The ILIFE A4s Pro is a budget-friendly robot vacuum. It offers an excellent battery performance and comes with an electrowall, which is a small physical block that acts as a boundary marker. However, it really struggles on all surface types as it delivers a mediocre performance on bare floors and does an even worse job on carpet. Pet hair is especially tricky for it as hair can get caught in the brushroll or intake opening. It also requires a lot of regular maintenance and a few parts need to be replaced over time. Still, if you're on a tight budget and need a robot vacuum to clean bare floors, it's an alright option.

It does a significantly better job picking up small debris though. Still, this vacuum has a lot of parts that need regular maintenance and replacement over time.
The ILIFE A4s Pro is inadequate for low-pile carpet. It has trouble picking up small and large debris while pet hair can cling to its brushroll and intake opening rather than ending up in the dirt compartment. Although it's decently well-built, this vacuum also requires a lot of regular maintenance and has a few parts that need to be replaced over time.

The ILIFE A4s Pro has decent build quality. It's made of hard plastic with a thin rubber bumper, which makes it feel sturdy. Its three wheels are also made of rubber. It requires little assembly right out-of-the-box, as its side brushes are already preinstalled. Unfortunately, the dirt compartment feels a bit more flimsy and could crack if dropped.
The ILIFE A4s Pro is hard to maintain as there are a lot of parts that need maintenance. On the upside, most parts are very easy to access.
If you wash any part with water, it must be air-dried before using them again. The dustbin, pre-filter, and foam filter are the only parts that can be washed under water.
It has quite a few recurring costs. There's also a discrepancy in reported time frames between the manufacturer's website and the manual and we report the manual's time frame. Some parts don't have reported replacement times, so we use the replacement intervals established by comparable robot vacuums.
If you need replacement parts, you can purchase them from the manufacturer's website.
The ILIFE A4s Pro is very easy to store. It can self-dock onto its charging station or you can plug the power cord into the robot directly.
The ILIFE A4s Pro's dirt compartment is acceptable. It's slightly larger than the eufy RoboVac 11S but it still needs frequent emptying. The dirt compartment is clear so you can see when it needs to be emptied, but it doesn't have a sensor to tell you when it's full.
The ILIFE A4s Pro has an unlimited range as long as it still has battery life remaining and room left in its dirt compartment. However, it can't go up or down stairs.
The ILIFE A4s Pro is very portable. It isn't very heavy, and while it doesn't have a carrying handle, it's easy to take with you to another floor.
The LIFE A4s Pro has excellent battery performance. On its most powerful 'MAX' mode, it lasts for under 50 minutes. However, if used on its more power-conservative 'Auto Cleaning' mode, it can last for around 110 minutes. Although it's advertised to take less than 300 minutes to fully charge, we measured over an hour less. Also, the vacuum has a battery indicator light that changes from green when cleaning to orange when it has a low battery, and red when there's a malfunction.
This vacuum has a couple of quality of life features. It has two power settings" 'Auto Cleaning', which is its default mode, and 'MAX'. Using the remote, you can also access different cleaning methods such as auto cleaning, edge cleaning, spot cleaning, or mini-room cleaning, which is suitable for smaller spaces. It also has an automatic 'Carpet Detection' feature, which increases its power when it detects thick carpets or harder-to-clean messes.

This vacuum has a disappointing performance on high-pile carpets. Pet hair sticks to the brushroll and intake opening rather than getting sucked up. It also struggles to pick up large debris like sand as well as finer debris like baking soda.
The ILIFE A4s Pro has just adequate maneuverability. It can get underneath couches and tables; however, it can get caught on electrical cords or stuck on tassels. Using its random pathing, it can clean an area well. It also has a 'Carpet Detect' feature that boosts its suction power on shaggy carpet.
The ILIFE A4s Pro has decent automation features. While it doesn't have a companion app, it comes with a remote control, so you don't even need an internet connection to use it. The remote allows you to adjust its power mode, set different cleaning modes, arrange a cleaning schedule time, and direct the vacuum by manually controlling it. The manufacturer also includes an electrowall which acts as a boundary marker and it sets an invisible barrier that the robot won't cross.
The ILIFE A4s Pro comes in one variant: 'Black'. You can see its label here. There's also a variant available called the ILIFE A4 Robot Vacuum Cleaner. This variant is advertised to use a less recent cleaning system and doesn't come with an electrowall. Due to these differences, this variant may not perform similarly to our test model.

The ILIFE A4s Pro is a budget-level vacuum. While many robot vacuums have trouble on carpet, this model struggles noticeably with pet hair, which clings to its parts rather than getting fully sucked up. It also uses a block-like boundary marker called an electrowall to keep the robot from accessing a certain area, which can be a bit limiting if you need to block out more space. On the upside, it offers an excellent battery life. Check out our recommendations for the best robot vacuums for pet hair, the best robot vacuums for carpet, and the best robot vacuums.
The ONSON GOOVI F007 Robot Vacuum and the ILIFE A4s Pro are similarly performing vacuums but you may prefer one over the other, depending on your needs. The ONSON performs better on low and high-pile carpet and its battery performance is better too. However, the ILIFE is better on bare floors and has fewer recurring costs.
