LG CordZero A9 Ultimate Vacuum Review

The LG CordZero A9 has an okay build quality. It's mostly made of plastic with a metal wand and rubber grips. The floor and carpet nozzles also have a small rubber wheel on the bottom. This design seems pretty sturdy, but the clear plastic dirt compartment could be damaged if it's dropped. While the vacuum itself is intuitive to assemble, the charging rack is more complicated, and you may need to look at the instructions to assemble or reconfigure it.

This vacuum is difficult to maintain. Several parts need maintenance, but each part is easy to access.

• Dirt compartment: To remove this part, you need to remove the battery first. Press the button at the bottom of the bin, then grab and twist the cyclone filter counter-clockwise to remove it. Since it's small, you need to empty this part regularly and clean its insides with the combination tool.
• Cyclone filter: You can remove this part once you've removed the dirt compartment. It should be cleaned under water, then allowed to dry.
• Exhaust filter: This part can be turned counter-clockwise to remove it. It should be cleaned with a brush or running water at least once a month.
• Pre-filter: Once you've removed the exhaust filter, you can pull out the pre-filter. You can clean it by using a brush or running it under water at least once a month.
• Power Carpet Nozzle and the Power Floor Nozzle: Both nozzles have the same cleaning instructions. To remove this part, you need to use a flat-blade screwdriver or coin to open the single cover lock. After this, you can rotate the brush cover upwards and pull the brush out. It should be checked before each use and cleaned if needed. You can use the crevice tool on the vacuum to clean it. You can also wipe the remaining debris off of it with a wet cloth.
• Power Punch Nozzle: You can turn this part upside down in order to access its brushroll. You can use the vacuum with the crevice tool to clean it. You can also pass a wet cloth over it to clear the remaining debris.

You must fully air dry any part that's washed with water before using it again. Don't dry the filters in direct sunlight. If you want a stick vacuum that's easier to maintain, check out the Roborock H6 Adapt.

The LG CordZero A9 has decently-low recurring costs.

• Filters: While the filters shouldn't need to be replaced if well-maintained, you can purchase the HEPA exhaust filter from the manufacturer's website, if necessary.
• Pre-filter: Even though the pre-filter is washable, it also needs to be replaced over time. However, the manufacturer doesn't provide a specific timeline for when it should be replaced. Luckily, you can purchase a Vacuum Filter Kit which contains one pre-filter, one cyclone, and one exhaust filter from the manufacturer's website.

The LG CordZero A9 is alright to store. The wall rack station can hold your vacuum when not in use. You can also reconfigure this rack station in three different ways to better suit your space: it can be wall-mounted, used as a stand, or placed so it's low on the ground. This rack station can also store three additional tools, but it's not enough for all of its included tools and brushes. Unlike the Dyson V15 Detect, it doesn't come with a wand clip to hold some tools on the vacuum itself.

The LG CordZero A9 has a reasonably-sized dirt compartment. It's small and needs to be emptied fairly frequently. On the upside, there's a max fill line to let you know when the compartment's full.

The LG CordZero A9 is a cordless vacuum, which has an unlimited range as long as you have battery life remaining and room left in its dirt compartment.

This vacuum is very portable. It's lightweight and doesn't feel very heavy in your hand. It also has a carrying handle to make it easier to take with you from one room to another.

The LG CordZero A9 has a good battery performance. It comes with two batteries, which allows you to use one battery while charging the other one. One battery has a minimum battery life of about eight minutes when using its 'TURBO' mode with its wand and Power Carpet Nozzle. However, you can extend its battery life to over 35 minutes by using its 'Normal' mode with its wand and Power Carpet Nozzle. You can double its total runtime by swapping out the battery for a fully charged one. This vacuum also has three white LED lights that gradually turn off to indicate when its battery level is running low.

The LG A9 comes with a few quality of life features. There are three easy-to-reach buttons on the top of its handles which control its power levels. The '+' button lets you switch between three modes increasing in power: 'Standard/Normal', 'Power', and 'TURBO', which you activate by pressing and holding this button. The '-' button switches between power levels in reverse, so you can lower its suction. Finally, there's an easy on/off button located above these two buttons. However, if you want to adjust the vacuum to different surface types, you have to physically change the head with either the Power Floor Nozzle or Power Carpet Nozzle.

The LG A9 Ultimate comes with a few tools and brushes. While it doesn't come with a turbo brush, the Power Punch Nozzle can be used for sheets, bedding, and other surfaces to help remove pet hair. This brush also acts as an upholstery tool for cleaning fabric-clad furniture. This model comes with a Power Carpet Nozzle too, which allows the vacuum to adjust to carpet, as well as a 2-in-1 brush/crevice attachment so that you can clean hard-to-reach areas.

You can use the LG CordZero A9 as a stick vacuum or reconfigure it into a handheld by detaching its wand.

The LG CordZero A9 has a fantastic performance on bare floors. It can pick up pet hair as well as small and large debris without an issue. Its performance also stays consistent, even as the dirt compartment fills up.

The LG CordZero A9 has a very good performance on low-pile carpet. It can pick up pet hair and a good amount of large debris like sand. However, it struggles a bit more with smaller debris such as baking soda.

The LG CordZero A9 has a good performance on high-pile carpet. While it easily picks up pet hair, small and large debris is a little more challenging for this vacuum. There's a small decline in performance when cleaning small debris when the dirt compartment is over 70% full.

The LG CordZero A9 has good maneuverability. It's lightweight, and swapping attachments or changing configurations is simple. However, it can be annoying to switch between the floor and carpet attachment. You also need to crouch down low to reach all the way underneath couches or tables and it can get stuck on rug tassels. There are a lot of attachments to manage, but luckily, the storage rack holds most tools.

This vacuum doesn't have any automation features.
