A cordless, rechargeable flosser with two nozzles in this box
HX3826/21 is the white Philips Sonicare Cordless Power Flosser 3000 with two nozzles. The manual covers both the 2000 and 3000 Series and lists HX3826 among the 3000 Series models, so check that the option you pick carries this product code.
The listing's box contents are the flosser, one F1 Standard nozzle, one F3 Quad Stream nozzle, a USB-A charging cable and a wall adapter. The manual's charger note says to use only a 5V IPX4-rated adapter or the listed Philips adapters, so keep the supplied one.
A 250 ml tank sized for one 60-second session
The removable reservoir holds 250 ml. The listing and the Philips product page both say that is enough for a full 60-second session in Clean mode and up to 90 seconds in Deep Clean mode. The manual says not to use hot water in it.
The listing describes a QuadPacer that pauses every 15 seconds to move you around the mouth, and the manual says the pacer can be turned off. The manual also says the flosser switches itself off after two minutes, so a longer routine means restarting it.
Two modes and three intensities, with no pressure figure
The 3000 Series has Clean and Deep Clean modes, and a separate button steps through three intensity settings, which the listing counts as three pressure levels. The manual describes its recommended one-minute routine, so read that page rather than the listing's summary.
Both nozzles in the box, the F1 Standard and the F3 Quad Stream, are consumables: the manual says to replace them every six months or when damaged, and the two-year warranty excludes them. No pressure figure in PSI appears in any source we read.
Battery life: 40 days in the listing, 25 sessions in the manual
The listing and the Philips product page advertise up to 40 days of battery life, footnoted as one one-minute session a day. The manual says the flosser is designed to provide at least 25 one-minute sessions per charge, and at least three more once the low-battery light shows. Plan on the manual's lower figure if the flosser is shared or used twice daily.
Charging uses the USB-A cable and a 5V adapter; the manual says a full charge can take up to eight hours. Charge and use it between 5°C and 40°C. The lithium-ion battery is not user-replaceable.
Water rating and the manual's dishwasher contradiction
The listing says the flosser is IPX7 waterproof and bathroom-friendly. The manual pages we read give no IP rating for the handle, and the Philips product page text did not state one either. Treat the IPX7 figure as a listing claim that the maker documents we read do not repeat.
The manual contradicts itself on cleaning: its safety list says not to clean any part of the product in the dishwasher, while its cleaning section says the reservoir can go on the dishwasher top rack. The manual asks for weekly cleaning; follow its printed routine and, given the contradiction, hand washing is the safer reading.
Two-year warranty that excludes nozzles
The manual says Philips warrants the product for two years from purchase, repairing or replacing defects in materials and workmanship with proof of purchase. Nozzles, damage from unauthorized parts or nozzles, misuse, and normal wear such as scratches or fading are excluded. The product page also shows a two-year warranty badge.
The manual says to replace nozzles every six months or when damaged. It also lists situations in which to consult a dentist or doctor before use; that list is in the manual, not repeated here, so read it before starting if you have any medical condition or device.
