Robot v suction pool cleaners: 5 reasons why it’s better your cleaner sucks

It’s the age old question, robot v suction cleaner? 

We’ve cut through the muck to give you the lowdown. Let’s dive in and see how they stack up.

Suction versus robot pool cleaners

Both robotic and suction pool cleaners do the same job – automatically clean the pool so you don’t have to. 

But there is one significant difference between them. 

Premium suction pool cleaners like the Kreepy Krauly’s use the vacuum effect of the pool’s filter to power its working parts, sucking up litter and sending it to the skimmer box or filter. 

A robot pool cleaner on the other hand uses an independent electrical power supply, patrolling the pool to suck up debris into an internal storage tank. 

This one crucial difference in power supply creates a number of important differences for pool owners to consider.

Less work

Because the robot pool cleaner uses an independent power supply instead of the pool’s filter, it is not able to send its debris back to the skimmer box or filter through a hose connection.

This means pool owners have to regularly remove the entire robot pool cleaner from the water and empty its internal debris storage tank.

Robot pool cleaners can be heavy – some weight more than ten kilos – so pulling them out of the pool can be a hard job, especially if the device’s storage tank gets filled up quickly.

In contrast, a suction cleaner like the Kreepy Krauly can stay in the pool all year round, sucking up debris that can be easily collected from the pool’s skimmer box or filter.

Power cut

Even the most modern, energy efficient pool filter still uses a decent amount of electricity, especially when its regular cycles are all added up in your power bill.

When you choose a suction pool cleaner like a Kreepy Krauly, that energy bill is never added to, because the pool filter’s suction effect powers the cleaner.

But a robotic pool cleaner needs its own power supply, whether its battery operated or plugged in, meaning another running cost gets added to your pool’s maintenance routine.


A suction cleaner like the Kreepy Krauly sends water from all over your pool, from the bottom and sides of your pool to your custom designed filtration and sanitation system, returning it clean and fresh to the top of your pool. This creates proper pool circulation.

In contrast, robot cleaners collect debris and are limited to the filtration their bags or cloth filters offer. They assist in floor and side water movement, working independent of the pool’s filtration system, taking and returning water from the top of the pool.

They do offer the ability to create programmable cleaning patterns, but that extra water filtration that you get with a suction device is just not possible.

Show me the money

Robot pool cleaners can be expensive – many retail for more than $2,000 dollars, and even basic models can cost at least a thousand dollars.

In contrast, premium suction cleaners like the Kreepy Krauly can cost as little as five hundred dollars.

And with extra power supply needed – not to mention the extra lifting and shifting to empty the storage area – robot pool cleaners can end up costing much more than you paid, especially if their complex parts ever need a repair.

The verdict

If you’re still interested in going down the robotic path, products like Kreepy Krauly’s innovative new rX-Tank combine the best of both worlds for suction and robots, all with an affordable price tag.

The rX-Tank features unique robotic X-Over (crossover) technology that combines the intelligent programming of a robot pool cleaner with the convenience and energy efficiency of a suction unit.

Best of all, just like a regular Kreepy Krauly, the rX-Tank is designed to stay in the pool 365 days of the year, with minimal intervention by pool owners.

A crossover model like the rX-Tank offers the best features of robotic and suction cleaners so you can get on with the most important thing – swimming in a sparkling clean pool.
