Pool Cleaner Waterproof Ratings: IPX7 and IPX8 Explained

What IPX ratings mean for pool cleaners

When you compare cordless robotic pool cleaners, you will see ratings like IPX7 and IPX8 in the specifications. These are Ingress Protection codes that describe how well a device is sealed against water. Pool cleaners that run fully submerged need a rating that matches the conditions they will face in your pool.

Manufacturers such as Aiper and Maytronics build cordless cleaners that operate underwater without a hose or cable. Their product pages describe these units as robotic pool vacuums that clean floors, walls, and waterlines while completely submerged. The waterproof rating is the maker's way of telling you how much water exposure the unit can handle.

For a cordless model, the rating is especially important because the entire device, including the battery and motor, must stay sealed while it moves through the pool. A higher rating gives you more confidence that the cleaner can handle the pressure at varying depths.

IPX7 vs IPX8: what changes

IPX7 and IPX8 both indicate protection against immersion, but IPX8 is a higher level. An IPX7 rating generally means the device can be submerged in water up to a certain depth for a short period, while IPX8 is rated for continuous submersion at greater depth. The exact depth and duration are defined by the manufacturer and should be listed in the product manual.

For most residential swimming pools, IPX7 is often enough because the cleaner sits on the floor or climbs walls within the pool's average depth. If you have a deep end that exceeds the rating, an IPX8 model gives you more margin. Always verify the maximum submersion depth that the manufacturer specifies for your particular cleaner.

Why your pool's depth matters

The waterproof rating becomes important when you look at the geometry of your pool. An above-ground pool is typically shallower than an in-ground pool with a diving well. A cleaner rated for a limited submersion depth might not be safe in a very deep pool, even if the rating looks similar on paper.

The Pool & Hot Tub Alliance develops standards that cover safety and performance for pool equipment. While these standards do not set the IPX rating, they help ensure that products are designed with safety in mind. The World Health Organization also publishes guidelines for safe recreational water environments, which emphasize the importance of well-maintained equipment.

Always match the cleaner's submersion limit to the deepest point of your pool. If you own a large in-ground pool with a deep end, prioritize a model with an IPX8 rating or one that explicitly states a depth limit well below the pool floor.

What to look for in a waterproof pool cleaner

When you are ready to choose a cordless pool cleaner, consider the waterproof rating alongside other factors like battery life and navigation. A rating that matches your pool depth is essential, but it does not guarantee good cleaning performance on its own.

Here are the key points to keep in mind when comparing models:

• Check the maximum submersion depth in the specifications, not just the IPX label.
• If you have an above-ground pool, a moderate rating is usually sufficient. For in-ground pools with a deep end, look for a higher rating.
• Review the manufacturer's instructions for maintenance and seal care to keep the waterproof protection intact.
• Consider a model with a longer battery charge if you have a large pool, since a fully submerged cleaner will need to run the full cycle.
• Read the spec sheet carefully. A high IPX rating does not automatically mean the cleaner is suitable for all pool depths; depth is a separate figure.

Match the rating to your pool's depth

The depth of your pool is the first thing to check when you compare waterproof ratings. A cordless cleaner that is rated for a specific submersion depth will not be reliable in a pool that is deeper than that limit. Measure the deepest point of your pool, often near the main drain or the diving area, and compare that to the manufacturer's maximum depth for the cleaner.

For above-ground pools, the water depth is typically uniform and rarely exceeds 4 feet, so a moderate submersion rating is usually enough. In-ground pools can have a hopper that drops to 8 feet or more, especially in the deep end. If you have such a pool, look for a model that explicitly states it can handle those depths, or choose a higher IPX rating with a generous depth figure.

Remember that the rating is only one part of the decision. You should also consider the cleaner's cleaning path, filter capacity, and battery runtime, since a cleaner that is waterproof but cannot cover the pool efficiently is not a good buy. Review our guide on cordless pool cleaners for models that combine a strong waterproof rating with the features you need.

Maintaining your pool cleaner's waterproof seal

The waterproof rating is only meaningful if the seals are in good condition. Over time, the gaskets around the battery compartment and motor can wear, especially if the cleaner is handled roughly or stored in extreme heat.

Rinse the cleaner with fresh water after each use to remove chlorine and debris. Dry the unit completely before charging, and follow the manufacturer's guidance for winter storage. If you notice moisture inside the housing, stop using the cleaner and refer to troubleshooting tips. Proper care extends the life of the waterproof seal and keeps the rating valid.

What to pick for your pool

Questions

Is IPX8 always better than IPX7 for a pool cleaner?

IPX8 offers a higher level of water protection, so it is generally safer for deeper pools. However, you should still confirm the maximum submersion depth stated by the manufacturer, because IPX8 does not guarantee a specific depth on its own.

Can I use a pool cleaner rated IPX7 in a pool with a diving well?

It depends on the depth of the deep end and the cleaner's specified submersion limit. If the deep end exceeds that limit, choose an IPX8 model or one with a higher stated depth rating.

How do I know the actual waterproof depth for a specific model?

Look in the product manual or the manufacturer's specification sheet. The IPX rating alone does not give you a universal depth or time; you need the maker's guidance.

Do all cordless pool cleaners have an IPX rating?

Most major manufacturers list a rating, but you may find some models that only say 'waterproof' without an IP code. In that case, contact the manufacturer for the maximum submersion depth and duration.
