Good to Go With Shabbatto!

Kashrus Kurrents, Spring 2022

People look forward to Shabbos as a day to daven in shul and enjoy
the company of other Shomer Shabbos members of the community. Unfortunately,
there are people with mobility issues who are housebound on Shabbos and, for
them, Shabbos is a lonely day. But thanks to newly developed technology by
Movinglife, an Israeli firm, the housebound now are afforded a new opportunity
to rejoin the tzibbur and to enhance their enjoyment of Shabbos. We are
very excited to announce STAR-K certification of the Shabbatto folding scooter,
a new personal mobility device with a Shabbat Mode option.

The road to certification began with Movinglife contacting STAR-K
to discuss their project. After approaching STAR-K to seek certification, the
Movinglife management team met with Rav Moshe Heinemann shlit”a, STAR-K’s

One is permitted to arrange a ring of water around a fire, even though the fire will certainly be extinguished when it reaches the water.1 This is halachically allowed due to the time delay between the action of arranging the water and the subsequent melacha of extinguishing the fire on Shabbos. Similarly, any activity that includes a time delay between a person’s action and the ensuing melacha would be categorized as a grama.2 Grama of a melacha de’oraissa is permitted only in situations of financial loss.3 However, […]

All About Sabbath Mode and Sabbath Compliant Appliances

Updated January 2023

Appliance manufacturers, with the aid of modern technology, have designed kitchen appliances to be safer and more efficient while incorporating various features to enhance operation. However, the integration of this technology may pose a challenge to their proper use on Shabbos and Yom Tov.

THE INTRODUCTION OF SABBATH MODE

In 1997, a historic technological project was launched between a major appliance manufacturer and a kosher certification agency. Whirlpool Corporation (manufacturer of KitchenAid) approached STAR-K to help modify their ovens for use on Shabbos and Yom Tov. Prior to that time, many of their appliances did not conform to halachic guidelines.

Following some adjustments, a successful mode was developed. Whirlpool called this “Sabbath Mode” and was awarded a patent in 1998 for this concept.

STAR-K kosher certification on appliances falls into one of two categories:

1. Sabbath Mode Appliances – these are models that have unique software/hardware specifically engineered to address the […]
