- Only a 1-year warranty compared to 3 years on the Swash 1400
The CL1700 is a capable, well-built bidet seat that gets the job done — ideal if you want a warm-water bidet with all the essential comforts and don’t need the advanced sterilization and nozzle customization of the flagship model.

Nozzle System: Which Cleans Better?
This is the most meaningful difference between these two seats.
The Swash 1400 uses dual stainless steel nozzles — one dedicated to rear wash, one dedicated to feminine wash — with 7 adjustable positions and 3 spray width settings.
The CL1700 uses a single stainless steel nozzle that repositions itself between rear and front wash functions.
Dedicated dual nozzles provide better coverage, reach, and hygiene isolation between wash modes.
On top of that, the 1400’s silver nanoparticle sterilization uses antibacterial and antifungal technology to keep the nozzles cleaner at a microbial level — something the CL1700 simply doesn’t offer.
Winner: Brondell Swash 1400. It’s not close. If hygiene precision is your priority, the 1400 wins this category decisively.
Wash Comfort and Customization
Both seats deliver warm water on demand, adjustable pressure, and heated seats with multiple temperature settings.
But the Swash 1400 goes further with nozzle oscillation — the wand moves back and forth during the wash for broader coverage — and adjustable spray width, letting you switch between a focused jet and a wider, gentler flow.
The CL1700 offers basic adjustability but doesn’t match the 1400’s depth of customization in this area.
If you’re someone who takes wash comfort seriously, you’ll notice these differences daily.
Winner: Brondell Swash 1400.
Dryer Performance
Both seats include a warm air dryer, which is essential if you want to reduce or eliminate toilet paper use.
The Swash 1400’s dryer is well-regarded by owners, delivering enough warmth for practical drying with regular use.
The CL1700’s dryer has attracted more criticism from buyers — multiple reviewers have described it as underpowered, sometimes requiring more than one cycle to finish the job.
If going paper-free is important to you, this matters.
Check out our guide to the best bidets with warm water and dryer to see how both compare to the broader market.
Winner: Brondell Swash 1400.
Installation and Fit
Both the Swash 1400 and CL1700 are designed for self-installation in under an hour, with no plumber required.
Both are available in elongated and round versions to fit standard North American toilets, and both require a standard 120V GFCI outlet within reach of the toilet.
The CL1700 has a slightly higher seat weight capacity at 330 lbs vs the 1400’s 270 lb sittable lid limit, which may matter for some users.
Neither seat fits toilets with a “French curve” design where the tank meets the bowl on a slope — something to check before you buy.
For more guidance on fitting a bidet to your existing toilet, see our article on the best bidets for existing toilets.
Winner: Tie. Installation is nearly identical; the CL1700 has the edge on seat weight capacity only.
Long-Term Value and Warranty
The Swash 1400 comes with a 3-year limited manufacturer’s warranty.
The CL1700 comes with a 1-year warranty — three times less coverage.
Given that a bidet seat is something you install once and use every single day, the warranty gap is significant.
The 1400’s replaceable deodorizer filters also give you better long-term hygiene performance — you can swap the filter when it loses effectiveness, rather than living with a declining deodorizer.
If you’re thinking about the full cost of ownership over 5–10 years, the Swash 1400 is the more durable and better-supported investment.
Winner: Brondell Swash 1400.
Verdict — Which One Should You Buy?
Both are quality electric bidet seats from one of the most trusted names in the category, and either one will be a meaningful upgrade over a standard toilet seat.

This is the seat for people who want premium performance and long-term confidence in their purchase. If you want to see how it compares across the broader market, our guide to the best heated bidet toilet seats is a great next read.

It’s a capable, well-built seat that delivers everyday comfort without the flagship price tag.
Frequently Asked Questions
Is the Brondell Swash 1400 worth the extra cost over the CL1700?
For most buyers, yes. The Swash 1400’s dual nozzles, silver nanoparticle sterilization, spray width adjustment, and 3-year warranty represent meaningful real-world upgrades — not just spec-sheet differences. If hygiene precision and long-term durability matter to you, the 1400 justifies the price gap.
Do both seats work with round and elongated toilets?
Yes. Both the Swash 1400 and CL1700 are available in elongated and round versions. Make sure you select the correct size for your toilet bowl before ordering. For a detailed rundown of what to look for with round toilets specifically, our guide to the best bidets for round toilets has everything you need.
What is silver nanoparticle nozzle sterilization on the Swash 1400?
It’s a hygiene system unique to the Swash 1400 that infuses water with silver nanoparticles — a material with natural antibacterial and antifungal properties — before it flows over the nozzles. This actively sterilizes the stainless steel wands rather than simply rinsing them with water, as the CL1700 does. It’s one of the more advanced hygiene features in the consumer bidet seat market.
Can both seats reduce toilet paper use?
Yes, and that’s one of the best reasons to make the switch to an electric bidet seat. Both models include a warm air dryer designed to reduce or eliminate toilet paper use. That said, the Swash 1400’s dryer consistently earns better reviews from owners than the CL1700’s. If paper-free is a firm goal, the 1400 is the stronger choice.

Conclusion
The Brondell Swash 1400 and CL1700 share the same brand DNA — clean design, warm water, wireless remote, and stainless steel nozzles — but they’re built for different buyers.
The CL1700 is a solid entry into the premium electric bidet category. It covers the essentials, installs easily, and delivers real comfort every day.
But the Swash 1400 is in a different league when it comes to hygiene precision, wash customization, dryer performance, and long-term warranty coverage.
If you’re investing in a bidet seat that you’ll use twice a day for the next decade, the Swash 1400 is the one to buy. Start with our guide to the best bidets for home use if you want to explore your full range of options before deciding.
