Handheld battery vacuums are typically smaller, portable version of the traditional vacuum cleaner, they come with their set of pros and cons. The most obvious con being that it is not a good solution for vacuuming large areas of your home but other issues are the batteries do last very long and also, very few companies have replacement parts for them. In the last few years, these stickvacs have become very popular but our store specializes in repairs, we repair everything we sell so we must make absolutely certain replacement parts are available. At this point in time, the battery technology is not great, Lithium mining is a terrible pollutant to our planet and disposing of failed batteries should NOT end up in landfills. We DO NOT recommend these units.
