What the blue Cordless Pulse 3100 is
This is Waterpik's handheld cordless flosser in the blue finish, model WF-20CD013, and Waterpik's own page for that model number confirms the colour. It is a one-piece unit: the reservoir sits on the handle rather than on a base, so there is no hose and nothing to leave on the counter beside the sink.
The listing gives the reservoir as 6 fluid ounces with up to 45 seconds of flossing per fill, and the body as 3.7 by 2.5 by 11.88 inches at 10.4 ounces. Waterpik's page gives the reservoir capacity in time rather than volume, as up to 45 seconds, and describes the design as portable, extra quiet and waterproof.
Two tips come in the box according to the listing: a Precision tip, JT-450E, and a Tongue Cleaner, TC-100E. Waterpik's page says two flossing tips and a pressure control system with two settings, which is the low and high switch on the handle rather than a dial.
Charging: the adapter is not in the box
The Instructions for Use are specific about what will charge this unit: a user-supplied USB-C wall charger, safety certified to IPX4, with a rated output of 5.0 volts at 3.0 amps maximum. Waterpik's page says the USB-C cable charges from a laptop, car, power bank or wall adapter, and states plainly that the wall adapter is not included.
Waterpik asks for a four-hour charge before first use and says a full charge lasts up to nine weeks with typical use. The listing repeats the nine-week figure. The charging light tells you where you are: flashing white as the battery approaches low, solid red when it is depleted, glowing while charging, and solid once full until the cable is unplugged.
One habit matters more on this model than on a plug-in one. The instructions say to remove the charging cord and put the charge port cover back before filling the reservoir, and to make sure the cover is flush with the handle during use. They also ask that the contacts on the cord, the unit and the adapter are clean and dry while charging.
Using it: two settings and a switch
Pressure is not a dial here. The handle switch runs off, low and high, and the instructions say to use low on first use. Neither the instructions nor Waterpik's page lists a timer or a pacer for this model, so the 45-second reservoir sets the session length.
The instructions ask you to press the tip firmly into the unit until it clicks, and caution against pressing the tip eject button while the unit is running. They also say to keep the unit upright during use, and print a short technique section best read in Waterpik's own document.
One small piece of advice from Waterpik that is easy to miss: when you finish, remove the tip from the unit, which the instructions say lowers the risk of the unit being knocked over. Filling is through a flip top on the reservoir with lukewarm water.
Tips, cleaning and hard water
The WF-20 Series replacement table gives three months for the Orthodontic tip OD-100E, the Pik Pocket tip PP-100E and the Plaque Seeker tip PS-100E, and six months for the Precision tip JT-450E and the Tongue Cleaner TC-100E. Both tips in this box therefore fall in the six-month column.
Never immerse the unit. Before cleaning, Waterpik says to disconnect the charging cable and replace the charge port cover, then wipe the exterior with a soft cloth and a mild non-abrasive cleanser. The reservoir comes off, is top-rack dishwasher safe with air drying recommended over a heated cycle, and Waterpik suggests removing and cleaning it weekly.
For hard water, the instructions give a white vinegar and warm water run-through every one to three months with the proportions printed in the document. They also say not to use iodine, saline or water-insoluble concentrated essential oils, and set a usage limit of five minutes in any two-hour period.
Shower use, temperatures and the battery
The listing says the product can be used in the shower and adds that the manual's warnings on that point apply only if the corresponding symbol appears on this item's labels and packaging, which it says it does not. Waterpik's page also describes the unit as waterproof and says it may be used in the shower. The instructions' symbol glossary lists an ingress protection code and a do-not-immerse symbol among the symbols that may appear, so check the markings on the unit you receive.
Battery care has numbers worth knowing if the unit will live in a bathroom or a suitcase. Waterpik gives an operating range of 41 to 104 degrees Fahrenheit, a charging range of 41 to 95 degrees, short-term storage including transport from 14 to 140 degrees, and recommends long-term storage in a cool dry place between 50 and 77 degrees, out of direct sunlight.
The lithium-ion battery is not replaceable. Waterpik says it should be removed only at end of product life for recycling, and that the removal process is not reversible and voids the warranty. If the flosser will be stored for six months or more, charge it fully first.
Two-year warranty and its limits
Water Pik warrants the product to the original consumer against defects in materials and workmanship for two years from the date of purchase, and will ask for the original receipt and, if requested, the whole product. It replaces at its discretion rather than repairing. The listing's warranty field and Waterpik's page both say two years.
Accessories and consumable parts such as tips are excluded, use with improper voltage voids the warranty, and cover does not apply if the product was abused, misused, altered or damaged after purchase or used with accessories Waterpik has not approved. The instructions also state that Waterpik does not guarantee the availability of replacement parts, repair services or repair information.
The document includes a binding arbitration clause with the American Arbitration Association, Colorado as the venue, and a waiver of class actions. Read that section in Waterpik's own document before you buy if arbitration terms matter to you.
