The Main Differences 

Best Water Heater: SWASH 1000 

So, the biggest difference between the two bidets is the type of water heater. 

Despite being thought of as a luxury option, the USPA 6800 has a tank-type heater. If you’re new to the subject, this type of heater stores water in a warm tank for use on demand.  

The tank is about 2-½ cups. At a flow rate of 0.9L/min, the warm water lasts about 40 seconds at which point the water stream starts to cool off. The water remains heated, but drops to the low 90’s F.

Interestingly, when they upgraded the 6800 to the 6800U, they kept the old-style heater, not even giving the bidet a tankless type heater.

The tankless ceramic core heater of the Brondell S1000 heats water instantaneously, so it never runs out. You can spray till the cows come home and get warm water to the last drop. 

Best Wireless Remote: USPA 6800U 

The old-style USPA 6800 remote was pretty fancy too, being one of the first to have an LCD screen. But, in upgrading to the 6800U, they made the remote double-sided, so the user could have even more control. 

An LCD screen lets you do more with fewer buttons, making more room for more controls. The double-sided design allows for even more options. Hence, you get a bidet that allows for all these extra spray features and options we’ll be getting into shortly. 

The Brondell S1000 remote is nice and definitely has its advantages. For one, it’s less complicated with larger intuitive buttons, making it easier to use for kids and senior adults who maybe don’t want to fool with all the extra bells and whistles.  

Best Nozzles: SWASH 1000 

This isn’t a huge deal, in my opinion, but it’s important for many users, so it’s worth mentioning.  

Both bidets have dual nozzles (one for the front/one for the rear) for both rear and front feminine hygiene. 

But the S1000 nozzles are made of stainless steel while the USPA 6800/6800U nozzles are made of plastic.

The plastic is high-quality, like with the rest of the bidet, and nozzles don’t see a ton of wear. But anything made with stainless steel is going to be more durable and thus add to the lifespan of the bidet. 

Best Hygiene Sanitation: SWASH 1000 

This is a big selling point, especially for those who are wary of bidets due to fears of getting an infection. Bidet use isn’t associated with infections, but it’s still a possibility (as it is with toilet paper). 

Both bidets have automatic self-rinsing nozzles, meaning the nozzles self-clean before and after each use, without the user having to hit a button. 

But the SWASH 1000 has an on-demand self-sanitizing function. As an extra layer of protection against infection, the sanitation function triggers a 30-second nozzle rinsing session that uses Silvernado, a patented silver oxide solution. Silver has natural antibacterial and antifungal properties. 

The USPA 6800 and 6800U Have a Child Mode 

The USPA 6800/6800U has a child wash mode to make the bidet easier to operate and more comfortable for younger users. 

The child presses a single button to get a wash/dry cycle with child-friendly settings like an extra-extended nozzle (for shorter stature) and lower water pressure. 

The USPA 68000 and 6800U Have a One-Push Auto Mode 

Using an auto mode is like ordering a #3 off the menu instead of specifying everything you want separately. 

When operating the cleansing mode, press the ‘A’ button and get 20 seconds of basic cleansing, 20 seconds of oscillation cleansing, and 20 seconds of massage.  

The USPA 6800U Has User Presets 

This feature lets you save some of your preferred settings.  

It’s another upgrade they made with the 6800U (the original 6800 didn’t have the feature). 

You can only save your favorite water pressure and nozzle position, so it’s not the most elaborate I’ve seen. But that’s two fewer buttons you have to push each time. 

The USPA 6800U Has a Built-In Nightlight 

The last change they made when making the 6800U was to add a nightlight. So, the Brondell SWASH 1000 and original BB USPA 6800 both lack this feature. 

It’s a nice touch. It might seem frivolous, but it’s a great feature for folks who make regular trips to the restroom at night.  

On top of looking cool, it illuminates the restroom just enough so that you can make your way to the bidet and use it without tripping or blinding yourself with bathroom lights. 

The SWASH 1000 Has Adjustable Spray Widths 

I’m not sure why, but this is a rare feature. 

The S1000 lets you choose your spray width: narrow, standard, and wide. The narrow spray is concentrated, in effect, providing the “turbo” mode you see with most bidets these days.  

Strong spray settings clean more effectively and are known to help with constipation. 

For greater coverage or a softer cleanse, choose the wide spray setting. The wide setting is nice for frontal cleansing and soothing irritated skin (as with hemorrhoids).  

The USPA 6800 and 6800U Have a Massage Mode 

Massage spray modes typically pulse or rotate soft and strong pressure for a soothing massage-like effect. 

With the 6800 and 6800U, the massage setting is a variation of the oscillation setting, in that it oscillates the nozzle in a regular rhythmic pattern.  

The USPA 6800/6800U can still pulse water, which brings us to the next point. 

The USPA 6800 and 6800U Have an Enema Mode 

The USPA 6800 and 6800U have an enema mode called the impulsive impulse pulsation setting (IIP)–I guess all the good names were taken. 

Anyway, it’s a neat feature because it pulses high pressure to help stimulate bowel movement for relieving constipation.  

High pressure helps constipation in a couple of ways: one is by entering the rectum and the other is by massaging the area around the external sphincter to stimulate bowel contraction.  

The max pressure setting with the S1000 can also be used for a makeshift enema, but the concentrated pulsing spray of the IIP is made specifically for stimulating BMs.  

The Brondell S1000 Is More Energy Efficient 

The Brondell S1000 is way more energy efficient. The internal ceramic core heater uses 60% less energy than traditional tank-type heaters like the kind found with the USPA 6800/6800U

Now, the USPA 6800/6800U does have an Eco power-saver mode to help cut down on power use. But it’s not the sophisticated kind that memorizes when the bidet is less likely to be used. Instead, it functions on-demand.  

So, to use it, you’ll have to get accustomed to room-temp water and a cold bidet seat surface. 

The S1000 has a similarly ineffective Eco mode, but the difference is that you won’t need it with the S1000. It uses little energy at full power and even less at rest.  

Features and Specs: Bio Bidet USPA 6800U vs Brondell CS1000 

The Brondell SWASH 1000 

Brondell S1000-EW Swash 1000 Advanced Bidet Elongated Toilet Seat, White

I don’t say this often, but, in this case, the more expensive bidet is actually worth it. So, I’d recommend the Brondell SWASH 1000 (compare price on Amazon).  

It doesn’t always work out that way. For example, the BB A8 Serenity costs way more than the USPA 6800U, but I’d take the 6800U any day.  

But the Brondell S1000 is the clear winner in this comparison. It’s the second-best bidet put out by one of the best companies—for Brondell bidets, it’s second only to the SWASH 1400.  

For one thing, the tankless water heater will pay for itself in energy savings. A bidet with a classic tank-type heater (like the USPA 6800U) can cost a few bucks a month to operate while tankless heaters cost a few cents.

That coupled with the endless warm water and Silvernado wand sanitizing function, the choice is made easy. 

Features and Specs

Water Temperature: 

  • Ceramic core heater for instant and limitless warm water. 
  • Adjust the temperature to 1 of 4 settings for each wash mode: “Off” (cold tap), Low (88.7° F), Medium (94.1° F), and High (99.5° F). 

Water Pressure: 

  • Adjustable water pressure with 3 strength settings. 
  • The flow rate maxes out at 0.13 gal (or ~0.5 L) per minute. 
  • There’s no wash mode labeled “strong” or “turbo” but the spray width can be adjusted to extra-narrow for a more concentrated spray. 

Comfort and Convenience: 

  • Wireless handheld remote control with easy-to-use buttons, a magnetic dock/mounting bracket, and low-power battery-saving mode. 
  • A warm air dryer with adjustable temperature (not a feature of the lesser Brondell S1200).  
  • Heated seat with 4 adjustable temperature levels.  
  • Aerated wash for added comfort. The S1000 incorporates air bubbles into the water for a softer yet firmer cleansing spray. 
  • Deodorizer: a common feature with luxury bidets is an air deodorizer. A small fan circulates air from the toilet bowl through an activated charcoal filter that breaks down and expels stinky molecules. This is another feature missing in the lesser S1200 but included in the S1000 and S1400. 
  • A low seat height of 5.7” (14.5 cm) for a low-profile look and comfortable sitting experience. 

Seat and Lid: 

  • Gentle, slow-closing seat and lid for increased bidet longevity. 
  • Quick-release button at the back of the seat for easy bidet removal and cleaning. 

Cleaning Wand and Sray Capability: 

  • Dual (separate) stainless-steel nozzles, one for regular cleansing and the other for front feminine hygiene. 
  • Both cleaning wands are adjustable to 5 positions for accurate aiming. 
  • Oscillating spray setting for a more thorough wash and wider coverage area. Oscillating nozzles move back and forth so the user doesn’t have to shift around to hit all the right spots.  
  • Adjustable spray width. You can choose 1 of 3 width settings to take the spray from strong and concentrated to soft and soothing.  
  • The narrow spray setting can be used for constipation relief by allowing water to enter the rectum. 

Safety and Sanitation: 

  • Automatic self-cleaning wands. 
  • On-demand self-sanitizing nozzle function. The silver oxide-containing antimicrobial agent sterilizes the wands without causing corrosion. 
  • Safety seat sensor to prevent unwanted bidet operation. 

Energy and Water Efficiency: 

  • Heater type for 60% energy savings. No drawing energy 24/7 to keep a reservoir warm. 
  • The SWASH Eco mode turns the seat temperature down 10 minutes after the bidet was last used.  
  • Aerated wash reduces overall bidet water consumption. 

The Bio Bidet USPA 6800U

If you’re looking to keep costs to a minimum, the Bio Bidet USPA 6800U is a great choice (compare price on Amazon). 

I consider it a premium (mid-tier) option despite the basic tank-type heater because it has so many neat features. For example, it has an air deodorizer like the S1000, which is a feature typically absent with bidets in this price range.

Besides saving money, the bidet offers a few features lacking in the Brondell S1000.  

The S1000 is better overall, but 6800U has a fancy remote, child wash mode, massage spray setting, user presets, an auto mode, and enema function for constipation relief. 

If you’re torn and want a bidet that’s the best of both worlds, I’d suggest going with the Bio Bidet DIB Special Edition* (article link), since it combines the best features of both for a price similar to the Brondell S1000. 

As mentioned, you can still find the USPA 6800 original, but it’s the same price (sometimes more expensive) despite having fewer features. Compared to the 6800U, it lacks presets and a nightlight and has an old-style remote. 

Features and Specs 

Water Temperature: 

  • Tank-type heater with ~2-½ cup reservoir, offering 40 seconds of warm water flow and about a minute of warm to lukewarm water overall.  
  • 4 temperature levels for each wash mode. 
  • The temperature ranges from “Off” (cold tap) to the highest of 104° F. 

Water Pressure: 

  • Adjustable water pressure w/5 settings. 
  • A flow rate that maxes out at 0.24 gal (or ~ 0.9 L) per minute.
