FSA2400 Advanced
Limited evidenceRead the findings →BWT's top corded pool robot, with a fine microfibre filter and a design-led look. It's aimed at large in-ground pools, with nothing to set up. The catch: there's no app or timer, so you plug it in each time.

What we know
Per the BWT product page, the FSA2400 Advanced cleans the floor, walls and waterline in two hours, scrubs with four foam brushes and a vibrating brush, and traps dirt in a vibrating 4D microfibre filter. The BWT shop listing describes the same robot. BWT itself gives two figures for the largest pool it suits, 12 and 15 metres. Beyond BWT's pages, we found only retailer listings.
12 or 15 metres?
The headline on the BWT page says it cleans pools of all shapes up to 15 metres, and the BWT listing says the same. The technical table on that same page gives a maximum of 12 metres, and adds that a two-hour run handles up to 40,000 litres. If your pool is longer than 12 metres, ask BWT or the dealer which figure applies before you buy.
Built around fine filtration
Per BWT, the 4D filter is made of elastic microfibre loops that vibrate to keep water flowing, and catches everything from leaves to grains of sand. Adjustable nozzles let you bring the suction closer to the surface for stronger pickup. It scrubs with four foam brushes and a vibrating brush, and BWT lists 20 cubic metres an hour of suction.
Upkeep and wall-climbing tips
BWT's BWT FAQ says to clean the filters after every use and check the drive and suction motor for debris. If it stops climbing walls, BWT suggests cleaning the filters, removing algae or deposits from the walls, shock-chlorinating and checking the handle position. It's rated for depths up to 4 metres, and for salt water up to 4,000ppm as long as you rinse it in fresh water afterwards.
What's not checked yet
No independent reviewer has put this model in a pool and published a finished verdict. So the basics are open: how well it covers the floor, climbs walls, handles steps and copes with leaves, and whether the 4D filter and suction live up to BWT's figures. The BWT page explains the design and upkeep, and nothing more.
Our take
Should you buy the FSA2400 Advanced?
Best for: Large in-ground pools needing floors, walls and the waterline cleaned. Skip it if: You want a stronger record in independent tests before buying.
It might suit a large in-ground pool in Europe if you like the design and want a plug-in robot with nothing to configure, but there's no test to back it up. If you want a corded robot with proven results, the Dolphin Nautilus CC Plus impressed three testers. If you'd rather lose the cable, the cordless Dolphin Liberty 600 did well in two tests.
The FSA2400 Advanced is the top model in BWT's design-led FSA range, above the FSA1500. It plugs into the mains through a 16-metre cable with a swivel, and cleans the floor, walls and waterline in two hours. It scrubs with four foam brushes plus a vibrating brush, traps dirt in a 4D microfibre filter that vibrates to stop it clogging, and steers with a gyroscope. Pink lights pulse in time with the pump.
The trade-offs are control and pool size. There's no app or timer, and BWT's own page says both 12 and 15 metres for the largest pool it suits.
It's sold mainly through BWT's European shops and dealers.
Before you buy
The questions people ask about this one
Does it climb walls and clean the waterline?
BWT lists floor, wall and waterline cleaning, per the specifications. Its FAQ says a robot that stops climbing usually needs clean filters or algae-free walls. We found no independent test of how well it climbs.
Does it need an app?
No. BWT's spec table lists no app control, per the specifications, and it runs a two-hour cycle when you switch it on. There's no timer or scheduling, so you start each clean yourself.
How do I clean the filter?
BWT says to clean the filters thoroughly after every use, and to unplug the robot first, per the specifications. It hasn't said how long the microfibre 4D filter takes to rinse, and we've seen no tester report on it.
Can it cope with steps and a deep end?
BWT rates it for water up to 4 metres deep and for PVC, ceramic, stainless steel and polyester pools, per the specifications. It doesn't say whether it climbs steps, and we found no test of it.
Alternatives
Other robotic pool cleaners to compare.
Nautilus CC Plus
Why consider it: Three independent testers found it cleans floors and walls quickly, with filters that are easy to empty.
The compromise: It sometimes sticks on steps, and testers disagree about whether it cleans the waterline.
LIBERTY 600
Why consider it: Two testers found this cordless Dolphin leaves floors very clean, filters well and comes up when you shake the clicker.
The compromise: It wanders at random, and one tester found its step jet shifted only part of the dirt.
AquaVac 650
Why consider it: Another corded robot with Wi-Fi control, and both testers praised its cleaning and filterless canister.
The compromise: Neither tester could make its tug-the-cable recall work.
