If you're looking for an even lighter portable cordless stick/handheld vacuum, consider the Dyson Micro 1.5kg.
It comes with a wide variety of attachments, like a miniature turbo brush for cleaning upholstered surfaces and a crevice tool for cleaning tight spots. You can easily remove its wand to use it in a handheld configuration to clean hard-to-reach areas. This cordless vacuum is lighter than many other Dyson vacuums, letting you maneuver it in tight spaces fairly easily.

Best Lightweight Stick Vacuum: Dyson V8 Animal.Get the Shark if you want a handheld vacuum that offers superior overall performance and has a larger dustbin, but consider the Wyze if you want longer battery life and an allergen-trapping HEPA filter. Unfortunately, its dustbin is very small and consequently needs frequent emptying. It feels well-built and doesn't have very many parts that need regular cleaning. Performance on low and high-pile carpet is very good, though you may need to make another pass to fully clean very fine debris. However, running it in its 'Max' power mode drops its battery life to roughly 10 minutes. It offers superior battery performance, as you can expect a maximum of half an hour of runtime when using it in its default suction power mode.
It comes with a few more tools and accessories, including an extension hose to help you clean hard-to-reach areas as well as a dedicated upholstery tool. Unlike the Shark UltraCyclone Pet Pro+, it struggles with sucking up very bulky debris and doesn't come with a miniature turbo brush, but it's notably smaller and lighter. If you want a handheld vacuum that's even more portable, check out the Wyze Handheld Vacuum. More Portable Alternative: Wyze Handheld Vacuum.
Otherwise, its compact size, affordable price point, and strong performance make it one of the best vacuums under $100 that we've tested. It also lacks a HEPA filter, so it might not be the best choice if you suffer from serious allergies. You can't adjust its suction power either, which would help conserve battery life. Unfortunately, this vacuum's battery life is very short, as you can only expect roughly 10 minutes of runtime on a single charge. It comes with a crevice tool to deal with messes in tight corners, as well as a turbo brush attachment with a self-cleaning brushroll for easier cleaning of upholstered surfaces. This vacuum delivers remarkable performance on bare floors as well as low and high-pile carpet, easily cleaning pet hair and various types of solid debris. It feels well-built and has a simple design that incurs few recurring costs. This compact cordless vacuum can be easily carried around to spot-clean most hard-to-reach areas and is small enough to be stored in most cupboards or closets. Of all the handheld vacuum cleaners we've tested, the best lightweight vacuum is the Shark UltraCyclone Pet Pro+.
