that literally frees you from being restricted and tied to your electric wall socket.
The small size and lightweight designs of portable cordless vacuum cleaners enable you to clean practically anywhere. The cordless technology has allowed you inconceivable mobility when it comes to your vacuuming. With small cordless vacuum cleaners, you can easily bring the unit and clean your carpets then afterwards vacuum the bedroom, the kitchen floor, bring it to the basement, up the attic and even vacuum on the roof.
Also, without the troublesome chord, it is a lot safer now to vacuum on a ladder or a scaffold. Likewise, you can reach out-of-the-way areas that were not possible before with cordless models.
Although the portable ones have already powerful suction capabilities, some still look for larger cleaners that have more power but offer the same convenience of handheld ones. This is probably the reason why manufactures created the larger upright cordless vacuum cleaners, which are almost like the full-sized vacuum cleaners but are rechargeable and more lightweight.
These upright cordless vacuum cleaners will allow you to clean from room to room without worrying of running out of cord. Since these are upright, they are more suitable to be used on floors than the smaller handheld ones.
Usually, these units also come with various extension tubes and attachments similar to regular vacuum cleaners. It was Hitachi Ltd. that first released a large cordless vacuum cleaner with wheels sometime in the early 2000s, this according to The Nikkei Weekly. The earlier Hitachi version of large cordless vacuum cleaners had a total of 25 minutes run time after the internal batteries were charged for six hours. Today some large cordless vacuum cleaners can continuously clean for 60 minutes after 2 hours of charging.
Aside from these two types, there are a few mini vacuum cleaners that run on regular batteries. These types are usually small enough to get into very small gaps like the spaces between your computer keys. There are even models that can power up by plugging them into a computer's USB port.
Other useful and money saving features of most cordless vacuum cleaners are bagless operations, capable of reversing air direction and wet/dry capabilities.
However, given the diversity of models, sizes, power and designs, it is always best to choose the type and model that fit your specific needs.
