A new pack of replacement heads for an electric toothbrush may seem easy to choose. Yet many households order the wrong model, pay for features they do not use or keep too many heads for too long. Especially when it comes to Philips Sonicare replacement heads and Oral-B replacement heads, the brand alone is not enough: the connection, handle and intended use all need to match.
This buying guide will help you compare replacement heads in practical terms. We also cover replacement heads for adults, replacement heads for children and maintenance parts for a Clean X9 Pro robot vacuum.
Philips Sonicare and Oral-B use different attachment systems. There are also exceptions within each brand. For example, according to the product information, Oral-B Precision Clean replacement heads are suitable for many rechargeable Oral-B handles, but not for Pulsonic and iO models. According to the specifications, Philips Sonicare HX6066/87 is not intended for Philips One.
Therefore, always check:
A head that almost fits is not a safe saving. Only use an electric toothbrush attachment when manufacturer compatibility is clearly confirmed.
A 6-pack may automatically appear better value than a 4-pack of toothbrush heads, but this depends on the number of users and how often the heads are replaced. A brush head is generally replaced after around three months, or sooner if the bristles are bent, damaged or worn.
For one adult, a 6-pack could therefore last around a year and a half. For two users, the same quantity will run out much sooner. Store spare heads in a dry place and check the packaging, so you do not buy more than you can realistically use.
Brands sometimes quote percentages for plaque removal, discolouration or gum health. According to Philips’ own research, certain Sonicare heads may, for example, show specific improvements compared with a manual toothbrush. Such figures are brand claims based on the brand’s own research conditions and are not a guarantee for every user.
Instead, focus first on verifiable details: bristle softness, shape, number of heads, replacement indicator and compatibility. If you experience irritation or persistent discomfort, stop using the product and ask your dentist for advice.
Philips Sonicare brush heads with a click-on connection are designed for compatible Sonicare handles. Models such as the Philips Sonicare ProResults HX6014/87 and HX6016/87 are described in the product information as suitable for Sonicare handles with a replaceable head. The HX9094/87 A3 Premium All-in-One is a 4-pack for compatible Philips Sonicare electric toothbrushes.
With Oral-B, the shape is often round and rotating. According to the product details, the Oral-B EB20-4 Precision Clean Refills are suitable for rechargeable Oral-B toothbrushes, except Pulsonic and iO. For Oral-B Pulsonic, you need a specific model instead, such as the SR32C-8.
Soft or extra-soft bristles are a practical choice if you are looking for a gentler brushing experience. The A3 Premium All-in-One is listed with soft bristles. The Oral-B Pro Kids uses extra-soft nylon bristles and a round head for smaller mouths.
An interdental toothbrush is different from a replacement head for an electric toothbrush. The Reach Interdental Toothbrush Medium has a narrow, tapered head for cleaning between the teeth and along the gumline. It is a standalone manual toothbrush and does not fit an electric handle.
Some Philips heads have blue bristles that gradually turn white. On certain Oral-B heads, an indicator changes from green to yellow. This helps you assess wear without relying on feel alone.

If you are looking for robot vacuum accessories as well as toothbrush heads, first check the exact model. According to the product specifications, the Clean X9 Pro ACS Repl Kit is intended for the Clean X9 Pro and eufy RoboVac X9 Pro series. The set includes a main brush, side brushes, filters and mop pads, among other parts.
When fitting the parts, follow the instructions: switch off the robot, remove it from the charging station and check that the brushes and guards click securely into place. Do not wash HEPA filters unless they are explicitly stated to be washable. Keep small parts out of children’s reach.
We have put together a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.
Many manufacturers recommend replacing it approximately every three months. Replace it sooner if the bristles are splayed, bent or damaged. A replacement indicator can help, but you should also inspect the head yourself.
Not automatically. Check whether your handle has a compatible click-on connection and look out for exceptions, such as Philips One with certain Sonicare models. The model number on the packaging is the deciding factor.
Choose a head specifically intended for children and follow the age guidance. The Oral-B Vitality Pro 103 Kids Lion King is listed for children from age 3, under supervision. Standalone adult heads are not automatically suitable for a child’s mouth.
